- 6:50 pm
- Bugscope Teamhello!
- Guestwhat is that
- Bugscope Teamwe are setting up now for shanghai
- Bugscope Teamwe were looking at a mosquito
- Guestcool
- Bugscope Teamthis is one of its claws
- Bugscope Teamthose little soccer-looking balls are brochosomes
- Bugscope Teamwhich are made by leafhoppers
- Guestsweet
- Guestwhat r leafhoppers
- Bugscope Teamjust a certain class of insects that live on plants, as you might imagine they like to hop
- Guestok
- Guesti got to go
- Bugscope Teamok thanks for hanging out with us!
- 6:57 pm
- 7:04 pm
- Guesthello
- Guestwhat ae we looking at now
- 7:10 pm
- Bugscope Teamright now we are looking at a decaying beetle that doesnt look very good
- Bugscope Teamhello by the way
- Guestthats so neat! My 7 year old is looking also
- Bugscope Teamthis is a tiny beetle, you can tell by looking at the scale bar in the lower right hand corner
- Guestshe says WOW
- Guestcan you see this beetle at all with the unaided eye?
Bugscope Teamyou can but it is very very tiny. I could barely pick it up
- Bugscope Teamwe were looking at a mosquito and a fruit fly earlier that looked pretty cool as well
- Bugscope Teamthis is a butterfly wing
- Bugscope Teamyou can see the individual scales now
- Bugscope Teamthe scales act like the feathers on a bird
- Guestshe is clapping her hands and says look at the ridges!!
- 7:15 pm
- Bugscope Teamthis is a bee we think
- Guestwhat is this
- Guestoic
- Bugscope Teamwhere are you located miller?
- GuestMaryland
- Bugscope Teamit has some juju all over it
- Guestlol
- Guestgreat technical term
- GuestSarah says it looks like a junk yard
- Guesthello
- Bugscope Teamthis is a pollen grain
- Bugscope Teamthe spiky ball is
- Bugscope Teamit looks like the compatibility test worked...we were on a wireless...for the real thing we will be contacted
- Bugscope Teamhello anthony
- Guestwhat is that
- Bugscope Teamthis is a pollen grain with crystals on it, which is currently sitting on what we think is a bee
- Guestgot to go
- Bugscope Teamthere was no stinger though
- Bugscope Teamok see you later anthony
- Guestwonder why...already got someone...
Bugscope Teammaybe
- Bugscope Teamyou can see it has "hairs" all over it. we call the hairs on insects setae (see-tee)
- TeacherHI!
- 7:21 pm
- TeacherRachel here, the kids aren't here yet though
- Bugscope TeamHello
- Bugscope Teamhey there rachel!
- Teacherhi!
- Bugscope TeamYay Hello!
- Bugscope TeamHey Scott
- Bugscope TeamHi Smiley!
- Bugscope TeamGrade 1 you should be able to click on a preset, if you would like, and the 'scope will move to that place.
- Teacherwe're just all getting set up in the room
- Teacherthat sounds great
- Bugscope TeamWe have a ladybug, a couple of true bugs, a moth, a mosquito, a fruit fly, and a few other critters on the stub today.
- 7:28 pm
- Bugscope TeamCate and I are here at Beckman, in the basement, with the electron microscope; Chas is at home; Annie is at yoga, for now; and I am not sure where Alex is.
- Bugscope TeamOh and Smiley is in Florida!
- TeacherNi Hao! that means hello in Chinese
- Bugscope TeamNi Hao!
- Bugscope TeamNi Hao =D
- GuestNi Hao
- TeacherOur first question, is what is a "stub"?
- Bugscope TeamThe stub is what the samples are all mounted on -- it is an aluminum disc.
- Teacherwhat are we looking at right now?
Bugscope Teamthese are setae (which are insect hairs) on what we think is a wasp
- Bugscope Teamall of the critters are stuck to the stub with doublestick carbon tape and silver paint
- Teacheris that hard to do?
Bugscope Teamit can be difficult not to smoosh them when picking them up. You will often see them with missing limbs, that could very well be my fault
- Bugscope Teamthis is the eye of a wasp -- part of it
- TeacherWOW!
- Bugscope Teamit is hard to do a good job, so Cate does it
- Bugscope TeamCate is very good at it.
- Bugscope TeamI agree
- Bugscope TeamShe also coats the insects with gold-palladium using a sputter coater. That makes them conductive.
- Bugscope TeamWould you like to try clicking on one of the other presets?
- Bugscope TeamHey Cool
- 7:33 pm
- Teacheris this a rolly poly?
- Bugscope TeamAre those all pollen grains?
- Bugscope TeamI am not sure what this is now.
- Teacherapparently a roly poly is a little black insect
Bugscope Teamwe don't have any roly poly's on here right now sorry. They are also called pillbugs that rollup into a little ball if you touch them
- Bugscope TeamThose are very small soccerball like things called brochosomes.
- Bugscope TeamAhhhhh...I should have remembered
- Bugscope Teamlet's take the magnification down so we can see where we are.
- Teacherwhat has pollen got to do with insects?
Bugscope TeamMany insects will pick them up when landing on flowers
- Bugscope Teamthere is the pollen grain (spiky ball)
- Bugscope TeamThey often encounter pollen, and sometimes, like bees, on purpose.
- Bugscope Teamthey are spiky which makes it easier for them to cling to the setae (see-tee)
- Teacherthat is really cool to know
- Bugscope Teamwe often see pollen, and sometimes we see mold spores, which look similar but are not as spikey.
- Bugscope TeamScott, are mold spores the same size as pollen grains
- Bugscope Teamthis is cool -- this is a closeup of the edge of a wing scale from a butterfly.
- TeacherWHOA!!!!
- 7:38 pm
- Teacherwhat is a wing scale?
Bugscope TeamThe scales are like tiny little feathers that coat the surface of the wing. To the eye they look like dust. They're loosely attached, so if the insect gets stuck to a spider's web it can shed a layer of scales and fly away
- Bugscope Teamthe scales are what make the wing feel soft when you touch it
- Bugscope Teamthey are kind of slick
- Bugscope Teamthey are much like feathers, on a bird
- Teacherthey are amazing
- Bugscope Teamone thing they do is help the butterfly or moth or mosquito escape from spider webs, because they come off easily.
- Bugscope Teamsilverfish have scales too!
- Bugscope Teamthis is the surface of an egg that a fruit fly was laying.
- Teachererr!!!
- Teacherwhat is the egg made of and does it have a yolk?
- Bugscope Teameverything ok?
- Bugscope Teamthe egg is probably made of a protein like chitin
- Bugscope TeamI think they are soft and kind of waxy
- Bugscope Teamit is very small
- Bugscope Teamcan you try clicking minus on the magnify control?
- Bugscope Teamsee if you can take the mag down
- Bugscope Teamif you wanted you could lower the mag and see how big it is compared to the fruit fly
- Bugscope Teamyay!
- Teacherwhy is it called a fruit fly?
Bugscope Teamthey like to eat rotting fruit, or at least an enzyme that is produced from rotting fruit
- Bugscope Teamyou find them around fruit -- they are kind of pests
- 7:43 pm
- Teachereeeeeeeeerrrrrrrrrrrrrrrrrrrrkkkkkkkkkkkkkkkkkk!!!!!
- Bugscope Teamthey seem to like the juices
- Bugscope Teamfruit juice is sweet
- Bugscope Teambut I thought they eat the mold on fruit also
- Bugscope TeamSmiley you are right
- Bugscope Teamthis is the mouth of the fruit fly
- Bugscope Teambizarre...wow...
- Bugscope Teamit is kind of spongy and built to be able to absorb liquids
- Bugscope Teamit acts like a sponge
- Teacherreally?
- Teacherthat is amazing
- Bugscope Teamthey often do not look so good
- Teacherwe have a question about the fruit fly eggs, do you know how many fruit flys are in each egg?
- Teacherwhat does critical point dried mean?
- Bugscope TeamI think there is just one of the little dudes, or dudettes, in each egg
- Bugscope TeamCate has the insects in ethanol, and she puts them into a chamber in which the ethanol is replaced with liquid carbon dioxide.
- Teacherwhy do you do that?
- 7:49 pm
- Bugscope Teamwhen the LCO2 is put under pressure and heated above the critical point it leaves the tissue in gaseous form and does not cause a phase change that would make the sample wrinkle up
- Teacherso that way we can see the insects clearer, cool
- Bugscope Teamyes we think that they release saliva from the holes and then suck it back up with the fungi/yeast that they want to eat.
- Teacherwe think it looks like an elephant!!!!
- Bugscope TeamIf you think about a worm drying on a sidewalk -- it does not look good when it dries in the sun
- Bugscope Teambut if we were to critical point dry the worm it would be round like it was originally
- Bugscope Teamnow you can see the eyes, which are domelike and have many facets to them called ommatidia
- Bugscope Teamand the things in the middle of the head that look furry are the antennae
- Bugscope Teamflying insects will almost always have bigger eyes than insects that live in the ground like beetles and ants.
- Bugscope Teamthey depend on their eyes a lot more
- Bugscope Teamyou can see that the insects have tiny hairs, which we call setae (seetee) all over them
- Teacherit looks like somebody made it from material
- Teacherwhat do they have such small attenae?
- 7:54 pm
- Bugscope Teamsome of the setae are mechanosensory -- they function like a cat's whiskers
- Bugscope Teamthe antennae have two parts -- the furry part and the branched part
- Bugscope Teamthey are indeed small and streamlined
- Bugscope Teamif they were much bigger the fruit fly might get blown around in the wind
- Bugscope Teamthe fruit fly eye, if you magnify to see it, has lots of tiny setae on it as well
- Teacherwe need to move onto some more slides but we can't get them to load, can you?
- Teacherwhats this?
- 7:59 pm
- Bugscope Teamthis is the mosquito proboscis
- Bugscope Teamthis is the part that pierces you
- Teacherooohhhhhhhhhh!!!
- Teacherit looks sharp
- Bugscope Teamit must be sharp to penetrate your skin
- Bugscope Teamit is very sharp and has little barbs to keep it in so it doesn't fall out too easily
- Bugscope Teamthe females mosquitos need blood so they can lay their eggs
- Bugscope Teamoh yeah...there are barbs...thats so neat
- Bugscope Teamthey need a blood meal
- Bugscope Teamthe males do not bite
- Teacherthat is cool
- Bugscope Teamthe lancet we see now is in a sheath that has scales on it
- Bugscope Teamyou can tell that the sheathe would not stick into your skin
- Teacheris the curvy part a hair?
- Bugscope Teamyes those are tiny hairs
- Teachercan we see one more slide, then we need to go
- Bugscope Teamwe are going to the lady bug
- Teacheryeah!
- 8:04 pm
- Bugscope Teamso as you can see the head is really streamlined
- Bugscope Teamthis is the face of the ladybug
- Teacherwe still can't see the head
- Bugscope Teamthe head looks burrowed into the body
- Teacherwe are still waiting for the ladybug stub to load
- Bugscope Teamum can you try refreshing the web page?
- Bugscope Teamit should be on there now
- Teacherwe got it!
- Bugscope Teamyay!
- Teacherwe think it looks like it has plastic around it
- Teacherwhat are the pointy things on the sides?
- Bugscope Teamit is like a little tank turret
- Bugscope Teamthe things that look like vacuum cleaner nozzles are called palps
- Bugscope Teamthe palps help it to eat and taste food
- Bugscope Teamthey have chemosensory setae in them
- Teacherthey do look like vacumn cleaner nozzles
- Teacherwhat do lady bugs eat?
Bugscope Teamlady bugs eat other bugs, but mostly they are good for eating aphids
- Bugscope Teamone of the antennae, which have club-shaped ends, is broken
- Bugscope Teamthey eat other bugs!
- Bugscope Teamthey are kind of mean
- Bugscope Team'cause aphids are soft and delectable
- 8:09 pm
- Teacherwe don't want aphids for our lunch
- Bugscope Teamno me neither
- Bugscope Teamof course not, i dont
- Teacherwe want to say thank you, xie xie!
- Teacherand good night
- Bugscope Teamit would take a lot of aphids to fill you up
- Bugscope Teamsome aphids excrete a sticky wax to keep from being eaten
- Bugscope Teamxie xie means thank you?
- Bugscope Teamgood night, and good day to you
- Bugscope TeamThank You!
- Bugscope Teamhow do you pronounce that?
- Bugscope TeamMy advisors wife is from China and her name is Xixi how funny
- Teacheryes shay shay (xie xie) is thank you
- Bugscope Teamcool!
- Teachergoodbye

- Bugscope TeamSmiley do you want to try driving? We have had a little trouble and are not sure it will work.
- Bugscope TeamCate is going to restart the server.
- Bugscope TeamSure...not sure whether my connection will be fast enough...
- Bugscope TeamDo I need to do anything while you restart the server?
- Bugscope TeamClaudi we are out of luck here.
- Bugscope TeamAwwwwwwwwwwww
- Bugscope TeamSo if I go to a preset it will not work?
- Bugscope TeamIt is not working for us and Colonel Chas and Alex are not available to help.
- Bugscope TeamCate says we are not cool enough to be able to fix it.
- Bugscope TeamCan I try =) ??? I am curious
- Bugscope Teambut you could try a preset for sure.
