• 12:31pm

• Bugscope Team hi
• Bugscope Team welcome to bugscope

• 12:37pm

• 12:44pm

• 12:49pm

• 12:55pm

• 1:05pm

• Bugscope Team Session is unlocked.
• Bugscope Team we are ready
• 1:10pm

• 1:33pm
• Bugscope Team cool diatoms, even if they are covered in CPD stuff
• Bugscope Team Hi Cate!
• Bugscope Team hi sly
• Bugscope Team ?
• 2:21pm
• Bugscope Team Hi cheryl!
• Bugscope Team welcome to bugscope!
• Bugscope Team Hi Cheryl!
• Bugscope Team we are ready for you anytime
• Bugscope Team This 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 Team let us know if you have any questions
• Bugscope Team yeah Cheryl you should try driving!
• 2:29pm
• Teacher Hi, this is Cheryl. I am still getting set up so running around for another few minutes.
• Bugscope Team ok, no problem, we are here and ready anytime you are
• 2:41pm
• Teacher I'm here. the kids will be here soon. What am I looking at on the neck area?
• Bugscope Team those are some kind of organisms that live in the water, like vorticella. we don't know just what they are
• Teacher So are they a kind of parasite of symbiotic thing?

• Bugscope Team well we think they are likely symbionts

• Bugscope Team they are much larger than vorticella. we have seen them before but are not sure what they are
• 2:46pm
• Bugscope Team welcome to bugscope tut422, muffin, grace, marie, etc
• Bugscope Team Vorticella 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 Team be sure to ask us questions about the samples or the microscope, or other things
• Bugscope Team this is a stonefly larva head
• Bugscope Team these aquatic insects have similar features to land based insects, but there are differences
• Bugscope Team these 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 Team these are considered nymphs
• Teacher The kids are arriving. I'm going to do intros and instructions and then we'll be ready to roll
• Bugscope Team and they are sort of like aquatic caterpillars
• Bugscope Team ok
• Bugscope Team ok sounds great
• 2:53pm

• Bugscope Team see the mouthparts?

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

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

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

• Student whats the big tube yhing
  Bugscope Team that's an antenna
• Bugscope Team these mostly eat dead plants and algae

• Bugscope Team but some of them are carnivorous

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

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

• Bugscope Team the shell, as Alex said, is called an exoskeleton

• Bugscope Team their exoskeleton is like a suit of armor
• Bugscope Team the setae stick through the exoskeleton to nerves underneath, that's how they feel things
• Student does it have an exoskeleton
  Bugscope Team yes it does!

• Teacher what is this?
• Student where does it live
  Bugscope Team all these insects are aquatic, so they live in water, streams, lakes, etc.
• 2:58pm
• Student what is that

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

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

• Student what color is it
  Bugscope Team hard 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

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

• Student what are all those fuzzy things?
• Student is that its back or its leg?
• Student is it dangeruos
  Bugscope Team we don't think they are dangerous, not to people
• Student wat cind of insect
  Bugscope Team it is a stonefly larva
• Bugscope Team the stonefly larvae are brown to yellow

• Bugscope Team stonefly's are larva for almost a year, then they are an adult for only a day, they reproduce, and then they die
• Student what are those

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

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

• Student nice
• Student what does it eat
  Bugscope Team they eat mostly algae and decaying plant material

• 3:03pm

• Bugscope Team this is another stonefly

• Bugscope Team one um = one micron = one millionth of a meter
• Student where are it's eyes?
  Bugscope Team they are on the sides of the head

• Bugscope Team you can see one of the eyes now
• Student is it the same animal
  Bugscope Team this is another of the same nymph of the stonefly

• Student cool

• Student what dose it eat
  Bugscope Team they eat algae and plant mater
• Student what is that thing

• Bugscope Team that is the eye!
• Student what are the tube things used for?
  Bugscope Team those are antennae, so they pick up chemical signals int he water, and vibration -- they are sensory organs

• Student what are those circles in the background?
  Bugscope Team well, here we are looking at a compound eye, those circles are the eye facets, called ommatidia

• Student cool
• Student what is this bug?
• Student so, they have claws, but do they use them to climb or eat ,like humans?
  Bugscope Team yes 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
• Student what does it eat
  Bugscope Team algae and decaying plants

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

• Bugscope Team some stoneflies eat other insects

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

• Bugscope Team this is a mayfly larva now
• Bugscope Team we had landed on the jaws
• Student what does it eat
  Bugscope Team plants and decaying material
• Student what do they use the 3 tails for?

• 3:08pm
• Student are those the ribs?

• Student what are those flat things on the head
• Student where are the gills?

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

• Student what is it?
• Student what are the stone things
• Teacher Are these the gills?

• Student dum de dum
  Bugscope Team heh
• Student are those legs
  Bugscope Team yeah, we think those are prolegs

• Student is that it's lungs?

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

• Student are these rocks
  Bugscope Team no rocks here i'm pretty sure

• Student what are those tube things?
  Bugscope Team those are cerci

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

• Student why does it have 3 tails
  Bugscope Team probably helps it to maneuver in the water

• Student is that algae on it's tail or whatever?
  Bugscope Team we think so, yes, there is a lot of algae and diatoms on these critters..
• Bugscope Team cerci 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 Team the cerci have little anchors on them that may help them attach to the substrate

• Student Thanks!
• Student so is this supposed to be like email

• Student h]
• Student what do they eat
  Bugscope Team they eat plant matter mostly
• Student hi
  Bugscope Team Hi Megan!
• 3:13pm
• Student what are those three tube things
  Bugscope Team those are cerci
• Student is this broken
  Bugscope Team yes, sorry
  Bugscope Team yeah looks like it broke. Limbs can break easily once the insect is dead because they are dried out
• Bugscope Team some mayfly nymphs are detritovores, and some scrape food of of surfaces, mostly algae and organic material in the water

• Bugscope Team this is the head of a large mayfly nymph

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

• Bugscope Team you can see the compound eye, and you can see one of the antennae
• Student what does detritovores mean
  Bugscope Team it means they eat detritus, which is decaying material in the water

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

• Student the antenne, or whatever it is look like turnips
  Bugscope Team yeah they do!
• Bugscope Team the facets of the eye are called ommatidia
• Student is this the head?
  Bugscope Team yes it is!
• Student is a compound eye like lots of eyes put together?
  Bugscope Team yes it is, and it gives the insect good peripheral visiion
• Bugscope Team and Marie those are antennae
• Bugscope Team yeah, compound eyes are really cool. it's like seeing a thousand different images at once
• Student what is the fuzzy stuff between the eyes
  Bugscope Team well, some of it might be diatoms or decaying plant matter
• Student that eye is big under magnification, but how big is it on a human scale?
  Bugscope Team look at the scale bar in the lower left, that'll tell you true size
• Student where do they live
  Bugscope Team they live in streams, on rocks
• Student Thanks for doing this Cheryl!!!
• Teacher My pleasure!

• Student are those it's feet?
  Bugscope Team those are tiny setae

• Student what are those pointy things on the stonefly larve?
  Bugscope Team sorry not sure which pointy things

• 3:19pm

• Bugscope Team those are sensory setae, we think

• Student creepy
• Student this is fun scot
  Bugscope Team yes it is for us too!
• Bugscope Team what we see now are palps
• Student what is this
  Bugscope Team this is a stonefly nymph head
• Student is that his mouth
  Bugscope Team yes this is the mouth of a stonefly nymph
• Student on its mouth
  Bugscope Team there is a lot of detritus -- stuff that filtered out of the water
• Student weeee do de weeeee
• Student what are the pointy parts on the outside of the mouth? with fuzzy tips?
  Bugscope Team those were palps, which help insects taste and manipulate food toward their mouths

• Student wood
  Bugscope Team Valine one of the caddisfly larvae seems to have used wood to make its case.

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

• Student muffin your in charge

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

• Student are thosse little bugs?
  Bugscope Team those little pill-shaped dudes are bacteria -- some kind of bacillus
• Student is that the longest waundering antenne?
  Bugscope Team not sure sorry

• Bugscope Team nice muffin, going for the high mag huh?

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

• Student wow, nice job Muffin!

• Student what are we looking at?!
• Bugscope Team tutu0422 has control!!!
• Bugscope Team this is a closeup of the stonefly nymph antenna

• Student tutu your in charge
• Bugscope Team it looks like a pagoda

• Student And you are Aleshiah, Aleshiah :)
• Student http://bugscope.beckman.illinois.edu/axis_cache/current_image.php?expireCacheWith=1268515940038
  Bugscope Team is everything okay valine?
• Bugscope Team they are similar to antennae in terrestrial insects but up close they are different -- adapted for a water environment
• Student in the bleu Ferndale sweatshirt:)
• Student whats that
• Bugscope Team Valine hit refresh on your browser.
• Student what are the strip like thingies
  Bugscope Team those are various likely chemosensory setae
• Student see the holes? can we get some info?
  Bugscope Team i think those are holes where setae used to come out but broke off
• 3:29pm
• Student yes
• Bugscope Team land based insects would have holes like that, which would be for breathing, they are called spiracles
• Student hmm.........
• Student what are we looking at
• Bugscope Team see above the hole is another setae that is inside a similar hole
• Student somebody new should be on the controls soon.
• Student yum yum yum yum um
• Bugscope Team grace has control now
• Bugscope Team Grace is now the supreme ruler.
• Bugscope Team Grace you can choose from among the presets, take the mag up or down
• Bugscope Team drive off the edge of the stub...
• Student sly are you on the computer
  Bugscope Team I am also Sly when I am on the microscope.
• Bugscope Team let us know if you would like to see the inside of the microscope, briefly
• Student are you entemologists?
• Teacher Can we switch controls to Jebediah in about 2 minutes?

• Student very funny, scot!
  Bugscope Team gracias
• Student g
• Student The Brain?!!!!!!!!!!!!
  Bugscope Team this is one of the palps
• Bugscope Team jeb, you've got control now

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

• Student can antennae grow back?
  Bugscope Team they could if the insect molted; I am not sure these guys molt
• Student cheryl can i be on the contrels
• Student what is it?
• Student i sugest the thorax.
  Bugscope Team okay!

• 3:34pm

• Student Alex are you an entemologist
  Bugscope Team no, i'm a systems adminstrator, scott and cate are electron microscopist

• Student what insect is this?
• Bugscope Team Cate and I are electron microscopists.

• Student what is this

• Student You are quiet over there Muffin :)

• Bugscope Team roaches have these
• Bugscope Team too

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

• Student that's a lot of legs. those are legs ,right?
  Bugscope Team those are not technically legs

• Bugscope Team these have tiny setae on them

• Student Interesting?
  Bugscope Team these it is hard to tell whether they are chemosensory or mechanosensory

• Student is it dangerou
  Bugscope Team they're not dangerous to us
• Student how many legs do stoneflys have?
  Bugscope Team six
• Bugscope Team they may help detect water currents
• Teacher Can we switch controls to to valise?
  Bugscope Team Valine? Valise would be, like, a suitcase?
• Bugscope Team valine, right? valine has control
• 3:39pm

• Student i am going to watch for awile

• Student Cheryl, boxes keep coming up?
  Bugscope Team what are the boxes?

• Student who is tutu0422
• Bugscope Team try clicking on a preset, like no 23
• Guest werid
  Bugscope Team Veronica!
• Student what are they dangerous to
• Bugscope Team Valine you are at high mag. You can take it down if you want, or go to a preset.
• Student wow
• Guest what is it
  Bugscope Team this is a caddisfly larva
• Bugscope Team you are at 200,000x and there is not much to see there.
• Bugscope Team going this high mag won't work too well, we'd have to change the working distance.
• Student How is the weather over in Illinois?
  Bugscope Team cloudy, mid 40's, but it's a nice relief from the 0's we had a couple of weeks ago

• Student i am in control now
  Bugscope Team Yay!

• Bugscope Team these guys often build shells for themselves

• Student how many inst do you have
  Bugscope Team on the stub? about 15
• Bugscope Team and here is another one, with some other little water flora growing on it
• Student who is tutu0422
• Student like turtles
• Student how does the larvae swim?
  Bugscope Team probably swims poorly; usually they are fairly stationary
• 3:45pm
• Bugscope Team this is what the inside of the microscope looks like
• Teacher Can we switch controls again to caleb for a few minutes?
• Bugscope Team you can see the stub, which is 1. 75 inches in diameter
• Bugscope Team sure!
• Bugscope Team the electron beam comes from above and the 2ndary electrons are collected in the cage upper right
• Bugscope Team i don't see a caleb logged in now?
• Bugscope Team what is Caleb logged on as?
• Bugscope Team cleave i just gave you control
• Bugscope Team we gave control to cleave

• Bugscope Team this is the head of the caddisfly larva
• Bugscope Team the mouth is kind of dirty

• Bugscope Team this is cool!

• Bugscope Team this is one of the diatoms
• Teacher I guess you guys figures it out.
• Bugscope Team so lovely!

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

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

• Bugscope Team see the micron bar? 2 microns is the length of a single bacillus
• Teacher We 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
• Student what are diatoms again?
  Bugscope Team they are little single-celled silica-shelled organisms that live in the water
• Bugscope Team this is high mag, and because we are fairly far away from the electron source we do not get the best resolution

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

• Bugscope Team what those were kids?

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

• 3:56pm
• Student what is that
  Bugscope Team if you click on the scale bar you will see what preset we are on
• Bugscope Team this is a stonefly, its an aquatic insect
• Student cool thanks
• Student thanks alot team we had a great time got to go tie knots. We learned Alot! Thanks, Cleave
• Bugscope Team thank you, good job!
• Teacher Cleave is heading out, so please switch the controls to me for a bit?
• Bugscope Team Bye Cleave!
• Bugscope Team you've got control now cheryl
• Bugscope Team Cheryl you are the Supreme Commander

• Student that's so cool it looks awsome
  Bugscope Team this is a bunch of debris at the mouth area

• Bugscope Team glad you dig it, these are live images from an electron microscope
• Bugscope Team cherly is controlling the scope as we speak (or type)
• Bugscope Team cheryl i mean, sorry
• Bugscope Team like dirt probably
• Bugscope Team this is one of the stonefly nymphs
• Teacher I didn't even notice

• Bugscope Team well he got all of the letters right

• Bugscope Team now we see some of the palps

• Student how does the larvae swim
  Bugscope Team they are said not to swim well
• Bugscope Team these dudes eat mostly algae and plants that are decaying
• 4:02pm

• Student what are diatoms
  Bugscope Team diatoms are phytoplankton that have silica shells
• Student cool
• Bugscope Team they are eukaryotic plants
• Bugscope Team there are many different and cool-looking shapes
• Bugscope Team these stoneflys are very susceptible to pollution, so if you seen them in a creak or water, it's likely the water is clean
• Student they are so cool
• Student neat
• Teacher This next session is much smaller. Can we switch contorls to mpysden?
• Student yep its so neat
• Bugscope Team these stonefly's also molt many times, some molt 12-33 times

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

• Bugscope Team mpysden, you've got control now

• 4:07pm
• Teacher Also can I log out an log myself back in on a different computer? I am having some computer troubles
• Bugscope Team sure

• Bugscope Team welcome back cheryl
• Student Phew, let's hope the darn "script problem doesn't happen on this machine."
  Bugscope Team hmmm, i hope not too. if so let us know
• Bugscope Team mpysden, still has control
• Student what are the grape liike things?
• Student He's lost the control screen
  Bugscope Team try refresh (F5)
• Student This is Cheryl , I sat down on mpysden's computer
  Bugscope Team Cool!
• Bugscope Team okay, so who wants control? right now mpysden login has it
• Student now its mpysden again
  Bugscope Team such an awkward name -- how do you pronounce it?
• Bugscope Team you may need to refresh your screen (F5)
• Student It looks like there is some kind of a hook think coming out of the neck area
  Bugscope Team hmm, yeah, it looks to me like an antenna of some kind?
• Student Let's keep the controls with mpysden.
  Bugscope Team will do
• Student yes it does

• Bugscope Team oh wait, maybe that hook is a claw?
• Bugscope Team yeah it is hard to tell
• Bugscope Team and most of the claw base is under all those plant fibers...
• 4:12pm
• Student what r those ball things by the hook
  Bugscope Team we think those are some kind of aquatic organisms that lives in the water

• Student ok thanks
• Bugscope Team they are something like vorticella

• Bugscope Team if you look at them upclose they are likely a filterfeeder of some sort
• Bugscope Team this is one of the claws of the caddisfly larva
• Student Can you switch controls to ehibbing96?
  Bugscope Team they have control
• Bugscope Team the little hairs are sensory

• Student thats so cool

• Student what is that
  Bugscope Team that was one of the claws

• Student o ok

• 4:17pm

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

• Student so cool
• Student what is that?
  Bugscope Team we are looking at the vorticella -- or whatever this organism is

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

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

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

• Student now it isnt

• Bugscope Team good job focusing
• Student ok
• Student what is this pore thinkg?
• Student is that the eye
• Bugscope Team this is one of the palps, and these are likely chemossensors
• Student ok

• Bugscope Team palps are accessory mouthparts

• 4:22pm
• Bugscope Team that help insects feed by manipulating food toward the mouth
• Student cool
• Bugscope Team there are usually two sets of palps, sometimes called pedipalps
• Bugscope Team mandibular and maxillary palps

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

• Bugscope Team bunch more diatoms

• Student to much things to see

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

• Student is that a flea

• Bugscope Team these are meanlooking little dudes
• Student yes they are

• Student It looks like the caddisfly has just tiny little eyes

• Student ok cool

• Bugscope Team the eyes are much like simple eyes on a caterpillar

• Bugscope Team those are called 'stemmata'
• 4:27pm
• Student It doens't look like the caddisfly spends much time cleaning it's head
• Bugscope Team lotta juju on the surface of the caddisfly -- yeah -- makes it crunchy to eat
• Student is that a whisker
  Bugscope Team they are comparable to whiskers
• Student yummy
• Student yummy

• Bugscope Team they are often mechanosensory like cat or rat whiskers
• Student crunchy were do they have that

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

• Student this is so fun
  Bugscope Team yay!
• Bugscope Team this is one of the stone cocoons they build
• Bugscope Team if you go up close you can see that there is a kind of web that holds it together

• Student ooh that's pretty
• Student what are these hairs on it
  Bugscope Team antennae are usually what insects use to get info about their environs, and the tiny setae help with that
• Student is that hair?
  Bugscope Team so they are hair-like but may have other functions
• 4:33pm

• Student creepy
  Bugscope Team insects can look creepy up close like this. they can also seem creepy without the microscope though
• Bugscope Team serious mandibles
• Bugscope Team sharp

• Student thats looks so delectebile
• Bugscope Team most stonefly nymphs eat decaying plant material and algae, but some are predatory

• Bugscope Team see the sharp mandibles?
• Student it smileing
• Student Can we switch controls one last time to tutu?
• Student its smileing
• Bugscope Team tutu is the supreme ruler
• Student how far can i zoom in?
  Bugscope Team keep focusing as you go
• Bugscope Team you can tell that neither Cate nor I made this sample stub

• Student all hale tutu

• Bugscope Team it's really whether there is anything to see

• Student What do you mean we can tell neither Cate nor you made the sample stub?
  Bugscope Team Mark 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 Team eeeuuwww
• Student wow

• Student its a blackberry
• 4:38pm

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

• Bugscope Team these are in about the same position as prolegs in a caterpillar
• Student cool

• Bugscope Team they may function kind of like legs to help the caddisfly larva hold itself inside its case
• Student i want more limbs
  Bugscope Team heh

• Student does this bug have a rough exosceliton at 3000X or is it just dirty
  Bugscope Team this is 71,000x, and it is a little dirty
• Student i think its just duirty

• Bugscope Team this is 35,793x
• Bugscope Team we are looking at those tendril-like limbs

• Bugscope Team bacteria!

• 4:43pm

• Student no its 21216x
  Bugscope Team now you're way hi

• Bugscope Team e. coli looks like this

• Bugscope Team sorry I keep dropping the mag a bit

• Bugscope Team this would look much better if we were very close to the sample, but we are not today
• Student how big is the origonal bug
  Bugscope Team there are a few, from a centimeter to maybe 2

• Bugscope Team if we were trying to get really good image for research we would move much closer

• Student We are finishing up in about 2 minutes. This was fantastic! You guys are great!
  Bugscope Team cool Thanks!

• Student I've actually got a bucket of live bugs here that I can show these guys.
  Bugscope Team dinner

• Bugscope Team Alex had to go to the Outer World, get ready for his radio show tonight
