- 2:29pm
- Bugscope Team hey guys!
- Bugscope Team right now we are on a part of a centipede
- Student hey
- Student hey
- Student well hello there
- Student sweeeet
- Student hey
- Bugscope Team super sweeet...
- Bugscope Team Hi Christian, and Sommer, and BML...
- Student wat are we looking at
- Student whats this
- Student ooooooo segmented
- Bugscope Team let us know when you have questions.. like yeah this is a centipede.
- Student looks likes legs to me
- Student i'd say
- Bugscope Team centipedes freak me out. my last apartment was crawling with them. blech.
- Bugscope Team lots of segments, and the last several segments have these little ports in them that we think may be scent glands.
- Student gross
- Student what
- Student i actually love centipedes
- Bugscope Team it is cool to be able to do something with the bugs you find now
- Student too close
- Student tdy
- Bugscope Team how come you like centipedes christian?
- Bugscope Team like catching mosquitos because we know we will be able to use them
- Student can we see it in color?
Bugscope Team well no, that's because the microscope uses electrons to gather the image. electrons are smaller than the waveleght of visible light, so that's why there is no color.
- Student cuz they are awesome
- Bugscope Team cool!
- Bugscope Team Pat if you see a scanning electron microscope image and it is in color it has been false colored.
- Student ohhhhhhhhhh
- Student thanks
- Teacher I would like to look at the head of the milkweed beetle head, but it will not let me
- Student makes sense
- 2:34pm
- Student i want to too
- Bugscope Team try hitting refresh marty...
- Student me three
- Student me four
- Bugscope Team scott is manually moving the scope now. to your location.
- Student what is thaat
- Student what is this
- Student that
- Student its awesome is what that is
- Bugscope Team this is the milkweed bug
- Student nice
- Bugscope Team marty, can you try clicking on the preset again?
- Student that is cool
- Student milkweed
- Student why is it called a milkweed bug?
- Bugscope Team it uses that trunk like thing to suck the wilkweed juices out
- Student what are those antennae like things
- Bugscope Team milkweed*
- Student whats milk weed
- Bugscope Team milkweed is a plant that has seeds in it like dandelion seeds
- Student a plant i think
- Student this is awesome
- Bugscope Team Milkweed pods burst open in the fall and have all of those dandelion like seeds that Cate mentioned.
- Bugscope Team They are weeds, ot most people.
- Student whoa hes got claws
- Student u becha
- Student why are there claw like structures on the legs?
- Bugscope Team and you can see the claws, and the forearms are called tarsi, or tarsal segments, or tarsomeres...
- Bugscope Team a lot of insects have these little claws, and thats what are they, claws
- Bugscope Team there are usually 3 to 5 tarsi.
- Student those are some pretty impressive arms
- 2:39pm
- Student WHOAA
- Bugscope Team marty, great job driving the scope.
- Bugscope Team when you look at the claws on various insects you can often tell whether they will be able to cling to glass or walk on the ceiling.
- Student looks like a dead turtle
- Student earwigs pinch me
Bugscope Team yeah that's its defensive mechanism
- Bugscope Team heh, it does look like a turtle shell doesn't it.
- Bugscope Team Because a little lower than the claw, usually, you may find a pad called the pulvillus, with little stickt setae on it.
- Student how big is a mite???
- Student that is pretty cool how far it is magnified
Bugscope Team this 'scope can go ver VERY high in mag, we've seen things at 200,000x
- Bugscope Team you can see that the mite is over 100 microns long.
- Bugscope Team check out the size bar in the lower left. that is 30 microns
- Student thats really small
- Bugscope Team 100 microns, or 100 micrometers, is one tenth of a millimeter.
- Student what is the white thing on the mite's leg?
- Bugscope Team You can image at higher than 200,000 but collecting useful images stops, usually, at about 200,000x.'
- Teacher can we let benjamin drive
- Bugscope Team sure~
- Bugscope Team benjamin now has control of the microscope
- Bugscope Team ok go ahead benjamin
- Student go gettem ben
- Bugscope Team we want to be able to take images that can be used in research publications, and those need to be high quality.
- Student i think benjamin needs to go back to drivers ed
- Student what are the spikey things
Bugscope Team those are setae or what on humans would be hair
- Bugscope Team benjamin, you are controlling a $750,000.00 microscope!
- Student ouch!
- Student holy cow
- 2:44pm
- Bugscope Team benjamin is doing great!
- Student word
- Bugscope Team or on mammals i should say
- Student thanks
- Bugscope Team they are setae (hairs) that allow the earwig to feel its surroundings
Bugscope Team they have a hard shell around them, the exoskeleton, and they can't feel things the way we do, so they have lots and lots of setae connected to nerves to tell them whats going on around them!
- Student is that a claw or somthing on the mites leg? its white
- Bugscope Team setae help the insects to sense their environment. the setae are attached to nerves under their chetin, whereas humans have nerves in the skin.
- Bugscope Team because insects have exoskeletons -- they have their skeleton on the outside of their body.
- Student what is the smallest bug you have ever used under the microscope
Bugscope Team i think some of the mites we've looked at are the smallest. but scott will know for sure...
- Bugscope Team the exoskeleton is made of chitin, also called cuticle
- Bugscope Team benjamin, you are doing an awesome job, keep it up!
- Bugscope Team chitin, sorry, not chetin.
- Bugscope Team it is much like what your fingernails are made of, or like shrimp shells
- Student new bug!
- Student thanks for the info scotty
- Bugscope Team that is the mouth and tongue of the fly
- Student needle things
Bugscope Team probably mechanosensory setae again, allowing the fly to taste/smell
- Bugscope Team we have researchers here who use chitosan for various things, including (somehow) rendering the chemicals in bombs harmless.
- Student no way
- Bugscope Team chitosan is the same as chitin
- Bugscope Team this is one of the compound eyes
- Bugscope Team you can see it has thousands of facets
- Student thats cool
- Student of wat bug
- Bugscope Team called ommatidia
- Student what shape are those lenses
- 2:50pm
- Bugscope Team this is a fly little big man
- Bugscope Team they are hexagonal
- Student its big man little
- Bugscope Team ommatidia are like lots and LOTS of our eyes!
- Bugscope Team you can go closer to see
- Student easy
- Bugscope Team sorry BML.
- Student its alright S
- Bugscope Team now a little focus
- Student focus it like scotty said
- Bugscope Team see if this fly had bad eye sight, think of all the contact lenses he would need lol
- Bugscope Team it's easy -- you can do it
- Student lol
- Bugscope Team NICE!
- Student Nice
- Student ?
- Bugscope Team good job Benjamin.
- Student nice!
- Bugscope Team you can see a seta on the upper left corner
- Student very nice
- Student this is pretty cool
- Student whats a seta
Bugscope Team it's an insect hair that helps them sense their surroundings
- Bugscope Team We should let Big Man Little drive as well.
- Student bumpy?
- Bugscope Team flies use setae that are on their eyes to help tell them which way the wind is blowing
- Student yea let him
- Student lets let peter pan
- Student would there be a major difference in the fly's eyesight if one of the little eyes didn't work properly?
Bugscope Team good question, but I don't think so, since they have hundreds of them, at least these guys do. now an ant that only has a few ommatidia might be affected a little
- Student i say Kel attempts to drive
- Bugscope Team seta is singular or setae (pronounced see-tee), and they are the fine hairlike projections we see.
- Student no i dont want to drive bml
- Bugscope Team Big Man Little has control now.
- Student bml is not as good as me
- Bugscope Team If you look at the brain of a fruit fly, for example, you can see that most of it is devoted to optics.
- Bugscope Team He has to have time to practice a bit.
- Bugscope Team you can tell how much an insect relies on their eyes by hjow many ommatidia they have, like i mentioned, flies have a lot (giving them almost a 360 degree view) and ants that live underground have only a few, where you can actually try to count them
- Student thats cool is that the seta that is sticking up
- Student ?
- Bugscope Team this eye is very "hairy
- Student but if the flys see in mosaic images and if one piece was missing wouldn't there be a diffence of some kind?
Bugscope Team I'm sure it affects them a little bit, but they have all those other ommatidia to help them piece together the picture as well
- 2:55pm
- Student ok
- Bugscope Team here you see lots of setae sticking up between the ommatidia - opp Rich beat me to it.
- Bugscope Team Benjamin you did a good job driving for sure.
- Student youre right ben i am twice as good
- Student if you say so
- Student what is the debris between lenses
- Bugscope Team if you look at the micron bar on the lower left you can imagine how big bacteria are -- they are generally (bacilli) two microns long.
- Student thats true.
- Bugscope Team but I am not an expert on insect eyes, so don't take my word on everything
- Student lol alright
- Bugscope Team this debris so far is just that
- Bugscope Team :)
- Bugscope Team on the eyes
- Student XD
- Bugscope Team Big Man Little you can click another preset if you want.
- Student pollen is my downfall
- Student whats that?
- Student oh duh pollen
- Bugscope Team but I think a lot of pollen looks like this
- Bugscope Team Should we let Sommer drive?
- Student what is the insect that holds the pollen
- Student no
- Student im ok
- Student yeah let her drive
- Bugscope Team if you take the mag down you can tell what this is
- Student no
- 3:00pm
- Bugscope Team Christian you have control now dude.
- Student Go Christian Go
- Student Big man little did way worse than me
- Student haha
- Student easy kids
- Student Scott thanks for giving me the oppurtunity
- Bugscope Team take the mag down so you can see where we are -- I made the preset but forget what the critter was.
- Student christian hasnt even passed his drivers test yet
- Student whats the ridge of stuff right next to those upper "hairs"
- Bugscope Team No problemo BML.
- Student ?
- Student ooo good one
- Student or not
- Student it really meant a lotr to him Scott
- Student lot
- Bugscope Team scope moved real far for this preset, that's why it took so long.
- Student his life has been changed forever
- Student ooo
- Student so all the bugs are under the scope at the same time
- Student looks like its smiling
- Bugscope Team Sommer I am not sure just what was there on the ridge. A lot of setae and those little bumps -- we don't always recognize what we see.
- Student im just randomly clicking
- Student gotcha
- Bugscope Team You can see the compound eyes, streamlined into the shape of the head.
- Student compound eyes or simple
- Bugscope Team actually now only to the far right
- Student wher r u eyes
- Student oh compound
- Student good ? felipe
- Student i think its time for someone else to drive
- Student the*
- Student nose it not me
- Bugscope Team these are compound and I don't think ladybugs have simple eyes
- Student nose
- Bugscope Team ok, i just gave control to rich sutherland
- Bugscope Team rich, youre THE MAN! take us away.
- Student ha
- Student yea rich
- Student it aint a stick shift
- Student yeah take us away
- Student rich wat
- Student could you zoom in below the claw look thing?
- Student richmond
- Student looking*
- 3:05pm
- Student not sunday
- Student how big is the microscope
Bugscope Team it's about the size of a desk, here is a picture of it: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
- Bugscope Team wasps and bees often have to tell their nestmates where they've been
- Student where are the eyes located
- Student sides
- Student what are we looking at in the center
- Student o
- Bugscope Team the eyes are as Felipe says, on the sides there
- Student thanks alex
- Bugscope Team you cannot see one just now
- Bugscope Team but to the right
- Student y do they have to tel their nestmates where they've been?
- Bugscope Team or left
- Student tell*
- Student meg po you havent said much
- Bugscope Team we have to put liquid nitrogen into the scope from time to time. it's very interesting to work around such a scope.
- Student thank you
- Student peace thanx
- Student thank you
- Student thanks
- Student thanks u guys are awesome
