- Bugscope Teamsample is now in 'scope and pumping down
- 6:52 am
- 6:58 am
- 7:04 am
- 7:09 am
- Bugscope Teamnow we're making presets...

- Bugscope TeamHello there!
- Bugscope TeamWelcome aboard!
- Bugscope TeamThis is how you can ask questions about what you are seeing.
- Bugscope TeamHi!
- Bugscope TeamYay!
Bugscope TeamCan you see our responses? I hope so.
- Teacherwhat are the 2 round things on the left
- Bugscope Teamthose are palps
- Bugscope Teamthey help the insect taste and also manipulate its food
- Bugscope Teamthis is some kind of aquatic insect larva Cate put on last night.
Bugscope TeamIts probably some kind of dragonfly nymph. I've never seen palps like that on one though.
- Bugscope Teamthey're like feelers that have a sensory function and also help move food into the mouth, if there is a mouith
- Bugscope Teamthis is a spider with a kind of fringe on the front of its head, quite stylish
- Bugscope TeamNice spider. You can see some of the eyes in the upper right.
- Teacherwhat are palps
Bugscope TeamThey are roughly analogous to our tongue. They both move food around, and help it taste.
Bugscope Teamthe typical insect has 4 palps, two maxillary and two labial palps, although some have less and others have palps that are greatly modified
- Bugscope Teamthe fangs are in the middle, at the tips of the chelicers
- Bugscope TeamIf you want to see more of the spider, you should be able to zoom out using the "-" sign by the word "Magnification" at the top of your page.
- 8:15 am
- Bugscope TeamThese large rectangular looking structures are the Chelicerae
- Bugscope TeamThe ends of the chelicerae are where the fangs are attached. you cant see them too well because they are folded in.
- Bugscope TeamYou can also move down the spider, by just clicking on the image.
- Bugscope Teamspiders use their fangs and chelicerae to inject venom and digestive enzymes into their prey. their actual mouth is not much more than a tube so they cannot chew their food and must predigest it outside of their body. The hairs that Scott or Daniel mentioned earlier act as a filter, preventing any solid food material from entering and clogging their mouth opening while allowing liquids to pass through.
- 8:33 am
- Bugscope Teamthis is awesome
- Bugscope Teamwho's driving? is this Mrs Prince?
- Bugscope Teamwe're looking at the capitulum
- Bugscope Teamwhich includes the palps, on either side, and the hypostome, in the middle
- TeacherWHERE ARE HIS hER? EYES
- 8:38 am
- Bugscope Teamthere are no eyes, but there are eyespots on the back of the head
- Bugscope Teamthere is another tick in here, and you can clearly see its eyespots, whereas on this one we cannot see them at all
- Bugscope Teamwe're looking right into the mouth
- TeacherIS THIS THE FRONT OF THE HEAD?
Bugscope Teamyes it is!
Bugscope TeamYes. The mouth is in the center. If you zoom in on it, you can see that it is serrated.
Bugscope TeamThe red "+" near the word Magnification at the top should increase the magnifications.
- Bugscope Teamthe 'head' is a called a capitulum, and on the sides are palps that fold down when the center portion sticks into your skin
- Bugscope Teamback to the spider
- Bugscope Teamthe big sort of rectangular things are the chelicers, or chelicerae
- Bugscope Teamat their tips are the fangs, which point in toward the center
- Bugscope TeamIn other words, this is the part that would chomp on you if it were bigger. :)
- Bugscope Teamthere's a lot of 'fur' where the fangs are -- a lot of setae
- Bugscope Teamyou can change the magnification using the controls at the top of the screen
- TeacherMOVING TO THE INDIVIDULE COMPUTERS NOW
- Bugscope Teamsuper cool
- 8:44 am
- Bugscope Teamthe students can log in as students or as guests, not as teachers, and no password is required
- Bugscope Teamhere we can see another tick, and its eyespots, which are actually groups of pores
Bugscope TeamThe eyespots are just to the left of center and in the upper right of the head.
Bugscope TeamIn this image, that is.
- Bugscope TeamSHABLAZE! Awesome!
- Bugscope TeamShablaze welcome to Bugscope!
- Bugscope TeamWelcome!
- Bugscope Teamplease let us know when you have questions
- Studenthey scot
Bugscope TeamAustin! Sweet!
- Bugscope TeamLet us know if you want to drive the 'scope.
- 8:49 am
- Bugscope TeamNazhir Hello!
- Bugscope TeamBob welcome to Bugscope!
- Studenthey !
- Bugscope Teamhi!
- Studenthi austin
- Bugscope TeamMan, Scot gets all the attention around here......
- Studentthrow $5 bro
Bugscope TeamHi NatQ!
- Studentwasgood with it? I got 5!\
- Studentyall wildin
- Studentwhats up "ganjaking
- Bugscope Teamhello Everyone! Please let us know when you have questionss.
- Bugscope Teamss
- Bugscope Teamthis is the face of a female mosquito
- Studentwhere are the eyes
- Studentidk if it was a spider or not
- StudentHow can you tell the difference between a male and a female?
- Studentyday i saw a spider that could jump
Bugscope TeamJumping spiders really cool. Some of them around here have these huge black eyes.
- Studentwhy does it have soo many eyes?
Bugscope Teamthey help it see in as many directions as possible at one time. they also respond mopre quickly to changes in the visual field
- Studentwhat are the little bubles ?
- StudentWhat are those things coming out of his eyes? Are those his eyes?
Bugscope TeamThe eyes are the two C-shaped areas that look like they're made out of little pingpong balls.
- Studentdo all insects have hair on their eyeballs
Bugscope Teamnot all
- Studentwait are the eyes all those little dots ?
Bugscope Teamyes those are facets, or ommatidia, on the compound eye of the mosquito
- Studentwhat are the thing in between the eyes?
- Studentwhat are the little circles or dots around the eye
Bugscope Teamthe tiny dots are individual facets of the eyes, called ommatidia
- Studentwhy do they have hair on their eyes what does it do for them?
- 8:54 am
- Studentso they have multiple eyeballs
Bugscope TeamYes. They have ommatidia - basically a bunch of small little eyes that work together to make one big eye.
- Studentwhat purpose do mosquitoes besides sucking our blood?
Bugscope Teamthey serve as food for some things like birds and more helpful insects we would like to have around
- Studentso if one eye gets poked out does that affect the whole eye? or does it grow back? or what happens?
- Studentwhy do the antenna look look hair?
Bugscope TeamA lot of setae (the term we use instead of hair) are sensory. They help the insect sense the surroundings, and help it smell for chemicals in the air.
- Studentwhat is that cuticle looking thing to the right
Bugscope Teamthe shaft like thing is the proboscis, which has a fascicle in it with the bitimg parts
- Studentdo you have pictures of scorpions or nah
Bugscope TeamNot today. We've had scorpions here before.
- Bugscope Teamthe life span of an insect is so short that things usually do not grow back.
- Studentsince it has so many eyes does it see many of the same image?
Bugscope Teamit processes what it sees so that is makes sense -- just like our eyes, which would normally see everything upside down, but obviously don't
- Studentwhat are the things between the eyes? the 2 circles with the things sticking out
- StudentWhat are under the eyes and what is sticking out of them?
Bugscope Teamthere are palps, which help smell/taste
- Studentmosquitoes are wack. show us something else
- Bugscope Teamif something has a much longer life span, like a tarantula, or they can still go on to the next part of their life cycle, like a caterpillar to a butterfly, then it will grow things back
- Studentohh thats cool, do you get paid alot for this job?
Bugscope Teamyes and it is super fun
- Studentwhats this
- StudentWhat are mandibles
Bugscope Teamthe same thing as jaws
- Studentdo plier ants eat wood?
- Studentso if one eye gets poked out does that affect the whole eye? or does it grow back? or what happens?
Bugscope Teamnothing is going to grow back
Bugscope TeamOnce damaged, it is permanently damaged. Unless it molts, as Cate said. Not unlike us. You poke your eye out, it is gone.
- StudentWhat's this?
Bugscope Teamthese are the jaws of a plier ant
- Studentor at a college?
- Studentwhat are the things that are sticking off
- Studenthow much do u get paid
- Bugscope TeamScott just changed the mag.
- Studentis this in a lab?
Bugscope Teamyes we run a microscopy suite that has lots of high-end microscopes like this one in it
- Bugscope Teamnow you can see the base of one of the antennae
- 8:59 am
- StudentDo ants have more than one mandible
Bugscope TeamYes, there are two. They are modified legs that are used to tear and crush food.
- StudentAre those its teeth?
Bugscope Teamthey look like teeth and serve that function but are not technically teeth
- StudentWhat are those hair-like things?
- Studentok next pic
- Studentare they dead
Bugscope Teamyes all the things you see today are dead. they are in a vacuum and have to be dry in order to image them
- Studentwat is this
Bugscope Teamthis is a small ant that feeds on Collembola, which are also called springtails
- Studentscot you didn't answer my question bro
Bugscope Teamsorry I missed it DaddyO
- Studentare the jaws like super strong and indestructable
Bugscope Teamto some extent, but not perfect
- Student*inserts laughing emogi* x10
- Studentscot youre funny
- Studenti like funny
Bugscope Teamsuper cool
- Studenthow old are you?
- Studentis this basically a maggot
Bugscope Teamhaha Yeah in a way -- it is a larval insect
- StudentSo they eat and walk at the same time
Bugscope TeamWell, possibly. The mandibles are structurally similar to legs. I suppose they could eat and walk, but Josh would have to answer that since he's Antman.
Bugscope TeamWell, not walk on the mandibles. But walk and chew gum at the same time.
- Studentfavorite for a retweet
- Studentis it scott? or scot?
Bugscope TeamScott but Scot for Bugscope
- Studentare thoes the eyes sticking out
- Studentcan we know more about u
- Studentwhere r u from nationality
Bugscope Teamhorrid place now,. embarrassing
- Studentso what is the thing inbetween those 2
Bugscope Teamreally not sure
- Studentwho cares...tell me your country
- Studentis it detroit
Bugscope Teamno I was born in Kansas City
- StudentAre larva the same as catapillers
Bugscope Teamcaterpillars are the larval stage
- Studenthow old are you guy?
Bugscope TeamI am like super old you woudn't believe.
- 9:05 am
- Studentwhat's in the middle of the palps
Bugscope TeamTo be honest, neither Scott nor I know what that was. It is another mouthpart, but as to its function, we're not sure. Since we're not there any longer, Josh can't give us insight.
- Studentdo you have any kids?
Bugscope Teamnot that I know of and pretty sure I don't
- Studentwhat is super old bro?
- Studentis it deflated bc it has no food supply currently?
- Studentscot your funny broski
Bugscope TeamThanks KingGanja.
- Studentwhere are its eyes?
- Studentwhat is your job description
Bugscope TeamIt used to be Senior Research Engineer. I kind of liked that.
- Studenthow long do ticks live
Bugscope TeamAccording to the CDC, some ticks that carry Lyme disease can live up to three years. Our tick expert, T.J. isn't here today to let us know if they live longer than that.
- Studenti fxcks with you scot
Bugscope Teamno thang DaddyO
- Studentdo each of you specialize inn different insects?
- Studentdaniel are you a girl or boy
Bugscope Teamdaniel is a boy
Bugscope TeamCorretion, Cate. I am a man, a dude, and an all-around professional bada.... hahahaha
- Studenthow do ticks digest blood
Bugscope Teamprobably enzymes inside; they carry a lot of bacteria as well, that could help
- Studenti fxxcks with you too daniel
- Studentyooo yall gotta chilllll
- Studentthis ya job right here , this shxt cool as***
- Studentare you guys all together?
Bugscope Teamwe can connect in the same space, around the microscope, or from different places, like Cate is probably in her ofice
- Studenthow do ticks move around after drinking a lot of blood
- Studenthow do ticks react to certain blood types
Bugscope TeamI don't think they discriminate that way
- Studentwhat purpose do ticks have besides giving Lyme disease
Bugscope Teamthey are food for other animals
- Studenthow would you kill a tick
Bugscope TeamYou have to be careful when taking it off your skin that some of its mouthparts don't get embedded in the skin. The best way to do that is to try to make it leave on its own. Cover it with petroleum jelly or oil so it can't breathe, or use a flame from a lighter or a match. Once they back out, you can pick them off with tweezers and smash them with a hammer. :)
- Studentcan they pee?
Bugscope Teamusually they control water loss carefully, but yes they can pee
- Studenthave you ever met?
Bugscope Teamyou mean the other Bugscope people? yeah
- 9:10 am
- Student@brittbrat dead
- Studentcan yall change thee bug or...
Bugscope Teamyeah sorry
Bugscope TeamThe Mrs. Prince account can choose presets, or Scott can drive for you.
Bugscope TeamOr we can pass control to to someone.
- Studentscot don't gas
- Studenthow do you know if you have ticks in or on you?
Bugscope Teamyou could feel them as big bumps stuck to you
- Studentso if you just pulled a tick off of a dog (for example) with out suffocating it, would the mouth still be in the body of the dog?
Bugscope TeamPossibly. And that increases the risk of getting disease from the tick. The mouthparts are made of chitin, which is a stiff material like your fingernails. But it breaks easily.
- StudentI'm guessing we are looking at the underside
Bugscope Teamyes almost always 'cause it is more interesting
- Studentwhat is the lifespan for a tick
Bugscope TeamIt can be up to 3 years that I know of.
- Studenthow is this considered a larva if it has a mandibles and legs?
- Studentwhich ticks carry limes disease
- Studentwould you feel it if they bit you?
Bugscope Teamthey don't hurt and you might not feel it
- Studentnext bug bro
- Studentwhats the back part of the larva called( and the front)
- Studenthow often do they reproduce
Bugscope TeamI think in season within a few months, kind of a copout answer
- Studentwell can you call tanya
Bugscope TeamDude she is in Portland OR right now
- Studentthis is mrs. prince, i know that mosquitos prefer type 0 blood, is there something like that for other bugs?
Bugscope TeamNot that I'm aware of. I do know that most insects have very specific food requirements. E.g. caterpillars will only feed from particular species of plants.
Bugscope TeamThat is, I'm not sure if other blood-sucking arthropods have that specific of a preference.
- Bugscope Teamthere is a big entomology conference there right now
- Studentwhere can these be found?
Bugscope TeamJiggyBoy I am not sure what this is -- some kind of aquatic insect larva from Vermont.
- Studentdo u play football
- Studentdo you skate?
- Studentwhat is a larva
Bugscope Teamit's like what the caterpillar stage is, before the insect becomes an adult
- Studentor lax?
- Studento ighh
- Studentwhich ticks carry limes disease
Bugscope Teamnot sure -- some more than others; Tanya is not here and she would know right off.
Bugscope TeamThe CDC says deer ticks, lonestar ticks, and dog ticks.
- Studentis that true
- Studenthow fast do they suck the blood?
Bugscope TeamTicks take their time. The females can get quite bloated over the period of several days if not removed.
- Studentdo u play hockey baseball
Bugscope Teamnow I do this kind of crossfit thing and also Pilates
- 9:15 am
- Studenttf is that!?
- Studentwait dont change
- Studentif this is the baby phase what is the adult version of this called
Bugscope Teamsome kind of fly, like a mayfly or a stonefly but I am sorry I am not sure what that was
- Studentwhats the things that look like butt cheeks
Bugscope Teamhaha Those are the compound eyes!
- Studentif both of their eyes have a million more how do they see well
- Studentdo u surf
Bugscope Teamnot very well
Bugscope Teamnot much surfing goes on in central illinois
- Studentare those all eyes?
Bugscope Teamyes they are -- thousands of individual lenses
- StudentWhats that thing sticking out at the top?
Bugscope Teamthose are the antennae
- Studenti heard that once animals get high , they stay high until they die
Bugscope TeamI don't know what happens to animals if they get high on what your login handle suggests. But I do know that dogs cannot handle caffeine or theobromine (the active ingredient in chocolate). They cannot metabolize it, so they go into this hyperactive state until renal failure (kidney failure) sets in and they have a heart attack. Never feed a dog (or cat) chocolate - especially dark chocolate - or coffee. Or Red Bull.
- Studentso do we move slow to them?
- Studentwhy do they like swarm around things like dead bodies and feces
Bugscope Teamstuff for them to eat
- Studentlooks like bubble rap
- Studentwho do they eat poop
Bugscope TeamFor the same reason we eat food. There are nutrients in the poop that nourish the fly.
Bugscope Teaminsects are very resourceful
Bugscope TeamThey don't always eat poop. The larva also feed on decaying meat and vegetable matter.
- Studenthow do they reproduce
Bugscope Teamall different ways, some are parthenogenic as well, meaning they do not need mates
- Studentthanks daniel
Bugscope TeamNo problem, man!
- StudentOur session time will be ending in about 5 minutes
- Studentif one of the eyes are poked out can they still see
- Studentdo you have hornets
- Studentwhat are the things that look like mesh
- Studentwhats an ommatidium
- 9:20 am
- Studentdo they have depth perception>
Bugscope Teamyes! good that they have two eyes, giving them that stereo advantage. good questions
- Studentdo you have dragonflies
Bugscope TeamNot on the stub today, but we've had dragonfly parts. The whole dragonfly is too big for our scope. I did accidentally have a dragonfly nymph in my aquarium full of tadpoles. By the following week, I had one big nymph and no tadpoles. I was sad. :(
- Studentwhy do they only have a lifespan of a day?
Bugscope Teamsome insects do as adults; like all they need to do as adults is breed and die, not even eat
- StudentWhat's that web like thing?
Bugscope TeamThat is most likely fungus. This mosquito has probably started to decay somewhat.
- Studentwhats the tissue inbetwen the eyes
Bugscope Teamit's a biofilm, with bacteria in it
- Studentdon't be sad daniel
Bugscope Teamhahahaha. I think I'm over it. But it left scars, man! It left scars!
Bugscope Teamhe'll be alright; he's a trouper
- Studenti feel you dawg
- Studenthow long does it take for dead things to decay
Bugscope Teamdepends on heat, humidity, what gets there first
- Studentwhen they are larvae why are they underwater
Bugscope Teamthat is where the eggs are laid
- Studentjosh wya yo
- Studentso do we move slow to them or no?
Bugscope Teamyes exactically we move at about the speed of rocks to them
- Bugscope Teami'm not sure what happened to josh
- Studentwhat is the role of mosquitos in nature
- Studentcan mosquitos breathe underwater
Bugscope Teamwhen they are larvae they do, but not as adults
- Studentyou have to have ladybugs bro
- Bugscope Teamthis is completely awesome
- Studentdo you have ladybugs
Bugscope Teami do in my house.
Bugscope Teambut not on the stub today
- Bugscope Teamsee the two super sharp things?
- Bugscope TeamDaniel says mosquito larvae have breathing tubes and thus I am wrong
Bugscope TeamOh, Scot, oh scot. Wherefore art thou Scot?
- Studentdo you havw atwe4rbugs
- StudentThanks, adios
- Studentthank you
- Studentthanksfor your time broski!
- StudentThank You!!!!
- 9:25 am
- Studentthank you
- Studentbye bros
- StudentThanks for answering my questions
- Studentare we your facvorite class?
Bugscope Teamyes for sure
Bugscope TeamYou are our favorite class from New Jersey on a Wednesday morning in mid-November 2014! ;) (Yes, you're a great class.)
- Bugscope Teamthanks and thanks Ganjaking
- Studentthank you! :)
- Studentcate is my favorite
Bugscope TeamCate made today's sample, DaddyO.
- Studentlmk if you still want to throw 5
- Bugscope TeamThank you, Everyone!
- Bugscope TeamIt's too bad Tdot isn't here. She could have done her tick rap.
- Bugscope Teamthanks PJ
- StudentScott and Daniel were my favorite! Cate you seem cool too!
Bugscope TeamCate is cool.
- Bugscope TeamCate is a reformed physics student, like an ubernerd.
- Bugscope TeamMrs. Prince, when does the next class login? And should we clear out the student names for you?
- 9:31 am
- Teacherwe have our lunch times now until 11:33 - i will introduce bugscope, and the kids will log in at around 11:45, please clear the names, and i will tell them to use their first names.
- Bugscope Teamwe're fine with the hiphop names; we'll clear them now...
- Bugscope TeamThank you, Mrs Prince!
- Teacheryeah but if they use their real names i can tell who is asking the inapprop stuff
Bugscope Teamall good
- Bugscope Teamhttps://bugscope.beckman.illinois.edu/members/2014-079
- Bugscope Teamwe anonymize the names on the transcript, except in the text itself
- 9:39 am
- Bugscope TeamJoseph are you online now?
- Bugscope TeamMacDaddy?
- Bugscope TeamL4L and Purp, Zaab?
- Bugscope TeamBebe!
- 9:54 am
- Bugscope TeamYay! Yuanxi!
- Bugscope TeamThe next class is due at 10:33 our time.
- 9:59 am
- GuestHave to leave 10:50 am to my class. Sorry.
- Bugscope Teamnice to see you, though
- GuestFrom the transcripts, can tell you had a great time.
- Bugscope Teamthank you for logging in
- Bugscope TeamDaniel is doing some computer stuff.
- Bugscope TeamCate and Josh I am not sure about.
- GuestHave a great time there. Will stay till 10:50.. get a few glance of the pictures. Are you going to change the sample for the next session?
- Bugscope TeamI'm looking for more stuff for them to see. It will be a different group, so the things I found early this morning will not be old to them.
- 10:08 am
- Teachercan i get a transcript
Bugscope Teamit's being collected now...
Bugscope TeamThe transcript is collected as we type, and will be completely available online at the end of the session. We anonymize the names because of privacy issues we encountered previously with stalkers. (Seriously.)
Bugscope TeamMrs. Prince, I will try to save a copy of the entire transcript as seen in my browser and forward a copy to you. It won't look great, but you will be able to open it in a web browser, and follow (from the bottom, up) the progress of the chat session. I will do this at the end of the session and it should include everything, barring web browser crashes or mistakes on my part. I have already saved the first part for you.
- 10:28 am
- Teacherhi, i definetly want to do the eyeballs, the female mosq, the tic
- Bugscope Teamsuper cool
- 10:34 am
- Teacheralso... can you guys focus more on how this will be used in forensics? such as identifying the type of bug that decomposes the body and using that as a time of death (age of dead body)? thanks
- StudentDo ants have saliva ?
Bugscope Teamgood question -- I think so...
Bugscope TeamYes, ants do have saliva, but it is fairly primitive in the adults and lacks many important digestive enzymes. Adult ants primarily rely on their larvae to digest their food for them and then the larvae regurgitate the partially digested food back to them. Their mandibles are used almost exclusively for handling brood and foraging for food and cannot function as chewing mouth parts. The "teeth" on the mandibles that the students asked about are used in prey capture. Like swinging a two by four with nails.
- Teacherabout the tic... it is cool that the eyes are on the back, if you think about how the tick situates on the dog's body, eyeballs in the front would see only fur, they need an eyeball on the back of the body.
Bugscope Teamthey cannot see like we do; we think the eyespots are actually heat sensing
Bugscope Teamthe Haller's Organ, on the edge of the forelimbs, can sense CO2 and maybe some other things like water vapor from your breath
Bugscope TeamLoss of eyesight is fairly common in parasites. Parasites tend to have reduced sensory function because once they find thei host, they typically do not need to respond much to external stimuli like visual light, because they are well protected on or in their host.
- 10:41 am
- Bugscope TeamMrs Prince are the kids' names on the righthand screen now ones we should delete?
- Bugscope TeamIf you or your students have any questions please feel free to ask :)
- Teacherthose are not my kids
- Teacherwe are not in the library yet
- 10:46 am
- Bugscope Teamthese are the parts of the mosquito that stick into your skin
- Bugscope Teamthis is one of the two ticks on today's stub
- GuestOff to class..Kill my log in at your convenience. Nice to see everyone here!
Bugscope TeamThank you, Yuanxi!
- Bugscope Teamto the far left we can see one of the organs the tick uses to sense its prey
- Teacherhi scott, my class is ready to start
- Bugscope Teamawesome!
- Bugscope Teamwe're looking right into the mouth of a tick
- 10:51 am
- Bugscope Teamthe 'head' of a tick is called the capitulum
- Bugscope Teamthe center portion of the capitulum is called the hypostome; it sticks under your skin
- Teacherwhat kind of tic is this?
Bugscope Teamit may be a Lonestar tick, I am sorry I am not sure
Bugscope TeamOur tick person is in Portland atm. It is a hard tick, a member of the family Ixodidae, but beyond that I couldn't tell you which species. I normally use color patterns to ID them, which you cant see through an SEM
Bugscope TeamA lone star tick would have a white star looking marking on its dorsal side (the side we can't see in its current position)
- Teacheris that a tongue?
Bugscope Teamthat is the barbed part that holds the head fast into your skin
Bugscope Teamthe tongue uis kind of broken up; it is a rasper, like a file that cuts into your skin so it breathes
- Bugscope Teamthis is what I consider the tongue
- Bugscope Teamticks go from a juvenile stage with 6 legs to an adult stage with 8 legs
- Bugscope Teamoften we can see bacteria on the outside of their bodies -- on the cuticle
- Bugscope Teamwe know that ticks can repair their bodies when they break or burst open
- 10:56 am
- Teachermoving to the libary now
Bugscope Teamsee you soon!
- Bugscope TeamDifferent species of ticks can transmit different disease to humans, including Rocky Mountain Spotted Fever and Lyme disease.
- Bugscope TeamSome species also have toxic saliva that paralyze their hosts as they feed.
- 11:02 am
- Bugscope Teammaybe you are thinking about bees?
- StudentIs it true that when Mosquito's bite you, they die right after?
Bugscope Teamno not at all
Bugscope TeamThe mosquito only dies if you squash it
Bugscope Teamonly females will bite you. they need the blood meal to lay eggs
Bugscope TeamCertain mosquitoes can lay multiple sets of eggs and will bite before they lay each set.
- Studentwud up tim
- Bugscope Teamthis is a male mosquito. you can tell, with your eyes, that they are males because they have these really ornate antennae, whereas those of females are not that fancy
- Bugscope Teamthe male mosquito has a proboscis but does not bite
Bugscope TeamMales feed primarily on nectar from flowers
- Studenthey guys
- Studentwhat do males do then
Bugscope Teamthey breed and die; they are said to live on nectar, like from flowers
Bugscope TeamMale mosquitoes find female mosquitoes by sensing the vibrations that the female mosquitoes' wings make
Bugscope TeamMales have very plumose antennae that are very sensitive to airborne vibrations.
Bugscope Teammales have specialized organs on those ornate wings that help them zero in on the wingbeats produced by the females' wings
- StudentHow do they eat?
- StudentFemale Mosquito's head look different?
Bugscope TeamThey have less plumose antennae
Bugscope Teamyes they do -- the first big difference is in the antennae
- 11:07 am
- Bugscope TeamMoving to the eye of a different mosquito. The one you were on was not in good shape.
- Studenthow do they get rid of waste?
Bugscope TeamHow do you think...
- StudentMrs. P here, show them the eyeball.
Bugscope Teamhere is the female mosquito, where we can see the compound eyes much better
Bugscope TeamI'll zoom in on the ommatidia, if that is OK.
- Studentwhat do you eat
Bugscope TeamCheeseburgers mostly. some pizza here and there...
- Studentmrs p here can you delete the old convers
- StudentWhat is an ommatidium?
- Studentwow thats interesting
- Studenthow do mosquitoes have sexual intercourse
Bugscope TeamI'm not sure if they do it in the air, like some flies do, but basically I believe they connect the tips of their abdomens.
Bugscope TeamSome mosquitoes match their wing vibrations in a precopulatory courtship ritual. So if your a male mosquito looking to get laid, you gotta be able to harmonize
- Studentwhat is their favorite food?
- Studentwhat you got me lookin at
- StudentDo you get paid for this?
Bugscope TeamYeah. In sunshine and rainbows. Via direct deposit.
- Studentare those scales
Bugscope Teamthose are fine features on one of the compound eyes
Bugscope Teamwe think they help focus the light into the receptors beneath
- Studenttrhe bugs are dead right
- Studentzoom out
- Studentso do you yourself kill them or do you recieve them dead
Bugscope Teamsometimes we have to stick them in the freezer for a while to kill them. usually we receive them already dead
- Studentwhats an ommatidium
- Studentcan we change this pic
- 11:12 am
- StudentDo you do this everyday for students around the country?
Bugscope TeamTwice a week
Bugscope TeamThe class can be from anywhere in the world I believe. My first session was with a group from India
Bugscope TeamWe try to schedule two a week. The scope is used by people engaged in doctoral or postdoctoral research, so that occupies the bulk of its time
Bugscope TeamI did a survey of the data, and we have now had students from every continent except Antarctica.
- Bugscope TeamAsiaJ26 I gave you control of the 'scope.
- Studentwhat attracks them to blood?
Bugscope Teamthey can sense heat from our bodies and also CO2 when we breathe
- Bugscope Teamthis is cool
- Studentms p here how bout a diff bug
Bugscope TeamWasp wing hamuli. Not in very good shape though.
- Studentmy control not working
- Bugscope Teamthe hooks we see connect the fore and hindwings on a bee
- Studentasiaj6 stop playing girl and pick a picture
- Studentok nvm we got it
- Studentwhy would you want to kill bugs, they are apart of nature
Bugscope TeamBecause they are so small it is very difficult to examine morphological features without taking them into the lab and observing them under a microscope like this one. In order to do that we have to kill them. It doesn't affect the environment much though because most insects are short lived and there are just so many. The weight of all spiders in Great Britian outweighs the weight of all people living there.
- Studentthanks man
- Studenti mean josh
- Bugscope Teamthis is one of the ommatidia, and we can see that it has bacteria on it that are starting to make it break down -- to decompose
- Studentim back boyy
- Bugscope TeamZooming in on some fungus.
- Bugscope TeamScott will tweak the picture quality.
- Studentis this a rare bug?
Bugscope TeamNope. It's a common mosquito.
Bugscope TeamNow we are looking at some pollen from a plant.
- StudentSo uh.. do you get paid for this?
Bugscope Teamwe get paid to train people to use the microscope to do their research
- StudentWHY ARENT YOU RESPONDING TO US?
- Bugscope Teamactually about 30 microscopes of various types
- Studentwe dont want control anymore
Bugscope TeamI can take over if you want. But if someone else wants to drive, that's the best way to explore on your own.
- StudentDo you guys have rare bugs?
Bugscope TeamAt the Insect collection on campus yes. the insects we use for these sessions though have to be thrown away eventually so we tend to only use common ones that are easily encountered
- 11:17 am
- Studentmary eat my butt
- Student@ ME
- Studenthow you gonna dip on my class
- Bugscope Teamsometimes we look at rare insects that someone is describing as part of a key to that particular new species
- StudentNo hard feelings but uhh.. why aren't you answering my question? :(
Bugscope TeamThis is all volunteer.
Bugscope Teamsorry missed your question...
- StudentIs it true that Mosquito's don't like hairy body parts, or Lavender perfume?
Bugscope TeamHair makes it difficult for a mosquito to land and reach the skin. So it wont stop them from trying but it will slow them down. Thats why humans make such good hosts because we are relatively hairless and very commonly encountered. Not sure about Lavender perfume.
- StudentWhat are those spikes
Bugscope Teami think they help the pollen grains stick to things, like fur
- Teacherthe ball with spikes looks like a virus
- Bugscope TeamRounak you asked if we get paid for this. Yes we do. This is only a small, fun part of our jobs.
- StudentDo you guys have caterpillars?
Bugscope TeamNot today.
- Studentis this pollen from off the trees
Bugscope Teamwe think it is from grass, not sure
- StudentOr lady bugs?
Bugscope Teamnot today
- Studentso do you only get paid if you're an entomologist?
Bugscope TeamCate and I are microscopists.
Bugscope TeamI am an entomology graduate student. I get paid to go to school atm. But yes, professional entomologists do get paid.
- Bugscope Teamthis is what the sample looks like inside the microscope
Bugscope TeamWe have a few ants!! :)
- Bugscope Teamthe microscope is about 4 or 5 feet tall and like a very large desk
Bugscope TeamHey, ants are cool....
- Teacherhow large, i mean like, tall is your microscope
Bugscope Teamthe main component is about the size of a fridge box
- Teachercan they see the female mosq or the manibular jaw thing?
Bugscope Teamyou bet
- StudentWhat about preying mantuses? (i can't spell) :(
Bugscope TeamNope. The most common species around here probably takes up too much room to be used in this scope as adults.
- 11:22 am
- Teacherdo you ever examine the bug commonly called the "stink" bug?
Bugscope Teamyes we do!
Bugscope TeamStink bugs are an entire family of insects, and yes we do occassionaly
- Studentwow that looks like a sea creature
- Teacherwhat are the tab like things and what are the hair like things?
- Bugscope Teamthese are the mandibles and you can also see a bit of the palps of a small ant called a plier ant
- Studentwhat is a mandible?
- Teachermandible is a jaw guys
- Studentwht is this ???
Bugscope TeamThe mandibles of the ant Strumigenys rostrata. they are specialists on small fast jumping insects called springtails
Bugscope TeamThe teeth on the inside of the mandibles are used to get a firm grip on the springtails they capture so that they cannot jump away before the ant stings them
- Teacherwhy don't you ask a lot of REAL DEcent questions and see how fast josh can respond
- StudentJosh is so slow. :D
Bugscope Teamhe is typing larger chunks of info
Bugscope TeamAnd I make loads of typos my OCD forces me to correct :/
- StudentANT JAW
- Bugscope Teamin people the upper jaw is called a maxilla, and the lower jaw is called the mandible
- Teacheri will accept an apology now
- Studentwhat is this?
Bugscope Teamwe're looking at the mouthparts of a tiny ant
- Studentthis is getting outta hand
- StudentYeah what is this
Bugscope TeamThe mandibles of the plier ant Strumigenys rostrata. you guys are zooming out on the rest of the ants head. It is heart shaped because it has enlarged mandibular closer muscles, allowing to have a stronger mandible grip and to close its mandibles extremely fast so it can catch springtaisl
- 11:27 am
- Bugscope Teamhere is the whole head
- Bugscope Teamnow we see where an antenna fits into the ant head
Bugscope TeamThese ants are very cryptic and like to play dead when disturbed, so having retractible antennae helps them do that. they also retract their antennae when they strike with their mandibles, so that they dont accidentally bite themselves
- Bugscope Teamfrom the micron bar on the lower left we can see that the head is less than a half millimeter wide
- StudentCan the ant funtion without its antennas?
Bugscope Teamnot for long; it needs to be able to sense chemical signals, and the antennae do that
- TeacherHey scott, can others write in, beside my perfect students - that is
Bugscope Teamyes they can, and we can remove them, as Cate did to the person who was particularly bad
Bugscope TeamYes, because we frequently have other teachers from other schools observing (though not today). When guests or students become abusive, we can remove them from the list.
Bugscope TeamI had considered kicking off Unknown earlier, but since they were colored blue, thought they might be a legit student.
- StudentWHERE IS THIS FOUND ?
Bugscope TeamMy labmates collected a colony of this species very close to campus in Urbana Illinois.
Bugscope TeamOther species of Strumigenys can befound throughout the US. the most diversity in this country is in the southeast in the carolinas and georgia.
Bugscope TeamThe genus is found globally though. there are at least 835 known species
- StudentIs this deadly?
Bugscope TeamNot unless youre a springtail ;)
Bugscope Teamthe ant is only about 3 mm long. Strumigenys are pretty tiny ants.
Bugscope TeamThey do have stingers but I doubt theyre big enough to puncture human skin. Plus when theyre handled they freeze so they probably wouldnt even try to sting you anyways
- Studentwhat is that
Bugscope TeamA plier ant worker, Strumigenys rostrata.
- Bugscope Teamthere are body farms in various places in the U.S. where cadavers are studied to determine which decomposers colonize them, and in what order
- 11:33 am
- Studentso how can you get a job doing this? what would you have to do?
- Teacherin forensics - like in autopsies, how can the microscp be used to establish time of death?
Bugscope Teampeople have mapped out which insects, often types of flies, will colonize a corpse, and in which order.
Bugscope Teamso the person performing the autopsy can check to see which insects have laid their eggs in the cadaver, and what stage the larvae are in
Bugscope TeamMicroscopes in general can be used to identify the species of insect, which may provide clues to where the evidence was located aside from the scene of a crime.
Bugscope TeamThis is also true for non-insect specimens. E.g. pollen can be an indicator of not only location but time of year. It does not degrade easily, and while it cannot usually be identified to a particular species, it can often be associated with a particular genus. Once this is known, most plants in temperate regions have a small window of time in which they shed pollen - usually on the order of days to perhaps a few weeks.
- StudentWhy it look hairy
Bugscope TeamIt uses the hairs for sensory information. some hairs are mechanoreceptors for touch, others are chemoreceptors for smell. Strumigenys tend to have very bizzarre looking hairs on their body, the function of which is currently unknown but something I plan on studying during my PhD work
- Teachercaddisfly laravae looks cool, can you show it and tell the kids what larvae is?
Bugscope TeamHere it is. A larva is the caterpillar form of an insect, if it has one. It then metamophoses into a flying insect, in many cases.
- GuestFOH IM BACK
- Teacherorient us, what's the mouth, eyes etc.
Bugscope Teamthe mandibles are small, and we do not see the eyes, which are often tiny and look like little bumps
- StudentWhat did you all major in, to become professionals?
Bugscope TeamI was an Entomology major as an undergrad. Im currently majoring in Entomology for my masters/PhD
Bugscope TeamI was originally a computer scientist. I got involved in this because I was a programmer and visualization consultant at the Beckman Institute when we initiated the project. I designed the first web site in 1999, and then later rewrote a lot of the software. I then went off to work on a Ph.D. in Horticulture (plant genetics), and having recently finished that, am looking for a job.
- Teacherplease drop Anon student
- Studentdemetria :)
- Teacherdrop peter griffin
- Studentand peter
- Bugscope Teamthe things that are sticking up are palps, which are used to taste and sometimes help move food toward the mouth
- StudentHave you guys handled Tarantulas before?
Bugscope TeamFor the scope? probably not, as they are large, relatively long lived, and expensive
Bugscope TeamI do have a pet rose hair tarantula right now though! her name is MaryJane :)
- Studentwhat are those sticks
Bugscope TeamOn the head of the caddisfly larvae? those are hairs, or setae.
- Bugscope Teamwe have looked at parts of tarantulas; they have what are alled urticating hairs that they can release and which can stick into your eyes
- Studentwhy you name it maryjane?
Bugscope TeamSpider-man's wife is named MaryJane. and It sounded cute :)
- Studentyea ok
- Teacherand the thing in the the middle medical term - penile in appearance
- 11:38 am
- Studentpeace bruh class about to end
- Teacherwhat are the 2 protruding things?
Bugscope TeamThey are probably palps- either labial or maxillary. They help the insect taste and manipulate food
- Studentwe out
- Studentare those eyes
Bugscope TeamI don't think we can see the eyes, if there are any.
Bugscope Teami dont see the eyes, but they would be on the very sides of the head if they are there
- Studentgoodbye fuckboys
- StudentBYE :D
- StudentWhat's the difference between centipedes and millipedes? Centipedes have 10 legs right?
Bugscope TeamCentipedes tend to have less legs, but the number varies between species. centipedes have one pair of legs per body segment where milipedes have two pairs per segment. Centipedes are carnivorous while milipedees are all detritivores and eat decaying organic matter
- Bugscope TeamBye you all! Thank you for connecting with us today!
- Bugscope TeamBye! thanks for listening! :) hope you had fun!
- Studenti like this its dope , you learn alot
Bugscope TeamThank you, Q!
- StudentBye! Thanks guys :)
Bugscope TeamThank you, Rounak!
- 11:44 am
- Bugscope Teamwe're going to shut down soon...
- 11:51 am
- Teacherthank guys
- Teacherwow, that was a lot of inapprop stuff - how do you feel about that?
- Bugscope Teamno problems with us
- 11:56 am
- Bugscope Teamwe like working with kids, and we are used to them acting up sometimes
- Bugscope Teamfor us the best things to do are answer the kids who are interested, so we don't shut them out just because someone else is being a bad egg
- Bugscope Teamsometimes it's the smart kids who act out, and they figure out pretty quickly that if they want a response they can ask good questions
- 12:01 pm
- Bugscope Teambye!
