- 10:44 am
- Bugscope TeamI am going to run up for food in a minute
- Bugscope Teamok
- Bugscope Teampresets are done. we are ready for the session.
- 10:52 am
- Teacherhi there, just checking in
- Bugscope Teamwelcome to bugscope!
- Bugscope Teami've just unlocked the session, you can start practicing if you want.
- TeacherI still have to get set up with my students---we'd be ready to start at about 11:10 your time...
- Bugscope Teamsounds good.
- Bugscope Teamif you have any questions or problems just let us know if we can help.
- TeacherI'm just going to cruise around a bit..
- Bugscope TeamMs J is this the first time you have worked with this interface?
- Bugscope Teamcoolness, the scope is all yours ms. j
- TeacherNo, I think I used it during our session this past June
- Bugscope TeamIt should be a little better, more responsive
- Teacheryeah, I had some trouble the last time with it now that I recall
- Teacherwow this is so much better!
- Bugscope Team:)
- Bugscope Teamyou have seen us through bad and good
- TeacherI've been doing bugscope with the 5th grade for many years now--I think this is year 5?
- Bugscope TeamChas put this together, and he started working for us when he was a sophomore in high school
- Bugscope Teamnow he is a grad student
- TeacherI feel really old.
- Bugscope Teamthat wasn't intended to make you feel old
- Bugscope Teamwell, i have lots of grey hair...
- 10:57 am
- Bugscope Teamand i'm only 36.
- Teacher:-)
- Bugscope Teamso i LOOK old
- Bugscope TeamI feel older. We've got markings on the ESEM room doorway documenting my height changing about 2 feet
- TeacherOK, I'm going to get set up in my classroom. I'll see you all in about 12 minutes or so...
- Bugscope Teamreally chas? that's cool. where?
- Bugscope Teamyeah that's true I was a lot taller than Chas when he started
- Bugscope Teamcool
- Bugscope Teamoh yeah, i seem the markings now
- TeacherBTW, I think my password was margaret?
- Bugscope Teamyes
- Bugscope TeamYes, but the students shouldn't need it to login
- TeacherOK, thanks.
- Teachersee you in a bit
- Bugscope TeamWhen they visit the login page it should identify them as from the same school and only ask for a chat nickname
- 11:13 am
- TeacherHi, we have one of our 3 5th grade homerooms ready to view some bugs
- Bugscope TeamGreat!
- Bugscope Teamsounds good!
- Bugscope Teamhere we are looking at butterfly scales, very close up
- Bugscope Teamthey are sort of like shingles on a house
- Bugscope Teambut really they function like feathers do on a bird wing
- Teacherwhat type of butterfly was this?
- Bugscope Teamthe one you sent us, a monarch
- Bugscope Teamif you look at the micron bar, to the left, 2 microns is the length of a bacterium
- Bugscope Teamthis is just a piece of the wing
- Bugscope Teami painted the edges with silver paint to help with the charging
- Bugscope Teambutterfly wings LOVE to charge up
- Bugscope Teamwhich is what that weird contrast is
- Bugscope Teamthe whole Monarch would cover the aluminum stub that all of the sample are mounted on
- Bugscope Teamif we want to get good images of the scales close up, we go to an edge where there is silver paint, and we look right adjacent to that
- Bugscope Teamhere is part of an ant
- Bugscope Teamthe left part is a compound eye
- Bugscope Teamthe right is part of the head
- 11:18 am
- Bugscope TeamIt looks like an ant
- TeacherThis is so cool!
- Bugscope TeamAnts usually have very small eyes. They uses smell and "taste" to navigate in their environmnst
- Bugscope Teamenvironment
- Bugscope Teamwith some ants the compound eye is very very simple, like it has only a few ommatidia
- Bugscope Teamthis one has a relatively complex compound eye
- Bugscope Teamand some ants are blind -- they depend only on their antennae
- Bugscope Teamyou can see in the background that Cate put silver paint down to get the ant to stick better and to make a better conductive pathway for the electrons
- Teacherwhy do you have to have a pathway for electrons?
- Bugscope Teamif the elecrtrons that impinge on the sample do not have anywhere to go, the sample will charge up and give us a poor image
- Bugscope Team[electrons] that is what we saw with the Monarch wing, where we had poor conductivity
- 11:23 am
- Bugscope Teamscales are notoriously difficult to make conductive
- Teacherdoes this ant have hairs?
- Bugscope Teammost insects have lots of 'hairs', or setae. ah there are some!
- Bugscope Teamnow you can see a few setae, as Alex said
- Bugscope Teamnow we can see why roly polies are Isopoda
- Teacherwhy are they isopods?
- Bugscope Teamiso means the same, like in an isosceles triangle
- Teacheror not bugs?
- Bugscope Teamthe setae serve a variety of purposes, they help the insect to feel, taste and smell
- Bugscope Teamand pod means foot
- Bugscope Teamall of the feet are the same
- Bugscope Teamthey are not insects
- Bugscope Teamthey are arthropods, though
Bugscope TeamThey're arthropods, but their subphylum is Crustacea meaning they're more closely related to shrimp, lobsters, etc
- Teacherwe just got a huge response from everyone here1
- Bugscope Teamme too, i almost screamed!
- Bugscope Teamyou mean because the pillbug is so lovely?
- Teachereveryone here thinks he looked pretty sad. Probably becuase he's dead.
- Bugscope Teama face only a mother pillbug could love
- 11:28 am
- Bugscope Teamawww
- Bugscope Teamhe does look like hes sad
- Bugscope Teamwe should be able to see his eyes
- Bugscope Teamtasty big insects
- Teacherwhere are the eyes? are they near the antennae
- Bugscope Teamthey should be under the curve of the antenna there
- Bugscope Teamwow you can barely see the eye
- Bugscope Teamthis is the base of the antenna
- Bugscope Teamgood job driving!
- Bugscope Teamok now a tiny bit to the left I think
- Bugscope Teamok
- Bugscope Teamnow you can see those little round beads
- Bugscope Teamoops not now
- Bugscope Teamthe eyes are nothing to write home about
- Teacheryeah, I think I clicked by mistake
- Bugscope TeamYou can probably tell based on the small size of the eye that they do not rely heavily on sight
- Bugscope TeamI had expected they would show up better
- Bugscope Teamthey live in dark places...no need to see things if it is always dark!
- Teacherwhat's a haltere?
Bugscope Teamhaltere's, also known as balancers or poisers, are small knobbed structures found as a pair in some two-winged insects; they are flapped rapidly to maintain stability when flying.
- 11:33 am
- Bugscope Teamdipterans have two wings, and two halteres to balance the movement of the wings
- Bugscope Teamit is a modified wing
- Teachersomeone asked if it is like a rudder
- Bugscope Teamit has those hypertrophied mechanosensors on it, and it beats opposite the way the wings beat
- Bugscope Team@copyright, wikipedia. :)
- Bugscope Teamwhen the fly is alive, the end of the haltere is swollen like a boxer's punching bag -- like a speedbag
- Bugscope TeamNo entomologists refer to them as balancers or poisers...
- Bugscope Teamthey are like gyroscopic stabilizers
- Teacheris this the mouth?
Bugscope Teamyes, you could try to lower the contrast
- Bugscope TeamMs J this is the mouth and you can see the antennae above
- Bugscope Teamsort of mouth
- Bugscope Teamthis looks like it is charging up with electrons
- Teacherwhat are those two ovals at the top?
- Bugscope Teamdeus ex machina
- Bugscope Teamthose are the antennae
- 11:39 am
- Bugscope Teamthe antennae have an oval component and a branched component
- Bugscope TeamFlies have what we call "sponging" mouthparts, kind of like a sponger on the end of a straw connected to their heads...not the most technical of descriptions
- Teacherewwww.
- Bugscope Teamyeah this is gross
- Teacherwhat are all those pointy parts?
- Bugscope Teamthose are tiny setae that probably have to do with tasting the food
- Teacherare the long white ones setae too
- Bugscope Teamlike little taste buds on your tongue
- Bugscope Teamsmall setae and big setae
- Bugscope Teamthey are also called setae, but we call lots of things setae
- Bugscope Teamspme of the longer ones may be mechanosensory like a cat or rat's whiskers
- Bugscope Teameeeuw
- Teacheris that long ribbon the tongue?
- Bugscope Teamthe spongy tongue would be more gross if it was not dried out a bit
- Bugscope Teamyes right in the middle, the curved part
- Teacherdid it die with its tongue hanging out?
- 11:44 am
- Bugscope Teamit pretty much always has its tongue hanging out
- Bugscope Teamso yes
- Bugscope Teamthey spit up on their food to solubilize it so they can suck it up
Bugscope Teambut they dont 'spit up' everytime they land
- Bugscope Teammmmm
- Bugscope TeamI think I am right -- that flies do not chew their food but eat it as a liquid
Bugscope TeamIn some flies...house flies do that
- Bugscope Teamuhoh
- Teacherdid the millipede break? There is a big hole in it.
Bugscope Teami squished it picking it up on accident
- Bugscope Teamhorse flies slash their food so they can suck it up
- Bugscope Teamyeah sorry we broke it
- Teacherouch
- Bugscope TeamMosquitoes, horse flies, fruit flies---I think most flies do consume liquid food
- Bugscope TeamI can say anything as long as Annie is here to correct me.
- Bugscope Teamit's empty!
- Bugscope Teamlooks like there is a scale on the edge there
- Bugscope Teamthen I will have to be more careful
- Bugscope Teamyou can kind of see the dried up muscles
- Teachereww
- Bugscope Teamthe stuff that looks like little pieces of beef jerky
- 11:49 am
- Teacheryum.
- Bugscope Teamwe have looked at mealworms before and seen the muscle attachments on the inside of the cuticle
- Teacheris this millipede decapitated?
- Bugscope Teamyes Cate was so very careless : )
- Bugscope Teamthis is where the head should have been
- Bugscope Teami did not decapitate it
- Bugscope Teamit was already in that state
- Teacherwas this where the head was?
- Bugscope TeamWhere all of this juju is
- Bugscope Teamas alex said before, something chomped on it :p
- Teacherdid you have a live cricket in our "collection of bugs"?
- Bugscope Teamah ha
- Bugscope Teamit was dead when it arrived; maybe that is what killed it
- Bugscope Teamoh Cate said it was alive
- 11:54 am
- Bugscope Teamnow we are looking at scales, up close
- Teacherwe have another group coming in--we'll be back in a minute or two
- Bugscope Teamok!
- Bugscope Teamgreat! we will be here
- Bugscope Teambye bye
- Bugscope TeamBye!
- Bugscope TeamMs J Annie had to leave for a meeting
- Bugscope Teamshe would have preferred to be with us
- Bugscope Teamshe is our entomologist
- Bugscope Teamkeeps us on the straight and narrow
- Bugscope Teamso we dont call lobsters bugs :p
- Bugscope Teamshe did start to concede a little last time -- they do have antennae!
- Bugscope Teamhow many legs do they have?
- Bugscope Teamit has like 10 or something
- 11:59 am
- Bugscope Teamif you include those claws
- Bugscope Teamso it is like an isopoda
- TeacherWe have a new class now so the questions might be similar
Bugscope Teamthats ok we are used to it ^.&
- Bugscope Teambut we might give different answers
- Bugscope Teamthat was super high mag
- Bugscope Teamit is difficult to look at scales closely with the microscope set up this way
- Bugscope Teamwe are far from the sample so we can get good low mag images
- Bugscope Teambut that means when we want to look close we don't have the advantage of better resolution from being physically close
- Bugscope Teamnow you can see charging, where the scales in the middle of this wing segment are lit up
- Teachercan we see the whole butterfly/ wing
- Bugscope Teamit is not all on here Ms J, because it was so big
- 12:04 pm
- Bugscope Teamthis is just a section of it
- Bugscope Teamif we put the whole wing on we would not be able to put anything else on the sample stage
- Bugscope Teamthe scales are what make the wings feel so silky
- Bugscope Teamthey rub off easily, which is part of the reason it is hard to keep them from charging up with electrons when we image them
- Bugscope Teamthis is the ant eye, and the ant's head
- Bugscope Teamnow you can see the antennae
- Bugscope Teamthe jaws are to the NE
- Bugscope Teamif you look towards the mouth you will see little feelers coming out
- Bugscope Teamthe eye is a compound eye, meaning that it has many facets, called ommatidia
- Bugscope Teameach of the ommatidia gets an image
- Bugscope Teamit looks like he's eating something, but it's part of his mouth
- Bugscope Teamnow you can see the jaw
- Bugscope Teamyeah ants often look as if they have some other critter in their mouths
- Teacherwhy does it look like it has small dots on it
Bugscope Teami think those are pores where the setae are coming out
- Bugscope Teamthose dots are places where setae (tiny hairs) stick through the chitin
- 12:10 pm
- Bugscope Teamthe setae are sensory -- they help an insect sense/feel/smell its environment
- Teacherwhy do the have so many scales
- Bugscope Teamthat is the way the cuticle is formed, and it almost certainly makes the structure of the exoskeleton stronger
- Bugscope Teaminstead of being smooth
- Bugscope Teamants have big muscle heads
- Teacherwhat is that hole for
- Bugscope Teamthis one has a little ridge above the ball and socket joint where the antenna is
- Teacherhow is the antennea connected
- Bugscope Teamit is connected at the joint there and has lots of nerves that go inside to the brain
- Teacherhow big is the eye
- Bugscope Teamantennae are very important to an ant
- Bugscope Teamit is a little more than half a mm
- Bugscope Teamyou can see the micron bar to the left
- Bugscope Teamnow we can see the individual facets of the eye -- the ommatidia
- 12:15 pm
- Bugscope Teamthey are generally round, and when they are close packed like this they are often hexagonal
- Bugscope Teamthis is one of the limbs of the pillbug
- Bugscope Teamit is dirty, and I wonder what we can see in the dirt
- Bugscope Teamsometimes there are diatoms visible in dirt
- Bugscope Teamthese guys crawl around on the ground and pick up all kinds of things
- Bugscope Teamyou can see what look like plant parts
- Bugscope Teamthe thing on the bottom is probably plant fiber
- Bugscope TeamOOF
- Bugscope Teammaybe to the left?
- 12:20 pm
- Bugscope TeamMs J is the driving working? It's not hung up is it?
- Teacherwe are not getting an image
- Bugscope Teamtry using the refresh button on your browser
- Bugscope Teamhit refresh
- Bugscope Teamd'oh!
- Bugscope Teamwe lost Cate
- Bugscope Teami'm here i swear!
- Bugscope Teamnow we lost Ms J!
- Bugscope Teamouch
- Bugscope Teamlooks like they lost their internet connection... maybe?
- Bugscope Teami'll try calling.
- Bugscope TeamShe is resourceful she will be back
- Bugscope Teamhi ms. j
- Bugscope Teami'm just trying to call you.
- Studentdon't know if this will work...
- Bugscope Teamit should work now
- Bugscope Teami just gave you control.
- Bugscope TeamYour students will maybe think it is funny that you are signed in as a student
- Studentwe're back...
- Bugscope Teamms. j, try, ah yes, i see you are moving the scope now. coolness!
- 12:25 pm
- Bugscope Teamgood driving!
- Bugscope Teamits like one of those curly up mustaches on his mouth
- Bugscope Teamyou can see the little jaws, now
- Bugscope Teamsharp little jaws
- Bugscope Teamsee the little seta?
- Bugscope Teamto the right?
- Studentyes
- Bugscope Teamms j. occasionally you might see a black screen image. if that happens, and doesn't go away in 3-4 seconds, then try hitting refresh (F5). that should fix it.
- Studentok
- Bugscope Teamnow we are looking right into the mouth, as much as we can, and now we see the setae that probably let it taste what it will be eating
- Bugscope Teamthe eyes are very hard to see because they look more upward than down
- Bugscope Teamnow we see the haltere on the fly
- Bugscope Teamthere will be two of these
- Bugscope Teamone on each side
- Bugscope Teamthey are micro-sized former wings
- Studenteveryone is grossed out
- Bugscope Teamits kind of there, you can see the stem
- 12:30 pm
- Bugscope TeamI think we are used to this by now
- Bugscope Teamhey you found the millipede on your own!
- Studentwhoops
- Bugscope Teamyou can see that when Cate made the sample she mounted the fly on its back
- Bugscope Teamthat is so we can see the legs and face
- Bugscope Teamahhh bright lol
- Bugscope Teamall of those setae that stick out are almost certainly mechanosensory
- Bugscope Teamcool, good control of the brightness/contrast
- Studentwe're assuming that's the eye on the left
- Bugscope Teamoften a female fly's eyes are far apart, like this, and those of a male are close together
- Bugscope Teamyes that is the right eye on the elft
- Bugscope Teamyes, that's a compound eye. a big one.
- Bugscope Teamlefet
- Bugscope Teamyou can zoom in on it if you want
- Bugscope Teamleft
- Bugscope Teamnow you can bring the mag up if you want
- Bugscope Teamall those individual eye facets are called ommatidia.
- Bugscope Teamto see the ommatidia, as Alex says
- Bugscope Teamooh nice
- 12:35 pm
- Studentso these aren't hexagonal
Bugscope Teamah, good eye! i just noticed that. that is interesting isn't it. most compound eye ommatidia are hexogons i believe...
- Bugscope Teamlet's go up close and see
- Bugscope Teamah, wait, these are too!
- Bugscope Teamthey may be hexagonal but angled away from us
- Bugscope Teamjust harder to see
- Bugscope Teamnow adjust the focus a little
- Bugscope Teamthis is exciting
- Bugscope Teameach ommatidium has it's own cornea, lens, and photoreceptor cells.
- Bugscope Teamthis is where we would be able to see bacteria, if there are any
- Bugscope TeamNice!
- Bugscope Teamms. j, you RULE at controlling the scope.
- Studentcould the eye still work if one of the "eyes" is poked out?
- Bugscope Teamthe microscope is parfocal, so if you were to take the mag down you would still be in focus as long as oyu did not move
- Bugscope Teamyes if one eye was poked out or obscured there are a lot of other ones to take its place
- Studentewww
- Bugscope Teamthe brain is largely devoted to optic nerves -- to visual processing -- in a lot of flies
- Bugscope Teamcompound eyes have poor resolution in general, however they are GREAT for detecting fast moving, like other bugs and such. compound eyes also have a very WIDE angle of view, so they can see lots of stuff.
- Bugscope Teamsome insects can also see in the ultraviolet -- out of the range of visible light
- 12:40 pm
- Bugscope Teamwe cannot see in the ultraviolet
- Bugscope Teamsome eyes like fly eyes have almost 360 degree view
- Bugscope Teamthis is the edge of the fly tongue
- Studentlots of screaming
- Bugscope Teamthe eye to the left (the right eye) is busted
- Bugscope Teamme too! ahhhh!!!!!!!
- Studentyuk
- Bugscope TeamCate is such a savage she must have dropped the fly
- Bugscope Teami didnt do it before you blame me scott >.>
- Bugscope Teamon the top of the head are the antennae
- Bugscope Teamtoo late Cate
- Bugscope Teamwow! the compound eye is cracked! very interesting.
- Bugscope TeamActually I don't know how you would do this on purpose
- Bugscope Team*sigh*
- Studentshould I use the + or - to focus?
- Bugscope Teamso you know I was just teasing Cate
- Bugscope Team+
- Bugscope Teamit's hard to know which one. try one, if it gets worse, then use the other.
- Bugscope Team'cause I just tried it
- Bugscope Teamcool
- Bugscope TeamNice!
- Bugscope Teamwow, i've never seen a cracked compound eye before, this is sweet!
- Bugscope Teamthis is a good opportunity to see what is inside
- Bugscope Teamwow
- 12:45 pm
- Bugscope TeamIt looks fibrous
- Studentis that muscle under the eye?
- Bugscope Teamare those muscle fibers under the facets?
- Bugscope TeamI imagine those are lots of nerve bundles
- Bugscope Teamthey have to be linked well to the brain
- Studentthis is really cool
- Bugscope Teamyeah, that makes sense, they don't need muslces there, they just need nerves to send the signals to the brain....
- Bugscope Teami'm guessing though. i'm not a biologist.
- Bugscope Teamyou know the ommatidia looked more like lenses than I had thought -- like little crystals
- Bugscope Teameeeeuw
- Studentwhat is this?
- Bugscope Teamthis is one of the spiracles
- Bugscope Team this is an airhole
- Bugscope Teamthis is what insects breathe trhough
- Bugscope Teamthrough
- Studentis this on the mouth?
Bugscope Teamgopod question, but no, spiracles are usually on the body of insects.
- Bugscope Teamthere are usually two on each body segment, on either side
- Bugscope Teamno it is just on a body segment
- Bugscope Teamwe have to remember that insects have an exoskeleton, which means the hard bony part of the body is on the outside
- Bugscope Teamimagine if you breathed through a hole on the side of your body. cool huh?
- Bugscope Teamyou can see its butt
- Bugscope Teamit is like if you were wearing armor all of the time
- 12:51 pm
- Bugscope Teamif you were wearing armor you would not be able to use the nerve endings in your skin to feel what might be touching you
- Bugscope Teamoo good analogy
- Bugscope Teamso you would want something to stick through the armor that would send a touch or smell message to your skin
- Bugscope Teamthat's why insects have the setae (hairs) that stick through the armour. those setae help the insect to sense it's environemnt. yeah, scott, good analogy, you are on fire today!
- Studentgood one!
- Bugscope Teamand also you would want to be able to breathe through your armor
- Studentok, we have another group coming in...give us a few minutes.
- Bugscope Teamwhich is what spiracle are for
- Bugscope Teamspiracles
- Studentthis will be our last group, too.
- Bugscope Teamok, this is fun.
- Bugscope Teaminsects can close their spiracles and hold their breath, like if you put then in the microscope alive they would just hold their breath until you let them out again
- Bugscope Teamthough i'm sure they won't like getting hit with electrons
- 12:57 pm
- Studentone group is delayed. so bear with us!
- Bugscope Teamwe are fine -- thanks!
- Bugscope Teamno problemo
- Bugscope TeamIf we put a live roach in the 'scope and imaged it for a few minutes it could just hold its breath until we let it out again
- Bugscope Teamyep, but it would have to stay still
- Bugscope TeamMan there is not much air in here so I am going to close my spiracles.
- Bugscope Teamwe would have to use wax tethers
- Bugscope Teammaybe use some of that sticky stuff from a roach motel to keep it still
- Bugscope Teamif it doesn'
- Bugscope Teamt outgas
- Bugscope Teamkeep those spiracles closed tight!
- 1:03 pm
- Bugscope Teamyay!
- Studentwe're back with a new group
- Bugscope TeamGreat!
- Bugscope Teamthis is the millipede
- Studentis there a double set of legs at the top curve?
- Bugscope Teamand you can see in some places where there are scales on it from a butterfly wing
- Bugscope Teamlet's go look!
- Bugscope Teamwe can figure out how many legs it has per segment
- Bugscope Teamyou can try click to center if you want, sometime
- Bugscope Teamwhen you use click to center you don't have to stop
- Bugscope TeamI think there are pairs of legs that are opposed
- Bugscope Teamit is hard to see where they orginate
- Bugscope Teamoriginate
- StudentOk, it just looked a little dense there.
- Bugscope Teamhere is where the head was, and where we think the cricket had a little snack
- Studentwhat is all this stuff coming out of its body
- 1:08 pm
- Bugscope Teamyeah lot of stuff
- Bugscope Teamin insects the blood is called hemolymph
- Bugscope Teamthis is analogous to that I think
- Studentso, maybe this is dried blood
- Bugscope Teamthey have an open circulatory system, and I think it is the same with millipedes and roly polies
- Bugscope Teamall of the organs inside the body cavity are bathed in that fluid, which is hemolymph in insects
- Bugscope Teamhere is where the cuticle broke
- Studentthese kids are curious about the hole
- Bugscope Teamask cate about it ; )
- Bugscope Teami poked it picking it up
- Bugscope Teamit crunched
- Bugscope Teamyou can tell that the exoskeleton is very dry now
- Bugscope TeamWell...now we get a little peak inside
- Bugscope Teamheh it all oozed out when its head popped off
- Bugscope Teamsee where things are very white? that is whre the electrons are not going to ground
- Bugscope Teamwe may be seeing muscle now
- 1:13 pm
- Bugscope Teamwhen we prepare samples we coat them with gold-palladium to make the surface conductive
- Bugscope Teamwhen we use an electron microscope the sample is in a vacuum, and we beam electrons at it
- Bugscope Teamthe electrons pass across the sample in an orderly, repeated manner
- Bugscope Teamand they knock other electrons out of the coating on the surface of the sample
- Bugscope Teamthe electrons that come out of the sample are called secondary electrons, to distinguish them from the beam, which is primary electrons
- Bugscope Teamall this will be on tomorrows exam...
- Bugscope Teamwe collect the secondary electrons into the images we see
- Bugscope Teamheh
- Studentwhat are the scales made out of?
- Bugscope Teamthey are made out of protein, and it is still chitin I think
- Bugscope Teamlike what the exoskeleton is made out of
- Bugscope Teambutterflies, moths, skippers, mosquitos, and silverfish have scales
- Bugscope Teamif you go closer, you'll see that the scales have ribbed parts (thicker) and then thin parts inbetween that quite often have holes in them.
- 1:18 pm
- Bugscope Teamor, how about always have holes in them.. wow. is that normal scott?
- Studentare those spaces between each?
- Bugscope Teamit seems like they always have holes in them but the patterns can be very different
- Bugscope Teamyes those are spaces
- Bugscope TeamI am still not sure if scales have colors
- Bugscope TeamI think they do
- Bugscope Team but they are small enough to refract light and give you structural colors
- Bugscope Teamlike if you look at the surface of a record, or if you look at the feathers on a crow's wing and they give you multiple colors
- Bugscope Teamthose are also called or more properly called interference colors
- Bugscope Teamwe lost Ms J again!
- Bugscope TeamMaybe she was bored listening to me...
- Bugscope Teamyay you're back
- StudentWe're back, again!
- Bugscope Teamhi ms j 2!
- Bugscope Teamno that couldn't be it
- StudentNo, you weren't boring us.
- Bugscope Teamyay!
- Bugscope Teami just gave you control, it should be working again.
- 1:23 pm
- StudentI can't get to the other specimensit says valid session ID not received?
- StudentoK, we're back
- Bugscope Teamhmm, try hitting refresh (F5), and then try again.
- Bugscope Teamyay!
- Bugscope Teamthis is the ant eye, and the surface of the side of the head
- Bugscope Teamit haas little crenulations in it
- Bugscope Teamthat probably make the surface much stronger
- Studentwhat's a crenulation?
- Bugscope Teamit means having an irregular or wavy appearance
- Bugscope Teamor a serrated outline
- Bugscope Teamvery similar to crenelations in a castle
- Bugscope Teamlike the top of the wall of a castle with those places to shoot bows and arrows and cannons through
- Bugscope Teamthis is the antenna base
- Bugscope Teamits a ball and socket joint it looks like
- 1:28 pm
- Bugscope Teamwe can see what looks like mold on the surface of the ant
- Studentwhy does the ant have such long hair
- Bugscope Teamand lots of tiny setae
- Studentthat's mold?
- Bugscope TeamIt's like what grows on your food when it rots -- those fine fibers
- Bugscope TeamReally, Scott...
- Bugscope Teamabdomen
- Bugscope Teamsorry
- Bugscope TeamI didn't read your question right, I am sorry
- Bugscope Teambut now you can see that the setae are covered with mold
- Studentwe just were curious about the mold.
- Bugscope TeamWhat happened was that the ants were in a container that we closed the top on, and mold that was already in the air started to grow on them
- Bugscope Teamit would have been better if we had not closed the top of the container
- Bugscope Teamso there were lots of setae (hairs), and there was mold attached to them
- 1:34 pm
- Bugscope Teamthis is the mouth of the roly poly
- Studentdo roly polys have a tongue?
- Bugscope TeamI don't know; I think we are seeing as much of the mouthparts as we usually see, and it looks like these parts cut the food
- Studentlooks like a crab mouth.
- Bugscope Teamwell it is related to crustaceans, so you are right
- Studenta student is curious to know if you could tell the age of some of the bugs
- Bugscope Teamand you know when you see them eat their mouths move in many directions
- Bugscope TeamWe know that when an insect gets wings it becomes an adult, like a fly for example, and it does not grow after that. So if you see a small fly it will not be growing up into a large fly.
- 1:39 pm
