• 10:00 am
• Bugscope TeamScott, You can ignore that email that I just sent you...although it was still telling me that there is no active session
• Bugscope TeamI am going to go make some tea...I will be right back!!!!
• Bugscope TeamAnnie is beside herself. Just wait 'til she starts drinking tea.
• Bugscope TeamHi Linda!
• Bugscope TeamLinda the star next to your name, on the left there, indicates that you have control of the microscope.
• Bugscope TeamYou can drive, choose presets, change focus, change brightness and magnification -- whatever you would like.
• Bugscope TeamAnnie, Chas, and I are here to help any way we can.
• 10:05 am
• Bugscope TeamHi Judy!
• Bugscope TeamWelcome to bugscope.
• StudentHi
• StudentI am actually a teacher... signed in to wrong field... sorry!
• Bugscope TeamYou could log out and log back in if you would like.
• StudentWe actually don' t know how to start...
• StudentNo controls on screen
• Bugscope TeamThey should show up soon
• StudentOK, Thanks
• Bugscope TeamWe only give them to one client at a time, and they were on the "Linda" login
• StudentI'' log out
• StudentNeither of us do
• Bugscope TeamYou can see the curvy tenent setae on the ladybug's pulvillus now. The pulvillus is the pad on the tarsus -- on the forearm -- that helps the ladybug stick to walls, etc.
• TeacherI am Linda. Where are the controlls?
• Bugscope TeamThey should be back real soon? See them yet?
• Bugscope Teami am back
• Bugscope TeamLinda you should be able to see the control on the upper right side of the screen.
• Bugscope TeamAnd you should be able to see the presets to the right of this chat text.
• Bugscope TeamGreat.
• 10:10 am
• Bugscope TeamPlease try changing mag or selecting a preset.
• Bugscope TeamAnnie this is the ladybug just now.
• Bugscope TeamJudy: it's doesn't affect the way things run, but if you want to be on as a teacher, when you logout, there's a link that says "Not a student? Log in" that you can click, then you can choose Teacher from the drop-down list
• Bugscope TeamJudy as a student you do not have control unless someone gives it to you.
• Bugscope TeamOK, you're driving. Now click inside the image somewhere

• Bugscope TeamIf you click inside the image, it will start driving in that direction
• Bugscope TeamThen you click again to stop.
• Bugscope TeamLinda let us know if you need any help. We can also phone if that works better for you.
• Bugscope TeamAlternatively, you can use the "click to center" button instead and it will move the stage so that what you clicked on is in the center of the field of view (so that you can zoom in on it)

• Bugscope TeamDo you have students with you now? Does anyone have questions?

• Bugscope TeamYou have a lot of options for control, and I imagine also it's hard to concentrate with us writing all these messages to you.
• TeacherWhat are we looking at right now?
• Bugscope Teami can't tell where we are, you could try to lower the mag some
• 10:15 am

• Bugscope TeamThis is the edge of the pad on the ladybug tarsus, I think.

• Bugscope TeamCool!

• Bugscope Teamawesome one too!
• Bugscope TeamNow you can see the face, above.

• Bugscope TeamNice.
• Bugscope TeamLinda and Judy Chas is impressed with your driving.
• Bugscope Teamgreat job driving Linda!

• Bugscope TeamThis is another tarsus.
• Bugscope TeamAnd two pulvilli.
• Bugscope TeamThe pad that has the sticky setae on it.
• Bugscope TeamThere's some great details if you zoom in on the pulvillus there
• Bugscope Teamsingular is pulvillus.

• Bugscope TeamChas beat me to it, of course.
• Bugscope TeamI am here
• Bugscope TeamI have been here :P

• Bugscope TeamI just read the comment about tea
• Bugscope Team--I am here, but behing
• Bugscope Teambehinnd
• 10:20 am
• Bugscope TeamYou are charged up, looks like.

• Bugscope TeamLinda, Judy: If the students have any questions you can relay them to us; we've got an entomologist logged on who almost certainly knows the answers!

• Bugscope Teama little bit...my throat is scratchy
• Bugscope Teamthus the tea
• Bugscope Teamwe have lots of presets you can look at today
• Bugscope TeamAnnie if you can communicate with the guy who's providing samples for Thurs or Friday, I forget which, please let him know we'll need to have them dry.
• Bugscope Team~??
• TeacherWhy does the lady bug need the sticky pads?
• Bugscope TeamThe lady bug needs little hairs to help it hang on to trees, leaves and other places where it walks

• Bugscope TeamThe pads help it stick wherever it wants as it feasts on other bugs.

• Bugscope TeamThey need to hold on because wind and rain are pretty powerful forces when you are a tiny little insect
• Bugscope TeamNow we are looking at the little sensory setae on the eye of a fruit fly.
• 10:26 am
• Bugscope TeamWhen they bend in the wind the fruit fly gets info about wind speed and , direction, ...

• Bugscope Teamoops.
• Bugscope TeamNow we see the fruit fly head on.

• Bugscope TeamGreat Job driving!
• Bugscope TeamThis is the antenna, in about the middle of the screen, plus the little tree shaped part.
• Bugscope Teamthat fleshy fingerlike object near...d'oh!
• TeacherThanks.

• Bugscope TeamThis is a haltere.

• Bugscope Teamflies have only two sets of big wings. Their hind wings are reduced into halteres
• Bugscope TeamThe haltere balances the movement of the wing. Sort of like a gyroscope to keep a two-winged insect steady in the air.

• Bugscope TeamYou see them bouncing back and forth against the body, so they're in constant motion
• 10:31 am
• Bugscope TeamThat's what gives them the gyroscopic capabilities
• TeacherThank you again!

• Bugscope TeamNow we're looking at the edge of a wing, and the tape, and now the head of a millipede.

• Bugscope TeamYou can see the eye, as little bumps.
• Bugscope TeamThe compound eye is not nearly as well deveo
• Bugscope Teamwell on the screen they look big right now :p
• Bugscope Teamdeveloped as that of a flying insect.
• Bugscope Teamfrom the scale bar at the lower left we see they're about 30 microns, or about half the width of a human hair

• 10:36 am
• Bugscope TeamThis is the millipede (thousand-foot)
• TeacherHow many legs does this insect have?
• Bugscope Team76
• Bugscope Teamcan't say for sure, but you could estimate by zooming in and counting a section of them, then multiplying by the length there
• Bugscope Teamdid you really count them?
• Bugscope TeamWe don't know, really.

• Bugscope Teamthis is the edge of one of your fly wings
• Bugscope Teamhairy wings

• Bugscope TeamThese are the analogous structures to what we had seen on the ladybug pulvillus.

• Bugscope Teamno eye setae
• Bugscope Teamthis is the compound eye of one of the flies you sent us
• Bugscope TeamNow the fly compound eye. Note that it does not (D'Oh!) have setae, or not many of them.
• Bugscope Teamsometimes they'll have little setae sticking up out of the eye between some of the facets (right in the corners where three of them meet)
• Bugscope TeamTo the upper left there was a single seta, off screen now.
• 10:42 am

• Bugscope Teamthis is the fly tongue

• Bugscope Teamyou can see it's mouth is kind of dirty
• Bugscope TeamTons of setae, including some really big ones. One eye is visible on the far left there
• Bugscope Teamthe antennae are in the dark area at the top of the head

• Bugscope TeamCool, you're honing in on the compound eye there

• Bugscope TeamIt could use some focussing now to sharpen it up
• Bugscope Teamnice job, you could even go a little further maybe
• TeacherHow many lenses are in their compound eyes?
  Bugscope TeamThe number varies dramatically with insect type. In some sub-terranian ants I'd guess 30-40, in some flying insects probably many hundreds
• 10:47 am
• Bugscope TeamThat is a hard question...it depends upon the insect
• Bugscope Teamoop

• Bugscope Teamin fruit flies there are more than 700 per eye
• Bugscope Teamnot only the number, but the surface texture and complexity varies as a function of how important vision is to the insect
• Bugscope TeamI just looked that up
• Bugscope Teamwow, and fruit flies are TINY, so that's not a lot of room to pack them all in

• Bugscope Teamcentipede?

• Bugscope TeamYeah, the antenna on it I think, or maybe the tail?

• Bugscope TeamNow we're at the ant. You can see the mandibles (jaws) prominent at the middle of the screen there
• Bugscope TeamBecause the insects have exo-skeletons, hard cuticle as their skin instead of bones, we can see these really interesting joints where all the moving parts of the insect hinge
• 10:54 am

• Bugscope TeamThe mouth!

• Bugscope TeamAnts often appear to have a second creature in their mouths.
• Bugscope TeamWith all of the accessory mouthparts.
• TeacherThis is wonderful!

• Bugscope TeamAh, a claw!

• Bugscope TeamYou are doing a GREAT JOB with driving the scope!
• Bugscope TeamYou are really doing a great job navigating. This is the kind of session we like to see. It doesn't happen often.
• Bugscope TeamD'Oh!
• TeacherThank you!

• Bugscope TeamThis could use some focussing
• TeacherDo they use the claws to dig underground?

• Bugscope Teamthey use the claws to hold on to the places where they walk

• Bugscope Teamusually when an insect has legs designed for digging their legs look more like shovels
• 11:00 am
• Bugscope TeamA lot of times the larva, young insects, will be burrowers who live underground
• Bugscope TeamBut then as they mature they come out of the ground
• TeacherThank you very much for this experience!
• Bugscope TeamYou are very welcome.
• Bugscope TeamJust let us know when you're done so we can wrap things up here. We can go for another few minutes if you'd like
• Bugscope Teamwe enjoy doing this!
• Bugscope TeamWe're glad to have you on! You did a great job exploring the sample stage
• TeacherWe can stay on for a few more minutes.
• Bugscope TeamSure, no problemo.

• 11:05 am
• Bugscope Teamthis is cool

• Bugscope TeamIt's amazing to see how all the short tubular sections of the centipede interlock like that
• TeacherThank you again!
• Bugscope TeamGuys, I have to bow out for now
• Bugscope TeamThanks a bunch!
• Bugscope TeamCya annie, thanks for the great answers
• Bugscope TeamLinda - glad to have you on again
• Bugscope TeamOkay Annie, we can finish up, thanks for your awesome help!
• Bugscope Teamif you want to see the transcript & images: http://discord.itg.uiuc.edu/bugscope/chat_transcript.php?proposal=2007-021
• Bugscope Teamciao!
• Bugscope TeamWe're going to start shutting things down here if that's OK
• TeacherYes!
• 11:10 am
• Bugscope TeamOkay, I'm logging off now. See you all at 11:30.
• 3:23 pm
