- Bugscope Teamokay we are ready to roll!
- Bugscope Teambrb
- TeacherRight on! I am just about to introduce the live session to my students. Thank you for being here!
- Bugscope Teamhello!
- Bugscope Teamyou have control
- Bugscope Team29 presets
- Bugscope Teamthis is a grasshopper claw
- 6:56 pm
- Bugscope Team321x
- 7:01 pm
- Bugscope Teamwasp head
- TeacherThanks for the narrative - we like this image :)
- Bugscope Teamnot much of a narrative
- TeacherScott tell us about this wasp.
- Bugscope TeamI was trying to figure out what the spore containing bodies are called
- Bugscope Teamthis is a wasp I found in the stairwell this morning
- Bugscope Teamyou can see that it has mandibles, like those of other insects, that open from side to side like a gate
- Bugscope Teamand you can see its compound eyes, which have thousands of ommatidia -- the individual facets of the eye
- Bugscope Team you can also see the antennae, which to many insects are at least as important as the eyes. to ants, which are closely related to wasps, they are likely more important
- 7:07 pm
- Bugscope Teamantennae have lots of sensory setae and other organs such as placoid sensilla, on them
- Bugscope Teamsensory setae are found all over the exoskeleton; some are chemosensory, some are mechanosensory, and some may be thermosensory
- Teacher placoid sensilla???
- Bugscope Teammany flying insects, like bees, and this wasp, also have simple eyes, called ocelli, on top of the head -- three of them
- Bugscope Teamplacoid just means 'plate-shaped,' and they resemble, often, oval pushbuttons
- Bugscope Teamin some cases the placoid sensilla seem to give the insect information about how the particular limb they are on may be deforming
- Bugscope Teamor just changing shape, but stressed so that the insect can sense the stress
- Bugscope Teamnow we are on one of the compound eyes
- Bugscope Teamyou can compare it to the moth eye, which appears to be much more complex
- 7:12 pm
- Bugscope Teamwasps like sugary stuff, but they don't make honey like bees do
- Bugscope Teamyou can see that the jaws -- the mandibles -- are serrated, or like forks
- TeacherWe are fascintaed by the mouth. Why the "overbite?"
- Bugscope Teamif it didn't have an overbite it wouldn't fully close
- TeacherDo they have tongues?
- Bugscope Teamyou can see the edge of one of the palps just beneath the rear mandible
- Bugscope Teamsome insects have what function like tongues, but I don't think the wasp does
- Bugscope Teambees have something called a 'glossa' that is much like a tongue
- TeacherWhat is the function of the small setae on the "upper lip"?
- Bugscope Teamthere are usually four palps -- two mandibular and two maxillary, that help the insect manipulate and taste its food
- TeacherCan you drive us to: edge of one of the palps just beneath the rear mandible
- Bugscope Team we don't know if they are mechanosensory
- Bugscope Teamthese are much more obvious on the ant mouth
- Bugscope Teamif you click on that preset
- Bugscope Teamand they are Hymenoptera as well -- they're related!
- 7:17 pm
- Bugscope Teampalps are small accessory limbs that help insects eat
- Bugscope Teamthey don't count as legs or arms
- Bugscope Teamyay! Ants often look like they have an entirely separate critter in their mouths
- Bugscope Teamyou can see the mandibles, again
- Bugscope Teamants have a long first segment of the antenna, whereas wasps do not
- TeacherWhoah - now you got us excited!
- Bugscope Teamsorry I just wiped out the other confuser
- 7:23 pm
- Teacher??
- Bugscope Teamlot of detail in the antenna, but it is foreshortened quite a bit in this view
- Bugscope Teamthis is interesting -- I am not sure what it is but it seems much like an ear drum
- Bugscope Teamon the grasshopper's leg
- Bugscope Teamthere is so much to know about insects, and we barely touch the surface
- Bugscope Teammost insects do not have ears
- Bugscope Teamthey sense vibration (sound) using their setae
- Bugscope Teamspiders have plumose setae that are especially sensitive to vibration
- Bugscope Teampraying mantises are said to have a single large ear on the thorax
- Bugscope Teamnot sure that we have seen it for sure
- Bugscope Teamjust like roly polies, which are crustaceans, are said to have gills
- Bugscope TeamI am sure they do, but we have not seen them for sure
- 7:28 pm
- Bugscope Teamgrasshoppers often have an inflatable ball-like membrane called an arolium between their claws
- Bugscope Teamthey can puff it up with hemolymph, and it helps them hold onto a surface
- Bugscope Teammost of the insects we see have, instead, tenent setae on a pad called a p
- Bugscope Teampulvillus
- Bugscope Teamtenent from tenir, or tener, to hold
- TeacherCan you tell us what this is?
- Bugscope Teamit's a little ball that holds a boatload of mold spores
- Bugscope Teamwhen it pops open it flings them all over
- Bugscope Teamyou can see some mold spores now
- Bugscope Teamoften they are caved in, flattened on one side
- TeacherWhat is this on?
- Bugscope Teamthey resemble red blood cells
- Bugscope Teamin a way
- Bugscope Teamthis is the abdomen of a cranefly
- Bugscope Teamthe head is to the north, but it is also a preset so you need not drive
- Bugscope Teamnow you can see one of the halteres
- 7:33 pm
- TeacherWhat is a halteres? Can you drive us to one?
- Bugscope Teamhalteres are what Diptera -- two winged -- flies use to balance themselves in flight
- Bugscope Teamthe halteres beat with a motion opposite that of the wings
- Bugscope Teamyou can see the haltere now -- it's a long stick with a shrunken boxing speedbag at the end
- Bugscope Teamthey look like speedbags when they're not, like, desiccated
- Bugscope Teamwhen we use the microCT to look at them, they have some kind of mineral inside, at least the ones we've seen, and we assume that it adds weight to the haltere
- TeacherThanks for all the information. This is Steve and Eric
Bugscope Teamhi you guys!
- Bugscope Teamthis is an ant's claw, one of six of course
- TeacherIs the body in the middle also like an ariolum in the claw of the wasp?
Bugscope Teamyes that's right!
- 7:39 pm
- TeacherIs it strictly for grip? on an object, or perhaps to amnipulate objects?
- Teacher*manipulate
- Bugscope Teamwe think it is to help hold onto a surface, but certainly it could help in manipulating something
- Teacherwhy is the abdomen scaly
Bugscope Teamthe scaly shape may provide strength, may make the abdomen more resistant to being squished
- 7:44 pm
- Bugscope Teamalso, the scaliness may make the ant appear shiny black
- Bugscope Teamsometimes, like on the click beetle, those tiny features make it look extra shiny
- Bugscope Teamand things like that help other insects recognize it
- Bugscope Teamwith ants, though, they really do most of their business using their antennae
- Bugscope Teampheromones are a big deal
- Bugscope Teamsome ant species don't even bother to have eyes
- Bugscope Teamthis is another hymenopteran
- Bugscope Teamwith hairy eyeballs
- Bugscope Teamfruit flies have small stiff bristles in between the ommatidia that help them monitor windspeed and direction
- Teacherwhy do they have hairy eyeballs?
Bugscope Teamnot sure
Bugscope Teamprobably to help catch more pollen since the hairs are similar to the body hairs
- 7:49 pm
- Bugscope Teamthis is a badboy killer insect
- Bugscope Teamand old-school; they've been around for millions of years
- Teachertell us some interesting facts about the dragonfly?
- Bugscope Teamthey are one of the fastest flying insects
- Bugscope Teamthey have four wings, and they get along just fine without having to hook them together to fly, like bees and wasps
- Bugscope Teamdragonflies have little hooks on the back of their head to help hold their head on when they're mating
- Guestthe teacher got logged out
Bugscope Teamso we gave you control...
- Bugscope Teamwww you can drive now if you want
- Bugscope Teamdragonflies heads fall off easily
- Bugscope Teamyes they are super agile; I'm sorry I don't know how fast it translates to
- TeacherWhat is all the confetti looking stuff?
- Teacherhow fast can the fastest dragonfly fly?
Bugscope Teamthey can fly 19-38mph!
- Bugscope Teamalso, if you look up close (use the preset, actually), you can see that the dragonfly also scarfed up at least one leafhopper
- 7:54 pm
- Bugscope Teamgo to the brochosomes preset
- Bugscope Teamthis is something we rarely see
- Bugscope Teamthe busted wing scale
- TeacherCan you please take us to the scarfed up leafhopper, oh wise one.
- Bugscope Teamokay let me focus this with the microscope
- Bugscope Teamthis is all that's left of the leafhopper
- TeacherHow fast do they beat their wings?
Bugscope TeamIt is estimated in some species of Darners to be around 28 beats per second.
- TeacherThanks Cate!!
- TeacherWhat is a brochosome?
Bugscope Teamthey are spherical and sometimes oval little particles that are produced in the Malpighian tubules and applied to the exoskeleton in an 'anointing function'
- Teacherand arent they super agile?
Bugscope Teamthey have great visual responses and with their speed, that makes them pretty agile in flight
- 7:59 pm
- Bugscope Teamits head is mostly eyes
- Bugscope Teambrochosomes are made only by leafhoppers
- TeacherVery cool information! This is Dr. korb again... we are signing off for the night! Thanks for everything!

- Bugscope TeamThank you!
- GuestIs there a link?
- GuestHow can we do this with our elementary school students?
Bugscope Teamif you go to the Bugscope home page you can fill out an application
- Bugscope TeamIf you went to https://bugscope.beckman.uiuc.edu/ you there are easy to follow directions on filling out an application
- Guestokay, thank you so much!
- Bugscope Teamhttps://bugscope.beckman.illinois.edu/
- Guestyou guys were amazing!
- Bugscope TeamD'Oh!
- Bugscope TeamThank You!
- Bugscope Teamif you have access to multiple computers (assuming they are old enough to use them by themselves) you can even have them each log in if you wanted
- Guestwonderful
- Guestwe greatly appreciate it
- Bugscope TeamYes! often we can let the kids drive, if *you* let them
- 8:06 pm
- Bugscope Teamwahwahwah we are out the door -- Thank You!
