- Bugscope Team sample is pumping down
- Bugscope Team we are ready to roll!
- Bugscope Team Welcome, Mustangs!
- Bugscope Team good morning, Mustangs!
- Bugscope Team welcome to Bugscope!
- Bugscope Team you have control of the microscope
- Bugscope Team please let us know if you have any trouble, or of course if you have questions
- Bugscope Team we like questions
- Bugscope Team you can see the presets, on the lefthand screen, and if you click on one, the microscope will drive to that place on the stub
- Bugscope Team can you see this?
- Teacher Good morning! We are waiting for the other class to join us, then we will be all set. :)
- Teacher We can see the images.
- Bugscope Team Exxxxxxcellent.
- Bugscope Team super cool
- Bugscope Team this is the antenna of the leafhopper, and to the lower left we can see its hexagonal ommatidia
- Bugscope Team ommatidia are the facets of a compound eye
- Bugscope Team Scot is moving over a bit.
- Bugscope Team this is a s
- Bugscope Team Looks like 400um.
- Bugscope Team small one, about 400 microns, or 0.4 mm.
- Bugscope Team SLOW. SCOT IS SLOW.
Bugscope Team haha
Bugscope Team :)
- Bugscope Team If you want to see where you are at, you can zoom out by clicking the red "-" button next to the word Magnification. (If you don't see the "+/-" buttons, please let us know.)
- Bugscope Team Also, to move around, you simply click on a point in the image. Whatever you click upon will be the center of the new images.
- Teacher What is the part that looks like a hole in the bottom right?
Bugscope Team it's an indented part of the head that the base of the antenna (the pedicel) fits into
- Bugscope Team leafhoppers are interesting because they spread nanoparticles called brochosomes all over their exoskeletons and also on their eggs
- Bugscope Team we can see the brochosomes if we go to a higher magnification
- Teacher okay - the magnification +/- are not showing up on our end but did on the test and last year
Bugscope Team Can you tell me what OS and browser you are currently using?
- Teacher Do the brochosomes make the exoskeletons have a rough texture?
Bugscope Team it looks rough on the image here, but the brochosomes make the texture more waxy than rough, if you were to feel them
- Teacher windows 7 and chrome
Bugscope Team We saw this problem for the first time on Tuesday. Chrome must have changed something in a recent update. :( I'll try very hard to not rant about Google right now...
- Bugscope Team here are some brochosomes
- Bugscope Team are you able to use another browser?
- Teacher Do the leafhoppers look like a leaf ? Is there a way to zoom out far enough to see the whole insect too?
- Teacher We are also wondering where you can find a leafhopper or if we might know it by a different name.
Bugscope Team they are the little dudes and dudettes you see when you brush your arm across a bush, outdoors; they hop!
Bugscope Team they are often quite small
Bugscope Team I've seen quite a few of them this year. Most I've seen range from 0.5-0.7cm (about a quarter inch). They are often bright green and have a wierd wedge shape. They jump when you poke them and are entirely harmless to people.
- Bugscope Team they are usually 250 to 400 nanometers in diameter, meaning that some of them are thinner than the wavelengths of visible light.
- Bugscope Team a brochosome is 250 to 400 billionths of a meter in diameter, or 250 to 400 millionths of a millimeter!
- Bugscope Team we just gavre
- Teacher let me switch browsers
Bugscope Team Firefox (latest) works.
Bugscope Team We'll pass control to Mustangs2
Bugscope Team Mustangs2 should work right now.
- Bugscope Team Are the buttons there now?
- Bugscope Team we just gave you control as mustangs2
- Bugscope Team (Please say yes! please please please please please.)
- Bugscope Team can you see the brochosomes now?
- Teacher yes
- Bugscope Team yay!
- Bugscope Team be sure to select from the other presets
- Teacher sorry, no firefox and internet explorer was not connecting either
Bugscope Team brave new world. we're working on the next version of our software
- Bugscope Team we are happy to change mag, etc. for you
- Bugscope Team I'm sitting at the microscope.
- Teacher thanks!
- Bugscope Team fruit fly!
- Teacher Cool!
- Bugscope Team you can see its compound eyes and the cover to its sponging mouthparts
- Bugscope Team on either side of the mouth are the palps, which are kind of furry-looking
- Teacher now we are looking at the eye?
- Teacher We have to stay with Chrome, sorry
Bugscope Team Ok. We'll handle mag changes for you then. Just tell us when you want to zoom in or out.
Bugscope Team Sorry for the trouble. Chrome issues silent updates all the time, far more frequently than Firefox. When they break something, we usually don't find out about it until during a session. :(
- Bugscope Team here are some of the eye facets, called ommatidia, on the fruit fly's head
- Bugscope Team we can see that it has been hanging around with leafhoppers
- Teacher wow!
- Bugscope Team this is a wasp!
Bugscope Team the wasp has forked mandibles
- Bugscope Team insect mandibles (jaws) open sideways, like a gate
- Teacher so the jaw opens sideways?
Bugscope Team yes
- Bugscope Team the antennae are covered with chemorececptors that help the wasp smell and taste its environment
- Bugscope Team some of the receptors are touch receptors, for chemicals, and some are for chemicals that are in the air
- Teacher do wasps ever "sting" with their jaw or is it just for eating?
Bugscope Team no they sting with their abdomen - also only females sting
- Teacher wow, that is cool!
- Bugscope Team they could bite with their jaws to hold on and sting better maybe
- Teacher is that the same with bees?
Bugscope Team yes it is!
Bugscope Team and ants as well
- Bugscope Team some ants have stingers as well, and some have little volcano-like openings at the tips of their abdomens that release formic acid
- Teacher do male wasps and females wasps look different besides the stinger?
Bugscope Team yes, males tend to have bigger eyes
- Bugscope Team T.J. is an entomologist; she studies insects and comparable arthropods, like ticks.
- Teacher very cool
- Bugscope Team do you recognize this?
- Bugscope Team its antennae are broken off, so sad
- Bugscope Team it has a little hood
- Bugscope Team (it's a roach!)
- Teacher a roach?
- Teacher or a beetle?
- Bugscope Team they are very streamlined; they can live anywhere
- Bugscope Team And eat just about anything.
- Bugscope Team they do not have specialized features like many other insects
- Teacher we would like to see the bee stinger
Bugscope Team yay!
- Bugscope Team we can see that the stinger has sharp parts that slide, side by side
- Teacher what is the part that looks like a web?
Bugscope Team the tip of the abdomen is kind of dirty, and besides hairs, called setae, that are there, we can see some fungus
- Teacher class says "ew" to the fungus!
Bugscope Team Hahaha!
- Bugscope Team Fun fact: the reason only females have stingers is because it's a modified ovipositor - or device that aids in laying eggs. Some wasps use their stinger so that they can lay their eggs inside other insects like caterpillars
Bugscope Team And a gross fact: when those eggs hatch, the wasp larva eat the caterpillar from the inside out! When they're ready, they burst through the side of the poor caterpillar, make little cocoons, and pupate.
- Teacher what are we looking at now?
Bugscope Team this is a fly
Bugscope Team a big fly
- Teacher how does the stinger work?
Bugscope Team it sticks into the skin, and it slides side by side to better pierce the skin. stingers are the same thing as an ovipositor, which in the queen bees is used to lay eggs. some wasps use their ovipositor/stingers to both paralyze their prey and lay eggs in it. now that I'm finally done typing all of this I see that TJ beat me to it...
Bugscope Team whoops sorry Scot
Bugscope Team no problem at all, TJ!
Bugscope Team Hahahaha. He was just crying. "Oh, all my wasted typing! boo hoo hoo!"
- Bugscope Team robber fly
- Teacher what types of things do flies eat?
Bugscope Team They eat other insects
Bugscope Team They're really sneaky flies...sometimes they grab their prey right off of a leaf or flower mid flight!
- Bugscope Team this is cool
- Bugscope Team this is a spiracle-like opening at the tip of the palp
- Bugscope Team totally gnarly
- Teacher what is the black part here?
Bugscope Team It is a chemoreceptor. It senses chemicals.
Bugscope Team You can think of it like a tastebud for the fly.
Bugscope Team Or a nose :)
- Teacher could we move to the moth wing?
- Teacher I mean, moth scale on the wing
Bugscope Team Here you go!
- Bugscope Team so pretty!
- Teacher thanks!
- Bugscope Team the lines we see are so thin that they interfere with light and create what are called structural colors
- Teacher do robber flies bite humans too?
Bugscope Team Nope, they aren't hematophagous (blood feeding) so they don't really have any reason to
Bugscope Team They they can bite people if you grab one and really bother it
- Teacher thanks!
- Teacher can we zoom out and then zoom back in?
Bugscope Team There's what the scale looks like.
Bugscope Team It is on the abdomen of the wasp. It was transferred there, probably by us.
Bugscope Team It is very small. Ranging about 50-100um long (about the size of a human hair).
- Teacher wow!
- Teacher wow!
- Teacher Thank you so much!
- Bugscope Team structural cololrs are different from colors produced by pigment; some of the structural colors we cannot see because we cannot see ultraviolet light
Bugscope Team Fun Fact: If we were bees we could see these colors because bees can see UV light
Bugscope Team bees are lucky that way!
- Bugscope Team http://bugscope.beckman.illinois.edu/members/2014-062
- Teacher we are out of time here
Bugscope Team Oh no! So soon! We hope you participate again. Hopefully we'll get that annoying chrome bug fixed!
- Bugscope Team Thanks for joining us :)
- Bugscope Team below is a link to your member page, but it needs to be modified so it has a colon in it when it shows up on a web page
- Bugscope Team That URL that Scot posted works if you copy and paste it. Unfortunately, we found another bug in that the hyperlink is missing the colon. That should be an easy fix.
- Bugscope Team Thank you, Everyone!
