• 8:46 am
• Bugscope Teamhello!
• 8:55 am
• Bugscope TeamIt's almost 10 here, almost 9 there. So I'm quite early. Have a good session!
• 10:12 am

• Bugscope Teamhello lebouef, welcome to bugscope
• Bugscope Teamwe are setting up for a session in 43 minutes
• Guestcoolbeans

• 10:17 am

• 10:24 am
• Bugscope TeamHey kids
• Bugscope Teamor, um, alex
• Bugscope Teamhi annie

• Bugscope Teamwe got annie! better than milk
• Bugscope TeamSession starts in 33 minutes, right?
• Bugscope Teamno scott today
• Bugscope Teamyep
• Bugscope TeamHe is in NYC, right>
• Bugscope Team?
• Bugscope Teamyep

• Bugscope TeamI will be around, back when the session starts. I will let your set up in peace
• Bugscope Teamokay, thanks annie
• 10:29 am

• Bugscope Teaminsect antenna

• 10:34 am
• Bugscope Teamhi Mrs. Harsh, welcome to bugscope
• TeacherHi... we are using internet explorer.. the other was blocked... will this be a problem

• Bugscope TeamIE will for fine, no prolem

• Teacherso what was the picture that had all the holes
  Bugscope TeamThat was the leg of the centipede, we were wondering if they were poison pores, but we don't think they are
• 10:40 am
• Teacherhow long does it take for the download? I clicked on driving and it still says wait whil comman executes
  Bugscope TeamIt shouldn't take very long. We are still setting up the session, so if you can hold off for a few minutes, then you can drive
• Teacherwe have 12 laptops set up for the students to use
  Bugscope Teamthat is just fine, having 12 kids login is perfect

• Teacherok
• Bugscope TeamOnce you give you control, Mrs. Harsh, the delay from click to movement is no more than a second or two...
• Bugscope Teamwaterbug!
• Bugscope TeamOnce *we* give you control I mean...
• Bugscope TeamActually, a water boatman
• Bugscope TeamThese are the back legs that the bug uses to paddle through the water

• Bugscope Teamokay, we are done with preset, i just unlocked the session
• Bugscope Teamyou should see controls on the right side
• Bugscope Teamgive it a try, any questions let us know
• Bugscope Teamwhen using navigation, click to center is much easier to control than click to drive
• 10:46 am
• Bugscope TeamMrs. Harsh, you must be away from keyboard? When you come back, go ahead and try controlling

• Bugscope Teamgood job mrs. harsh! click once to start moving, click again to stop

• Teacherok that works.. do that each time?
• Bugscope Teamwell, click to CENTER is much easier to use
• Bugscope Teamwhen you get lost, you can always click on one of the preset (lower right)
• Bugscope Teamthat'll take you to the preset
• 10:52 am
• Bugscope Teamcan you try clicking on a preset?
• Bugscope Teamah, here are the students.
• Bugscope Teamwelcome to bugscope!

• Studentwhat is that?
  Bugscope Teamthis is a shell, with a small diatom on it
• Teacherok ... we have 15 computers
  Bugscope Teamthats pretty cool
• Bugscope Teamwelcome students, you are looking at live images from an electron microscope that your teacher is controlling over the internet
• Teacherwhere would a diatom come from
  Bugscope Teamwell the diatom is on a shell. The shell was probably from a stream, where diatoms flourish
• Bugscope Teamplease go ahead and ask us any questions you have. Annie is an entomologist, Cate is a microscopist, and I am a sysadmin
• Teacherwe caught these in a wooded area.... could they be in a ditch?
  Bugscope Teamwell diatoms are silica based and are like plankton- other aquatic things eat them. Maybe some stream runoff got into the ditch or whatever was living in the shell moved it? Normally you wouldn't see diatoms in a wooded area

• Studentwhat is that
• Studentwhat is that?
• Bugscope TeamThis is an Earwig
• Bugscope TeamThe head of an Earwig
• Studentwhat does it do?
• Studentwhat does it do
• Studentwhat does it do

• Studentwhat is that?
  Bugscope Teamthese are pores that are found along the back legs of a centipede. Maybe they are breathing holes called spiracles. We aren't 100% sure
• 10:57 am
• StudentWhat is this?
• Studentwhat are the wholes for?
• Studentwhat are the holes
• Bugscope Teamearwigs are nocturnal, and they often hide in small crevices
• Studentwhat is this?
• Studentwhat is that
• Bugscope Teamearwigs are plant eaters, but they will also eat other insects
• Studentdo they live in your ear?
  Bugscope TeamNo, there is a legend that earwigs would crawl into the ears of sleeping people and eat their brains
• Studentare those holes?
• Bugscope Teamthere are some earwig fossils from 208 million years ago, so it is a very OLD insect...
• Studentwhat are the spike looking things?
  Bugscope Teamthose are called setae (pronounced see-tee), they help it to sense its environment, like cat whiskers
• Bugscope TeamBut that is not true.
• Studenti hope not
• Teacherdo they eat live plant material or rotting logs? we found them in rotting logs
  Bugscope TeamThey eat decomposing matter, like leaves, bark, etc. They live in dark, moist places. They also are significant pests of landscape plants and flowers.
• Bugscope Teamhello
• Bugscope TeamThe legend of earwigs eating brains comes from the time when people slept on straw mattresses. The earwigs would hang out in the mattresses and people would find them in their beds with them. Earwigs like places like piles of leaves and straw.
• StudentWhat is inside the holes?
  Bugscope Teamif they are spiracles, or breathing holes, they are connected to a trachea which runs along the entire body, supplying the body with oxygen

• Studentwhatis that?
• Studentwhere did they come frome and do they have bones
  Bugscope TeamNo insects or arthropods have bones. They have an exoskeleton made of tubes of chitin. Their muscles and organs are inside the exoskeleton
• Bugscope Teamspike are called setae
• Studentwhat do they use them for
• Studentwhat is that?
• Studentwhats that one huge spike?

• Studentwhat are the hairs on it?
  Bugscope Teamthose are setae, they help it feel its environment
• StudentWhat part is this?
• Studentwhat are the sencory organs
  Bugscope TeamInsects and arthropods can see with their eyes, they taste using setae on their mouths, antennae, and feet; the feel using different kinds of hairs (setae) that stick through their exoskeleton; the hear using still OTHER setae that detect vibrations.
• Studentwhat part of the body are we looking at?
  Bugscope Teami think we are looking at a segment of a leg, where it bends.
• Studentis that its eye
• 11:02 am
• Studentis that a crads?
• Studentare we still looking at an earwig?
• Studenthow big is the entire insect???

• Bugscope Teamthere are spikes to make sure it doesn't overextend its leg

• Studenthow does the hairs help the environment??
  Bugscope Teamthe hairs help the insect feel and then there are special hairs on other insects that help them taste/smell, stick to walls, help them swim better
• StudentIs that its led?
• Studentwhat is this?
• Studentleg
• Studenthow many legs do it have?
  Bugscope Teamit's missing quite a few that fell off, but it doesn't look to have a 100 legs
• Studenthow do the holes help it?
  Bugscope TeamI think that these holes excrete a nasty toxic substance when the centipede is disturbed. This helps to defend the centipede.
• StudentHow many does it have?
  Bugscope TeamCentipedes have one pair of legs per body segment. It looks like this centipede has 8 body segments (I can't see the end from here). So, 8x2 is 16. 16 legs.
• Studentwhat is that next to it?
  Bugscope Teamlooks like there is a broken off leg and maybe a part of a mosquito

• Studentwhat are the holes for on is leg?
  Bugscope TeamI think those must serve a defensive function--emitting a toxic compound to deter predators.
• Studenthow big is the brain
  Bugscope TeamPretty small. The brain of this centipede is probably not much bigger than the letter on in "who's online" at the top lef tof your screen

• Studentwhat do they eat?
  Bugscope TeamCentipedes are all predators. They eat other arthropods. Well, really they will eat anything smaller than them. Some of the very large centipedes will eat baby mice!
• Bugscope Teamthe bubbly background is carbon tape, and the lighter patches are the silver paint

• 11:07 am
• Bugscope Teamthe is the edge of the stage
• Studentwhat kind of gold?
  Bugscope Teamheh, the real kind. :) it's gold-palladium though, so it's mixed, and it's also very think like a spray, cate can give you more detail

• Studentwhoes fallen
• Studenthow long is the lifespan of it?
  Bugscope Teamcentipedes have a long lifespan of around 5 years
• Studentwhat are the holes forr?
  Bugscope TeamThe hole secrete a defensive compound.
• Studenthow do the hairs help them?
  Bugscope Teamthey are sensory hairs, called setae, and they are like it's skin. without those setae they wouldn't be able to feel anything
• Studentwhat is the head look like?
  Bugscope Teamthe head is really flat, and it's very hard to tell it is a head, but is has a pair of antennae on it that look slightly different than the legs
• Studenthow does it age?
  Bugscope TeamCentipedes hatch from eggs and molt into larger and larger centipedes throughout its life. Spiders do a similar thing.
• Studentwhat part of the body is this?
  Bugscope TeamThis is the posterior end.
• Bugscope Teaminsects and bugs have a hard exoskeleton, which doesn't have any nerves in it, so those setae stick through the exoskeleton, to nerves underneath, that's how they feel things
• Studenthow old can they get
• Studenthow big does it get
  Bugscope TeamThe largest centipedes can be 7-8 inches long. Most centipedes are not that long though.
• Teachery does it hav those bumps on it
  Bugscope Teamthe carbon tape? They probably had air bubbles in the processing
• 11:12 am

• Studentwhat kind of enviorment does it live in

• Bugscope Teamclick again to stop! yay, just got it
• Studentwhat is that?
  Bugscope Teamthere is a screw in the stage
• Studentwhat is that
• Teacherwhat is this
  Bugscope Teamwell, this is the edge of the sample, you can see one of the screws that holds the sample in place
• Bugscope Teamif you want to move to a different insect mrs. harsh, try click on a preset
• Studentis there a limited number of people who can log in
• Bugscope TeamIt is really easiest to use the click to drive command--MUCH easier to use!
  Bugscope Teamclick to center...
• Studentwhats in the bumps
  Bugscope Teamthose are bubbles in the sticky tape we put the bugs on

• Bugscope TeamGAH
  Bugscope Teamno problemo :)

• Bugscope TeamClick to center!!!

• Bugscope TeamBeetle head
• Studentannie, what is your job?
  Bugscope TeamI am a post-doctoral researcher at the University of California. I am an entomologist.
• Studentwhat is your job?

• Studentwhat is a entomoligist ?
  Bugscope TeamAn entomologist is a scientist that studies insects (and other arthropods)

• Bugscope Teamannie is our bug-ologist :)

• Studentwhats ur jub alex
  Bugscope Teami am a systems adminitrator. i setup/fix and generally pamper computers...
• Bugscope TeamI am a microscopist here and alex is our computer-ologist
• Studentjob*
• Bugscope TeamWe let people who study spiders and ticks and centipedes call themselves entomologists as well
• Bugscope Teammost insects have these kind of claws: for eating, grabbing stuff, climbing stuff, etc
• Studentdo insects have a heart
  Bugscope TeamYes, they have a series of hearts on the top of their bodies (under their wings). Insects have an open circulatory system, which means that all of their organs just hang out in the blood, because insects don't have veins or vessels.

• Studentwhat is your job alex?
• 11:18 am

• Bugscope TeamAlex is the nicest and most helpful sysadmin every..
• Bugscope Teamever

• Studentwhere are there blood
• Studentwhere is their blood
  Bugscope TeamIt is all sort of hanging out inside their bodies. It is the watery looking stuff that comes out when you step on an insect.
• Studentwere is there blood
• Studentto alex what is your job?
  Bugscope Teami'm an IT sysadmin, a computer geek. like geek squad except i work for the university of illinois
• Studentwhy is the blood green
  Bugscope TeamSome insects have greenish blood and some have clear blood. It sort of depends on the insect. Green insects have green blood. Ladybugs have yellowish blood. Cockroaches have clearish blood.
• Bugscope Teamthanks! i like people, that's why. i like people more than computers. ;)
• Studentwhy is there blood green?
• Studentwhat is the difference between an entomologist and an arthopologist?
  Bugscope TeamAn arthropologist would study all arthropods--crabs, spiders, ticks, insects, millipedes. An entomologist focuses more on insects (although they also study centipedes and millipedes, spiders, ticks and mites.) Essentially, if you study anything that is an arthropod that is not a crustacean, you can be called an entomologist. It would be hard to study ALL the arthhropods
• Studenthow long is its lifespand
  Bugscope Teamthat depends on the type of beetle it is. I'm not sure what type this is, but they can live form weeks to years
• Studentthat is cool, bout there different blood colors!!!!
• TeacherSome computers are getting kicked off and not being able to attend the live session
  Bugscope TeamSorry about that, I just fixed it, try logging in again please
• Studentdo they have teeth
  Bugscope Teamthey have a pair of jaws, but no teeth

• Studentwhats a bore beetle
  Bugscope Teamit's a type of beetle that bores into things like wood or plant matter

• Studentcan we control it

• 11:23 am
• Studentmay i control?
• Studenthow do they eat???
  Bugscope TeamMany insects just take a bite and chew--just like we do. Some insects have sucking mouthparts--they have a completely liquid diet.

• Studentare all beetles simaliar or are they all diferent
  Bugscope TeamThey share some characteristics that group them all together. They have complete metamorphosis and the all have "shells", hardened front wings.
• Studentdo they have a brain
  Bugscope TeamYes, they all have brains.
• Bugscope TeamSome people would call them wood-boring beetles
• Bugscope Teamanyone can control, mrs. harsh just let us know which students you want us to give control to

• Teachercan you give ryan control
• Studentwhat is a ladybug palp?
  Bugscope Teamladybugs have palps near their mouths, they are kind like tongues in that they can taste, or even smell, food. the palps also help direct food into the mouth as well
• Bugscope Teamryan now has control

• Bugscope Teamryan, give it a shot, try clicking on a preset or changing the magnification

• Studentwat is the thing in the right corner
• Bugscope Teamgood work ryan! you are controlling a $700,000 electron microscope over the internet!

• Studentdo they have a nose or antennae
  Bugscope Teamthey do have antennae, but not noses, insects smell with the setae (hairs), some setae are chemosensory and can smell things

• Studenty do there legs look so hairy?
  Bugscope TeamInsects are covered with hairs, which we call setae. The setae on the leg help the insect to sense the surface it is walking on. Some of those short hairs also help the insect to clean other parts of its body.

• Studentwhat is that
  Bugscope Teamthis is a leg of the beetle, with lots of little hairs, or setae, sticking out

• Studentwhat are the little bumps?

• Bugscope Teamyou are doing great ryan
• Studentwhat are those rain drop shaped things on its legs
  Bugscope TeamThose were stout little setae that the beetle uses to clean itself (or to defend itself in some cases)

• 11:28 am

• StudentWhat is a Aphid Head
  Bugscope Teamaphids are pests that destroy plants.

• Studentwhat is that
  Bugscope Teamthis is the shell you sent us, and we found there was a centipede crawling out of it
• Studentwhat is that
• Studentis it its shell?
  Bugscope TeamNo this is the shell of a snail. The centipede was either eating the snail or living in its shell
• Studentwhy do they look
• Teachercould you let shell&brit drive
  Bugscope Teamdone
• StudentWhat is that long thing coming out of the shell?
  Bugscope TeamThat is a centipede

• Studentwhat is the stuff in the background
  Bugscope Teamwe put the bugs on sticky tape so they stay still, that tape has some bumps in it

• Studentwhat is that
• Studentwhat is this
• Bugscope TeamThis looks like a little bark beetle

• Bugscope Teamthis is a bug head!!! the head of a wood-bore beetle
• Bugscope Teamor a bark beetle, annie knows better
• Studentwhat are those paddle things coming out of it
  Bugscope TeamThose are the antennae
• Bugscope Teamcheck out the compound eye on the right side
• Studentwhere is the mouth
• Bugscope TeamHe was probably living in the rotten log--decomposing the wood.
• Studentwhat kind of bug is this ?
  Bugscope TeamThis is something that looks like a bark beetle to me. It is a wood-boring beetle, like Alex said.
• Studentwhat are those paddle shaped things?
• Bugscope Teamthe compound eye is made up of many individual facets called ommatidia, each one with a lens in it
• Teacherare those his eyes? what are the things under them
  Bugscope Teamthe only eye we can see here is the compound eye on the right, it's bumpy

• 11:33 am
• Studentwhy are they so hairy?
  Bugscope Teamthose hairs are setae, they act like skin: to feel things. so the more hairs the better they feel

• Studentdoes a bore beetle have eyes
  Bugscope Teamyes they have compound eyes found on either side of its head
• Studentdoes the hair on his face help it to eat
  Bugscope Teamyes, you are getting it! some of the hairs near the mouth might help it taste or smell it's food

• Studentthis that a moth?
  Bugscope TeamNope it is a beetle "chest"--called the prothorax
• Bugscope TeamNow, of course, there are hundred and thousands of species of small brown beetles that live in rotten log, so it may not technically be a true bark beetle.
• Studentwat does it eat?
  Bugscope TeamIt bores in wood. Many of these kinds of beetles introduce a fungus that breaks down the wood. The beetles actually feed on the fungus.

• Studentwhat are we lokking at now?
  Bugscope TeamThis is a corixid water bug.
• StudentWhat are we looking at now?

• Bugscope Teamedge of the world!!
• Teachercan you let caitlin
  Bugscope Teamdone. caitlin has control now
• Bugscope Teamoops, drove off the edge a little bit there :)
• Studentis that a labbybug

• Studentwhat is that
  Bugscope TeamIt is the palp of a ladybug
• 11:38 am
• Bugscope TeamThis is now the ladybug
• Studentwats that
• Studentwhat part is this?
  Bugscope Teamthis is inside the ladybug palp. These are kind of like tastebuds
• Studentis that the little black bugs we see in ponds like floating water??
  Bugscope TeamThis is not. This is just a plain-ol' ladybug

• Studentwhat are those spiney things
• Studentwhat body part are we looking at/?
  Bugscope TeamIt is part of the mouth
• Studentwhat is the spikey things for
  Bugscope Teamthose are probably sensory things on the palp, the things that smell/taste food

• Bugscope Teamthis is a closeup of a ladybug palp, it helps it taste/smell food and direct food into it's mouth

• Studentcan a ludybug have kids?
  Bugscope Teamif they didn't then there wouldn't be any more ladybugs in the world

• Studentwats that

• Bugscope TeamCOOL! this is a compound eye, the bumps are called ommatidia, they each have an eye lens in them

• Teachercan you let twitch drive
  Bugscope Teamgot it

• Bugscope TeamFemale ladybugs lay eggs, just like a chicken ;)
• Studentwhat is that
• Studentis that a butterfly
  Bugscope TeamThis is the "foot" of a butterfly
• Studentthis there head?

• Studentare those scales
  Bugscope Teamright on smurf, you got it, those are scales underneath

• StudentAnnie, do you like doing this?
  Bugscope TeamYes, Bugscope makes me think creatively about insects. I enjoy explaining entomology to students.
• 11:43 am
• StudentAlex,Is your job fun?
  Bugscope Teamaffirmative B-)
• Studentwhat is your research, Alex?
  Bugscope Teamcomputers

• Studentwats that

• Studentis that the outer scales

• Bugscope Teamokay, nugget has control now
• Studentwhat is your research,Annie

• Studentthis is a wing wrig?
• Studentwhat is that
• Bugscope Teamwell, this is a scale on a wing, yes

• StudentBye we have to go(:
• Bugscope Teamyou all did GREAT!
• StudentThank you soo much (:
• Studentwe are going to lunch yeb
• Studenti had fun. thanks for your answers. most of us are going to lunch. bye
• Bugscope Teammrs. harsh, all the chat and images from this session are saved to your member page: http://bugscope.beckman.illinois.edu
• Studentthanks for the answers guys! :)
• StudentByee we Have Too Go Too Lunch (:
• Bugscope TeamThank you all!
• Bugscope Teamthank you for using bugscope. we hope you all had fun
• Teachercan you let smurf dridr
• Bugscope Teamack, the correct webpage is: http://bugscope.beckman.illinois.edu/members/2010-014
• Bugscope Teamsmurf has control now
• Studentalex is your jod cool?
  Bugscope Teamtotally. cool as cool can be

• Studentwat dem spaces for
  Bugscope Teamwell, to keep the scale light and airy, those holes help to do that
• Bugscope Teamhere's more about the bugscope staff: http://bugscope.beckman.illinois.edu/who_are_we

• 11:48 am
• Bugscope Teamscales are cool. They have pigment granules that give them color along with the actual structure of the scales

• Studentdo they have a tummy
  Bugscope TeamThey have a digestive system, which is fairly similar to ours. It is a long tube that starts at the mouth and ends at the other end.

• Studentalex are you a bug docter?
  Bugscope Teamheh, no, i'm a computer doctor. i work with bugscope so that we have a techie around in case of any computer problems. but i've learned some many cool things about bugs, makes the job very very cool

• Studenthow small is salt
  Bugscope Teamcheck out the scale bar in the lower left of the image, one um = one micron = one millionth of a meter
• Teachercan julia drive
• Bugscope Teamso a salt crystal like this one is about 150 microns
• Studentdo you have a preset of a tick
  Bugscope TeamI don't think we have a tick today
  Bugscope Teamno we don't have any ticks today. sorry

• Studenthow many xs this magnified
  Bugscope Teamclick on the scale bar, it'll tell you
• Studentwhat is a junebug
  Bugscope TeamA junebug is a type of scarab beetle. They typically emerge in large numbers at the beginning of June. They are very buzzy and very attracted to porch lights. They all feed on plant roots.
• Studentok
• Studentwhat is a junebug?
• Bugscope Teamto find out the mag, click on the scale bar in the lower left of the image, cool info will show up on top

• Bugscope Teamin texas you must see a wide array of insects we dont see in illinois
  Bugscope TeamWest and south Texas are famous for their insects

• Bugscope Teamthe scope can magnify up to 600,000x, but for bugs we don't go much past 40,000x

• Studentcool
• Bugscope TeamThere are insects there that are not present any other place in the US.
• Bugscope Teamwe can see things as small as 1.2 nanometers
• 11:53 am
• Bugscope TeamA friend of mine wrote a paper all about the longhorned beetles of west Texas.

• Bugscope Teamcate, a nanometer is one billionth of a meter, right?
  Bugscope Teamyep
• Bugscope Teamthese are special setae that help the insect walk on walls
• Studentwhat is ladybug tenent do?
  Bugscope Teamthe tenent setae help the ladybug to climb walls. you know how they can climb walls upside down? that's the tenent setae helping them do that
• Studentwhat is a butterfly lifespand
  Bugscope TeamMost insects live a year from the time that they are a leg until they die as adults. During the cold months, the butterfly with hibernate.
• Studentdo you have a tick bug?
  Bugscope Teamwe dont have any ticks today
• Teacherdo insect have all the setae because they don't have good sight? these were found in logs so do they need them to get around in the dard
  Bugscope Teamyes, i've never seen an insect without setae. setae are used for sight, but also feeling, tasting, temperature, smelling, etc.
• Studentdo you have flys?
  Bugscope Teamthere was a fruit fly on here for today, but it blew off when I was coating it with the metal
• Bugscope Teamand these setae (tenent setae) help to climb. setae are way cool.
• Bugscope TeamInsects that live in dark places like logs or under the soil often have reduced eyes (some subterranean ants have NO eyes). Because it is so dark, they rely on their sense of smell and taste to find their ways around.

• 11:59 am
• Studenti got to to lunch bye guys
• Bugscope TeamAnd they smell and taste with those setae.
• Teacherwell it is lunch time... the kids have left.... thanks for a great time
• Bugscope Teamsee you julia, good work
• Bugscope Teamthanks mrs. harsh, you did great
• Bugscope TeamThe setae also protect the insect from the dirt and rocks--which could damage the cuticle and kill the insect.
• Bugscope Teamremember your member page, you can access it anytime, all the chat and images are saved there
• Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2010-014
• TeacherI would love to go and read all the questions now that I am not instructing them
• Bugscope Teamnice session. good work everyone
