• 7:05 pm
• Bugscope Teamthis is part of the fascicle of an aphid
• Bugscope Teamsimilar to that of a mosquito
• Bugscope Teamkind of a surprise

• 7:12 pm
• Bugscope Teamhi jude!
• Bugscope Teamwelcome to bugscope!
• Bugscope TeamJude!
• Bugscope TeamWelcome to Bugscope!
• Teacherhi we just joined - where do aphids live?
• Bugscope Teamon plants, on leaves, all over the place
• TeacherDo they survive the harsh winters?
• Bugscope Teamno not really; they are softbodied
• Bugscope Teamthey also migrate long distances by riding on the wind
• Teacherwhat do they eat?
  Bugscope Teamwell, they are a MAJOR pest to cultivated plants, one of the worst
• Bugscope Teamthey use their proboscises to penetrate leaves and suck the juices out
• Bugscope Teamso, they eat plant matter
• Bugscope Teamthey are vegans... :)
• Bugscope Teamwe have a rare view this evening of some of the components of the proboscis; they are very much like those of mosquitos
• Bugscope Teamoops, i just unlocked the session now, sorry about that. you should see the microscope controls. you are welcome to control the scope as you wish
• Bugscope Teammosquitos have a bundle of mouthparts called the fascicle, and apparently aphids do as well

• Bugscope Teamyou can also click on any preset to goto that location

• Bugscope Teamthose are the ocelli on top of a fruit fly
• Bugscope Teamfruit fly's head
• 7:17 pm
• Bugscope Teamthis scope can magnify up to 800,000x, but for these insects, the range of 40-40,000x is best
• Bugscope Teamsee the aphid, above?
• Teachermaybe
• Teacherno
• Bugscope Teamaphids don't air-dry well
• Bugscope Teamscreen resolution?
• TeacherI thought they ride the wind
  Bugscope Teamyes, they use the wind to migrate, i believe
• Bugscope Teamha
• Bugscope Teamonce they die they shrivel up is what I meant ;)
• Bugscope Teamemoticon for you
• Bugscope Teamthey can also survive on transported plant materials, and can spread that way too
• Bugscope TeamI doubt if they would worry about something that small
• Bugscope Teamthey are super tiny little dudes
• Bugscope Teamlike a snack maybe
• Bugscope Teami don't see bats as a major predator of aphids, just beetles, wasps and some spiders
• Teacheranother group is comming over to talk to you
• Bugscope Teamthey have little exhaust pipes on the back end called cornicles
• Bugscope Teamnotice the scale bar in the bottom left of the image, that can give you an idea of size
• Bugscope Teamsome cornicles produce nectar for ants to drink
• Bugscope Teamand some produce wax that hardens in air and immobilizes ants, permanently
• Teacherwe are workin in groups
• Bugscope Teamwe can have up to 20-25 students log in at the same time. but too many logins means too many questions, and the chat can get overloaded
• Bugscope Teamcan you see the whole screen and all of the controls?
• Bugscope Teamah, okay, no problemo
• 7:22 pm
• Teacherwhat kind of bugs are we looking at?
• Bugscope Teamyou may choose from among the presets on the right side of this chat box, and you may also drive if you wish
• Bugscope Teamthis is a fruit fly on the lower left, and an aphid in the upper right
• Bugscope Teamfruit fly, aphid, ladybugs, mosquitos, beetles
• Bugscope Teamthe bubbles in the background are the sticky tape that we put the insects on
• Bugscope Teammoth is there too but charging too much to image well
• Teacherwhat is a aphid?
  Bugscope Teamthey are very small plant eating insects, from the superfamily Aphidoidea

• Bugscope Teaman aphid is a tiny bug that infests plant leaves, usually; it sucks the juices from plants

• Bugscope Teamthis is a ladybug
• Bugscope Teamanother one...

• Bugscope Teambeetle head

• Bugscope Teamend of the world
• Bugscope Teamwhen using click to drive, click once to start moving, then clic again to stop
• Bugscope Teamif you get lost, you can always click on a preset to go there

• Bugscope TeamHi all, sorry I'm a little late.

• Bugscope Teamthis is another aphid, and you can see its mouthparts, similar to those of a mosquito
• 7:27 pm
• Bugscope Teamthe strand-like elements are usually closely appressed into what is called, in mosquitos, a fascicle
• Bugscope Teamtwo of them cut, apparently, and one is the siphon
• Bugscope Teamthe proboscis is pointed right toward us
• Bugscope Teamhello miek, welcome to bugscope
• Bugscope Teamwelcome to Bugscope!
• Studentwe are looking at this thru miek not jude in error. please guide us so we can move the images
• Bugscope Teamyou have control now miek
• 7:32 pm
• Bugscope Teami just cancelled the jude session from before, so you can login now, ah there you are!
• Bugscope TeamJude is back!
• Bugscope Teamjude, do you want control, or does miek?
• Bugscope Teamwe can give control to anyone who is logged in
• Studentplease zoom in on the eyes
• Bugscope Teamyou have the ability to drive
• Bugscope Teamyou can do it
• Studentwhat kind of bug is this
• Bugscope Teamthis is an aphid
• Bugscope Teamyou can use click to center and then you can change the mag
• Bugscope Teamit is an aphid

• Bugscope Teamthis is cool
• Bugscope Teamthis is the mouth
• Bugscope Teamand those things that are whirling out of it are mouthparts that normally stick into leaves
• Bugscope Teamhi cristy!
• Bugscope Teamyou rarely see them
• Bugscope TeamJude we gave you control of the 'scope
• Bugscope TeamHi Cristy!
• Teacherhi bug man
• Bugscope Teamthese images are black and white because they come from an electron microscope, which uses electrons to gather the image, not light.
• Teacherinteresting
• 7:37 pm
• Bugscope TeamThis is the proboscis of an aphid
• Bugscope Teamif you have any questions please feel free to ask away
• Bugscope Teamyou have the ability to drive to wherever you want on the stub
• Teacherwe do not have control anymore
• Teacherthe control panels are gone on the right side
• Bugscope TeamJude has control. Do you want it?
• Teacherwhat kind of bugs are those
• Bugscope Teamnow you have control

• Bugscope Teamnow you can see the inside of the scope
• Teacheranks
• Bugscope Teamwith all the insects on the stage
• Teacher*thanks
• Bugscope Teama moth, a cricket, some ladybugs, some mosquitos

• Bugscope Teamcool
• Bugscope Teamyou can select from any of the presets
• Bugscope Teamyou don't have to stay here
• Bugscope Teamand you can drive to other places as well

• Bugscope Teamthat preset moved after we made it

• Teacher that pollen?
• Teacher*is that pollen?
• Bugscope Teamthis is the claw of a small wasp?
• Bugscope Teamoops
• 7:42 pm
• Bugscope Teamum it is mostly dirt

• Bugscope Teamyay this is cool too
• Bugscope Teamthis is the head of a fruit fly
• Bugscope Teamthe antennae are busted -- not all of the antenna is there
• Teacherthis is a new group
• Bugscope Teamyou can see it has lots of setae on the surface of its compound eye
• Bugscope Teamyou can take the mag up to see the individual ommatidia -- the facets of the eye

• Bugscope Teamha guess where this salt came from
• Bugscope Teamit is wild-lookin'
• Bugscope Teammost salt is just regular old cubes
• TeacherMexico?
• Bugscope Teamyeah good guess
• Bugscope Teamit comes from Wendy's restaurants
• Teacherhaha

• Bugscope Teamwe don't know why it looks like that but we think maybe it has an anticaking agent in it
• 7:48 pm
• Teacherwhat is the proboscis?
  Bugscope TeamIn insects, proboscis refers to the tube-like mouthparts that are used for feeding.
• Bugscope Teamthose leaf-like things are scales on the mosquito's proboscis
• Bugscope Teamthe proboscis is the probing mouthpart
• Bugscope Teaman elephant's proboscis is its trunk
• Teacherwhere did this mosquito come from?
• Bugscope TeamBut that doesn't hold true for other animals, as Scott points out.
• Bugscope Teamthe mosquito proboscis is a sheath that holds the stylets and the little siphon that the blood goes up
• Bugscope Teamwe found this evening that aphids have very similar internal mouthparts

• Bugscope Teamsimilar to those of mosquitos
• Bugscope TeamMakes sense, since they are basically mosquitoes on plants.
• Bugscope Teamheh yeah
• Bugscope TeamAlbeit permanent ones. Ugh, what a thought.
• Bugscope Teamthey have a tiny siphon, and they have at least two kind of laciniae

• Bugscope Teamhere we see part of a wasp's head
• Teachersick
• Bugscope Teamyou can make out the hexagonal ommatidia
• Teachertotally
• 7:53 pm
• Bugscope Teamif you take the mag down you can see the whole head, to the left
• Teacheri am not sure if i want to
• Bugscope TeamI can do it for you

• Teacheris this mold from wendy's also?
• Bugscope Teamno that would not be nice
• Teacherthat is good to know.
• Bugscope Teamthere is mold in the air all of the time

• Teacherhow big is an aphid in real lire?
• Teacherlife?
• Bugscope Teammaybe a couple of mm long
• Teacherthanks
• Bugscope Teamthey are different sizes of small
• Bugscope TeamSometimes you run into a hefty one that's maybe half a centimeter.
• Teacherwe are done for tonight...thank you so very much.
• Bugscope Teamsome function as cows to ants
• Bugscope TeamThank You!
• Bugscope TeamSee you next time!
