- 6:19pm
- Bugscope Team pumping down
- 6:35pm
- 6:42pm
- Bugscope Team making presets
- 6:48pm
- 6:54pm
- 6:59pm
- 7:05pm
- Bugscope Team Done with setup and ready to roll. Unlocked the controls.
- 7:25pm
- Bugscope Team hello!
- Bugscope Team Welcome to Bugscope!
- Teacher Hey - we are getting ready to chat soon! Michele
- Bugscope Team cool
- Teacher I am going to re oad and go onto Firefox
- Bugscope Team cool
- 7:31pm
- Bugscope Team Hello opy!
- 7:37pm
- Bugscope Team Michele we had a guest but he bailed out quickly.
- Bugscope Team this is the abdomen of the honeybee
- Teacher OK -here we are! What are we looking at?
- Bugscope Team stinger is hard to see
- Bugscope Team we are on the honeybee
- Bugscope Team you sent us some nice bugs
- Teacher What are the "hairs" called and what do they do?
Bugscope Team the 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 Team setae
- Bugscope Team lots of scales from other insects, like the moth, mostly
- Teacher What are the hooks for on the feet?
Bugscope Team the 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
- 7:42pm
- Bugscope Team these are tarsi -- the last several arm/leg segments
- Teacher They grow the insects HUGE in CA!!
- Bugscope Team the 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 Team Yeah not quite the same little insects they have up here
- Bugscope Team yeah I kind of like living in a place where the bugs die in the winter
- Bugscope Team except they crawl in our houses to try to wait winter out
- Teacher IS the stinger intact?
Bugscope Team yes it is preset 18
- Bugscope Team that smooth area is where the worker bee packs the pollen/nectar
- Bugscope Team and then take the mag down so you can see it better
- Teacher Does the bee die right after it stings someone?
Bugscope Team pretty quickly. it loses its stinger and the venom gland, and that leaves a big hole in its body
- 7:47pm
- Teacher Hey - 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 Team sure. we do that often
- Bugscope Team they only die when they sting a mammal. The stinger won't stick in other things usually
- Bugscope Team the stinger has recurved spines and doesn't come out easily once it's in
- Bugscope Team you can start to see it now, on the left of that curved scale
- Bugscope Team this is one of the few insects besides moths and butterflies that has scales
- Bugscope Team the scales reflect silver light
- Teacher is it laying on its back?
Bugscope Team most thing we put on the stub we will mount on their back because they are more interesting from this view.
- Bugscope Team some weevils also have scales, as do mosquitos
- Teacher Is that the head?
- Bugscope Team you can see why I didn't have a preset of the head
- Bugscope Team something vile happened to it
- 7:52pm
- Teacher it looks like its hollow
Bugscope Team pretty dried out, but still kind of neat to see the scales
- Bugscope Team they have funny-looking faces. too bad we didn't get to see it
- Teacher very cool!!!
- Bugscope Team in the background we see carbon doublestick tape
- Bugscope Team also, 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 Team the 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 Team there are tenent setae on this pad of setae
- Bugscope Team now you can see that the tenent setae are sticky
- Bugscope Team there's a scale stuck to them
- Bugscope Team tenent setae act like suction cups or velcro where they stick to walls helping the insect walk on walls
- Bugscope Team the pad is called a pulvillus
- Teacher How many claws do they have on each leg?
Bugscope Team usually a matched pair of claws. sometimes the claws will be asymmetric, and sometimes one will have extra 'hooks' or spines
- 7:58pm
- Bugscope Team if you look at one of the spider's claws, you can see that it is a little different
- Teacher How many varieties of flies are there?
Bugscope Team there are said to be about 6500 fly species
- Bugscope Team and isopods have single pointy little claw feet
- Bugscope Team this is a female, we think
- Teacher Are 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 Team because male fly eyes are often close together
- Teacher that'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 Team many flying insects such as wasps and bees have five eyes -- two compound eyes and three simple eyes called ocelli
- Teacher is that bacteria in the eye?!
Bugscope Team I am sorry I didn't see it but I don't think so.
- Bugscope Team I was wrong about the number of fly species -- it is much higher, but we cannot find a reliable number
- 8:03pm
- Teacher What actually is the wild thing and where do they live?
- Bugscope Team here is a critter with eight eyes
- Bugscope Team this spider we mounted so we could see the eyes
- Bugscope Team 8 eyes and 8 legs
- Bugscope Team apparently they live in Cali, and this is a small one you sent
- Bugscope Team some can see fairly well, but many cannot and rely much more on their ability to sense vibration
- Bugscope Team their setae probably help them feel the vibrations.
- Teacher What am I zoomed in on right now?
Bugscope Team this is the top of the abdomen
- Bugscope Team spiders use their fangs to inject venom into their prey
- Bugscope Team when they dry out the abdomen sinks in a little
- Bugscope Team the venom dissolves the internal components of the prey, and the spider sucks it all up like a milkshake
- Bugscope Team that is where the spinnerets are but does not have a lot of detail I could recognize earlier
- Teacher Is this the spinneret?
- 8:08pm
- Bugscope Team there should be four little turrets there, the spinnerets, but they are hard to distinguish on this sample
- Bugscope Team i think so.
- Bugscope Team some web is not sticky
- Bugscope Team also, spiders can recycle their web by eating it
- Bugscope Team this is the longest haltere we have seen that I can recall
- Bugscope Team about 1.5 mm
- Bugscope Team you can see a spiracle at its proximal end
- Teacher How do we get back to the chat after the session
- Bugscope Team the punching bag part is to the left and shrunken
- Bugscope Team http://bugscope.beckman.illinois.edu/members/2009-126/
- Bugscope Team there is a link on your member page that allows you to see the transcript with the images
- Bugscope Team you have to log in to see it not anonymized
- Teacher What is in the center of the screen?
Bugscope Team the head is in the middle. It has a giant compound eye staring at us
- Bugscope Team we had to start anonymizing it a few years ago when some guy tracked down his ex-wife using Bugscope
- Bugscope Team eye of the damselfly
- 8:14pm
- Bugscope Team lots and lots of ommatidia for some unfortunate grad student to count
- Bugscope Team there you go -- deus ex machina
- Bugscope Team the ommatidia shrink a bit when the eye dries out as well
- Teacher Why are there gaps between the lenses?
- Bugscope Team normally, in life, they would be swollen, as Cate says, no gaps
- Bugscope Team mosquito eyes are much like this as well
- Teacher Thanks
- Teacher This is Michele Korb again - we are signing off! Thank you! I will see you in the next two sessions!
- Bugscope Team Thank you for joining us for another bugscope session
- Bugscope Team Bye!
- Bugscope Team Thank You!
