• 8:01 am
• Bugscope Teamgood morning, or good afternoon in Germany!
• Bugscope Teamsample is being coated right now and will be in the 'scope in just a few minutes
• Bugscope Teamat this moment we see only the inside of the specimen chamber
• 8:07 am
• Bugscope TeamMrs Utter good morning!
• GuestGood Morning, Greetings from Deutschland.
• Bugscope TeamWelcome to Bugscope!
• Bugscope TeamI'll have a sample in in a moment -- we're venting the chamber now.
• Bugscope Teamthere were a few seconds there in which you could see me
• Bugscope Teamnow the sample is in the 'scope
• Bugscope Teamthe largest thing we see now, to the left, is a solitary bee -- a bumblebee
• Bugscope Teamwhat time is in the Deutschland?
• GuestSuper excited. It is now 3:10.
• Bugscope Teamah so we did not account for daylight savings time here
• Bugscope Teamon this end, we're waiting for the vacuum in the specimen chamber to get a bit better so we can start the electron beam, make a few quick adjustments, and start imaging
• 8:12 am
• Bugscope Teamin addition to the the large bee, which has a bunch of yellow stuff on its head, we have some tiny beetles, super tiny ants, some salt, pollen, flies, and a daddylonglegs
• Bugscope Teamalso a cranefly
• Bugscope Teamwhen the vacuum gets a little better I'll switch to the secondary electron detector, and the screen will go dark for a few seconds
• GuestSounds good. I had the students go to the computer lab to help with the set up there, and they will be back in a few minutes.... I hope.
• Bugscope Teamsuper cool
• Bugscope Teamvacuum is 1.7 x 10-3 mBar
• Bugscope Teamwe're going for 1.3
• Bugscope Teamsometimes it's like waiting for water to boil
• Bugscope Team1.6..
• 8:18 am
• Bugscope Team1.4
• Bugscope Teambeam on
• Bugscope Teamin a sec -- something outgassed...
• Guestno beam....
• Bugscope Teamfly head

• GuestWhy does the fly head have those big horns?
• 8:23 am

• GuestDoes the fly have any teeth?
• Bugscope Teamat the top of its head from our point of view are two antennae

• Bugscope Teaminsects do not have teeth. but sometimes the tips of their mandibles are hardened. this fly has sponging mouthparts so does not even have mandibles
• Guestwhat do they eat?
• Guestwhat do they eat
• Guestwhat is that
• Bugscope Teamflies can eat many things depending on the species

• Bugscope Teamsome eat rotting fruit (fruit flies)
• Guestwhat is that
• Bugscope Teamthey tend to like sweet things, but there are flies that like dung
• Guestdo they bite?
• Guestdo they eat vegies
• Bugscope Teamthose were tenent setae. they help the fly to walk on walls
• Guesthi
• Guestis tha t a eye

• Bugscope Teamno, but some flies can. There are flies that have piercing mouthparts
• Guestsup
• Bugscope Teami don't think flies care too much about veggies.

• Guesthey
• Guestwhat?
• 8:29 am

• Guestdo they have livs
• Guesthow do flys eat?

• Guestare you alive
• GuestIs that a tick on it?
• Guestyes
• Guestthe pearson talking
• Bugscope Teamflies have sponging mouthparts that will soak up the liquid. But first, since the food has to be liquid they will spit a little bit on to the food to dissolve it
• Guestcan bees bite?
• Guestdo flys have hair

• Bugscope Teamflies can live for a few days to a couple weeks
• Bugscope Teamyes, flies can have lots of hairs. The hairs help them to sense what is going on around them in their environment. Like sense of touch
• Guestdo they eat raw food
• GuestWhy are horseflys so big?

• GuestWhat is that hand looking thing
• Bugscope Teamhorseflies bite big animals and suck blood

• Bugscope Teamonly the females bite, like mosquitos
• Bugscope Teammale horseflies eat nectar
• 8:34 am

• GuestWhat is this?

• Bugscope Teamthose are hamuli. they hook the 2 pairs of wings together
• Guesthow do they suck the blood
• Bugscope Teamthey use cutting mouthparts like steak knives

• Guestwhat do they do

• 8:39 am
• Bugscope Teamthis is a daddy longlegs
• Bugscope Teamwith most of the legs broken

• Guestwhy are there so many different types of flies

• Guestwhat are the circles
• Guestwhat am I looking at?
• Bugscope Teamthe flies feed other animals. There are different species of animals that feed on different flies
• Bugscope Teamthese are pollen grains
• Guestwhat am I looking at?
• Guestwhat is this stuff
• Bugscope Teamthese are salt grains

• Guestwhat is this
• Guestcool
• Guestwhat is pollin grains?
• Guestwhat is this?
• Guesthow are these pollen grains
• Bugscope Teamthey fertilize plants

• Guestwhat is this
• Guestwhat is pollen grains
• Guestpollengrains
• Guestwhat are these?
• Guestwho are you?
• Bugscope Teamthis is what bees deliver to flowers so we can have crops
• Guestwhy is it bmpy
• Guestthat is weird
• Guestwhat is that?
• Guestwoo now i can see the fly
• Guestwhy is it bumpy

• 8:44 am
• Guestshow us more
• Bugscope Teamthe bumpy part is the compound eye
• Bugscope Teamit is also a bit lumpy because it dried up a little bit
• Guesteeeeewww
• Guestants?
• Guesteeeeeeeewwwwwwwww
• Guestwhat is that
• Guestgross
• Guestwhat's up?

• Guestthats so wierd!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Guesthelp!!!!!
• Guestis that a fly limb
• Guestwhat are these ?
• GuestIs that a centiped
• Bugscope Teamthis is a centipede

• Guestwhat is goss
• GuestCan we see an eye ball
• Guestcan I see an eye ball
• Guestcan i see the legs
• Guestplease can i see a eyeboll
• GuestCan I see an eye ball?
• Guestis this a fly?
• Guestcan I see a ant

• Guestwhat is that
• Guestcan I see an spider

• Bugscope Teamthe light parts on the side of the head are the compound eyes
• Bugscope TeamSky there is one spider, sort of -- it's the daddylonglegs
• 8:50 am

• Bugscope Teamwe don't find pollen on the bee, but on one of the flies

• Bugscope Teamthis is a small beetle
• Guestwha is this?

• Guestwhat is that?

• Guestdo you have an butterfly
• Bugscope Teamthis, now, is a beetle claw
• 8:55 am
• Bugscope TeamSky I am sorry -- we are in danger of striking out with you today. We do not have a butterfly, but you can see one of the scales of a butterfly or moth here in the claws
• Bugscope TeamNCS good morning!
• Bugscope TeamWelcome to Bugscope!

• Bugscope TeamNCS we have guests on from Germany today.

• Bugscope Teamyou have control of the microscope
• TeacherThanks! We're very excited!
• Bugscope Teamthis is the curve of the claw of the beetle, to the left, and to the right is a moth or butterfly scale
• Bugscope TeamNCS you may click on any of the presets to get the 'scope to drive to that area

• Bugscope TeamWe are sharing the microscope with our friends from Germany; they may be asking questions, but please be sure to ask us questions as well

• Bugscope Teamthe presets we made for today's session are on the lefthand screen.
• Bugscope Teamyou can click on a preset to get the microscope to drive to that stored position.
• 9:01 am
• Bugscope Teamand/or you may change mag, contrast/brightness, and focus right where you are

• Bugscope Teamthis bee is so big we cannot see all of its head at once
• Bugscope Teamone of the eyes is to the upper left
• Bugscope Teamwe're looking at its mandibles, and we see, in the middle, two small oval things, which are mites!

• Bugscope Teamnow we see the compound eye, with tiny facets on it called ommatidia
• Bugscope Teamto the left we see the antenna, which is segmented
• GuestWhy is it covered in hair?
• Bugscope Teamthe antenna has lots of chemoreceptors on it that allow the bee to 'smell' the air
• Bugscope TeamSky the hair we see helps keep the bee warm, or thermoregulate; it is also sensory, like a cat or rat's whiskers
• Bugscope Teamwith insects we call hair setae, or bristles, or spines, or microsetae, or trichae, or microtrichae, or, again, just hair
• TeacherDoes the hair catch the pollen?
• Bugscope Teamyes the hair catches pollen, but we have not seen much pollen on this bee so far; there is a lot of dirt, however
• Bugscope Teamthe pollen gets on the bee as it goes from flower to flower, and in that way pollen fertilizes other flowers, and that is what makes fruit form
• 9:06 am
• Bugscope Teamif we did not have bees doing the fertilizing for us, we would not have a lot of the crops we eat
• Bugscope Teamwould you like to see the mite on the other antenna/
• TeacherYes please!
• Bugscope Teamoops that was s'posed to be a question mark: antennae?
• Bugscope Teamnow you can see we've moved to the other side of the head
• TeacherSo are there bugs on bugs?
• Bugscope Teamthe mite is super tiny, and we can bring the magnification up to see it more clearly
• Bugscope Teamyes sometimes there are bugs on bugs on bugs
• Bugscope Teamvarroa mites are bad to bees
• Bugscope Teamcloser...
• Bugscope Teamthis is not a varroa mite -- they're much larger
• TeacherWhat do they do to the bees?
• TeacherIs a mite an arachnid?
• Bugscope Teamvarroa mites are bad for bees; they suck their 'blood' and make them weak
• Guesthow long do mites live
• Bugscope Teamsome mites are arachnids; I'm not sure if all of them are
• Bugscope Teamvarroa mites cause disease for honey bees
• Guestcan you show us the eye of the bee?
• 9:11 am
• Bugscope TeamMatt and Andy we are not sure about these; they do not have eyes, and we see them most often on earwigs. They seem to live on their hosts but we are not sure if they feed off of the hosts.

• Bugscope TeamDeniz we can go the bee's eye next.

• Bugscope Teamdust mites are much more crumpled looking because they are soft bodied. So we know it isn't a dust m3ite
• Bugscope Teamthis is a closeup of the surface of the bee's antenna
• Bugscope Teammite
• Bugscope Teamthe little plates are called placoid sensillae, and we think they are chemosensory; that is, they sense chemicals in the air, and by touch as well
• TeacherCan we see a stinger of a bee?
• Bugscope Teamyes we can!
• Bugscope Teamit is kind of scary
• 9:17 am

• Guesthow long do the bees live
• Guestwhat does the hair look like?
• Bugscope Teamwhen the stinger goes into your skin it slides, side by side, to cut its way in
• Bugscope Teamonly the honeybee stinger gets stuck in your skin
• Guestwhat does the hair look like?
• Bugscope Teamqueen bees may live for a few years; other bees live for shorter time periods, 40 days or more, usually
• GuestWhat is the thing just above the stinger?
• Bugscope Teamlet's go up close to see how the stinger works
• Bugscope TeamSky I am not sure what that is; I thought it might be a mite but couldn't figure it out
• Bugscope Teamhere we see the two side-by-side cutting portions of the stinger
• Bugscope Teamthey have barbs in them that help them cut and also stick into your skin
• 9:22 am
• Bugscope Teamvery sharp
• TeacherIs the stinger in 2 pieces or more?
• Bugscope Teamyes the stinger has two sliding portions
• Bugscope Teamstingers are modified ovipositors, so only females have them
• Bugscope Teamsometimes the stinger is also an ovipositor
• Bugscope Teamovum means egg; an ovipositor is an egg depositor
• Bugscope Teamthis is a pollen grain, I think; it's hard to tell
• Bugscope Teamit has a scale from a moth or butterfly on it
• Bugscope Teamof insects, only bees have these cool branched setae -- the hairs
• Guestcan you show the nose?
• 9:27 am
• Bugscope Teamlet's go up to see...
• Bugscope Teaminsects dont have noses, at least not like we do
• Bugscope Teamthey breath through holes that are along their bodies, and they smell with special hairs
• Bugscope Teamthese are the segments of the bee's abdomen
• Bugscope Teaminsects have a head, a thorax, an abdomen, six legs, and two antennae
• Guestwhere is the heart?
• TeacherWho are the predators of bees?
• Guestwhere are the mouth
• Guestcan you show me the centipede?
• Bugscope Teambirds will eat bees
• Bugscope Teamsome dragonflies will eat bees as well
• Guestwhat does do with it
• Bugscope Teamhoney badgers, honey birds, humans

• Bugscope Teamclaws are like hands to us. They help pick up and hold onto things
• Guestbutterfly
• Bugscope Teamclaws are used by insects very much the same way we use our hands, except insects generally do not type
• 9:32 am
• Bugscope Teamthis is the head of the bumblebee. if it had a nose it would be here, but insects do not have noses.

• Bugscope Teamnow we are looking at the edge of one of the bee's four wings
• Bugscope Teamants, bees, and wasps are related
• Bugscope Teambees and wasps, and ants when they have them, have four wings
• TeacherWhat is the stringy stuff?
• Bugscope Teamit's spider web!
• Bugscope Teamand a scale from a butterfly is stuck in it!
• Bugscope Teamscales, which are kind of like tiny feathers, fall out of wings and off of moths, mosquitoes, butterflies, and silverfishes' bodies quite easily
• Bugscope Teamif a butterfly flies into a spider web, it can sometimes wriggle out by leaving its scales
• 9:38 am
• GuestI just wanted to thank you for allowing us to join your class. The students and parents were amazed at the clarity of the images and the quick response to questions. Tschuss!
• Bugscope TeamMrs Krouse we have very much enjoyed having you on.
• GuestAuf Wiedersehen. Thanks again.
• Bugscope TeamThank You!
• Bugscope TeamAuf Wiedersehen!

• Bugscope TeamNCS this is a female fly's head.
• Bugscope Teamyou can see the compound eyes on either side.
• Bugscope Teamin the middle are the fly's sponging mouthparts and palps
• TeacherIs there a difference between a males head and a females head?
• Bugscope Teamwith flies, female's eyes are often far apart, like Uma Thurman
• Bugscope Teammale fly eyes are often close together, like Mikhail Baryshnikov.
• Teacherfunny!
• Bugscope Teamsometimes the males' eyes are almost touching
• 9:44 am
• Bugscope Teamfly antennae are small, usually
• Bugscope Teamthey have a kind of furry base and a branched portion
• Bugscope Teamfly's knee to the left, and compound eye to the right/middle
• Bugscope Teamthese are the individual facets of the eye, called ommatidia
• Bugscope Teamthey each get an image

• Bugscope Teamthey also see movement really fast so everything you do looks like it's in slow motion
• Bugscope Teamthis is the compound eye of an ant -- a super tiny ant
• Bugscope Teamit has perhaps 30 or so ommatidia
• Bugscope Team30-40 yeah
• 9:49 am
• Bugscope Teama large wasp can have 17,000 ommatidia per eye!
• Bugscope Teamand a dragonfly can have 30,000 ommatidia per eye
• Bugscope Teamspork
• Bugscope Teamto the left we see, since the ant's head is on its side, the bases of the two antennae
• Bugscope Teamto the right, the thing that looks like a spork is one of the mandibles
• Bugscope Teammandibles are jaws, and they open side to side like a gate
• Bugscope Teamcompared to humans, whose jaws open up and down -- the other way
• TeacherDo you have any dragonflies?
• Bugscope Teamno dragonflies today. sorry
• Bugscope Teamno dragonflies today, I'm sorry
• TeacherWhat are we looking at now?
• Bugscope Teamwe are looking at lily pollen, quite closely
• Bugscope Teamdragonflies have been around for thousands of years. They used to be really big in prehistoric times due to higher concentrations of oxygen
• 9:54 am
• Bugscope Teamit needs to be protected from drying out, and pollen also generally works better if it can stick to things
• Bugscope Teamyes we are lucky there is less oxygen in the air now or we would have to fight dragonflies to keep them out of the house
• Bugscope Teamwith like a bat or tennis racket
• Bugscope Teamhaha
• TeacherThank you both so very much for all of your time and expertise! We've learned so much from you both this morning!
• Bugscope Teamthis is a different kind of pollen that looks like baby rabbits
• Bugscope TeamThank You, NCS!
• Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2012-103
• Bugscope Teambelow is the link to your member page
• Bugscope TeamGood Bye, NCS!
• Bugscope TeamThank you for working with us today, and for welcoming our guests from Germany!
• 10:00 am
• TeacherThanks again. It was a wonderful experience!
