• Bugscope Teamwe are pumping down
• 12:25 pm

• Bugscope TeamCaddisfly larva shell

• 12:31 pm

• Bugscope Teamhi
• Bugscope Teamwelcome to bugscope

• 12:37 pm

• 12:44 pm

• 12:49 pm

• 12:55 pm

• 1:05 pm

• Bugscope TeamSession is unlocked.
• Bugscope Teamwe are ready
• 1:10 pm

• 1:33 pm
• Bugscope Teamcool diatoms, even if they are covered in CPD stuff
• Bugscope TeamHi Cate!
• Bugscope Teamhi sly
• Bugscope Team?
• 2:21 pm
• Bugscope TeamHi cheryl!
• Bugscope Teamwelcome to bugscope!
• Bugscope TeamHi Cheryl!
• Bugscope Teamwe are ready for you anytime
• Bugscope TeamThis is Scott, but we are listening to Dub music in the lab so I signed on as Sly Dunbar. Alex is, like, Robbie Shakespeare.
• Bugscope Teamlet us know if you have any questions
• Bugscope Teamyeah Cheryl you should try driving!
• 2:29 pm
• TeacherHi, this is Cheryl. I am still getting set up so running around for another few minutes.
• Bugscope Teamok, no problem, we are here and ready anytime you are
• 2:41 pm
• TeacherI'm here. the kids will be here soon. What am I looking at on the neck area?
• Bugscope Teamthose are some kind of organisms that live in the water, like vorticella. we don't know just what they are
• TeacherSo are they a kind of parasite of symbiotic thing?

• Bugscope Teamwell we think they are likely symbionts

• Bugscope Teamthey are much larger than vorticella. we have seen them before but are not sure what they are
• 2:46 pm
• Bugscope Teamwelcome to bugscope tut422, muffin, grace, marie, etc
• Bugscope TeamVorticella have stems like that, and cups sort of like that, and they eat bacteria and stuff in the water. it is cool that we have seen boatloads of bacteria on some of the samples today
• Bugscope Teambe sure to ask us questions about the samples or the microscope, or other things
• Bugscope Teamthis is a stonefly larva head
• Bugscope Teamthese aquatic insects have similar features to land based insects, but there are differences
• Bugscope Teamthese are the water-living forms of three flies, and we don't know much about them but will do our best to answer questions
• Bugscope Teamthese are considered nymphs
• TeacherThe kids are arriving. I'm going to do intros and instructions and then we'll be ready to roll
• Bugscope Teamand they are sort of like aquatic caterpillars
• Bugscope Teamok
• Bugscope Teamok sounds great
• 2:53 pm

• Bugscope Teamsee the mouthparts?

• Bugscope Teamthese are two sets of palps that help the stonefly larva taste its food, and push it toward its mouth.

• Studentwhat bug is this
• Studentwhat is the hair stuff
• Bugscope Teamcompared to a terrestrial insect, we see many more tiny setae that help it filter the water
• Studentwhat do they eat
• Bugscope Teamthis is a stonefly larva
• Studentwhat are the very fine hair stuff?
  Bugscope Teamthose are called setae, they help the insect to feel it's way around
• Bugscope Teamthe setae (hairs) are much longer and stringier here than they are on land based insects... that's because these are aquatic insects

• Studentare those thorns
  Bugscope Teamwell, there are some large antenna, and then the smaller hair like things are called setae (pronounced see-tee)

• Studentwhats the big tube yhing
  Bugscope Teamthat's an antenna
• Bugscope Teamthese mostly eat dead plants and algae

• Bugscope Teambut some of them are carnivorous

• Bugscope Teamthe hairs (setae) help the insect to sense its environment

• Bugscope Teamthese aquatic insects have a shell, like a shrimp, for example, that is made of chitin

• Bugscope Teamthe shell, as Alex said, is called an exoskeleton

• Bugscope Teamtheir exoskeleton is like a suit of armor
• Bugscope Teamthe setae stick through the exoskeleton to nerves underneath, that's how they feel things
• Studentdoes it have an exoskeleton
  Bugscope Teamyes it does!

• Teacherwhat is this?
• Studentwhere does it live
  Bugscope Teamall these insects are aquatic, so they live in water, streams, lakes, etc.
• 2:58 pm
• Studentwhat is that

• Bugscope Teamso because it has an exoskeleton, it is similar to if you were wearing armor, as Alex said

• Bugscope Teamthose little flar bumps are some kind of sensilla -- a sensory organ that may pick up chemical smells in the water, for example

• Studentwhat color is it
  Bugscope Teamhard to say, especially after we put them through a drying process called critical point drying where usually the color of the insect will go away leaving the insect white. We are beaming electrons at the sample instead of photons, so we dont get any color signal back. That's why the images are colorless

• TeacherWhat is this?
  Bugscope Teamthis looks like some kind of water mite, but we don't know for sure
  Bugscope Teamwe aren't sure what kind of organism this is, but it's on a stonefly larva

• Studentwhat are all those fuzzy things?
• Studentis that its back or its leg?
• Studentis it dangeruos
  Bugscope Teamwe don't think they are dangerous, not to people
• Studentwat cind of insect
  Bugscope Teamit is a stonefly larva
• Bugscope Teamthe stonefly larvae are brown to yellow

• Bugscope Teamstonefly's are larva for almost a year, then they are an adult for only a day, they reproduce, and then they die
• Studentwhat are those

• Studentare those claws used to eat with or maim other insects?
  Bugscope Teamthey are probably used more for attachment, since most stonefly larvae are herbivorous

• Bugscope Teamthose are some of the claws
• Studenthow big are there claws
  Bugscope Teamvery small, we are magnifying 90x. but look at the scale bar in the lower left, that tells you, it's about 200 microns across.

• Studentnice
• Studentwhat does it eat
  Bugscope Teamthey eat mostly algae and decaying plant material

• 3:03 pm

• Bugscope Teamthis is another stonefly

• Bugscope Teamone um = one micron = one millionth of a meter
• Studentwhere are it's eyes?
  Bugscope Teamthey are on the sides of the head

• Bugscope Teamyou can see one of the eyes now
• Studentis it the same animal
  Bugscope Teamthis is another of the same nymph of the stonefly

• Studentcool

• Studentwhat dose it eat
  Bugscope Teamthey eat algae and plant mater
• Studentwhat is that thing

• Bugscope Teamthat is the eye!
• Studentwhat are the tube things used for?
  Bugscope Teamthose are antennae, so they pick up chemical signals int he water, and vibration -- they are sensory organs

• Studentwhat are those circles in the background?
  Bugscope Teamwell, here we are looking at a compound eye, those circles are the eye facets, called ommatidia

• Studentcool
• Studentwhat is this bug?
• Studentso, they have claws, but do they use them to climb or eat ,like humans?
  Bugscope Teamyes they can use them like we use our hands- to grab onto things. Sometimes we will see little pads of setae near them that are used to help them walk on vertical surfaces
• Studentwhat does it eat
  Bugscope Teamalgae and decaying plants

• Bugscope Teameach bump on that eye is a facet, called an ommatidia, each one has a lens in it
• StudentIt is like a fly's eye!
  Bugscope Teamtotally, many insects have those compound eyes like flies do

• Bugscope Teamsome stoneflies eat other insects

• Studentwhat are those spiky things?
  Bugscope Teamthose are setae (pronounced see-tee), they help it to feel its way around

• Bugscope Teamthis is a mayfly larva now
• Bugscope Teamwe had landed on the jaws
• Studentwhat does it eat
  Bugscope Teamplants and decaying material
• Studentwhat do they use the 3 tails for?

• 3:08 pm
• Studentare those the ribs?

• Studentwhat are those flat things on the head
• Studentwhere are the gills?

• Studentis that shade used for protection, or as some kind of filter?

• Studentwhat is it?
• Studentwhat are the stone things
• TeacherAre these the gills?

• Studentdum de dum
  Bugscope Teamheh
• Studentare those legs
  Bugscope Teamyeah, we think those are prolegs

• Studentis that it's lungs?

• Bugscope Teamthe gills are on the dorsal side, so we think these are prolegs of some kind

• Studentare these rocks
  Bugscope Teamno rocks here i'm pretty sure

• Studentwhat are those tube things?
  Bugscope Teamthose are cerci

• StudentIs that shade used for protection, or as some kind of water filter?
• Studentdoes the tails grow back like a starfish?

• Studentwhy does it have 3 tails
  Bugscope Teamprobably helps it to maneuver in the water

• Studentis that algae on it's tail or whatever?
  Bugscope Teamwe think so, yes, there is a lot of algae and diatoms on these critters..
• Bugscope Teamcerci are the spine that come off of the abdomen, like on a roach, and often they are sensory -- they may initiate an automatic fleeing response to stimulus

• Bugscope Teamthe cerci have little anchors on them that may help them attach to the substrate

• StudentThanks!
• Studentso is this supposed to be like email

• Studenth]
• Studentwhat do they eat
  Bugscope Teamthey eat plant matter mostly
• Studenthi
  Bugscope TeamHi Megan!
• 3:13 pm
• Studentwhat are those three tube things
  Bugscope Teamthose are cerci
• Studentis this broken
  Bugscope Teamyes, sorry
  Bugscope Teamyeah looks like it broke. Limbs can break easily once the insect is dead because they are dried out
• Bugscope Teamsome mayfly nymphs are detritovores, and some scrape food of of surfaces, mostly algae and organic material in the water

• Bugscope Teamthis is the head of a large mayfly nymph

• Studentcan the tails grow back like a starfish leg?
  Bugscope Teamhmm, i don't know cleave, but probably not as well as a starfish can. some insects can regrow parts when they molt though

• Bugscope Teamyou can see the compound eye, and you can see one of the antennae
• Studentwhat does detritovores mean
  Bugscope Teamit means they eat detritus, which is decaying material in the water

• Studentis it sensitive
  Bugscope Teamit is sensitive enough to survive, yes
• Studentwhat is a compound eye?
  Bugscope Teama compound eye has many different facets, each of which collects an image that is sent to the brain for processing

• Studentthe antenne, or whatever it is look like turnips
  Bugscope Teamyeah they do!
• Bugscope Teamthe facets of the eye are called ommatidia
• Studentis this the head?
  Bugscope Teamyes it is!
• Studentis a compound eye like lots of eyes put together?
  Bugscope Teamyes it is, and it gives the insect good peripheral visiion
• Bugscope Teamand Marie those are antennae
• Bugscope Teamyeah, compound eyes are really cool. it's like seeing a thousand different images at once
• Studentwhat is the fuzzy stuff between the eyes
  Bugscope Teamwell, some of it might be diatoms or decaying plant matter
• Studentthat eye is big under magnification, but how big is it on a human scale?
  Bugscope Teamlook at the scale bar in the lower left, that'll tell you true size
• Studentwhere do they live
  Bugscope Teamthey live in streams, on rocks
• StudentThanks for doing this Cheryl!!!
• TeacherMy pleasure!

• Studentare those it's feet?
  Bugscope Teamthose are tiny setae

• Studentwhat are those pointy things on the stonefly larve?
  Bugscope Teamsorry not sure which pointy things

• 3:19 pm

• Bugscope Teamthose are sensory setae, we think

• Studentcreepy
• Studentthis is fun scot
  Bugscope Teamyes it is for us too!
• Bugscope Teamwhat we see now are palps
• Studentwhat is this
  Bugscope Teamthis is a stonefly nymph head
• Studentis that his mouth
  Bugscope Teamyes this is the mouth of a stonefly nymph
• Studenton its mouth
  Bugscope Teamthere is a lot of detritus -- stuff that filtered out of the water
• Studentweeee do de weeeee
• Studentwhat are the pointy parts on the outside of the mouth? with fuzzy tips?
  Bugscope Teamthose were palps, which help insects taste and manipulate food toward their mouths

• Studentwood
  Bugscope TeamValine one of the caddisfly larvae seems to have used wood to make its case.

• Studentare you holding these animals captive in illinois, or have you already took these pictures?
  Bugscope Teamheh, these insects are inside an electron microscope as we speak, and cheryl is controlling that scope live over the internet
• Studentit looks like a mummy
  Bugscope Teamyeah and it kind of acts like a mean living mummy too
• Studentthe body looks like a mummy is that because its larvae?
  Bugscope Teamhaha yeah larvae often look like that
• Teachercan we try to switch controls to "muffin"?
• Bugscope Teammuffin has control now
• Bugscope Teamthis one is out of its casing
• Studentcache/current_image.php?expireCacheWith=12

• Student muffin your in charge

• Bugscope Teamsome of the long things we see are plant fibers
• 3:24 pm
• Bugscope Teamall insects have those hairs (setae), they are needed because the exoskeleton is very hard and can't feel anything
• Studentplant fibers?
  Bugscope Teamthe loose long things looked like plant fibers; it depends on where we were looking
• Bugscope Teambut those setae stick through the exoskeleton to nerves underneath

• Studentare thosse little bugs?
  Bugscope Teamthose little pill-shaped dudes are bacteria -- some kind of bacillus
• Studentis that the longest waundering antenne?
  Bugscope Teamnot sure sorry

• Bugscope Teamnice muffin, going for the high mag huh?

• Bugscope Teambactieria!
• Bugscope Teamoops can't spell bacteria
• Bugscope Teamthe scope can magnify up to 600,000x, but for these insects, 40,000x is usually the most you'll see anything well

• Studentwow, nice job Muffin!

• Studentwhat are we looking at?!
• Bugscope Teamtutu0422 has control!!!
• Bugscope Teamthis is a closeup of the stonefly nymph antenna

• Studenttutu your in charge
• Bugscope Teamit looks like a pagoda

• StudentAnd you are Aleshiah, Aleshiah :)
• Studenthttp://bugscope.beckman.illinois.edu/axis_cache/current_image.php?expireCacheWith=1268515940038
  Bugscope Teamis everything okay valine?
• Bugscope Teamthey are similar to antennae in terrestrial insects but up close they are different -- adapted for a water environment
• Studentin the bleu Ferndale sweatshirt:)
• Studentwhats that
• Bugscope TeamValine hit refresh on your browser.
• Studentwhat are the strip like thingies
  Bugscope Teamthose are various likely chemosensory setae
• Studentsee the holes? can we get some info?
  Bugscope Teami think those are holes where setae used to come out but broke off
• 3:29 pm
• Studentyes
• Bugscope Teamland based insects would have holes like that, which would be for breathing, they are called spiracles
• Studenthmm.........
• Studentwhat are we looking at
• Bugscope Teamsee above the hole is another setae that is inside a similar hole
• Studentsomebody new should be on the controls soon.
• Studentyum yum yum yum um
• Bugscope Teamgrace has control now
• Bugscope TeamGrace is now the supreme ruler.
• Bugscope TeamGrace you can choose from among the presets, take the mag up or down
• Bugscope Teamdrive off the edge of the stub...
• Studentsly are you on the computer
  Bugscope TeamI am also Sly when I am on the microscope.
• Bugscope Teamlet us know if you would like to see the inside of the microscope, briefly
• Studentare you entemologists?
• TeacherCan we switch controls to Jebediah in about 2 minutes?

• Studentvery funny, scot!
  Bugscope Teamgracias
• Studentg
• StudentThe Brain?!!!!!!!!!!!!
  Bugscope Teamthis is one of the palps
• Bugscope Teamjeb, you've got control now

• Bugscope Teampalps help it to taste food, or manipulate food into its mouth
• Bugscope Teampalps often have features like tastebuds on them

• Studentcan antennae grow back?
  Bugscope Teamthey could if the insect molted; I am not sure these guys molt
• Studentcheryl can i be on the contrels
• Studentwhat is it?
• Studenti sugest the thorax.
  Bugscope Teamokay!

• 3:34 pm

• StudentAlex are you an entemologist
  Bugscope Teamno, i'm a systems adminstrator, scott and cate are electron microscopist

• Studentwhat insect is this?
• Bugscope TeamCate and I are electron microscopists.

• Studentwhat is this

• StudentYou are quiet over there Muffin :)

• Bugscope Teamroaches have these
• Bugscope Teamtoo

• Bugscope Teamthey're like long tails, and often they are sensory

• Studentthat's a lot of legs. those are legs ,right?
  Bugscope Teamthose are not technically legs

• Bugscope Teamthese have tiny setae on them

• StudentInteresting?
  Bugscope Teamthese it is hard to tell whether they are chemosensory or mechanosensory

• Studentis it dangerou
  Bugscope Teamthey're not dangerous to us
• Studenthow many legs do stoneflys have?
  Bugscope Teamsix
• Bugscope Teamthey may help detect water currents
• TeacherCan we switch controls to to valise?
  Bugscope TeamValine? Valise would be, like, a suitcase?
• Bugscope Teamvaline, right? valine has control
• 3:39 pm

• Studenti am going to watch for awile

• StudentCheryl, boxes keep coming up?
  Bugscope Teamwhat are the boxes?

• Studentwho is tutu0422
• Bugscope Teamtry clicking on a preset, like no 23
• Guestwerid
  Bugscope TeamVeronica!
• Studentwhat are they dangerous to
• Bugscope TeamValine you are at high mag. You can take it down if you want, or go to a preset.
• Studentwow
• Guestwhat is it
  Bugscope Teamthis is a caddisfly larva
• Bugscope Teamyou are at 200,000x and there is not much to see there.
• Bugscope Teamgoing this high mag won't work too well, we'd have to change the working distance.
• StudentHow is the weather over in Illinois?
  Bugscope Teamcloudy, mid 40's, but it's a nice relief from the 0's we had a couple of weeks ago

• Studenti am in control now
  Bugscope TeamYay!

• Bugscope Teamthese guys often build shells for themselves

• Studenthow many inst do you have
  Bugscope Teamon the stub? about 15
• Bugscope Teamand here is another one, with some other little water flora growing on it
• Studentwho is tutu0422
• Studentlike turtles
• Studenthow does the larvae swim?
  Bugscope Teamprobably swims poorly; usually they are fairly stationary
• 3:45 pm
• Bugscope Teamthis is what the inside of the microscope looks like
• TeacherCan we switch controls again to caleb for a few minutes?
• Bugscope Teamyou can see the stub, which is 1. 75 inches in diameter
• Bugscope Teamsure!
• Bugscope Teamthe electron beam comes from above and the 2ndary electrons are collected in the cage upper right
• Bugscope Teami don't see a caleb logged in now?
• Bugscope Teamwhat is Caleb logged on as?
• Bugscope Teamcleave i just gave you control
• Bugscope Teamwe gave control to cleave

• Bugscope Teamthis is the head of the caddisfly larva
• Bugscope Teamthe mouth is kind of dirty

• Bugscope Teamthis is cool!

• Bugscope Teamthis is one of the diatoms
• TeacherI guess you guys figures it out.
• Bugscope Teamso lovely!

• Bugscope Teamdiatoms have silica shells; that is what we're lookin' at now

• Bugscope Teamthere are lots of diatoms on the samples today
• 3:50 pm

• Bugscope Teamsee the micron bar? 2 microns is the length of a single bacillus
• TeacherWe are having a changing of the guard now. A new batch of kids will arrive. I will refresh the computer screens so that the new kids can log in with different names
• Studentwhat are diatoms again?
  Bugscope Teamthey are little single-celled silica-shelled organisms that live in the water
• Bugscope Teamthis is high mag, and because we are fairly far away from the electron source we do not get the best resolution

• Bugscope Teamok, good idea to refresh the screens (F5)

• Bugscope Teamwhat those were kids?

• Bugscope Teamdiatoms are algae -- they are phytoplankton, and some of the larvae/nymphs we see today feed on them

• 3:56 pm
• Studentwhat is that
  Bugscope Teamif you click on the scale bar you will see what preset we are on
• Bugscope Teamthis is a stonefly, its an aquatic insect
• Studentcool thanks
• Studentthanks alot team we had a great time got to go tie knots. We learned Alot! Thanks, Cleave
• Bugscope Teamthank you, good job!
• TeacherCleave is heading out, so please switch the controls to me for a bit?
• Bugscope TeamBye Cleave!
• Bugscope Teamyou've got control now cheryl
• Bugscope TeamCheryl you are the Supreme Commander

• Studentthat's so cool it looks awsome
  Bugscope Teamthis is a bunch of debris at the mouth area

• Bugscope Teamglad you dig it, these are live images from an electron microscope
• Bugscope Teamcherly is controlling the scope as we speak (or type)
• Bugscope Teamcheryl i mean, sorry
• Bugscope Teamlike dirt probably
• Bugscope Teamthis is one of the stonefly nymphs
• TeacherI didn't even notice

• Bugscope Teamwell he got all of the letters right

• Bugscope Teamnow we see some of the palps

• Studenthow does the larvae swim
  Bugscope Teamthey are said not to swim well
• Bugscope Teamthese dudes eat mostly algae and plants that are decaying
• 4:02 pm

• Studentwhat are diatoms
  Bugscope Teamdiatoms are phytoplankton that have silica shells
• Studentcool
• Bugscope Teamthey are eukaryotic plants
• Bugscope Teamthere are many different and cool-looking shapes
• Bugscope Teamthese stoneflys are very susceptible to pollution, so if you seen them in a creak or water, it's likely the water is clean
• Studentthey are so cool
• Studentneat
• TeacherThis next session is much smaller. Can we switch contorls to mpysden?
• Studentyep its so neat
• Bugscope Teamthese stonefly's also molt many times, some molt 12-33 times

• Bugscope Teamand their final molt usually ends with them becoming terrestrial adults, land based
• Bugscope Teamone of the references I found says flatly that stonefly nymphs do not swim -- they crawl

• Bugscope Teammpysden, you've got control now

• 4:07 pm
• TeacherAlso can I log out an log myself back in on a different computer? I am having some computer troubles
• Bugscope Teamsure

• Bugscope Teamwelcome back cheryl
• StudentPhew, let's hope the darn "script problem doesn't happen on this machine."
  Bugscope Teamhmmm, i hope not too. if so let us know
• Bugscope Teammpysden, still has control
• Studentwhat are the grape liike things?
• StudentHe's lost the control screen
  Bugscope Teamtry refresh (F5)
• StudentThis is Cheryl , I sat down on mpysden's computer
  Bugscope TeamCool!
• Bugscope Teamokay, so who wants control? right now mpysden login has it
• Studentnow its mpysden again
  Bugscope Teamsuch an awkward name -- how do you pronounce it?
• Bugscope Teamyou may need to refresh your screen (F5)
• StudentIt looks like there is some kind of a hook think coming out of the neck area
  Bugscope Teamhmm, yeah, it looks to me like an antenna of some kind?
• StudentLet's keep the controls with mpysden.
  Bugscope Teamwill do
• Studentyes it does

• Bugscope Teamoh wait, maybe that hook is a claw?
• Bugscope Teamyeah it is hard to tell
• Bugscope Teamand most of the claw base is under all those plant fibers...
• 4:12 pm
• Studentwhat r those ball things by the hook
  Bugscope Teamwe think those are some kind of aquatic organisms that lives in the water

• Studentok thanks
• Bugscope Teamthey are something like vorticella

• Bugscope Teamif you look at them upclose they are likely a filterfeeder of some sort
• Bugscope Teamthis is one of the claws of the caddisfly larva
• StudentCan you switch controls to ehibbing96?
  Bugscope Teamthey have control
• Bugscope Teamthe little hairs are sensory

• Studentthats so cool

• Studentwhat is that
  Bugscope Teamthat was one of the claws

• Studento ok

• 4:17 pm

• Bugscope TeamI think they probably have frond-like things that stick up out of this part

• Studentso cool
• Studentwhat is that?
  Bugscope Teamwe are looking at the vorticella -- or whatever this organism is

• Bugscope Teamand we are so close we can't see too much

• Bugscope Teamthe sample we are looking at is far from the polepiece so we can see the insects at low mag
• Studentthats is the caddisfly accsessory limbs
  Bugscope Teamyes those were limblike projections -- comparable perhaps to prolegs on a caterpillar

• Bugscope Teambut when we get up very close we do not have as good resolution as we would if we were closer

• Studentnow it isnt

• Bugscope Teamgood job focusing
• Studentok
• Studentwhat is this pore thinkg?
• Studentis that the eye
• Bugscope Teamthis is one of the palps, and these are likely chemossensors
• Studentok

• Bugscope Teampalps are accessory mouthparts

• 4:22 pm
• Bugscope Teamthat help insects feed by manipulating food toward the mouth
• Studentcool
• Bugscope Teamthere are usually two sets of palps, sometimes called pedipalps
• Bugscope Teammandibular and maxillary palps

• Bugscope Teaminsect mouths usually open side to side, not like ours
• Studentis that a slug
• Studentlooks like a red blood cell
  Bugscope Teamit is about that size RBCs are usually 8 to 12 microns in diameter
• Bugscope Teama large diatom -- you can see one of the smaller ones that look like sarcophagi to the lower left

• Bugscope Teambunch more diatoms

• Studentto much things to see

• Bugscope Teamthe caddisfly larvae builds a shell for itself out of debris, and the diatoms stick to that
• Bugscope Teamkind of looks like a slug

• Studentis that a flea

• Bugscope Teamthese are meanlooking little dudes
• Studentyes they are

• StudentIt looks like the caddisfly has just tiny little eyes

• Studentok cool

• Bugscope Teamthe eyes are much like simple eyes on a caterpillar

• Bugscope Teamthose are called 'stemmata'
• 4:27 pm
• StudentIt doens't look like the caddisfly spends much time cleaning it's head
• Bugscope Teamlotta juju on the surface of the caddisfly -- yeah -- makes it crunchy to eat
• Studentis that a whisker
  Bugscope Teamthey are comparable to whiskers
• Studentyummy
• Studentyummy

• Bugscope Teamthey are often mechanosensory like cat or rat whiskers
• Studentcrunchy were do they have that

• Bugscope Teamsetae can be touch-sensitive, or hot/cold discriminating, or smell/scent sensitive
• Studentis that dust
  Bugscope Teamsome of it is debris that settled on it when we critical point dried it

• Studentthis is so fun
  Bugscope Teamyay!
• Bugscope Teamthis is one of the stone cocoons they build
• Bugscope Teamif you go up close you can see that there is a kind of web that holds it together

• Studentooh that's pretty
• Studentwhat are these hairs on it
  Bugscope Teamantennae are usually what insects use to get info about their environs, and the tiny setae help with that
• Studentis that hair?
  Bugscope Teamso they are hair-like but may have other functions
• 4:33 pm

• Studentcreepy
  Bugscope Teaminsects can look creepy up close like this. they can also seem creepy without the microscope though
• Bugscope Teamserious mandibles
• Bugscope Teamsharp

• Studentthats looks so delectebile
• Bugscope Teammost stonefly nymphs eat decaying plant material and algae, but some are predatory

• Bugscope Teamsee the sharp mandibles?
• Studentit smileing
• StudentCan we switch controls one last time to tutu?
• Studentits smileing
• Bugscope Teamtutu is the supreme ruler
• Studenthow far can i zoom in?
  Bugscope Teamkeep focusing as you go
• Bugscope Teamyou can tell that neither Cate nor I made this sample stub

• Studentall hale tutu

• Bugscope Teamit's really whether there is anything to see

• StudentWhat do you mean we can tell neither Cate nor you made the sample stub?
  Bugscope TeamMark did the critical point drying for us and mounted the samples, and we appreciate it. But we usually try to make the heads all go to the north so they are not upside down
• Bugscope Teameeeuuwww
• Studentwow

• Studentits a blackberry
• 4:38 pm

• Bugscope Teamthese are tiny setae on one of the palps, and they are quite different from what we see on terrestrial/flying insects

• Bugscope Teamthese are in about the same position as prolegs in a caterpillar
• Studentcool

• Bugscope Teamthey may function kind of like legs to help the caddisfly larva hold itself inside its case
• Studenti want more limbs
  Bugscope Teamheh

• Studentdoes this bug have a rough exosceliton at 3000X or is it just dirty
  Bugscope Teamthis is 71,000x, and it is a little dirty
• Studenti think its just duirty

• Bugscope Teamthis is 35,793x
• Bugscope Teamwe are looking at those tendril-like limbs

• Bugscope Teambacteria!

• 4:43 pm

• Studentno its 21216x
  Bugscope Teamnow you're way hi

• Bugscope Teame. coli looks like this

• Bugscope Teamsorry I keep dropping the mag a bit

• Bugscope Teamthis would look much better if we were very close to the sample, but we are not today
• Studenthow big is the origonal bug
  Bugscope Teamthere are a few, from a centimeter to maybe 2
