- Bugscope TeamGood Morning!
- TeacherHi Scott and others at Bugscope
- Bugscope TeamWe are (you can see) setting up. A few more presets and we'll have it.
- Bugscope TeamCate is on the Console, running the 'scope.
- Bugscope TeamAnnie should be on soon.
- TeacherI am setting up student computers. Students are not here yet. Take your time- this is very interesting too.
- 10:40 am
- Bugscope TeamAnnie!
- Bugscope TeamHello all
- Bugscope Teamhi Annie
- Bugscope TeamHi Alina
- Bugscope TeamOops I just 'found' the pollen grain Cate had already made into a preset.
- 10:46 am
- Bugscope Teamhello! welcome to bugscope
- TeacherHi Bugscopoe! Our 2 classes of students are here now.
- Bugscope TeamHi!
- TeacherHi cate2
- TeacherHi Scott
- Studentwhat kind of bug is this
- StudentHi! What kind of bug is this?
Bugscope Teamwe are on the cicada head. This is a pollen grain on it
- 10:51 am
- Bugscope TeamThis is the head of a cicada, up so close we can't really tell where we are.
- Studenthey guys!
- Bugscope Teamso what we see now is pollen
- StudentCool!
- Studentwhere did you find it?
- StudentWhere did it come from?
- Studentwhat is this?
- Studentsparkale do you like this pic?
- Bugscope Teamthis is a cicada that came from Annie's collection.
- Studentwhat part of the bug is it.
- Bugscope TeamAnnie collected the cicada, as for the pollen grain, it could be ragweed or something similar
- StudentWhat is it
- StudentAWESOME!
- StudentWhat is this part?
- Studentscott where did she get it?
Bugscope TeamShe collected it from around here, from Illinois, I think.
- Bugscope Teamthe cicada was so big we could only put the head on the sample stage
- Studentwhat is this psrt?
Bugscope Teamare are on the timpanum of the cicada. It is found on the head. You can see there are a lot of hairs inbetween the ridges
- Studentscot do you like this project?
Bugscope TeamYeah this is so much fun for us.
- Bugscope TeamScott is this the cicada with the orange wing?
Bugscope TeamThe Otaku might know -- she and Alina made this sample.
- StudentInteresting
- Studentwhy did you chose this bug
- StudentThisis really cool!
- Studentwhat type of bug is it?
- Studentwhat is this
- StudentIs that hair?
Bugscope Teamyes, but on insects we are supposed to call them setae. Insects are a lot hairier then they seem!
- StudentOrange wing?
- Studentwat bug is this?
- StudentWhat color is it really suppose to be?
- Bugscope TeamActually, this is called the cibarium..it is on the head. The cicada compresses it and contracts it like a bulb to suck plant juices
- Studenti love this i think its cool but nasty
- Studentwhat is that part?
- Bugscope TeamThis is a periodical cicada that I collected in Kentucky in 2003
- Studentwhat are those tubes
- Studentwhat are those tubes
- Studentis that the eye?
Bugscope Teamthat is the compound eye
- StudentWhoa
- Bugscope Teammy fault for the misidentification of the cibarium, which makes the cicada look like a Klingon
- Bugscope TeamCan this eye see like a human eye?
Bugscope Teamit can see sort of like a human eye -- the brain has to assemble all of the images into a single image
- 10:56 am
- Studentnew words in my vocabulary
- Studentwhat kind of bug is it?
- Bugscope TeamMost insects that suck plant juices have a cibarium
- StudentI know I can't wait to tell my parents!
- Bugscope Teamtrue bugs have them, they just usually arent so big
- StudentIt looks so big even thow it is small
- Studentwow i didnt know what an insect's eye looked like this!
- StudentNOW WHAT IS THAT
- StudentHI
- Bugscope Teamthe eye is really streamlined-- plain looking
- Bugscope TeamSo Annie, how to do you collect these insects?
Bugscope TeamThis was one of the cicadas from the big huge cicada emergences. It was impossible NOT to collect this cicadas. The were everywhere!
- Studenthello
- StudentHow can you tell if its boy or girl
Bugscope TeamWe are not going to be able to tell if it is a boy or a girl from here. The females have a big long ovipositor and are fatter. But, we only have the head on the stub today
- Studenthi jo
- Studentim not sure
- Bugscope Teamgood job :)
- StudentHOW DO YOU FIND THE INSECTS?
Bugscope TeamThere was a huge mass emergence of cicadas in Kentucky in 2003 and they were EVERYWHERE, in big huge piles on the sidewalk and at the bottom of trees.
- Studenthi
- Teacherwe want to see the compound eye structure
Bugscope TeamWith the cicada it is hard to see the ommatidia very clearly.
Bugscope Teamit isn't very easy to see on this cicada. We could try on a different insect though
- StudentHELLO?
Bugscope TeamHi Spike!
- 11:01 am
- Studentwhat are those bumps on the eye
Bugscope Teamthose look like pieces of dirt or something similar
- StudentHow big is the eye
- StudentHOW do you tell the gender?
Bugscope TeamThe female cicadas have a long pointy ovipositor on the abdomen
- Bugscope TeamYou will notice that we don't always get to answer all questions 'cause they go by so fast.
- Studentwhat are those bumps?
- StudentWhat kind of incect do you think this is ?
Bugscope TeamPanthers this is a cicada.
- Studenti do not know
- Studentdo we have this dirt on ower eye?
Bugscope TeamNo we don't because we have eyelids as well as moisture that can help fend off dirt and other particles. Insects can't close their eyes and they can only really clean them with their legs\
- Studentis this still the eye?
Bugscope TeamGuy we have left the eye and are a little lost right now, looks like.
- Bugscope Teamif you get lost take the mag down lower to see where you are, or you can click on a preset
- Studentis that still the eye
- StudentHow close dose the scope go
- Teacherok- whose going to drive now?
- Studenthow close is the eye
- Studentwere are we
- Studentok
- Bugscope TeamWould you like us to give control to one of your students?
- Bugscope TeamClick on a preset to get back in action
- Teacherwe want you to drive for now
- Studentwhats that?
- Bugscope Teamthis is on a dog tick, this is a claw
- Studentwhat is this
- Bugscope TeamTicks are actually related to spiders; they're not insects.
- Studentwhats that?
- Studentwhat is a dog tick
Bugscope TeamIt is a very common large tick. It's genus and species is Dermacentor varabilis
- Bugscope Team ticks suck blood, right?
Bugscope Teampart of their head, called the capitulum, sticks into your skin
- Bugscope TeamTicks, when they are young, may have six legs, but when they get older they have eight.
- Studentwhat is this?
- Studenti think so
- 11:07 am
- Studentwhat part of a tick is that?
- Studentwhat do ticks eat
Bugscope Teamthey drink blood from mammals
- Studentcan you show us its head?
- Studenthow big is this
Bugscope TeamSmaller than a pencil eraser
- Studentcan you show us the head
- Studentcan you show us the head?
Bugscope TeamWe're driving over to it now
- Studenthi
- Studentis that the head
Bugscope Teamthis is the head- more specifically its mouthparts
- Studentis that the leg
- Studenthow doses a tick suck blood?
- Studentwhat is this
- Studentis it tiny in real life
Bugscope Teamyes it is very small -- from a few mm to several mm across, until it gets full
- Studentwhat body part is this
- Studentthat looks asome
- Studenthow long is a tick
- Studentewwwwwww.........
- Studentwhat are the things on its head
- Studentcan they suck blood from people?
Bugscope Teamyes and they can transfer diseases to us like lyme disease
- Bugscope Teamthis is the head, and it is kind of yucked up today
- Studentcan you zoom in more?
- Studentwhat are the spikes on its head?
Bugscope Teamthe v-shaped things in the middle are what hold it into your skin
- Studentdo they have hair
Bugscope Teamyes the small spikes you see are hairs
- Studentcan we see the eye
Bugscope Teamthey don't reallty have eyes -- they have eyespots that are on the other side of the head where we can't se them
- Studentcan we see the eye
- Studentcan we see the eye
- Studentwhat are the things on its head for
- Studenthow many x is this
Bugscope Teamwe are at 510x magnification right now
- Studentzoom in please
- Studentcan we see the eye
- Studenthow big is a ticks head
Bugscope TeamVery small about 3-5 mm across
- Studenthow do they taste things?
Bugscope TeamLike all arthropods they taste with setae that detect chemicals
- Studentis that the eye
- Studentfrend
- Studentwhat are those bumps?
Bugscope TeamThese are little setae that help the tick to "taste" its host
- 11:12 am
- Bugscope Teamthis is one of the palps, on the side portions of the head
- Studentwhat is this on the eye
- Studentif it is the eye
- Studentwhy don't they have eyes
Bugscope Teamthey don't need them - they use their sense of smell and the ability to sense heat and perhaps CO2 -- your breath -- to find you
- Studenthi
- Bugscope Teamhod do they know where they're going without eyes?
- Studentwhat are those pointy things
- Studentwhit is this?
- Studentscot what is that
Bugscope Teamthat is one of the palps on the side of the head that let the tick smell things
- Studentwhat are those pointy things?
Bugscope Teamthese are special setae (which are insect hairs) that allow the tick to smell/taste things
- Studentwhat are those things sticking out of thier head
- Studentwhat are those
- Studentwhere do ticks live
Bugscope TeamTicks live in forested and grassy areas all over.
- Studenthow do you remove a tick
Bugscope TeamI have been taught that you should grip the tick as close to the base of its head as possible and firmly pull it out with tweezers. You want to avoid any of the head breaking off in your skin because it can cause an infection
- Studentwhat is that
- Studentwhat is that
- Bugscope Teamhere is a better view of a compound eye, this time on a fruit fly
- Teacherstudent asks, where do ticks mostly aim for?
Bugscope TeamThey don't discriminate...they will grab on whereever they can. I usually find them on my shoes or socks
- Studentwhat is that\
- Studentwhat is that?
- Studentwhats that?
- Studenthow do ticks jump so high
Bugscope Teamticks climb to high places and put their arms out so when you pass by they can cling on
- Studentwhat is that white sticking out
Bugscope Teamthe white things are setae or bristles that stick out of the compound eye of the fruit fly
- StudentIs that its body part
- Bugscope Teamticks will climb up long grass and cling to them with their hind legs in the air to grab onto your clothing or animal's fur
- Studenthow to ticks live?
Bugscope Teamthey have a kind of complicated lifecycle; they often go through a couple of molts before they finally lay eggs and start the cycle over again
- StudentI dont know.....
- 11:17 am
- Studentdo ticks walk fast
Bugscope TeamNope, they creep very slowly
- Studentdoes it hurt
Bugscope TeamTicks don't hurt at all when they bite you. They bank on you not being able to feel them. A tick bite can be very itchy, especially if you pull a feeding tick out. TIck bites can also get infected
- Studenthow does a tick get on you/
Bugscope Teamticks have little hooks where you would think their underarm would be, and they can fit those over leaves so that when you go by they can use their arms to cling onto you
- Studentdo ticks live on blood?
Bugscope TeamYes they do
- Studentis that dirt?
- StudentYes......
- Studentwhat are those gray balls in the middle
Bugscope Teamnot sure what those are. we usually call them juju when we know they are matter that don't belong, like dirt or dust
- Studentdo ticks live on blood?
- Bugscope Teamwhat's that little blab in the center?
- Studentdo they stick to humans
- Studentwho many live on it's eye?
- Studentdo they just suck blood?
Bugscope TeamYup that is all they eat
- Studentthats the compound eye right
Bugscope Teamthat was the fruit fly's compound eye
- Studenthow far can the jump
- Teachercan we see praying mantis part?
- Bugscope TeamGood idea!
- Bugscope Teamthis is the small praying mantis
- Bugscope Teamhere is our smaller praying mantis
- Studentwhat are those hairs?
- Studentwhat do those little hairs do
- Studenthow long will this prayinmantis live
Bugscope TeamIt will hatch from its egg in the spring, about this time of year and it will die in the fall when it frosts.
- Bugscope Teamsee the mouthparts? they are pretty complicated
- Studentcan tou go closer?
Bugscope Teamsure!
- Bugscope Teamand see its compound eyes?
- 11:22 am
- Studenthow big can they get
Bugscope TeamA large female Chinese mantis can get about 5 inches long. Pretty big. Carolina mantises are smaller, about 3-4 inches maximum
- Studentwhat do they use those things that look like anemones for?
- Studentwhy does its head look so puld apart
Bugscope Teamthe mouth, especially, is just strange-looking -- it looks like it's laced together
- Studentcn you go closer to the eye?
- Studentcan you zoom in?
- StudentWOW!!!!!!!!!!!!
- StudentCOOL
- Studentwhat is the white stuff?
- StudentWhy is the eye so dirty
- StudentIm back
- Bugscope Teamwhat are those spots?
- StudentWhat part is this of the praying mantis?
Bugscope TeamPork Chop this is the eye, up close.
- Studentis that dirt
- Studentcool!
- StudentCan it hear
- Studentnow what are those spunge things
- Studentis this the eye?
Bugscope Teamyes we are on the eye right now
- TeacherHow about beetle head?
- Bugscope Teamthis is the eye -- we don't know what the stuff is on it, though
- Studentcan you zoom out some?
- 11:27 am
- Studentcan it hear
- Studentare those spoug thing duart
- Studentis this a betl?
- Studentwhat animal is this?
- Studentwhat are those hairs for?
Bugscope Teamthe setae help the beetle to sense its environment
- StudentCAN IT HEAR
Bugscope TeamThey can sense vibrations with specialized hairs all over its body. I am not sure if any beetles are know to have "ears" or specialized ear-like organs.
- Studentis this a betle head?
- Studentcan it smell?
Bugscope Teamyou can see the small parts sticking up, that is a palp and it has special hairs that allow it to taste/smell
- Studentwhat are the dots on the thing?
- Bugscope Teamthis beetle is a tad bit dirty as well
- Studentwhat kind of bettle is this?
- Bugscope Teamthis is copied from a paper about the mantis ear: Most praying mantids have a single ear located in the ventral midline of the metathorax. It comprises an auditory chamber, two tympana, and four sensory organs. Mantids have sensitive hearing for frequencies >20 kHz.
- Studentwere did you find it
- Studentcan it make noses?
Bugscope TeamMany beetles do make noises...they squeak or hiss if the are harassed
- Teachercan we zoom into mouth?
- Studentcan we see the eye
- Studentwhat are those dots
- Studentcan it hear?
- Bugscope Teamwe can't see them right now though
- Bugscope Teamyuck we can see what it was eating
- Studentcan it smell?
Bugscope TeamIt smells with specialized setae that are concentration on the antennae and mouth, but that may be located elsewhere
- Studentwhat are those hairs do?
- Studentwhat does it eat?
Bugscope TeamI am not sure what kind of beetle this is, but species of beetles eat almost everything. They eat garbage, they eat dead animal bodies, plants, wood, other insects.
- Bugscope Teamconcentrated
- Bugscope Teamcan't spell
- Studentwhat is the chiped of part?
Bugscope Teamthat is where the palp opens up to these setae that are like tastebuds
- Bugscope Teamthis is analogous to the features we saw on the tick
- Studentwhat are the bumps
- Studentwhat are those cracks?
- Studentwere can find this dug
- Studentis the betle big or small?
- Studentcan it smill?
- 11:32 am
- Teacherwhat are YOUR jobs?
Bugscope TeamI train and help people with our electron microscopes that we have. I also help with the sample preparation involved. Scott runs everything in our microscopy suite
- Studentis it color blined
Bugscope TeamMost likely, this beetle can not see in color, probably just in black and gray and white
- Studenthow do you know all this stuff????
Bugscope TeamSome of us have done Bugscope for 10 years, and we have learned a lot during that time. I also have a graduate degree in entomology, so I cheated and didn't just learn it from Bugscope
- StudentWhy is it black and white
Bugscope Teamit's black and white because we are using electrons rather than light to get these images -- the image comes to us as signal rather than light
- Bugscope Teamthis is the mondo bigboy Daddy Praying mantis
- Studentwhat tipe of bug is this?
Bugscope Teamthis is a praying mantis -- another one in the 'scope
- Studentcan we see the moth
Bugscope Teami'm sorry but we dont have a moth in the microscope today
- Studentcan you zoom in at the eye?
- Studentwe just learned about electrons
- Studentwhat is this insect?
- Bugscope TeamAlina is showing us what the inside the vacuum chamber looks like -- those are the samples!
- Bugscope TeamThis is the inside of the microscope
- Studentthat is cool
- Studentthank you alot
- Bugscope Teamat the top is the cone that the electrons come from, and to the right top is where the secondary electrons are collected
- Teacherok - I hate top break this up - but students have to go now
Bugscope TeamNoooo...
- Bugscope TeamThank You for connecting with us today.
- Bugscope Teamoh we are sorry to hear that, but please reapply for bugscope again!
- Bugscope Teamand thank you all for all your great questions
- Bugscope Team:(:(::(
- Bugscope TeamThank you all
- 11:37 am
- TeacherThank you so much for a great session!
- Bugscope Teamthis is where you can go to see your images and the chat: http://bugscope.beckman.illinois.edu/members/2009-006/
- Bugscope TeamThank You!
- Teachergreat! we will post it on the wiki website that we make for this project
