- 8:07 am
- Bugscope Teamvac ok, beam on.
- 8:14 am
- Bugscope Teamstarting presets
- 8:21 am
- 8:27 am
- 8:32 am
- Bugscope Teampresets are finished, we are ready for the school!
- 8:42 am
- Bugscope Teamsession is unlocked.
- Bugscope TeamI think I am going to drive around a little.
- 8:47 am
- Bugscope TeamHello MB!
- Bugscope TeamWelcome to bugscope!
- 8:52 am
- TeacherHi what is that on the screen?
Bugscope Teamwe are currently looking at setae on a moth.
- Bugscope TeamCate did all the presets this morning, and I was just looking around.
- Bugscope Teammary beth, if you have any questions please don't hesitate to ask. we are ready for you and your class anytime.
- Bugscope Teamearlier I had been on part of the seed; now we are on the moth setae, as Alex said
- Bugscope TeamPlease try driving, if you would like. And let us know if you have any questions.
- TeacherWhat is a setae? what body part is it attached to, is it the thorax
- Bugscope Teamsetae is plural for seta. a seta is a "hair" that comes out of the body of an insect. the setae help an insect sense its environment
- Bugscope TeamThe presets are often made to incite your curiosity -- to make you wonder what thhis things you see is attached to.
- TeacherI think I am good with driving. so far, I have focused, and hit center image.
- Bugscope TeamIf you take the mag down you can see what the setae are attached to.
- Bugscope Teamthere are many many setae on insects, which you normally don't see with your own eyes!
- Teachershould I go out for mag?
- Bugscope Teammany people are often suprised by how "hairy" insects really are
- Bugscope Teamyep, give it a shot.
- Bugscope Teamyes this is good
- Bugscope Teamyou can start to see where you are, right now of the edge of the body
- Teacheris this a stinger in the center of our screen
- Teacheris 154X going out?
- Bugscope Teammoths are notoriously difficult to image because all of the tiny setae are hard to make conductive
- Bugscope Teammary beth, if you ever get lost driving, or want to look at something new, you can click on a preset (lower right), and that will take you to interesting places that we've setup for you
- 8:57 am
- Bugscope Team154x is going to a lower mag than where you were
- Bugscope Teamit is hard to tell what that is; maybe if you go still lower in mag
- Teacherare we close to the abdomen?
- Teacherokay, I see I need to go out
- Bugscope TeamIt looks like we are centered on the abdomen and have wings folded to the sides.
- Bugscope Teamif you go north you should reach the head
- Bugscope Teamas you are doing
- Teachermoving up to find the head?
- Bugscope Teamso that was probably a claw -- the tip of a claw
- Teachergreat minds think alike
- Bugscope Teamyou can see scales at the sides of the image
- Teacherabout how long is one wing
- Teacherohhhhhhhh are these eyes?
- Bugscope TeamI think one wing is between 1 and 2 cm long
- Teacherwe are thinking this is really cool.
- Bugscope Teamthere is the head with the tongue in the middle all rolled up
- Bugscope Teamyou can adjust the contrast to cut the whiteness down
- Teachercan we save the chat?
Bugscope TeamYes, all the chat and images are automatically saved and made available from your member's homepage after the conclusion of the session
- Bugscope TeamNow the eyes are visible as those two big round shapes. If you bring the contrast and brightness down you will see the individual facets of the compound eye
- Bugscope Teamunder 'adjust'
- Bugscope Teamflying insects generally have really big eyes, giving them almost a 360 degreee view around them
- 9:03 am
- Teacherthanks for the tips
- TeacherThis is so cool.
- Bugscope Teammb, your member homepage, in case you don't remember, is: http://bugscope.itg.uiuc.edu/members/2007-065
- Bugscope TeamThere we go, now we're starting to see some detail in the eyes
- Bugscope Teamah, nice, check out the compound eye, and all the little ommatidia
- Teacherwe are going into the eye
- Bugscope Teamwe're going in, hold onto your seats!
- Teacher]seatbelts are on!!
- Bugscope Team:)
- Teacherwe are amazed. It is like being in the Magic School Bus
- Bugscope Teamnotice the shape of all the ommatidia, i believe in most, if not all, compound eyes, the ommatidia are always hexagons. is that right scott?
- TeacherIs there a reason for hexagons?
Bugscope Teamwell, the compound eye is curved, so maybe the hexagonal shape helps the eye to become curved? yes, like scott says...
- Bugscope Teamthey end up being hexagonal when they close-pack like that
- TeacherThe hexagon has 6 sides.
- 9:08 am
- Bugscope Teamit is the most efficient means of making something round fit with more round things, and to add to that the shape of the eye overall is a dome
- Bugscope TeamHexagons are a good choice because they don't waste any space between them the way circles would.
- Teacherwe will leave the eye and trying to find the thorax.
- Bugscope Teamthe thorax on the moth is covered with setae and scales and is difficult to see
- Teacherthanks for the info.
- Bugscope Teamif the ommatidia were squares, and then you curved the surface, you'd have holes between some of the squares
- Teacherholes would be drafty
- Teacherwe see the dome of the eye really well
- Teacherit looks like the Death Star
- Bugscope Teamno doubt, kinda like that big crack in the compond eye now: yicks!
- Teacherare the spiky things eye lashes?
Bugscope TeamI'm not sure, but an interesting feature of many compound eyes are little hairs (setae) sticking out *between* individual ommatidia. This may serve a protective function like human eyelashes and it also may serve to sense air-currents for navigation
- Teacherwhat is the single spike/needle looking item?on the left of our screen or west.
- Bugscope Teamdifferent setae have different jobs...some help to tase/smell, some to sense movement, etc. I'm not sure what that specific seta's job was
- Bugscope Teamsome also detect changes in the wind
- 9:13 am
- Teachergoing to daddy long leg pollen
- Bugscope Teamcool
- Bugscope Teamoops went by it
- Bugscope Teammary beth, you are doing an excellent job of controlling the microscope. good work!
- Teacherthanks it is hard
- Bugscope Teamnice focus there...
- Bugscope Teamlooks like a leg, but we'd need to zoom out to be sure
- Teacherthanks for the encouragement
- Bugscope Teamwow
- Teacherour thoughts exactly
- Bugscope Teamthis is not so easy to do, and you really are doing a good job navigating
- Bugscope TeamSo yes, that's a leg (two actually, one is partly off screen)
- Teacherwhen daddy long legs loses a leg will it grow back?
Bugscope TeamThere are some insects and animals that can regenerate lost limbs, but I don't know if daddy long legs are one of them
- Bugscope Teamgood thing bugs aren't as big as us, huh? we'd be in big trouble if they were...
Bugscope TeamThe size of insects is actually limited by the physics of their simple breathing systems. It means that even if an insect were to grow huge, it wouldn't be able to breath well enough to sustain itself (kind of relieving, right?). Millions of years ago when there was more oxygen in the air people believe the insects were also larger
- Teacherwhat is the long stringy thing across the page west to east?
Bugscope Teamthats a leg that fell off, and I stuck on the stub
- Bugscope TeamI think they have the capacity to grow back, but usually they don't live that long
- Teacherwhat is this?
- 9:18 am
- Bugscope Teamthere were some seeds that you sent us, this is one I cut in half
- Teacheris this spider spaghetti?
- Bugscope Teamreal spiders can autotomize their legs -- they can jettison a leg that gets bitten so the toxin in the bite does not reach the cephalothorax
- Bugscope TeamAn interesting aside about daddy long legs: Contrary to popular misconception they are not spiders. They are in a different order called Opiliones. They're also known as "harvestmen"
- Bugscope Teamthat was a seed coat
- Bugscope Teamthe spider is now south
- Teacherwe did find that out about daddy long legs
- Bugscope Teammmm, spider spaghetti. with meatballs? (pollen)
- Bugscope Teamsee his legs had fallen off
- Bugscope Teamthey are more like crustaceans
- Teacherwhoa what is this?
- Bugscope Teamthis is the body of the DDL
- Bugscope Teamno i called him daddy "no" legs
- Bugscope TeamDNL
- Teacherlol
- Teacherseatbeltson going in
- Teacheris this near the mouth
- Bugscope Teamthe head is on the top -- we don't get to see it this time
- Bugscope Teammost spiders have a lot more setae then this, i'm wondering if that helps explain why it is in a different category
- Teacherwe know spiders have 2 body parts
- Bugscope Teamyes you can see one of the pincers
- Bugscope Teamto the top right
- Bugscope Teamdaddy long legs usually have an interesting mouth, but the one here seemed deflated somewhat
- 9:23 am
- Teachergoing to the mite
- Teacherthis mite is on a beetle right?
Bugscope Teamthat's right, it's on a beetle that belongs to the same family as the june bug
- Bugscope Teamthere is it's head in the front
- Bugscope Teamyep, you can see the large shell of the mite here.
- Bugscope Teamit looks like it has eyes
- Bugscope Teammites are my favorite insects
- Bugscope TeamTo orient you, the mite looks like a smooth oblong shel and has these little legs sticking out of one end. Otherwise they're pretty featureless
- Teacherwhy are they your favorite Alex?
Bugscope Teamwell, because they are the bugs that bug other bugs! i guess they bug us too, but still, i always laugh when i see i mite on a big old beetle or something like that.
- Bugscope TeamOnce you zoom out it should be easier to see where the beetle stops and mite begins
- Bugscope TeamOh cool, two of them
- Teacherwe see two of them too
- Bugscope TeamNow you start to get a feel for how small they are relative to the beetle, which is already small!
- Teacherwe will laugh too.
- Bugscope Teamthere might even be more in the setae but it's hard to see
- Teacherwhat is this number 487 um?
Bugscope TeamThat's like the distance marking on a map legend. It says that bar is 487 microns (thousandths of a meter) wide. For example human hair is around 60-80 um wide
- Bugscope Teamplus they kinda look like M&M's...don't they?
- Teacheryumm
- Bugscope Team487 um, that is a scale, that means 487 microns. we try to give you a sense of the scale of what you are looking at.
- Bugscope Teamnow it says 1mm = 1 milimeter
- 9:29 am
- Bugscope Teamwe understand some people might not know what a micron is, but it never hurts to hear it for the first time, and maybe learn it. like chas says, a micro is one thousandth of a meter
- Bugscope TeamYou can click on it even to see an expanded list of microscope parameters
- Teacherthanks for this infor.
- Teachergoing to the hornet. seatbelts on
- Bugscope Teamthere are scales all over the body of the hornet
- Teachergetting things into focus here hang on
- Bugscope TeamThis weird looking thing is the end of a leg if you can believe it. The curved part are the two claws
- Teacherwhat do they new with the claws?
- Teachersorry do with the claws
Bugscope TeamThe claws help them attach to things. You can imagine they're great for digging into something like a plant stem
- 9:34 am
- Bugscope Teamoof
- Bugscope TeamHey sorry I am late!!!
- Bugscope TeamYay Annie!
- Teacheroh, this is a good one
- TeacherHi Annie
- Bugscope TeamAnnie is our entomologist.
- Bugscope Teamno problemo annie, mary beth is driving us around, doing a good job of it too.
- TeacherWe are so thankful to have Chas, Annie, Cate, Scott and Alex here helping us.
- Bugscope Teamthis is the beetle foot, right?
Bugscope Teamyes we are on that beetle related to the june bug
- Bugscope Team:)
- Teacheris this the abdomenn behind the leg?
- Bugscope Teamthis is the hornet
- Bugscope TeamI believe we're over the Hornet right now Annie
- Bugscope Teamit is hard to tell from here
- Bugscope Teamheh my bad
- Bugscope Teamhead to the left -- head is to the left I should say
- Teacherthe leg is attached to the thorax
- Bugscope Teamyes
- Teacherneat o la
- Teachershall I go north
- Bugscope Teamthis is a hornet
- Bugscope Teamyes
- Bugscope Teamsure!
- Bugscope Teamlooks like you will want to take the contrast down
- Bugscope Teamits head is a little bright, need to change the contrast
- Bugscope Teamit's all good -- all working
- Bugscope Teamthis is exciting
- 9:39 am
- Teachershould i go minus
- Bugscope Teamwe have the controls set up so that you can make the same mistakes we do
- Bugscope Teamyes you can go to a lower mag
- Bugscope Teamand a little south I think
- Bugscope Teamyou can see the setae sticking out of the top of the head
- Bugscope Teami think mb means minus on the contrast? yes, that should make it darker.
- Bugscope Teamthe hornet has four wigns
- Bugscope Teamwings
- Bugscope Teamhere is the side of the head
- Bugscope Teamthey also have notched eyes
- Bugscope Teamnow we see part of the face
- Bugscope Teamthis is one of the joints of the jaw there
- Bugscope Teamright in the middle
- Teacherwhere is the eye?
- Bugscope TeamThe notch is on the top of the head and we may not be able to see it from this angle
- Bugscope Teamthere is a limb over one of the eyes, like it's too bright
- Bugscope Teamthe hornet's tarsi are over the eye
- Teacherwhat is a tarsi? please
Bugscope TeamTarsi are insect feet
- Teacherwe are going closer
- Bugscope Teamtarsi are the forearm segments
- Bugscope Teamah, now you can see the compound eye, and the facets of it...
- Bugscope Teamthe individual components are tarsomeres
- Bugscope Teamit's really big.
- Bugscope Teamor singular tarsus
- Teacherthere is a lot of good vocabulary
- Bugscope Teamnow you can see the eye, on the left
- Bugscope Teamor a tarsomere!
- Bugscope Teamyou can focus on it
- Teacherthanks for hints
- 9:44 am
- Bugscope Teammb, when focusing, try going one way for a bit, if it doesn't get better, then you need to fucos the other way.
- Bugscope Teamioyu can adjust the focus in little steps
- Teacherwhat is the dark space to the east of the compound eye?
- Bugscope Teamlooks like a socket of some kind?
- Bugscope Teamwe are looking at the edge of the mandible
- Bugscope Teamthat is the jaw
- Teacherthe focus goes automatically until I click done
- Bugscope Teamthe mandible as Annie says
- Teachercan we see the stinger?
Bugscope Teami'm not sure the stinger is very visible, but you can try driving there and looking
- Bugscope Teamthe focus should go in tiny steps, and you look and see where you are
- Bugscope Teamthe stinger is not visible on this one
- Bugscope TeamI looked earlier
- Teacherthanks, going to moth tongue
- Teacherit looks like a cat tongue
- Bugscope Teamwhen you focus, you click plus, then check, plus, then check; if the focus gets worse you click minus, then check, etc.
- Teachermaybe there is nectar on the tongue
- Bugscope Teamit does look scratchy like a cat's tongue
Bugscope Teammy cat furmat licks me all the time, to the point where it hurts and i have to shoo him away...
- Teacherwe see the coiled tongue and the eyes
- Bugscope Teamthe tongue is made to uncoil, and Annie has told us that it operates like one of those coiled paper New Year's noisemakers.
- Bugscope Teamthis is a nice image
- Bugscope Teamgood job driving, again
- 9:49 am
- Bugscope Teami wonder if it makes the same kind of noise, only at a different frequency :p
- Teacherthe tongue works like a straw.
- Bugscope Teamexcept they pump hemolymph (bug blood) into the coild to make it extend
- Teacherwhat color is bug blood?
Bugscope Teamit is clear in all but a few species
- Bugscope Teamgreen
- Teacherhow does it coil back in
Bugscope TeamThe insect stops pumping hemolymph into the coil
- Bugscope Teamit always looks green to me
Bugscope TeamHornworms have green blood...but it is just the pigment from their cuticle.
- Teacherscott do you have your sunglasses on
- Bugscope Teamit must be all of the other stuff
- Teacherthanks for the answers
- Bugscope Teammaybe sunglasses would help, actually
- Bugscope TeamThere are few species of insect with red blood...they have hemoglobin, like we do. These insects live in low-oxygen environments, like poluted streams and deep water.
- TeacherOh, wow about bug blood and polluted areas.okay, we are moving to the hornet hamuli
- Teacherwhat is a hamuli?
Bugscope TeamHamuli are hooks that hold the fore and hind wings of bees and wasps winges together.
- Bugscope TeamI guess when they hit your window it looks yellow sometimes
Bugscope TeamThat's fat body and eggs...which is gross, I know
- Bugscope Teamhamulus means ring
- Teacherwe think it is part of a wing
- Bugscope Teamand the hamuli are little hooks that connect a fore- and hindwing
- Bugscope Teamso that the insect can fly with, essentially, two rather than four wings
- Teacheris the hamuli like a hinge?
- Bugscope Teamnow i will forever be thinking i have fat and eggs on my windshield...
- 9:54 am
- Bugscope Teamgross
- Teachergross is right
- Bugscope TeamMmmmm....I told you it was gross
- Bugscope Teamit is a set of hooks that slides over the second wing edge to make two wings into one
- Bugscope TeamOk everyone. I am sorry that I have to run away. I have class in two minutes!
- Teacherthanks for coming Annie
- Bugscope Teambye bye and thanks for the questions!
- Bugscope Teambye annie and thank you
- Bugscope TeamThanks Annie!
- Teacheris this near the mouth?
- Teacherbye annie,
- Teacherwe think thisis thorax
- Bugscope TeamNow you will have to take what I say with a grain of salt -- Annie is not hear to correct me.
- Bugscope Teamthis is the thorax
- Teacherwe have to be going as well, our last comments
- TeacherThis was incredible. Thank you for taking time to talk with us.
- TeacherCan we visit any time on our homepage? CAn we email you questions?
Bugscope Teamyes! your homepage is: http://bugscope.itg.uiuc.edu/members/2007-065
- Bugscope TeamPlease come back next year.
- TeacherCan we go on this site from home?
Bugscope TeamThe live interface is only open during a session, but you can visit your member's homepage from anywhere
- TeacherWe will come back next year.
- Bugscope TeamCertainly you may ask us questions. bugscope@itg.uiuc.edu
- TeacherCan we view the presets on our own?
- Bugscope TeamYou can indeed reach your page from home -- from any browser.
- TeacherClapping and saying thanks!!!
- Bugscope TeamYay!
- Bugscope Teamthank you mary beth, great session.
- TeacherBye now. Thanks again. This was terrific
- Bugscope Teami'm glad you all had fun
- Bugscope Teamwe had a lot of fun as well
- Bugscope Teamremember, mites look like M&M's, but they don't taste like them!
- Teacherwe will remember, good advice
- Bugscope TeamThanks for the great session MB!
- Bugscope Team;)
- Bugscope TeamRe: homepage, this is an excellent question. Through your homepage, you can access all your images. If you make a presentation to your colleagues at your school, then your homepage (Bugscope session) can serve as a good discussion starting point.
- Teacherlogging out bye
- Bugscope Teamchow!
- 10:00 am
- Bugscope TeamCiao.
- Bugscope TeamThanks, MB, for your participation. Please do not hesitate to share your insights about your session with us. Stay in touch.
- Bugscope TeamHey, Chas, Bugscope Guru, a question. Any way to find out the guest location? Well, later next week. Take care.
- Bugscope Teami'm going to close the session....
- Bugscope Teamare we all ready to logoff
- Bugscope Teamrxl stopped, session disabled. good session everyone. over and out.
