• 7:23 am
• Bugscope Teamhi there, welcome to bugscope!
• TeacherGood morning. I have just logged on in preparation for my third grade students to come to class at 8:30 eastern time, the we will switch classes at 9:15 and have another group for 40 minutes. Ok?
• Bugscope Teamthat sounds just fine
• Bugscope Teamdid anyone get back to you about the compatibility test results?
• TeacherMay I practice until they arrive. Yes it seems that it will be fine, maybe just slow, but mornings are always better than afternoon for internet connections
• Bugscope Teamsure, i just unlocked the session, you should see controls on the right side now

• Bugscope Teamtry using click to center instead
• Bugscope Teamalso, you can click on any preset to go there
• Bugscope Teamand if you need to focus, we can do that for you, click to drive and focus take up more network bandwidth, so you'll see some lag if you use those functions

• TeacherCan you drive for us too?
• Bugscope Teamsure, i can do that
• 7:28 am
• Bugscope Teamare you going to have the students login themselves, or are you going to type all the questions yourself?

• TeacherI would like for them to login and do it themselves if you think that would be ok.
• Bugscope Teamsure, that's the best really. also then, i would try to limit the logins to less than 10
• Bugscope Teamif the network is slow, having many logins will slow things down as well
• Bugscope Teamplease feel free to ask any questions you or the students may have
• Bugscope Teamthis is a beetle head
• Bugscope Teamhey alex
• Teacherok I will pair them up at computers, there are just 14 in each class and i have a projector that will be showing a large image on the wall for all to see. Can we do an intro together? I would type a hello and ask for any tips for the class when they arrive.
• Bugscope Teamsounds great mrs vignale, we are ready anytime

• 7:33 am

• Bugscope Teamthis is a caterpillar

• 7:38 am

• Bugscope Teamgood morning class, welcome to bugscope!

• Bugscope Teamcate is an electron microscopist, and i'm a systems administrator. but we have both been doing bugscope for years, and can tell you lots about the insects you are seeing
• Bugscope Teamplease go ahead and ask us any questions you have about what you are seeing

• Bugscope Teamwelcome to bugscope students!
• Studentwitch part is this
  Bugscope Teamthese are prolegs on a caterpillar
• Studenthow do you guys know all of these stuff
  Bugscope Teamwe learn by doing really. Sometimes we have an entomologist log in and help us with what we dont know
• Studentcan we see the proboscis
• StudentWhat is this?
  Bugscope Teamthese are hooks on the caterpillar that help it stay on leaves and such. They hook themselves in
• Bugscope Teamif you all did this enough youd know a lot about insects too, even if you arent a bug expert

• 7:43 am
• Bugscope Teammany insects have common parts though: exoskeletons, compound eyes, setae (hair like things), etc.
• Studentthat is a big micriscope
• Studentthis is cool
• Studentwhat is this picture
• Studentit looks like a rib right there
• Bugscope Teami believe the term for them is crochettes

• Studentoh
• Studenti wonder what this isi think it's bones
  Bugscope Teamwell, not bones, but they do look like bones don't they. insects don't have bones like we do. instead they have a hard outer shell called an exoskeleton
• Studentbugs are weird
• Bugscope Teamcaterpillars are very different from their adult counterpart. It's not always that way. Larvae of insects can look a lot like their adult form
• StudentWhat type of caterpillar is this?
  Bugscope Teamnot sure. it was kind of smooth, so definitely not a wooly bear caterpillar
• Bugscope Teamcaterpillars dont have a proboscis like a butterfly or moth, they have jaws
• Studentwhat are crochettes
  Bugscope Teamthey use those hooks attached to ther legs to help stabilize themselves while they are on plants
• Studentwhat are the bony things
  Bugscope Teamthose are the hooks that help the caterpillar to hold onto things, like leaves and plants
• StudentWe rased caterpillers in the fall
• Studentare these bones
• Studentcan we see spericles
  Bugscope Teami tried finding a spiracle this morning, but i couldn't find one, sorry. maybe we'll run into one later. spiracles are very cool, that is how insects breathe
• Bugscope Teamalthough these look like bones, they are not bones at all. insects don't have bones
• StudentWow
• Studentcan we see another body parts?
• Bugscope Teamsome insects have special pads of hair by their legs that help them stick onto vertical surfaces, these might help acheive the same purpose
• Studentcan we see a simple eyes on a caterpiller

• Bugscope Teamokay, now we are moving to a beetle. this is a compound eye on a bettle
• StudentWhats a proleg?
  Bugscope Teamcaterpillars have segments of legs that come in pairs, they are called prolegs
• Bugscope Teamsure, we'll get to the simple eyes in a second
• StudentCool!!!
• Studentthankes for swiching alex
• Studentwhat are those thorn things.
• Studentwhat are the spikes
  Bugscope Teamthose are insect hairs that we call setae (see-tee). They help the insect know what's going on around it in its environment
• 7:48 am
• Studentcan we get closer
• Studentcan we get any closer
• Bugscope Teamthose spikes or hairs are called setae (pronounced see-tee)
• StudentCOOL!

• StudentThis scary!!!!
• Bugscope Teamnow we are at 1268x magnification
• StudentCOOL!!!!!!
• Bugscope Teamthis is its compound eye
• Studentdoes it have hair?

• Studentwhat are those bumps
  Bugscope Teamthose are the individual facets, lens, of a compound eye

• Studentlook at the bubbles

• StudentCAN WE GO CLOSER?
• Studentwhat is this ?

• Bugscope Teamthose spikes are setae, those are very important to insects
• StudentGO CLOSER MUCH CLOSER PLEASE
• StudentHow close is this?
• Studentcooooooooooooooooooooooooooooool!
• Bugscope Teamthis insect has a bit of juju on it. Some liquid must have gotten on it and dried
• StudentIs this a bettle?
• Bugscope Teamsince insects have a hard outer shell, an exoskeleton, and that shell can't feel anything, they need some way to feel things. that's where the setae come in
• Studentwhat is juju
• Bugscope Teamthe setae stick through the exoskeleton, attach to nerves underneath
• StudentCOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL ITS HAIRY
  Bugscope Teamyes insects are a lot hairier then they eem
• Bugscope Teamyes, this is a beetle
• StudentI can see dirt
  Bugscope Teamyep, dirt and grime, we call it juju

• Bugscope Teamseem
• StudentWhat is that dirt stuff?
  Bugscope Teamit's just dirt
• StudentWhat are the bumps on the eye
  Bugscope Teamthose are the individual components of the compound eye. think of them as a different lens. we call each part of their eye an ommatidium
• StudentIS THERE A LITTLE BUGS ON THE HAIR
  Bugscope Teami'm going to go find out
• Studenthow do bugs have all these detailed gross parts
• Bugscope Teamwell move to the bumps on the eye in a sec

• Teachercan you choose another for us?

• Bugscope Teamflying insects have tons of ommatidium
• Bugscope Teamsure, i'm going to focus on the little piece of dirt that alyssa wanted to see

• Studentgot any info
• Studentare there bugs on there hair
• Bugscope Teamhey alyssa and jacod, this is that piece of dirt, it looks like dirt, not a bug, sorry
• Studentcloser

• StudentDoes juju appear often?

• Studentcloser

• 7:53 am
• Bugscope Teamthis is 20,000x magnification!!!
• Studentthat looks like a sword
• StudentWhat is that?
• Bugscope Teamthis scope can go up to 600,000x mag, but for these bugs, we don't go much past 40,000x
• StudentGo out so i can see the eye
• Bugscope Teamthat sword looking thing is a sensory setae, they help it to sense things in the world

• Studentplease!!!

• Bugscope Teamokay, now we are back to the compound eye
• Studentthank you
• StudentCAN YOU GO NEXT
• Bugscope Teameach bump in the eye is called an ommatidium, as cate said
• Studentthis is HUGE!!!!!!!!!!!!!!!!
• Bugscope Teameach ommatidia has a lens in it
• Studentcan we see the grasshper head
• Bugscope Teamyeah, insects have very cool compound eyes
• StudentCan we see the but?
• Studentwhat is an ommatidium
  Bugscope Teamthey are individual lenses of the eye
• Bugscope Teamthe difference here though, is that the insect compound eye can't move the lens like humans can
• Studentcan we see something else?
• Bugscope Teamflies, wasps, and bees have really big compound eyes that make it impossible ot count all the ommatidia
• Bugscope Teameach lens is fixed, but since there are hundreds of lenses, they can see a wide angle
• Studentcan we see the grasshoper head
• Studentmay we see the thrax
• Studentcan we see the thorax
• Bugscope Teamokay, we are moving to the grasshopper head now

• StudentWe meen butt
• Bugscope Teamyeah, insects have a butt area, but it's called an abdomen... :)
• StudentCLOSER
• Bugscope Teamcheck out the compound eye on the left, and the antenna above it
• Bugscope Teamto the right are the mouht parts, with some palps
• Studentcloser, please
• StudentAre those teeth?
• Studentare those hairs on their head
• Studentcan we see it :)
• 7:58 am
• StudentLOSER
• StudentCOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL ?
• StudentCLOSER
• Studentwhat are we looking at
• Studentwhat is this
• Studentit looks like the moon
• Bugscope Teamsetae help insects to sense things
• Studentwhat are we looking at
• StudentSORRY I MENT CLOSER
• Bugscope Teamsetae can be mechanosensory, sensing movement. or they can be chemosensory, and sense smells and tasts
• StudentWhat is this?
• Bugscope Teamsetae are VERY important to insects
• Bugscope Teamthis is the grasshopper
• StudentCOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL!!!!!!!!!!!!!
• Bugscope Teamthis is now the antenna
• Studentsweet
• Bugscope Teamthis is a shaft on the antenna
• StudentIs this the leg ?
• StudenttHIS SCARY
• Studentit looks like a tree
• StudentCLOSER CLOSER CLOSER!
• StudentAre there sete on the antena?
• Studentwhat are the differences between a grasshopper and a cricket?
• Bugscope Teamwe think these are brochosomes!!!!
• StudentWhat is that , it look like snake skin
• Studenthowbig is this
  Bugscope Teamwell, if you look at the scale bar in the lower left, you'll see a ruler
• Studentwhat is a brochosome?
  Bugscope Teama brochosome is a tiny waxy particle like an open soccer ball that is produced by leafhoppers but ends up often on other insects
• Studentit looks like an eye
• StudentIs it a baby?
• Bugscope Teamthis antenna part is probably chemosensory, in that is can sense smells (ie, chmicals)
• Studentis that a egg
• StudentWhat is scott doing
  Bugscope Teamscott is controlling the scope now, finding some interesting things to look at for you guys!
• Studentcan we see the mandibles?
• Studentwhos your partner or do you not have one
• Bugscope Teambrochosomes may be used to help keep eggs from drying out, but we are not sure of their purpose
• StudentTHIS IS HUGE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Studentwhat is that black thing
• Bugscope Teama um (in the scale bar) is a micron. one micron = one millionth of a meter
• Studentcan we see the flea head?
• StudentCan we see the head again

• Bugscope Teambrochosomes were first discovered in 1952, when someone put a leafhopper in an electron microscope, much like what you are looking at noe
• Studentcan we see the flea head
• Bugscope Teamthis is the head of the flea
• 8:03 am
• Student:) :)
• Bugscope Teamthis is a flea
• Studentit looks like a dinsor
• Studentis this a flea head?
• Bugscope Teamfleas also have compound eyes
• Bugscope Teamyes, this is a flea head
• Studentwhat is the teeth things
  Bugscope Teamthat is part of the cuticle on the face; we are not sure
• Bugscope Teamthe eyespot is to the right, and the mouthparts are to the left; it is facing north
• StudentWHOA
• Studentare those teth cause they look scary
• Studentit's scary
• StudentEyes
• Studenti ment teeth
• StudentNOW I THINK THAT FLEAS ARE ALL OVER ME
• Bugscope Teamheh, well, fleas are a part of life...
• StudentIt looks wierd.
• Studentwhat are those circles in back
  Bugscope Teamthose are holes in the stick tape that we put the bugs on
• StudentMy dog and Jafars cat hates them.
• Studenthow is this possible?
  Bugscope Teamhow is what part possible?
• Studentwe know, but still
• Studenti hope i dont have a flea on me cuse they eat your head
• Studentcool
• Bugscope Teamthis is one of the biting parts of the flea
• StudentIs this an eye?
• Studentwhat is that
• Studentscary
• Bugscope Teamthis is part of the flea that cuts into your skin
• Studentgross
• Studentwhat is the leafy stuff
• Bugscope Teamsee how it looks like a chainsaw blade, in a way?
• Studentit looks like a sting ray.
  Bugscope Teamyes!
• Studentcan we see the mouth?
  Bugscope Teami don't think we can see the mouth from this angle
• Studentwhich part does the flea suck blood with?
  Bugscope Teamthe part we saw -- one of the laciniae -- cuts into your skin. there must also be a siphon tube of sorts but we did not see it here
• Studentit looks like coral
• Studentwhere is its eye
• StudentBack there
• StudentOk :)
• 8:08 am
• Studentcan we see a nother bug
• Studentisiy looks like a crab leg
• StudentIt looks lik a crab
• Bugscope Teamsee the large powerful legs
• Studentis that a flea
  Bugscope Teamyep, that was a flea

• Studentwow

• StudentWhats that?
• Bugscope Teamthese are palps on a beetle
• Studentwhat is that
• Bugscope Teampalps help taste and smell food that the beetle eats
• Studentwhat are palps
• Studentwhat is a p
• Bugscope Teampalps can also shovel food into the mouth if need be
• Studentare they on the feet
• Studentare those the legs
• Bugscope Teampalps are little sensory things that are around the mouth, they help taste food
• Studentwhere is the palp
• Studentare we on we on the feet
• Studentoit looks like a a hand
• Studentno o
• Studentchange it its scaring us
• Bugscope Teamyes! you can see some claws now, scott is going to focus on them
• Studentcan we see a closer view of th mouth
• Bugscope TeamBOOOOO!!!!!!!!!!! (ha ha)
• Studentthank you
• Studentits time for us to go now thank you
• Bugscope Teamthis is a beetle claw
• StudentThanks!!!!!!!!!!!!!!!!
• Bugscope Teamyou all did great!!!
• Studentthaks
• Studentbye bye
• StudentthaaaaNKS!!!!!!!!!!!!!!!!!!!!!!!!!!
• Studentbye
• Studentthis was cool
• Bugscope TeamThanks!
• Studentthanks have a grate day
• Bugscope Teamyou all did really well, you are budding little scientists
• 8:14 am
• Bugscope Teammrs vignale, how are things going on your end, from here it seems like the kids are happy and learning
• Bugscope Teamalso, we are going to have to end the session right at 10AM (your time), as the scope is needed at that point by a researcher
• Bugscope Teamhowever, keep in mind, all the chat and images are saved to your member page: http://bugscope.beckman.illinois.edu/members/2009-091, you can review the session anytime with your students
• Bugscope Teamyeah
• 8:21 am

• StudentHi the next group is logging in now and the last group left here totally jazzed!
• Bugscope Teamwelcome to bugcope!
• StudentHi!
• Studenthave u ever seen a cool dude bug?
  Bugscope Teamhere's one!
• Studenthow'd you get these
  Bugscope Teamusually the school will send us insects to put in the scope, but we have a collection as well

• StudentHi
• Studentcool!
• StudentHI!
• Studentwhat are we looking at
• Studentwhat is this
• Bugscope Teamthis is a fruit fly
• Studentheuoooooooooooooooooo
• Bugscope Teamsee its eyes?
• Studentwhat are we looking at ?

• Studentwhat is this
• Bugscope Teamthis is a fruit fly head
• Studentwhat is this bug
• Bugscope Teamthe little things that look like blinders are the antennae
• Studentcan you zoom in
• Bugscope Teamyou can see it's huge compound eyes, and the stubby antenna on top
• Bugscope Teamokay, we are zooming in on the compound eye now
• Studentare those scales?
• Bugscope Teamthose bumps are the individual facets of the eye
• Bugscope Teameach bump has a lens in it
• Bugscope Teamyou can see the individual ommatidia -- the facets of the eye
• Bugscope Teamand you can see bristles in between most of them
• Studentwhat are the spikes
• Studentwhat are the spikes for
  Bugscope Teamit is thought that those spikes help sense wind speed when flying, that helps the fruit fly to fly around better
• Studentzoom in closer
• StudentThat cool
• Bugscope Teamso, the fruit fly can see thousands of images with this compound eye, and the fly brain assembles all those images into one simple image for the little buggar
• Bugscope Teamthose bristles, or setae -- spikes -- help the fly gauge the speed of the wind and its direction
• StudentWhy is it called a Fruit Fly?
  Bugscope Teamwell, it likes to feed on decaying mold that grows on fruit
• 8:26 am
• Studenthow close can u go?
• Studenthow did you get it this close?
• Studentare the brisels sharp
• Studentwhat are the bumps for?
  Bugscope Teamthe bumps are the facets of the eye -- individual lenses
• Studentcool
• Studentdo u no what his skin's made of?
  Bugscope Teamwell, it's not skin, it's called an exoskeleton and it's made of chitin, like what your fingernails are made of
• Studenthow far can you zoom in
• Bugscope Teamthe fruit fly pukes on its food, and then sucks up that puke - it's a really royal lifeform!
• StudentWo that ieg looks cool
• StudentWhat is that?
• StudentThats cool
• Studentwhat's this
• Studentintresting
• Studentit looks like a inside of a pumpkin
• StudentWhat is that cool looking bug
• Studentare these legs?
• Bugscope Teamah cool, here's a claw
• StudentLegs?
• StudentIt looks spikey
• StudentCool!
• Studentwhere did u find this bug?
• Bugscope Teamyeah, those spikes are the hairs (setae) again
• Studentits like a crab
• Bugscope Teamthe setae re vital to all insects
• StudentClaw?cool!
• Studentis it spiky
• Studentwhy do fruit flies have claws?
• StudentWhy are there claws?
  Bugscope Teamwell, insects need to grab onto things for survival, so most have claws of some sort
• Bugscope Teamsetae help insects to feel their environment. setae can sense movement, tastes, smells, temps, etc.
• Studentzoom in as close as you can
• Bugscope Teamclaws are sort of like hands to us
• Studentthis claw loks lik a handcuff!
• StudentWo cool
• Studentthat is awesome!
• StudentWOW!
• Bugscope Teamthere's a brochosome, on the left
• Studentdo they have 6 claws?
• Studenthow far can you zoom in
  Bugscope Teamwe can go farther, but soon it will not be so interesting
• Bugscope Teambrochosomes are made by the leafhoppers
• Bugscope Teamthe scope can magnify 600,000x, but for these insects we don't go much past 40,000x
• Studentwhat are leafhoppers?
• Bugscope Teamnotice the scale bar in the lower left: click on it
• StudentWhat are those round things
  Bugscope Teamthose were the brochosomes
• Studentwhat part of the bug is this?
• Studentwhat is that?
• 8:31 am
• Studentwhat are leafhoppers
• Studentwhat is that circle in the back round?
• Bugscope Teamleafhoppers are plant pests
• StudentCan we move to another sample...maybe the caterpillar
• Bugscope Teamnow we are going to another fruit fly
• Studentwhat is it?
• Studentlook at the intenas
• Studentoh
• Studentis that a bug?
• Bugscope Teamah, we'll get to the caterpillar in a sec mrs vignale
• Student-can we c a clos up on the i?
• Bugscope Teamthis is a spiracle!!!!
• Bugscope Teamthis is how insects breathe
• StudentWOW!
• StudentAWESOME1
• Bugscope Teamnotice all the setae surrounding the spiracle, that's so dirt and juju doesn't fall into it
• Studentis that a hairy eye?
  Bugscope Teamno, that was a spiracle, a breathing hole
• StudentWhy is it so hairy?
• Studentcool!!!!!
• Bugscope Teamthose hairs are vital, they help it to feel things
• StudentIt is fuzzy
• Studentwhy isn't it in color
  Bugscope TeamIts because we use electrons, which are much smaller than the wavelength of light
• Student is that all hair
• Studentfuzzy
• StudentWhat are those
• Studentawsome!
• Studentis that its skin?
• StudentIs that its face
• Studentcan you put it i colar
• Studentwhat is that?
• Bugscope Teaminsects have a hard outer shell, called an exoskeleton, and that exoskeleton can't feel anything. the hairs (setae) stick through the exoskeleton, to nerves underneath, and that's how they feel things
• Bugscope Teamthis is an antenna, a close up
• StudentWhat are those
• Bugscope Teamthis is the antenna, up close
• Studentwhy is it black and white
  Bugscope Teamgood question. this is an electron microscope. so we are using electrons to get the image, we are NOT using light. color is a property of the frequency of light, and since we are not using light, there is no color. but what we don't see in color, we make up for with amazing contrast and magnification
• Studentwhat is this?
• StudentWhat is that
• Studentis that sharp
• Bugscope Teamthis is what the fruit uses to help it smell where fruit is
• StudentWhat are the bumps for?
• Studentwhat is it?
• Studentis that a part of the antena
• Bugscope Teamthe setae and other projections are mostly chemosensory -- for sensing chemicals in the air
• Studentwhy are there so many?
• Studentis it possible to put it in color
  Bugscope Teamyes, after the images are collected, one can do an elemental analysis of the image and color in based on that data. but we don't do that for bugscope
• Studentcan we c a diff bug?
• StudentWHAT IS IT!?
• 8:36 am
• Studentwhat is that
• Studentwhat are those little spots?
  Bugscope Teamthose are bumps in the tape we put the bugs on
• Bugscope Teamwe think this is a stonefly
• StudentThats a bug right
• Studentwat is this?
• Student?
• Bugscope Teamthis is a stonefly larva
• Studentcan we see a different bug?
• Studentwhat is a stone fly?
• Studenta stonefly?
• Bugscope Teama stonefly is an aquatic bug
• Studentcan we c a cenapeed?
• Bugscope Teamwe are going to the caterpillar now
• StudentWhat is it laying on
• Bugscope Teamwait, quick stop at the mayfly, another aquatic bug
• Studentcool!!!
• Bugscope Teammayfly's and stonefly's both live in the water and feed on decaying plant matter
• Studentwhat does aqactic bug
• StudentWhat is that
• Bugscope Teamit means it lives in/around the water
• Studentcan we c the i's
• Studentan it swim?
• Studentwhat is that
• Bugscope Teamthis is the eye of the armored mayfly larva
• Studentit looks like durt
• Studentwhat is that
• Student.
• Bugscope Teamyeah, lots of juju on this eye
• StudentWhat are those spikes
• Bugscope Teamthis is some kind of crystal on the eye... cool!
• Studentis that the i
• StudentIS that scum
• Bugscope Teamthat spiky thing is the crystal
• StudentwHAT IS IT?!
• Studentis that an a eye
• Bugscope Teamthe crystal must have bloomed on the eye while we kept the sample here
• Studenttell us more about the crystal
• Studenttell us about the crystal
• Bugscope Teamthis is an antenna
• Studenthow do they see with all that juju?
  Bugscope Teamthe juju was not all there when the mayfly was in the water
• Studentwow
• Studentis that an antena?
• Studenttell us more about the crystal
• Studentwhat is this
• Bugscope Teamyep, this is an antenna
• StudentWhat are those spikey things
  Bugscope Teammore setae, used to sense things
• Studentwhy are there holes
  Bugscope Teamwell, there are actually little setae sticking out of those holes
• Studenthow is juju pronounced
  Bugscope Teamit is pronounced, jew-jew
• 8:42 am
• Studentcan we c a centapeed
  Bugscope Teamwe don't have a centipede today, sorry
• Studentwhat is juju?
  Bugscope Teamthat's our name for dirt or grime, or stuff we don't know what it is
• StudentWhat is it?I mean the holes.
• Student!!!!!!!!!!!!!!!!!!
• Studentwhat is this
• Studentwhat is that
• Bugscope Teamif you image is black or delayed, try refreshing. (F5)
• Studentwhat is that stuff
• Studentthat is hairy!!!!!!!!!!!!!!!!
  Bugscope Teamyes, or rather, setae-y
• Bugscope Teamthese are mouth parts of a mayfly...
• Studentwat is t spiky stuf?
  Bugscope Teama lot of it is setae that help filter the water
• Studentwoah
• StudentWhat are we looking at?
  Bugscope Teamthis is the mouth of the armored mayfly nymph
• Bugscope Teamthe spikes are setae, used to feel things, taste things
• Bugscope Teamthis is a mouth of a mayfly
• StudentWhat is it
• Studenthow do you get so close?
  Bugscope Teamthis is an electron microscope, it uses electrons to get the image, so it can magnify very very small
• Studentw hat part of the caterpiller are we looking -at

• Studentcan we move on
  Bugscope Teamyes!
• Studentnice zoom out!
• Studentwat is this part"?
• Bugscope Teamnow we are going to the caterpillar
• Studentthats cool
• Bugscope Teamthis is the head of the caterpillar
• Studentwhat are those bumpy things on the head
  Bugscope Teamthose are the eyes, called stemmata
• Studentyeah
• Studentwhat is that!!!!!!!!
• Studentwhat is that+
• Studentis this the catapiler
  Bugscope Teamyes it is the caterpillar
• Studentzoom in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Bugscope Teamsimple eyes
• Studentwow
• Studentcan we lok at the mouth
• Studentzoom
• Studentthat looks wierd
• Studentis that a leaf
  Bugscope Teamit is a scale from another insect -- a butterffly or moth
• StudentIts bumpy
• Studentwhats this
• StudentWhat is this?
• Studentwat is the lef thi';[n
• 8:47 am
• Studentwhy is that leef shaped thing on it
  Bugscope Teamit just stuck on there at some point -- it is a scale from a butterfly or moth -- the powdery soft stuff you feel when you rub one of the wings
• Bugscope Teamthe little oval things are bacteria
• Studentis the bacteria bad
  Bugscope Teambacteria will eventually get on everything and cause things to decompose, so they are not really bad all of the time
• Studentwhy is bacteria on it?
• Studenthow did u find thes?
• Bugscope Teamwell, bacteria grows on everything eventually
• Studentwhy is there bactiera on the caterpillar
• StudentWere do you find all these bugs
• Studentis that the mouth
• Bugscope Teamthese are spinnerets
• Studentis that an eye
• Studentis that bump of the catapiler or did he get it from geting hurt?
  Bugscope Teamhe got hurt
• Bugscope Teammany caterpillars can make silk, like spiders can
• Studentow
• Studentwat els bugs mak silk?
• Studentis there a way to keep bactiera from growing
  Bugscope Teamwell, there are, soup and water can do wonders
• 8:52 am
• Studentis that his mouth?
• Studentwhat is that hole or is it a hole?
  Bugscope Teamthat is the entrance to the mouth
• Studentwhen we studied caterpillars I never was that close
• Bugscope Teamthat's why it's good to wash your dirty hands, it will reduce bacteria
• Studentmay we see the prolegs
  Bugscope Teamsure!
• Studentcloser into the i,please
• Studentcan you go inside
• StudentWHat are those bups
• Studentwhat is that?
• Studentr thos th eegg
• Studentwe studied catapilers
• Bugscope Teamthis is a scale
• StudentWhats that?
• StudentProlegs are cool
• Studentwhat are the hears for?
  Bugscope Teamthe hairs are called setae, they help it feel things
• Studentwhy is it all shriveled up?
  Bugscope Teamwhen insects die they dry out and that can cause them to shrivel up
• StudentOMG
• Studentlook at those claws
• Studentare we inside it?
• Studentcan we go inside
• Studentwat r the loopy thi
• Studentis that a claw?
  Bugscope Teamit is a claw, or a bunch of them, on the caterpillar proleg
• Bugscope Teamthese are called crochets
• StudentOMG!
• Studentr croches sharp
  Bugscope Teamyes, they are
• Bugscope Teamin addition to the six legs they already have, caterpillars often have a number of extra legs called prolegs
• Bugscope Teambut they are very small too
• Studentwhy are they so thin arent they suppposed to be thick so they can grab better
• Studentmay we see the grasshopper head?
• Bugscope Teamprolegs usually come in pairs too
• Studentcool can we see a different part of the body
• Bugscope Teamwe are moving to the grasshopper head now

• Studentcan they hurt humans?
  Bugscope Teamno, not really
• Studentdid he get hurt
  Bugscope Teamhe lost one of his antennae but that may have been after he died
• Studentwhat is the bump?
