- Bugscope Teamhey guys!
- Bugscope Teamright now we are on a part of a centipede
- Studenthey
- Studenthey
- Studentwell hello there
- Studentsweeeet
- Studenthey
- Bugscope Teamsuper sweeet...
- Bugscope TeamHi Christian, and Sommer, and BML...
- Studentwat are we looking at
- Studentwhats this
- Studentooooooo segmented
- Bugscope Teamlet us know when you have questions.. like yeah this is a centipede.
- Studentlooks likes legs to me
- Studenti'd say
- Bugscope Teamcentipedes freak me out. my last apartment was crawling with them. blech.
- Bugscope Teamlots of segments, and the last several segments have these little ports in them that we think may be scent glands.
- Studentgross
- Studentwhat
- Studenti actually love centipedes
- Bugscope Teamit is cool to be able to do something with the bugs you find now
- Studenttoo close
- Studenttdy
- Bugscope Teamhow come you like centipedes christian?
- Bugscope Teamlike catching mosquitos because we know we will be able to use them
- Studentcan we see it in color?
Bugscope Teamwell 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.
- Studentcuz they are awesome
- Bugscope Teamcool!
- Bugscope TeamPat if you see a scanning electron microscope image and it is in color it has been false colored.
- Studentohhhhhhhhhh
- Studentthanks
- TeacherI would like to look at the head of the milkweed beetle head, but it will not let me
- Studentmakes sense
- 2:34 pm
- Studenti want to too
- Bugscope Teamtry hitting refresh marty...
- Studentme three
- Studentme four
- Bugscope Teamscott is manually moving the scope now. to your location.
- Studentwhat is thaat
- Studentwhat is this
- Studentthat
- Studentits awesome is what that is
- Bugscope Teamthis is the milkweed bug
- Studentnice
- Bugscope Teammarty, can you try clicking on the preset again?
- Studentthat is cool
- Studentmilkweed
- Studentwhy is it called a milkweed bug?
- Bugscope Teamit uses that trunk like thing to suck the wilkweed juices out
- Studentwhat are those antennae like things
- Bugscope Teammilkweed*
- Studentwhats milk weed
- Bugscope Teammilkweed is a plant that has seeds in it like dandelion seeds
- Studenta plant i think
- Studentthis is awesome
- Bugscope TeamMilkweed pods burst open in the fall and have all of those dandelion like seeds that Cate mentioned.
- Bugscope TeamThey are weeds, ot most people.
- Studentwhoa hes got claws
- Studentu becha
- Studentwhy are there claw like structures on the legs?
- Bugscope Teamand you can see the claws, and the forearms are called tarsi, or tarsal segments, or tarsomeres...
- Bugscope Teama lot of insects have these little claws, and thats what are they, claws
- Bugscope Teamthere are usually 3 to 5 tarsi.
- Studentthose are some pretty impressive arms
- 2:39 pm
- StudentWHOAA
- Bugscope Teammarty, great job driving the scope.
- Bugscope Teamwhen 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.
- Studentlooks like a dead turtle
- Studentearwigs pinch me
Bugscope Teamyeah that's its defensive mechanism
- Bugscope Teamheh, it does look like a turtle shell doesn't it.
- Bugscope TeamBecause a little lower than the claw, usually, you may find a pad called the pulvillus, with little stickt setae on it.
- Studenthow big is a mite???
- Studentthat is pretty cool how far it is magnified
Bugscope Teamthis 'scope can go ver VERY high in mag, we've seen things at 200,000x
- Bugscope Teamyou can see that the mite is over 100 microns long.
- Bugscope Teamcheck out the size bar in the lower left. that is 30 microns
- Studentthats really small
- Bugscope Team100 microns, or 100 micrometers, is one tenth of a millimeter.
- Studentwhat is the white thing on the mite's leg?
- Bugscope TeamYou can image at higher than 200,000 but collecting useful images stops, usually, at about 200,000x.'
- Teachercan we let benjamin drive
- Bugscope Teamsure~
- Bugscope Teambenjamin now has control of the microscope
- Bugscope Teamok go ahead benjamin
- Studentgo gettem ben
- Bugscope Teamwe want to be able to take images that can be used in research publications, and those need to be high quality.
- Studenti think benjamin needs to go back to drivers ed
- Studentwhat are the spikey things
Bugscope Teamthose are setae or what on humans would be hair
- Bugscope Teambenjamin, you are controlling a $750,000.00 microscope!
- Studentouch!
- Studentholy cow
- 2:44 pm
- Bugscope Teambenjamin is doing great!
- Studentword
- Bugscope Teamor on mammals i should say
- Studentthanks
- Bugscope Teamthey are setae (hairs) that allow the earwig to feel its surroundings
Bugscope Teamthey 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!
- Studentis that a claw or somthing on the mites leg? its white
- Bugscope Teamsetae help the insects to sense their environment. the setae are attached to nerves under their chetin, whereas humans have nerves in the skin.
- Bugscope Teambecause insects have exoskeletons -- they have their skeleton on the outside of their body.
- Studentwhat is the smallest bug you have ever used under the microscope
Bugscope Teami think some of the mites we've looked at are the smallest. but scott will know for sure...
- Bugscope Teamthe exoskeleton is made of chitin, also called cuticle
- Bugscope Teambenjamin, you are doing an awesome job, keep it up!
- Bugscope Teamchitin, sorry, not chetin.
- Bugscope Team it is much like what your fingernails are made of, or like shrimp shells
- Studentnew bug!
- Studentthanks for the info scotty
- Bugscope Teamthat is the mouth and tongue of the fly
- Studentneedle things
Bugscope Teamprobably mechanosensory setae again, allowing the fly to taste/smell
- Bugscope Teamwe have researchers here who use chitosan for various things, including (somehow) rendering the chemicals in bombs harmless.
- Studentno way
- Bugscope Teamchitosan is the same as chitin
- Bugscope Teamthis is one of the compound eyes
- Bugscope Teamyou can see it has thousands of facets
- Studentthats cool
- Studentof wat bug
- Bugscope Teamcalled ommatidia
- Studentwhat shape are those lenses
- 2:50 pm
- Bugscope Teamthis is a fly little big man
- Bugscope Teamthey are hexagonal
- Studentits big man little
- Bugscope Teamommatidia are like lots and LOTS of our eyes!
- Bugscope Teamyou can go closer to see
- Studenteasy
- Bugscope Teamsorry BML.
- Studentits alright S
- Bugscope Teamnow a little focus
- Studentfocus it like scotty said
- Bugscope Teamsee if this fly had bad eye sight, think of all the contact lenses he would need lol
- Bugscope Teamit's easy -- you can do it
- Studentlol
- Bugscope TeamNICE!
- StudentNice
- Student?
- Bugscope Teamgood job Benjamin.
- Studentnice!
- Bugscope Teamyou can see a seta on the upper left corner
- Studentvery nice
- Studentthis is pretty cool
- Studentwhats a seta
Bugscope Teamit's an insect hair that helps them sense their surroundings
- Bugscope TeamWe should let Big Man Little drive as well.
- Studentbumpy?
- Bugscope Teamflies use setae that are on their eyes to help tell them which way the wind is blowing
- Studentyea let him
- Studentlets let peter pan
- Studentwould there be a major difference in the fly's eyesight if one of the little eyes didn't work properly?
Bugscope Teamgood 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
- Studenti say Kel attempts to drive
- Bugscope Teamseta is singular or setae (pronounced see-tee), and they are the fine hairlike projections we see.
- Studentno i dont want to drive bml
- Bugscope TeamBig Man Little has control now.
- Studentbml is not as good as me
- Bugscope TeamIf you look at the brain of a fruit fly, for example, you can see that most of it is devoted to optics.
- Bugscope TeamHe has to have time to practice a bit.
- Bugscope Teamyou 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
- Studentthats cool is that the seta that is sticking up
- Student?
- Bugscope Teamthis eye is very "hairy
- Studentbut if the flys see in mosaic images and if one piece was missing wouldn't there be a diffence of some kind?
Bugscope TeamI'm sure it affects them a little bit, but they have all those other ommatidia to help them piece together the picture as well
- 2:55 pm
- Studentok
- Bugscope Teamhere you see lots of setae sticking up between the ommatidia - opp Rich beat me to it.
- Bugscope TeamBenjamin you did a good job driving for sure.
- Studentyoure right ben i am twice as good
- Studentif you say so
- Studentwhat is the debris between lenses
- Bugscope Teamif you look at the micron bar on the lower left you can imagine how big bacteria are -- they are generally (bacilli) two microns long.
- Studentthats true.
- Bugscope Teambut I am not an expert on insect eyes, so don't take my word on everything
- Studentlol alright
- Bugscope Teamthis debris so far is just that
- Bugscope Team:)
- Bugscope Teamon the eyes
- StudentXD
- Bugscope TeamBig Man Little you can click another preset if you want.
- Studentpollen is my downfall
- Studentwhats that?
- Studentoh duh pollen
- Bugscope Teambut I think a lot of pollen looks like this
- Bugscope TeamShould we let Sommer drive?
- Studentwhat is the insect that holds the pollen
- Studentno
- Studentim ok
- Studentyeah let her drive
- Bugscope Teamif you take the mag down you can tell what this is
- Studentno
- 3:00 pm
- Bugscope TeamChristian you have control now dude.
- StudentGo Christian Go
- StudentBig man little did way worse than me
- Studenthaha
- Studenteasy kids
- StudentScott thanks for giving me the oppurtunity
- Bugscope Teamtake the mag down so you can see where we are -- I made the preset but forget what the critter was.
- Studentchristian hasnt even passed his drivers test yet
- Studentwhats the ridge of stuff right next to those upper "hairs"
- Bugscope TeamNo problemo BML.
- Student?
- Studentooo good one
- Studentor not
- Studentit really meant a lotr to him Scott
- Studentlot
- Bugscope Teamscope moved real far for this preset, that's why it took so long.
- Studenthis life has been changed forever
- Studentooo
- Studentso all the bugs are under the scope at the same time
- Studentlooks like its smiling
- Bugscope TeamSommer 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.
- Studentim just randomly clicking
- Studentgotcha
- Bugscope TeamYou can see the compound eyes, streamlined into the shape of the head.
- Studentcompound eyes or simple
- Bugscope Teamactually now only to the far right
- Studentwher r u eyes
- Studentoh compound
- Studentgood ? felipe
- Studenti think its time for someone else to drive
- Studentthe*
- Studentnose it not me
- Bugscope Teamthese are compound and I don't think ladybugs have simple eyes
- Studentnose
- Bugscope Teamok, i just gave control to rich sutherland
- Bugscope Teamrich, youre THE MAN! take us away.
- Studentha
- Studentyea rich
- Studentit aint a stick shift
- Studentyeah take us away
- Studentrich wat
- Studentcould you zoom in below the claw look thing?
- Studentrichmond
- Studentlooking*
- 3:05 pm
- Studentnot sunday
- Studenthow big is the microscope
Bugscope Teamit's about the size of a desk, here is a picture of it: http://www.itg.uiuc.edu/ms/equipment/microscopes/esem/
- Bugscope Teamwasps and bees often have to tell their nestmates where they've been
- Studentwhere are the eyes located
- Studentsides
- Studentwhat are we looking at in the center
- Studento
- Bugscope Teamthe eyes are as Felipe says, on the sides there
- Studentthanks alex
- Bugscope Teamyou cannot see one just now
- Bugscope Teambut to the right
- Studenty do they have to tel their nestmates where they've been?
- Bugscope Teamor left
- Studenttell*
- Studentmeg po you havent said much
- Bugscope Teamwe have to put liquid nitrogen into the scope from time to time. it's very interesting to work around such a scope.
- Studentthank you
- Studentpeace thanx
- Studentthank you
- Studentthanks
