- Bugscope Teamhi skyla, welcome to bugscope!
- TeacherAre we in control? I don't see any control devices?!?!?!
- Bugscope Teami just unlocked the session now, so you should see controls...
- TeacherThe picturs are changing, but we're not doing anything. COnfused!
- Bugscope Teamgot em?
- Bugscope Teamscott is driving the scope, sorry
- Bugscope Teamok, one thing at a time, to the right of the image, do you see the controls? Magnify? NAvigation? Focus? etc.?
- Bugscope Teamscott is done driving now
- Bugscope Teamif you don't see the controls, try expanding your browser window
- Bugscope Teamalso, bugscope requires at leat 1024x768 resolution
- Bugscope TeamI was trying, as I often do, to get one last preset. This is the stinger of the yellowjacket you sent. It is super small, does not look so good, but there it is.
- Bugscope TeamYou can see that it is charging up with electrons.
- StudentI've expanded the screen, and still nothing. ANy advice?
Bugscope TeamOnly the login Skyla will have control, unless we give it to Hannah.'
- Bugscope TeamHi Hannah!
- 4:32 pm
- Bugscope TeamOn the Skyla computer you should see controls along the top right of the window.
- Bugscope TeamDo you want us to give control to Hannah?
- StudentWe're only on one computer, but it logged us out and told us that skyla was already on-line. Can we chane Hannah to admin?
- Bugscope Teami just gave control to Hannah
- Bugscope TeamYeah Alex just set you up.
- StudentShoud we be seeing controls?
- Bugscope TeamYes definitely.
- Bugscope Teamok, i just logged off skyla, try logging out, and login again as teacher, with the name skyla, or any other name you want
- Bugscope TeamDo you see nothing to the right of the image?
- Studentthe image goes all the way to the right hand side of the screen
Bugscope Teamyour screen resolution is probably set too low
- StudentI don't see a logout button either. Ae we blowing this?
- Bugscope Teamdo you know how to change your screen resolution?
- Bugscope TeamAlex can tell you how to fix it. We should be good soon.
- StudentYes. We just did. I'll try again.
- Bugscope Teamyou are doing fine hannah, hang in there, we'll get you working
- Bugscope Teamscreen res should be 1280x1024, or 1024768 at the lowest
- StudentWe go 'em! Yay!
- Bugscope Team:)
- Bugscope TeamYay!
- Bugscope Teamthis is cool
- StudentWhat bug is this?
- Bugscope Teamthis is the yellowjacket
- 4:37 pm
- Bugscope Teamits antenna
- Bugscope Teamthisis a wasp, a jellow-jacket wasp
- Bugscope Teamsee the compound eye
- Bugscope Teamand the jaws?
- StudentYes! Very cool!
- StudentWE want to know how it is that the first geeration bees laid by the quee are all female.
- Bugscope TeamMay be because the queen has not mated and is reproducing parthenogenically.
- Studentwhat is parthengenically/
- Bugscope TeamWorker bees are female; drones are male. Only the females have stingers, which are modified ovipositors.
- Bugscope Teamsome lizards can reproduce that way as well. They have only half the chromosome complement because they did not have a mate to contribute the other half.
- StudentWe can't get back to our preset image? Should we just be able to click on it?
- 4:42 pm
- Bugscope Teamany preset can be clicked on and it'll take you there
- Bugscope Teamtry refreshing the page if clicking doesn't work
- Bugscope Teamrefresh with F5
- Bugscope TeamParthenogenesis (from the Greek παρθένος parthenos, "virgin", + γένεσις genesis, "creation") is a form of asexual reproduction found in females, where growth and development of embryos occurs without fertilization by a male. In plants, parthenogenesis means development of an embryo from an unfertilized egg cell, and is a component process of apomixis. The offspring produced by parthenogenesis are always female in species that use the XY sex-determination system.
- Bugscope Teamthat was copied from Wikipedia.
- Bugscope Teamlet me know if that doesn't work, i can take you to a preset, and that might fix it
- StudentCan you take us to the preset of the rolly polly/
- Bugscope Teamok, there's a problem
- Bugscope Teamlet's try something...
- Studentwhat is it?
- Bugscope Teamwe'll get it
- Bugscope Teamin your controls, does your navigation give you two button, click to drive and click to center?
- Bugscope Teamwe are working on it
- Studentthank you!
- StudentWE red that they are monogomous. Are many bugs that way?
- Bugscope Teamwhen using "click to drive", make sure to click to start driving, but also, very important, you must click again to stop moving
- 4:47 pm
- Bugscope TeamThe queen bee can fly, and she is said to go far from the hive when she wants to mate to ensure that she is mating with new genetic stock.
- Studenthaha! How many times do rolly pollies lay eggs?
- Studentare those hairs?
Bugscope Teamthose are little sensory spines.
- Bugscope TeamRoly polies of course are not insects. They are isopods, and they have more than six legs.
- Studentare they still bugs?
Bugscope TeamTechnically they are not bugs. True bugs are insects, but only certain insects are true bugs. The stinkbug and the assassin bug on today's sample stub are true bugs.
- Bugscope Teaminsects do have lots of hairs on them, but they aren't called hairs, they are setae. (see-tee) setae help insects to sense their environment
- Bugscope Teamnice job driving!
- StudentSo what is a rolly pollie then?
Bugscope Teamit is a crustacean
- 4:52 pm
- Bugscope Teamheh, yeah, cool huh?
- Bugscope TeamYes they are crustaceans, as Alex says, and they are supposed to have gill-like structures but I am not sure we have ever seen them.
- Bugscope Teammore technically, it is called a terrestrial crustacean
- Bugscope TeamHey, I am late!!!
- StudentHi annie! We're tryiing to get to the stinger.
- Bugscope TeamGood luck!
- Bugscope Teamthe stinger is where we started, and it did not look very good so I didn't make it into a preset. It is south and west of here.
- StudentSensory spines? or hair?
Bugscope TeamWe often call the little hairs setae, or spines or bristles or trichae or microsetae...
- Bugscope TeamIf you take the mag as low as it will go and drive to the south and west...
- Bugscope TeamOr I can drive you there. I can get there using the microscope itself.
- StudentTakeus there!
- Bugscope Teamscott is on it
- StudentThat's so tiny!
- StudentIs there venom in it? How does that hurt s much?
Bugscope TeamThe venom causes a kind of allergic reaction that causes the site of the sting to swell and burn
- 4:58 pm
- Bugscope TeamThe venom is in a sac at the base of the stinger, it is hidden inside the body
- Bugscope Teamsome of the setae are touch receptors, some are smell receptors, some are hot-cold sensory...
- Bugscope Teamsee the stinger is coming out only maybe 100 microns -- a tenth of a millimeter.
- Studenthow much of the stinger is inside the body? What percentage are we seeing?
Bugscope TeamI would say we can see about 1/3 of the whole stinger
- Bugscope Teamyou can see that the brightness settings for the stinger kicked everything up here.
- StudentDid we send you a fly too? I don't see it in the presets
Bugscope TeamThere are a bunch of flies on the stage. The third insect you sent we newer found.
- Bugscope Teampresets 6, 9 and 10 are some kind of fly's and such
- Bugscope Teammaybe preset 11 is a fly too, a haltere is always found on some kind of flying insect i think
- 5:03 pm
- Bugscope Teama haltere is always found on Diptera, which are flies. di means two, and ptera means wing
- Bugscope Teamthe halteres balance the motion of the wings; halteres are like counterbalances.
- Studentis that a toungue?
Bugscope Teamthat is its probscis
- Bugscope Teamthis is the head of the assassin bug, a true bug
- Bugscope Teamproboscis
- Bugscope Teamsorry
- Bugscope TeamThat is the whole mouth
- Studentwhy is it an assasin?
Bugscope TeamThey sneak up on their prey (other insects and even spiders) and they catch them and eat them!
- Bugscope Teamthe largest proboscis in the world is found on a elephant! the elephant trunk is also a proboscis
- Studentwhat do flies eat?
Bugscope Teama lot of them have spongy mouthparts and sop up their food. they spit out digestive juices and then sop up what they want -- like nectar, juice, sweet stuff.
- Bugscope Teamthey have spines on the inner surfaces of their arms that let them hold their prey tightly
- Bugscope Teamsort of like praying mantises
- Studenthairy tongue?
Bugscope Teama lot of the setae (hairs) are chemosensory setae, that means they can smell and taste with them
- 5:09 pm
- Bugscope Teambut not all flies have sponging mouthparts. some have slashing mouthparts -- like deerflies or horseflies. and they drink blood.
- Bugscope Teambacteria to the upper right
- Bugscope TeamBut there are as many flies that eat different kinds of foods as there are foods. Flies will eat living plants, blood, dead bodies, animal waste, other insects, fungus, pollen. Flies, as an order, are very diverse.
- StudentDo they ee one image or a bunch?
Bugscope Teamthey process the images into a coherent whole, we think. if you had compound eyes like a dragonfly, or like a bee, you would have better peripheral vision.
- Bugscope Teamtake the mag down and you can see that this aphid was clinging to a fruit fly
- Bugscope Teamsee it was lying upside down on the fly
- Bugscope Teamcool, you can see off the edge of the stage now
- Bugscope Teamalso if you had compound eyes you would be able to sense motion better than we do -- you would get better updates of things moving near you.
- Bugscope Teambut you might be funny looking if you had compound eyes. people might not talk to you.
- StudentWhy don't roaches die easily?
Bugscope TeamWell, they die quite easily if you step on them. It is difficult to get rid of them if you have an infestation because they hide and they move around a lot and there are usually so many of them.
- 5:15 pm
- StudentDo bees really die after they sting you
Bugscope Teamhoneybees do.
- Bugscope Teamthis is cool. salt from a Wendy's restaurant.
- Bugscope Teamwhen they sting you the stinger comes out, plus the gland with the venom, which works like a little outboard motor to pump all of the venom into your skin.
- Studentyellow jackets don't?
Bugscope TeamThey don't necessarily...usually when I get stung I smash the yellowjacket and she doesn't get away alive!
- Bugscope Teamso the bee has made a big hole in the end of its abdomen and can't live after that.
- Bugscope Teamyellow jackets can keep stinging, I think. they're not bees
- StudentHow do butterflies protect themselves?
Bugscope Teambutterflies often taste bad, and that is a good defense. also, they can shed scales, for example if they fly into a spider web. that allows them to slip away
- StudentWhat's the exact definition of bee, then?
Bugscope TeamA bee is a type of wasp in the family Apidae. Technically, they are separated by having forked hairs all over their bodies. Many bees are social, and most feed on pollen and nectar (they are usually vegetarians).
- 5:20 pm
- Bugscope Teamthere is something on the web telling you how to get a yellowjacket sting out of your skin. I think they are mistaken.
- Bugscope TeamAnnie is an entomologist.
- Bugscope Teama cool fact about butterfly's is that some of the species migrate long distances. the monarch butterfly migrates 3000 miles (Mexico to Canada)
- Bugscope Teamsome spiders will cut butterflies out of their webs because they don't want them
- Bugscope Teamspiders eat by injecting venom into their prey. the venom digests the insides of the victims, and the spiders suck that back out like a milkshake. they don't chew and would not like scales anyway.
- StudentWe're out of time time on our end! Thank you for all of your help!
- Bugscope TeamOh.
- Bugscope TeamThank You!
- Bugscope TeamSee you next time!
- Bugscope Teamdon't forget, ALL the chat and images from this sessions are saved to you member page: http://bugscope.beckman.illinois.edu/members/2009-114
- 5:25 pm
- Studentthank you so much! This was very cool once we ironed out the technical details!
- Bugscope Team:)
- Bugscope TeamThank you all!!
- StudentWe want your jobs when we gro up
- Bugscope Teamthis is fun but it is not all we do.
- Bugscope TeamHahaha! I am trying to find a permanent job, I just graduated in May.
- Bugscope Teamthis is the most fun, but we get to see some pretty cool research as well.
- Bugscope TeamAnnie got her PhD here and logged on today from her place in California.
- StudentDad is a scientist. We totally get that!
- Bugscope TeamWe're in Illinois, 23 feet underground, in Urbana-Champaign.
- StudentDad graduated in November 08 and now we're stuck in UT becasue that's the only place he could find a job. Good luck!
- Bugscope TeamI completely understand that!
- StudentBye guys! Good luck Annie!
- Bugscope Teamlater hannah
- Bugscope TeamThank you!
- Bugscope TeamBye bye thank you!
