- 6:42 pm
- Bugscope Teammaking presets

- 7:05 pm
- Bugscope TeamDone with setup and ready to roll. Unlocked the controls.
- 7:25 pm
- Bugscope Teamhello!
- Bugscope TeamWelcome to Bugscope!
- TeacherHey - we are getting ready to chat soon! Michele
- Bugscope Teamcool
- TeacherI am going to re oad and go onto Firefox
- Bugscope Teamcool
- 7:31 pm
- Bugscope TeamHello opy!
- 7:37 pm
- Bugscope TeamMichele we had a guest but he bailed out quickly.
- Bugscope Teamthis is the abdomen of the honeybee
- TeacherOK -here we are! What are we looking at?
- Bugscope Teamstinger is hard to see
- Bugscope Teamwe are on the honeybee
- Bugscope Teamyou sent us some nice bugs
- TeacherWhat are the "hairs" called and what do they do?
Bugscope Teamthe hairs are setae (as scott said) and they are there to help the insects feel what's going on around them or help them do things. Bees have lots of hairs where some will help collect pollen
- Bugscope Teamsetae
- Bugscope Teamlots of scales from other insects, like the moth, mostly
- TeacherWhat are the hooks for on the feet?
Bugscope Teamthe hooks are claws. Claws can be found at the end of each leg. They help the insect grab onto things or to cling to things. I think almost all insects have claws
- 7:42 pm
- Bugscope Teamthese are tarsi -- the last several arm/leg segments
- TeacherThey grow the insects HUGE in CA!!
- Bugscope Teamthe claws open and close kind of like one of those tools you can use to reach a can on a tall shelf -- there is a tendon inside the tarsus called an unguitractor that opens and closes the claw
- Bugscope TeamYeah not quite the same little insects they have up here
- Bugscope Teamyeah I kind of like living in a place where the bugs die in the winter
- Bugscope Teamexcept they crawl in our houses to try to wait winter out
- TeacherIS the stinger intact?
Bugscope Teamyes it is preset 18
- Bugscope Teamthat smooth area is where the worker bee packs the pollen/nectar
- Bugscope Teamand then take the mag down so you can see it better
- TeacherDoes the bee die right after it stings someone?
Bugscope Teampretty quickly. it loses its stinger and the venom gland, and that leaves a big hole in its body
- 7:47 pm
- TeacherHey - side teacher question = if we did not know how to find a certain part on the insect, could you "drive" the ESEM for us? Just a teacher thought..
Bugscope Teamsure. we do that often
- Bugscope Teamthey only die when they sting a mammal. The stinger won't stick in other things usually
- Bugscope Teamthe stinger has recurved spines and doesn't come out easily once it's in
- Bugscope Teamyou can start to see it now, on the left of that curved scale
- Bugscope Teamthis is one of the few insects besides moths and butterflies that has scales
- Bugscope Teamthe scales reflect silver light
- Teacheris it laying on its back?
Bugscope Teammost thing we put on the stub we will mount on their back because they are more interesting from this view.
- Bugscope Teamsome weevils also have scales, as do mosquitos
- TeacherIs that the head?
- Bugscope Teamyou can see why I didn't have a preset of the head
- Bugscope Teamsomething vile happened to it
- 7:52 pm
- Teacherit looks like its hollow
Bugscope Teampretty dried out, but still kind of neat to see the scales
- Bugscope Teamthey have funny-looking faces. too bad we didn't get to see it
- Teachervery cool!!!
- Bugscope Teamin the background we see carbon doublestick tape
- Bugscope Teamalso, if you click on the micron bar you can see the 'scope parameters. then click on the bar again to make them go away
- Bugscope Teamthe samples are all coated with gold-palladium to make them conductive, and most of the critters are mounted on silver paint for the same reason
- Bugscope Teamthere are tenent setae on this pad of setae
- Bugscope Teamnow you can see that the tenent setae are sticky
- Bugscope Teamthere's a scale stuck to them
- Bugscope Teamtenent setae act like suction cups or velcro where they stick to walls helping the insect walk on walls
- Bugscope Teamthe pad is called a pulvillus
- TeacherHow many claws do they have on each leg?
Bugscope Teamusually a matched pair of claws. sometimes the claws will be asymmetric, and sometimes one will have extra 'hooks' or spines
- 7:58 pm
- Bugscope Teamif you look at one of the spider's claws, you can see that it is a little different
- TeacherHow many varieties of flies are there?
Bugscope Teamthere are said to be about 6500 fly species
- Bugscope Teamand isopods have single pointy little claw feet
- Bugscope Teamthis is a female, we think
- TeacherAre we looking at the eyes here? Is it true that bug eyes are really many little eyes or are they just two eyeballs
- Teacher(compound eyes?)
- Bugscope Teambecause male fly eyes are often close together
- Teacherthat's a lot of flies! is there an easy way to tell which species it is just by looking at it with the naked eye?
- Bugscope Teammany flying insects such as wasps and bees have five eyes -- two compound eyes and three simple eyes called ocelli
- Teacheris that bacteria in the eye?!
Bugscope TeamI am sorry I didn't see it but I don't think so.
- Bugscope TeamI was wrong about the number of fly species -- it is much higher, but we cannot find a reliable number
- 8:03 pm
- TeacherWhat actually is the wild thing and where do they live?
- Bugscope Teamhere is a critter with eight eyes
- Bugscope Teamthis spider we mounted so we could see the eyes
- Bugscope Team8 eyes and 8 legs
- Bugscope Teamapparently they live in Cali, and this is a small one you sent
- Bugscope Teamsome can see fairly well, but many cannot and rely much more on their ability to sense vibration
- Bugscope Teamtheir setae probably help them feel the vibrations.
- TeacherWhat am I zoomed in on right now?
Bugscope Teamthis is the top of the abdomen
- Bugscope Teamspiders use their fangs to inject venom into their prey
- Bugscope Teamwhen they dry out the abdomen sinks in a little
- Bugscope Teamthe venom dissolves the internal components of the prey, and the spider sucks it all up like a milkshake
- Bugscope Teamthat is where the spinnerets are but does not have a lot of detail I could recognize earlier
- TeacherIs this the spinneret?
- 8:08 pm
- Bugscope Teamthere should be four little turrets there, the spinnerets, but they are hard to distinguish on this sample
- Bugscope Teami think so.
- Bugscope Teamsome web is not sticky
- Bugscope Teamalso, spiders can recycle their web by eating it
- Bugscope Teamthis is the longest haltere we have seen that I can recall
- Bugscope Teamabout 1.5 mm
- Bugscope Teamyou can see a spiracle at its proximal end
- TeacherHow do we get back to the chat after the session
- Bugscope Teamthe punching bag part is to the left and shrunken
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2009-126/
- Bugscope Teamthere is a link on your member page that allows you to see the transcript with the images
- Bugscope Teamyou have to log in to see it not anonymized
- TeacherWhat is in the center of the screen?
Bugscope Teamthe head is in the middle. It has a giant compound eye staring at us
- Bugscope Teamwe had to start anonymizing it a few years ago when some guy tracked down his ex-wife using Bugscope
- Bugscope Teameye of the damselfly
- 8:14 pm
- Bugscope Teamlots and lots of ommatidia for some unfortunate grad student to count
- Bugscope Teamthere you go -- deus ex machina
- Bugscope Teamthe ommatidia shrink a bit when the eye dries out as well
- TeacherWhy are there gaps between the lenses?
- Bugscope Teamnormally, in life, they would be swollen, as Cate says, no gaps
- Bugscope Teammosquito eyes are much like this as well
- TeacherThanks
- TeacherThis is Michele Korb again - we are signing off! Thank you! I will see you in the next two sessions!
- Bugscope TeamThank you for joining us for another bugscope session
