• 7:28am
• Teacher hi!
• Bugscope Team Hi Juan!
• Bugscope Team We'll have the sample in the 'scope in just a few minutes and then make a few presets.
• Teacher Ok scot, i'm testing the netbooks before the session
• Bugscope Team I'm running back and forth between the lab and the microscope...
• Bugscope Team super cool
• Teacher don't worry! i'll wait

• Bugscope Team we don't know what will look good until we see it up close; that is, not everything will look good
• Bugscope Team the ants are so small that they cannot be placed easily, so they're often mashed or in odd configurations -- or they charge up with electrons and look tres terrible
• 7:39am
• Bugscope Team now we're waiting for the vacuum to get to the right level
• Teacher ok scott
• Bugscope Team sorry to be running a bit late
• Bugscope Team you should be able to check the netbooks
• Teacher don't worry scott
• Teacher i'm testing the nets rigth now

• Bugscope Team if you click on the screen
• Bugscope Team vacuum is at 1.7 x 10-4 mbar; we're going for 1.3
• Bugscope Team 1.6

• Bugscope Team once it gets down I'll turn the beam on, make a couple of small adjustments, and capture some presets
• 7:46am
• Bugscope Team 1.4
• Bugscope Team like waiting for water to boil
• Teacher scot, i will log off a few seconds

• Bugscope Team Hello Acta, and hello Juan

• Bugscope Team Colo and Melli we will have to look for one of the ants.
• 8:12am
• Bugscope Team In the meantime you have found a wild-looking beetle.
• Teacher scott, please give control to valen y guada
• Bugscope Team Valen and Guada are the supreme rulers
• Bugscope Team one of this beetle's antennae is missing

• Bugscope Team it has super spikey mandibles
• Bugscope Team its eyes are on the sides of its head, streamlined into the shape of the head

• Student can we look eyes plase

• Bugscope Team ask Valen and Guada to move to the edge of the head, if they can
• Student scot please can we see the eyes of the bee
• Bugscope Team by clicking on the image, whoever is driving can center the 'scope on that particular place

• Bugscope Team Fran and Melli your classmates are driving right now...
• Bugscope Team But Joe or I can help when someone needs help.
• Bugscope Team fancy setae at the mouth
• Bugscope Team now you can see the compound eye on the beetle's head
• Bugscope Team yeah it is an awesome looking beetle
• 8:17am
• Bugscope Team you can see the individual facets of the compound eye
• Teacher scot can you take a picture of this image ?

• Bugscope Team each of those hexagons are a unit called ommatidium, they each have a lens
• Bugscope Team you are collecting images as we work
• Bugscope Team these work together to create a complete picture for the insect
• Teacher thanks scott
• Teacher scot, please give control to mailen
• Bugscope Team this page http://bugscope.beckman.illinois.edu/members/2012-092 is updating constantly and has the chat and images on it
• Bugscope Team what they end up with is a mosaic of sorts, similar to a pixellated picture
• Bugscope Team Mailen is the supreme ruler now

• Student Can you focus on the wings of the bee
• Student How many degrees can the eye see

• Bugscope Team Mailen it depends but likely 240 degrees or so around the head
• 8:22am
• Student how many parts does the ant´s mouth have?
• Bugscope Team many flying insects also have simple eyes on the back of the head
• Bugscope Team some insects like the dragonfly can see nearly 360 degrees around
• Bugscope Team Aye and Jose it has two mandibles, four palps, a clypeus and a frons, but there are other parts I am not sure about
• Teacher scot, can you load the wasp ?
• Bugscope Team this beetle has a mouth in some ways similar to an ant

• Teacher scot, please give control to colo and melli
• Bugscope Team here we can see, on the right (a la derecha?) a dome that is one of the ocelli
• Bugscope Team you can see one of those simple eyes scot talked about
• Bugscope Team behind the compound eye
• Bugscope Team the weird bump there
• Bugscope Team you can see the antennae and also the palps
• Bugscope Team Joseph is an entomologist.
• Teacher scot, please give control to colo and melli
• Student there is a beetle? for near the sting
• Bugscope Team alright Colo and Melli you are the jefes of the 'scope

• Bugscope Team the large beetle has something that looks like a stinger, likely an ovipositor, Franco & Leo

• 8:28am

• Bugscope Team you can see now that there are loose scales from another insect on the compound eye and also the pedicel of the antenna
• Bugscope Team now you have one of the ocelli centered

• Bugscope Team you can see two ocelli now
• Bugscope Team if you want to see the wings they will be further south of here
• Bugscope Team the wrinkly crater in the background is a bubble in the doublestick tape
• Bugscope Team ants, bees, and wasps are related
• Teacher scot, please give control to ale y nathan
• Student thanks
• Bugscope Team suoer cool -- Ale and Nathan are now the supreme rulers
• Bugscope Team uh super cool..
• Student how many eyes are there in the composite eyes
• Student does the ant have hair on its thorax?
• Bugscope Team Ale and Nathan there are a few thousand; a large hornet can have as many as 17,000 per eye
• Bugscope Team that depends on the species, some will have very little, maybe seven or so, and others can have 10s of thousands

• Bugscope Team yes ants have hair (often called setae) on their thoraces

• Student scot please can we see the mouth of a mosquito?
• Bugscope Team insects have lots of setae because they use them to sense their environment
• Bugscope Team Fran y Melli ask Ale and Nathan to click on the mosquito...

• 8:33am

• Bugscope Team insects do not have skin like we do -- instead they have a shell, called an exoskeleton
• Bugscope Team this is the beetle

• Bugscope Team the insects have an exoskeleton, it's as if they're constanly wearing armor

• Student please how many parts does the mosquito mouth have ?

• Bugscope Team because insects do not have skin, they have tiny hairs called setae that stick through the shell and let them sense what is around them

• Bugscope Team they have the same number of parts as the other insects

• Bugscope Team Octa y Juan if we were able to see the fascicle, it usually has four sharp stylets, a siphon tube through which the blood flows, and another component that seems to wrap around the other parts
• Student can focus on a scourge of the mosquito
• Bugscope Team the fascicle is inside the tube we see now at the bottom of the screen
• Bugscope Team only here they have been modified, so that they are in a different form, allowing them to suck blood

• Bugscope Team above is the antenna, and we can tell it is a female antenna

• Student how many parts does the bee leg have?
• Teacher scot, please give control to franco y lea
• Bugscope Team they have control
• 8:39am

• Bugscope Team the bee will have a claw, I think five tarsi, a basitarsus, a tibia, a femur, a trochanter, and a coxa
• Student How can tell it is a female antennae?

• Student how cam telle it is a femela antennae

• Bugscope Team Mailen and Fran y Melli we can tell because it is not ornate like a male's antenna

• Bugscope Team male mosquitoes have frilly antennae, as do some moths

• Bugscope Team when we see the specimen glow like this it is because it is charging up with the electrons we are using to collect the images

• Bugscope Team these are the scales that rub off when you touch a butterfly or moths wings

• Bugscope Team we use a sputter coater to put a thin layer of gold-palladium alloy on the specimens, and sometimes that is not enough to make them fully conductive

• Student can focus on the mesothorax
• Student because the butterflay wuing has holes

• Bugscope Team some of these are coloured by pigments, the grooves and microstructures you see can also contribute to its colours
• Bugscope Team we also use silver paint to help ground the specimens
• Student please

• Bugscope Team scales can give color to the moth or butterfly. they also help the insect to escape from spider webs when the insect can shake the scales loose
• Student can we see the pedicel of the wasp?
• Bugscope Team Aye and Jose now have control!
• Teacher hi cate, thanks for your help
• 8:44am
• Bugscope Team it's the reason some insects are iridescent
• Bugscope Team Valen ask Aye and Jose to click on the wasp preset
• Student thanks for giving us was incredible control

• Student can we seethe polen sacks
• Bugscope Team sometimes male and female butterfly wings look very similar to us, but to the butterflies males and females look quite different because the scales produce colors in the ultraviolet wavelengths that we cannot see
• Bugscope Team Hey no problem, Thank you, Franco y Leo!
• Bugscope Team because we do not have a bee in the microscope we are not able to show you the pollen baskets
• Student how long can housefly head live?
• Teacher scot, please give control to alejo y santiagp
• Teacher santiago
• Bugscope Team I think they live, generally, about 6 weeks
• Bugscope Team Alejo and Santiago have control now.

• 8:49am

• Student how long a butterfly live?

• Bugscope Team that depends. Most live for a few months
• Bugscope Team there are some migrating monarchs that can live for around a year though
• Bugscope Team hmm, yea about a month or two usually
• Bugscope Team this is the fly's mouth
• Teacher scot, please give control to agus y tomi
• Bugscope Team it has sponging mouthparts

• Bugscope Team Agus y Tomi have control now.

• Bugscope Team this is a pair of claws on a large beetle
• Bugscope Team one of the claws looks like it is bent outward

• Bugscope Team super cool Franco y Leo

• Student Thanks scot.
• Teacher scot, please give control to octa y juan
• Bugscope Team Octa y Juan are now the bosses.
• Student can show the palps
• 8:54am
• Bugscope Team ask Octa and Juan to click on the beetle head...
• Student why do the wings of insects have lines?
• Bugscope Team from the presets...
• Bugscope Team the wings have tiny setae on them called microsetae, usually, and they also have veins in them that follow a kind of branching pattern

• Student how many legs does the beetle

• Student how many eyes are in the compound eye of the bee
• Bugscope Team they have 6 legs
• Student how long ar the legs of a beethe

• Bugscope Team the beetle has 6 legs, as do all insects
• Bugscope Team the veins can be pumped up with hemolymph, for example as the insect is metamophosing into an adult

• Bugscope Team the length of the legs depend on the species

• Student how clong are legs of a beetle

• Bugscope Team some like the harlequin beetle will have extremely long forelegs
• Bugscope Team Colo y Melli it just depends on the beetle

• Student where the beetle eats

• Bugscope Team that also depends

• Student few parts have the legs of the wasp?

• Student that depends
• Student how many eyes are in the compound eye of the bee
• Bugscope Team others like a dung beetle are detritovores

• 8:59am
• Bugscope Team wasp legs have tarsi, a tibia, a femur, a trochanter, and a coxa; I am not sure if they have a basitarsus as well
• Bugscope Team the feed on decaying organic matter
• Bugscope Team these ommatidia are shrunken
• Bugscope Team it makes them look like little stars

• Student ok ok
• Student scot please because the wasp elojo hexagonal shaped ?
• Bugscope Team hexagon is the best shape to fit as many of the facets as possible in the curvature of the eye.
• Bugscope Team Octa y Juan the facets of the eye, called ommatidia, are often hexagonal because that happens to be the best shape for stacking what are essentially round objects into a dome shape. Um as Cate said...
• Student Breathe where ormigas
• Student thanks for answering my question scot
• Student SCOT, we are in an interview with a channel here! :)
• Student scot, which is focused on the microscope, it is?
• Bugscope Team Ormigas breathe through spiracles, like other insects.
• 9:04am
• Bugscope Team Agus y Tomi this is the cranefly's eye, up close.
• Bugscope Team now you can see where we are!
• Student hexagon is the best shape to fit as many of the facets as possible in the curvature of the eye.
• Bugscope Team this is the head of the crane fly, which looks like a giant mosquito

• Bugscope Team yup like a soccer ball
• Bugscope Team Octa y Juan that is correct -- thank you!

• Bugscope Team except without the pentagons

• Bugscope Team *football
