- Bugscope Teamstarting presets
- 10:53 am
- 10:59 am
- 11:05 am
- 11:10 am
- Bugscope Teamdone with presets, we are ready anytime
- Bugscope Teamunlocked the session just now
- 11:15 am
- Bugscope Teamhello kristen!
- Bugscope Teamhi kristen, welcome to bugscope!
- TeacherHello!!
- Bugscope Teamwe are ready anytime
- Bugscope Teamyou should see microscope controls on your right, and presets below that
- TeacherWe are waiting on another class to come in. They should be here on or before 11:30 your time.
- Bugscope Teamyou can try driving the scope now if you want to pratice
- TeacherThanks! I will go for it.
- Bugscope Teamcool
- Bugscope Teamnice job driving. watch the edge of the scope though, if you run over the edge, we need to fix it. not a big deal, but there's nothing to see over the edge anyway :)
- Bugscope Teamusing "click to center" is a little easy than "click to drive", especially for fine tune control.
- TeacherSo if I click to center, where should my mouse be?
Bugscope Teamclick anywhere in the image. it will center on that location
- 11:21 am
- Bugscope Teamwherever you point your mouse and click for click to center, it will center in that position
- Bugscope Teambut you need to cancel the click to drive first
- Teacherwhoaa!! Ok, sorry. I got it.
- Bugscope Teamok, we ran off the edge, and now i'm fixing the scope, clicked on a preset, now it's yours again!
- Bugscope Team:)
- Bugscope Teamgo for it
- TeacherThanks Alex!
- Bugscope Teamif you ever get lost driving the scope, you can click on a preset, that will take you to that location
- Bugscope Teamcan you cancel the click to drive function, it's on the right side of your browser, the navigation area
- Bugscope Teamooh nice
- Bugscope Teamok, it's yours again Kristen
- Teachermuch better. thank you
- Bugscope Team:)
- TeacherWhat is this?
- Bugscope Teamthis is a centipede, it's head
- Bugscope Teamit is upside-down, on its back
- Bugscope Teamthis is the head portion of a centipede; you can see its powerful piercing mouthparts
- Teacherway cool
- 11:26 am
- Bugscope Teamnow you can see the multiple body segments
- TeacherCel wants to know if we can print a picture of our guy out?
Bugscope Teamwell, you could use some software to print the contents of your browser window. but we do all the work for you already. all the images and chat from this session are saved to your member page: http://bugscope.beckman.illinois.edu/members/2009-036
- TeacherAre the smaller "legs" attached? They look like they might be broken?
- Bugscope Teamall of these images go to your database, so the more you drive around and look the more you will be collecting images that you can download and print later
- Bugscope Teamthe centipedes sent weren't in this best condition. this is the better one that had some legs intact still
- Bugscope Teamyour bugscope member page is also linked in the original reply you got from us when you applied for bugscope
- Bugscope Teamand if you have any trouble finding anything, you can always ask us at: bugscope@itg.uiuc.edu
- TeacherWe had been collecting for some time so some of our friends might have come in pieces. Sorry.
- Bugscope Teamno problem at all -- sometimes we get fresh samples that don't look this good
- Bugscope Teamit's no big deal. we are used to seeing worse
- Bugscope Teambe sure to take the mag up to look at interesting places
- 11:31 am
- Bugscope Teamhey cool you found this little fly!
- TeacherHe's so interesting
- Bugscope Teamsee the compound eyes? they make up a huge proportion of the head
- Bugscope Teamyou can take the mag up to see them better
- Bugscope Teamyay
- Bugscope Teamnow you can see the facets of the eye, called ommatidia
- Bugscope Teamand lots of tiny hairs we call 'setae'
- Bugscope Teamyou can go still higher, of course
- Bugscope Teamand you can use 'click to center' to help you center on the eye
- Bugscope Teamif you would like
- Bugscope Teamthere are also setae in between the ommatidia
- Bugscope Teamand you found what looks like a mold spore here
- 11:36 am
- Bugscope Teamthe ball is a mold spore as scot says
- TeacherWe are just amazed. Sorry we haven't asked a lot of questions but we are sitting in awe!
- Bugscope Teamsee the micron bar, in the lower left of the image?
- Teacheryes
- Bugscope Teama normal rod-shaped bacterium -- a bacillus -- is about 2 microns, or micrometers, long
- Bugscope Teamthis is the mouth
- Bugscope Teamin the middle is the fly tongue
- Bugscope Teamor as Cate says more specifically it is the tongue
- Teacherlet's check it out!
- Bugscope Teamit does not look as good as it would it real life because it has dried and shriveled somewhat
- Bugscope Teamyou can see a few more mold spores
- Bugscope Teamsometimes we will find pollen grains, which are similar in appearance
- 11:41 am
- Teacheralex wants to know if they have taste buds?
Bugscope Teammany insects have tiny feelers called palps that function as accessory mouthparts and have very small setae on them. some of those setae are chemoreceptors, and an insect can taste its food using them. so they are much like tastebuds
- Teacherwhat are all the little hairs on the wing?
Bugscope Teamthose are microsetae, or microtrichae, and they likely do not have a sensory function. they may serve to help add surface area to the wing, and they may also help prevent wet wings from sticking together
- Bugscope Teami'm not sure what the hairs on the wing do for functionality
- 11:46 am
- Bugscope Teamjust know that insects are a lot hairier than they seem, and a lot of the hairs serve the purpose of helping the insect to feel what's around them, kind of like how our soft skin works to help us feel temperature and touch
- TeacherThe presets that are on the right bottom of the screen...do I just click on those? Are they our bugs?
Bugscope Teamyes, click on the. those are just interesting locations that we saved for you, so you can go to them quickly whenever you want to
- Bugscope Teammost of the insects in the presets are yours
- Bugscope Teamwe did add some of our own
- 11:51 am
- Bugscope Teamthe dark spot is where it is starting to decay
- Bugscope Teamsome oil is coming out of the exoskeleton
- Teacherok We thought it was a boo-boo ;)
- Bugscope Teami guess that is similar
- Bugscope Teamthis is a boo-boo
- Bugscope Teamwe are focusing for you every once and a while, makes better images
- 11:56 am
- Bugscope Teamfocusing can be hard to control, so it's not a problem
- TeacherI thought so. Thank you for your help!
- TeacherJake wants to know if this is a mole.
Bugscope Teamno thats not a mole, it's another mold spore. There was quite a mold contamination among your insects
- TeacherWe have another class coming in right now...more questions to come.
- Bugscope Teamcool, we are ready
- Bugscope Teamit is normal for insect specimens to get mold on them; if things did not rot there would be huge piles of dead insects and plants and animals all around us
- Bugscope Teamlook at the antennae, at the top of the head!
- 12:01 pm
- TeacherWhat part of the antennae are we looking at? It looked like an egg with a "leg" sticking out
- Bugscope Teami'm not sure, can you zoom out and we can get a better look at it?
- Bugscope TeamThere are 2 parts to a fly antenna. I dont know their scientific names but there is a pad, furry part, and a branch
- Bugscope Teamwhoa
- Bugscope Teamthere are sensory area on the furry part used for smelling things
- Bugscope Teama lot of setae are used to smell things. those setae are called chemosensory setae
- TeacherLet's look at the mouth area
- Bugscope Teamok, that's a cool area. the proboscis is somewhere in there
- Bugscope Teamone of the legs is covering up part of the mouth sadly, but you can still see part of the tongue
- 12:07 pm
- Bugscope Teamthat's what the fly uses to spit out a digestive liquid, and then suck up its food, kinda gross, but hey, whatever gets the next meal into your belly...
- TeacherIf we eat food that a fly has been on, is that liquid what makes us sick?
- Bugscope Teamwell, i'm not sure, but i kind of doubt that the fly digestive liquid would have any effect on humans. it's all the bacteria and the like that fly's touch, that's what hurts humans
- Bugscope Teamof course if you created a gallon of that fly liquid, that would probably be bad for you
- Bugscope Teambut any normal fly dose probably wouldn't hurt a human
- Bugscope Teamew alex
- Bugscope Teamsorry ;)
- Bugscope Teamha
- Teacherwell, we asked!!
- 12:12 pm
- Bugscope Teamthese are special hairs that allow insects to walk on walls
- Bugscope Teamtenet setae are very cool, they are what help the insect stick to walls and sucj
- Bugscope Teamsuch
- Bugscope Teamthey act like suction cups or velcro
- Bugscope Teamnow you can see where we were
- Bugscope Teamand you can see the claws
- Bugscope Teamthey actually don't use a sticky substance, the tenent setae use a force, called the van der waals force. it is a very week force, but when you have thousands of little tenent setae, the force adds up enough to hold the insect to a wall...
- Bugscope Teamwe can tell, pretty much, if a particular insect would be able to walk on a window, or on a ceiling, by looking at this part of the tarsi. The tarsi are the final segments of the leg or arm.
- Bugscope Teamlike in the movie spiderman when he has the hairs growing out of his hands
- Bugscope Teamthat he uses to walk on the building's walls
- Teachercool stuff
- TeacherWhat is syrphid fly haltere
- Bugscope Teamthis is one of the halteres, which flies (Diptera, meaning 'two wings,' use to balance the motion of the wings.
- Bugscope Teama haltere is something flies have that they use to beat opposite their wings as they fly
- 12:17 pm
- Bugscope Teama syrphid fly is also known as a hoverfly
- Bugscope Teamthey hover over flowers
- Bugscope Teamand kind of look like a wasp because of the bands of yellow and black on their abdomen
- Bugscope Teamthis is where a pin was stuck in the insect
- Bugscope Teamit was in a display case before i took it out
- TeacherOK. too funny. we were wondering if that was really a hole.
- Bugscope Teamthis claw is different. do you think this beetle would be able to walk on walls?
- Bugscope Teamwe would have to look further down the 'arm' to see if it had little pads of tenent setae like the fly had
- Teacherwe vote no
- 12:22 pm
- Bugscope TeamI bet you are right.
- Bugscope Teamthere is a cord like a tendon inside this part of the 'arm' that pulls to close the claw
- Teacheryeah!
- Bugscope Teamthis beetle really got around, picked up a lot of junk
- Bugscope Teamthe beetle is covering its mouth with its forelimb
- TeacherOne of our "bugs" looked like a fly with feather wings. they were white and feathery but when we put him with our other bugs, his wings got tangled up and caught on all the other bugs. I don't know what he was but we were sad that his white wings didn't make it.
- 12:27 pm
- Bugscope Teamaww
- Bugscope Teamthis is a little colony of mold
- Bugscope Teaminsect mouths open sideways compared to ours
- Teacherwow that is something else to see!! We are glad they don't BITE too!!
- Bugscope Teamthis is one of the jaws, which have sort of hinges and open/close like a gate
- 12:32 pm
- TeacherDo we have the whole wasp? his stinger? or just the head?
- Bugscope Teamthe whole wasp is in there, but you cant see the stinger
- Teacherok. thank you.
- TeacherI see our time is up. I can't believe it has been an hour. Thank you SO much for everything. We would love to do this again next year.
- Bugscope Teamremember to check your member page for all the chat and images from this session
