- Studentso, do you know what specimen this is?
Bugscope Teamthis is the head of a male mosquito
- Studentthat is a cool picture
Bugscope Teamawsomes I just gave you control of the 'scope
- Studentthis is the head of a male mosquitoe
- Studentso does SEM stand for scanning electron microscope??
Bugscope Teamyes that is right!
- StudentWhat are facets?
Bugscope Teamthey are the individual components of the eye. Facets are also like the different sides to a diamond
- Studenthello scot!
- Studentcool masqueto head
- Bugscope Teamwelcome to Bugscope!
- Bugscope Teamsomeone needs to drive
- Studentthank you

- Studenty is it moving
- Studentand what is that a picture of what bug??
Bugscope Teamthis is the head of a spider; you can see the eyes
- Studentthats cool!
- Studenti dont no
- Studenthow many insects have been discovered?
Bugscope Teamhundreds of thousands, and there are still more
- Studenthow do u get a pic of a spider head?
- Studenthey when was the microscope invented
Bugscope Teamthe electron microscope was invented in about 1931
- Studentwhat is the stuff on the head
Bugscope Teamthere are bug hairs on it around this sphere/eye. Those are called setae (see-tee)
- Studentwhat are the hairs coming off of it?
- Studentwhat exactly do you do at your job?
- Studenthow big is the brain
- Studentcan i take control
- Studentwhat type of bugs are we going to learn about?
- StudentWhat Type of Spider is this
Bugscope Teamsorry we are often not sure at all about spiders
- Studentwhat is your favorite thing about science?
- Studentwhy is there only spider heads?
- Studentwhy do spiders have multiple eyes?
Bugscope Teamthe ocelli are good at seeing movement, but not at actually getting a very clear picture of things
- StudentWho has the control over the microscope
- Studentwho has control? because this is really complicated!!!
Bugscope Teamdude you can do it
- Student im super confused!!!!!!!!!!!!!!
- Studenthow many specinens
Bugscope Teamthere are 12 or 15 specimens today
- Studentwhy does it look rinkly
- 3:18 pm
- Studentwhat are all of your names?
- Studentthat is a really cool looking bug! :)
- Studenthow long does it take for the specinens to get damageed
Bugscope Teamyou mean by the electron beam? they will dry and fall apart before the beam hurts them badly
- Studenty do the legs looks like a stike
- Studentwhy do some spiders have lots of hairs & others dont have any?
- Studentthanks for the reply
- Studenthow big is a spiders brain?
- StudentAre the other 4 legs on the spider ripped off?
Bugscope TeamCate probably took a few legs off so she could get the spider to mount flat on the stub today
- Studentgoing off bye
Bugscope TeamPeace out
- Studentwho is evil oreos people
- Studentwhy is it so blury?
Bugscope Teamsomeone who is driving needs to focus
- Studentapproximately how many bugs do you look at under the scope in 1 day?
- Studentput ms.chin in charge please.
Bugscope TeamMs Chin is now the supreme ruler
- Studenthow do the eat?
Bugscope Teamthey inject their prey with venom that liquifies the prey's inside, then the spider drinks the insides like a milkshake
- TeacherI think we are going to have students shut their laptops so we can all focus on one screen and more questions
- Studentbye scot and cate
Bugscope TeamBye! Thank You!
- Studentwhat type of spider is that?
Bugscope Teamwe are not sure what kind it is, sorry
- Bugscope Teamthis is the butterfly claw
- Bugscope Teamit is pretty interesting for a butterfly
- Bugscope Teamyou can see one of the two curved claw elements to the left
- TeacherWhy do butterflies have claws?
Bugscope Teampretty much the same reason we have hands -- to grasp and hold things
- GuestHi students in Alaska - this is a teacher in California (yes it is warm here today). I hear you are studying about characteristics of insects. What kinds of features do you see here today?
- 3:24 pm
- Bugscope TeamMichele I'm not sure the students are using their laptops anymore.
- Bugscope Teambe sure and try some of the other presets. the more you go to, the more will show up in your database at the end of the session so you will have them to look at later
- TeacherHi, they shut their laptops down but are anwering the quesions here. They would like to know what the hair like strand is near the claw
- Bugscope Teamwell this right here is a mite on the spider
- Bugscope Teamthose hairs are called setae, and they are often sensory -- they feel touch but also, sometimes they smell and sometimes they sense hot/cold
- Bugscope Teamyeah I moved to that, sorry
- Bugscope Team'cause I love mites
- Bugscope Teambut I can put us back
- TeacherWe just talked about mites living off of other artropods yesterday.
- GuestHi Ms. Chin - I like their questions :)
- Bugscope Teamsome butterflies can smell with their feet, and the setae we see help them to that
- Bugscope Teamthe things streaming down like hair are actually hairs, bug hairs called setae
- Bugscope Teamwhen a Monarch lands on a flower, it scrapes the surface with bristles on its feet, and the scent that arises from that scrape is sensed but some of the chemosensory setae that are also on the feet
- Bugscope Teamoften there is also a pad called a pulvillus or an arolium that helps the insect stick to a surface; claws are not always helpful when an insect wants to stick to something
- 3:29 pm
- TeacherWhy do ticks and mites live off of other arthropods?
Bugscope Teamit's their niche, in a way
- Bugscope Teamwe find that mites are often on dirty insects, or insects that can't easily clean themselves. The mites might actually help clean them
- Bugscope Teaminsects and other similar arthropods are very opportunistic, and they find many ways of eating/surviving
- Bugscope Teamwe have found that some large centipedes may have hundreds of mites living on them
- Bugscope Teamthere are also many parasitic wasps that are tiny -- to us they look like flies
- TeacherHow are ticks and mites related?
Bugscope Teamthey may both be arachnids
- Bugscope Teamsome mites may not be arachnids
- Bugscope Teamthis is a click beetle!
- 3:35 pm
- TeacherWe looked at some pictures of mites yesterday and it was difficult to tell how many body segments they have
Bugscope Teami think they are similar to ladybugs- they have a big shelled body and their head kind of pokes out with some legs
- Bugscope Teamdustmites are softbodied, so they are hard to image
- Bugscope Teamyes- did they get extra credit for doing that?
- Bugscope Teamthey are a good source of protein
- TeacherNo extra credit!! Ha! We did read an article today about insects being high in iron and calcium and protein and low fat
- Bugscope Teamclick beetles, if you sit on them, will click their bodies, politely asking you to get off
- GuestAlaskan students are brave :)
- Bugscope Teampretty healthy, but it's usually the healthy stuff that doesn't taste good!
- Bugscope Teammmm
- Bugscope Teamthis is the head of some kinda aquatic insect larva
- 3:40 pm
- TeacherIf students open their laptops up again- how can we delegate control?
Bugscope Teamyou can ask us to have a certain student control and we can delegate the control to them
- Bugscope Teamyou can see the palps, which are like little limbs that help insects feed -- taste and manipulate their food into their mouths
- Bugscope Teamcaterpillars have six legs, because they are insects, and the things that look like extra legs are called 'prolegs.'
- GuestIn my classes here, I had two to three students at a time come to the teacher computer to drive and ask questions. just a thought.
- Bugscope Teamthe prolegs often have lots of tiny hooks in them that help the caterpillars cling to surfaces
- Bugscope Teamcaterpillars may also produce web from spinnerets that are on the head
- TeacherOkay- we will have students com up and ask questions off of my computer.
- GuestMeanwhile, other students can take notes and come up with a list of questions in their notes :)
- Bugscope Teamcool!
- Bugscope Teamyou can see the edge of the known world now
- Bugscope Teamthe specimens are all mounted on a 1.75-inch-diameter stub
- Bugscope Teamthe surface of the stub, which is aluminum, has doublestick carbon on it to hold the insects down
- Bugscope Teamand there's also, often, silver paint to help attach them to the stub and also help make them conductive
- 3:45 pm
- TeacherWhat are the petal-like things coming from the bottom?
Bugscope Teamon the caterpillar/larva? those are folds of the exoskeleton where it shriveled after it died
- Bugscope Teamthe caterpillar is very scrunced up from being dried. It is very soft bodied.
- Bugscope Teamwe think this is an aquatic larva, like a stonefly or mayfly larva, that someone sent us. the heads and jaws are hardened shells (chitin, the exoskeleton), but the rest of the body is usually soft, as Cate says
- TeacherUnder captivity, how long would a aqutic catterillar live?
Bugscope Teamit depends on what kind it is; if you fed it well it would eventually metamorphose into its adult terrestrial form
- Bugscope Teamsome larva, once they become adults, have very short lives, some just a few hours
- Teacherwhat kind of bug is this?
Bugscope Teamthis is some type of true bug. we aren't sure what type
- Bugscope Teamtrue bugs have piercing mouthparts they use on either plants for sap for bugs for bug blood
- 3:50 pm
- Bugscope Teamyou can tell it is a true bug because it has those D'Oh Cate
- Bugscope TeamI am so slow
- Bugscope Teamit looks like a Klingon
- Bugscope Teamthe central part of its head is a hydraulic pump that helps it suck liquids up from leaves, or limbs, or from other insects if it feeds on insects
- Bugscope Teamor the queen from Aliens
- Bugscope Teama true bug can often be mistaken for a beetle
- Teacherwhat is the true bug like is it a beetle or if not what is it?
Bugscope Teamthey're not beetles although they resemble them, and they are not the Family Hemiptera, as I had said, but the Order Hemiptera, which includes cicadas, leafhoppers, stinkbugs, and aphids
- Bugscope Teamyes cicadas are true bugs
- Bugscope Teamassassin bugs and ambush bugs, which suck the juice out of other insects, are also Hemiptera
- 3:55 pm
- Bugscope Teamcicadas also have that kind of Klingon-looking central pump on their face
- Bugscope Teamyou can see the compound eyes on either side, and the antennae
- Bugscope TeamI am going to have to slip out...
- Bugscope Teamit was good to work with you today
- Bugscope Teambye from me!
- TeacherThank you for all your help today Scot
- GuestGoodbye Scot
- Bugscope TeamThanks Scott, Chas, Cate! Thanks to Andrea and her bright students!
- TeacherWe are wondering which part of the head has the hydrolic pump
Bugscope Teamit's the ridged part between the eyes
- Bugscope Teamthis is a pinhole from the insect being mounted on a board
- Bugscope Teamwe thought the kids might like to see it
- TeacherThey think that is pretty cool
- GuestThat is amazing!
- 4:01 pm
- Bugscope Teaminsects are a lot hairier than they seem!
- Bugscope Teamhere are some old looking pollen grains that are unfurling (at least the middle one is)
- Bugscope Teamor the top one, I can't really tell
- TeacherIs this pollen found on a spider?
Bugscope Teamyes it was found on the spider, but I'm not sure what kind the pollen grains are
- Teacherthis is fifth period thank you for all the help and answers it was pretty cool
- 4:06 pm
- GuestYou all did a great job!
- Bugscope Teamthanks for using bugscope with us today
- Bugscope TeamWe hope you all had a great time-- you all asked wonderful questions
- Bugscope Teamyou can go back to your chat and text at anytime from your member page-- https://bugscope.beckman.illinois.edu/members/2010-119
- TeacherThis is Andrea- Thank you guys very much- we really enjoyed the session!
- GuestTalk to you soon! It was a pleasure to join you!
- Bugscope TeamThanks!
