• Bugscope Teamhey welcome!
• TeacherHello, we are ecited!
• Bugscope TeamHello, Mr D!
• 1:51 pm
• Bugscope TeamThis is a butterfly or moth scale. On a different insect.
• Bugscope TeamYou have the con, Mr. D!

• Bugscope TeamYou can choose from among the presets on the left side of the screen or change the mag, etc. on the place where we are, currently.

• Bugscope TeamClaw and tarsi.
• Bugscope TeamPlease let us know when you have questions.
• TeacherWhat is the purpose of the tarsi?
  Bugscope Teamthat is the part of the leg where the claw is attached. it uses the claw to grab onto things, like our hands do
• 1:56 pm
• Bugscope Teamthe tarsi are the final joints on the arm
• Bugscope TeamHi Mr. D!
• Bugscope TeamBeing an insect is kind of like wearing a suit of armor all of the time. The exoskeleton has to have joints in it so the bee, in this case, can move its arms the way it wants to.

• Bugscope Teamthe thing in the middle that is lighter than everything else is the rostrum, or piercing mouthpart.

• Bugscope TeamThe reason it is not as dark as everything else is that it is a bit loose, not as conductive as the other parts of the insect, so it is charging up with electrons.
• Bugscope TeamPollen!

• Bugscope TeamIt's a true bug, a hemipteran, but we're not sure what species it is.

• Bugscope TeamCate is looking it up

• Bugscope TeamThe pollen is covered in a film of some sort.
• 2:02 pm

• TeacherWhat kind of bug is this?
  Bugscope TeamLooks like a burrower bug...it eats sap through roots

• Bugscope TeamThe Rove beetle eats other insects, among other things.

• Bugscope TeamThe background with all of the depressions in it is the double-stick carbon the insects and other arthropods are stuck to.
• 2:07 pm

• Bugscope TeamMr D are you there with your class or are you working remotely?
• TeacherSome students are remote, some are here.

• Bugscope TeamTop of the head here we see where an antenna was, and a pretty much broken off antenna.

• Bugscope TeamWith flies, the male's eyes are often fairly close together compared to the female's eyes. Like Mikhail Baryshnikov vs. Uma Thurman.

• Bugscope Teami helped with focus a little. should update in a sec
• Bugscope TeamThis is one edge of the mouthparts, kind of dried up.

• Bugscope TeamDebris and setae.

• Bugscope Teamyou can see ridges on the seta
• 2:12 pm
• Bugscope Teamthe scale bar is at 1 micrometer which means we are seeing things that are nanometers in size
• Bugscope Teamalmost 80,000 times magnified

• Bugscope Teamit's fun to see how high magnified you can go
• Bugscope TeamInsects and many other arthropods with exoskeletons have various types of setae that stick out of the exoskeleton. The setae are sensory: hot/cold, touch, also with the ability to taste and smell.
• Bugscope TeamDifferent setae for different senses.

• Bugscope Teamthere are parts of a facet of the compound eye here which are sub micron in size
• Bugscope TeamThe compound eye facets are called ommatidia.

• Bugscope Teamit's drifting, but one of those round parts are around 230 nanometers
• Bugscope TeamWhen Cate says 'micron,' a micron is a millionth of a meter, or a thousandth of a millimeter. Bacteria are often around 2 microns long.
• Bugscope Teamthese are like the cones and rods in our eyes

• Bugscope TeamSo submicron is in the nano range, as in nanometers, which are a billionth of a meter.
• Bugscope TeamHere you see an ant's claw and two tarsi.

• Bugscope TeamTotally cool.

• 2:17 pm
• Bugscope TeamSee if you can focus on the tiny round things. They may be brochosomes.

• Bugscope TeamBrochosomes look like little whiffle balls, kind of. They're usually around 250 to 400 nm in diameter, and they are produced by leafhoppers.

• Bugscope TeamBecause other insects sometimes hang out with leafhoppers, or sometimes they eat them, we find brochosomes on lots of insects.

• Bugscope TeamBut I'm sorry, not here, not yet.

• Bugscope TeamWhen ticks get really big and sometimes break open, they can actually heal themselves; put their exoskeleton ack together.
• Bugscope Team'back"

• Bugscope TeamThe bacteria we see here are kind of dried and dirty.
• 2:23 pm

• Bugscope TeamYou can see a few small setae (little 'hairs') sticking out of the compound eye.
• Bugscope Teamnot quite where we are now...

• Bugscope Teamgood job driving

• Bugscope Teamhere you see setae and microsetae

• TeacherWhat is a spiracle?
  Bugscope Teamit is a breathing port hole
  Bugscope Teaminsects can open and close their setae
  Bugscope Teamthey don't really breath like we do with our mouths, but through holes in their exoskeleton

• Bugscope TeamIf we had a cockroach in the microscope, where there is a very good vacuum, like inside a lightbulb, the cockroach could close its spiracles and 'hold its breath' that way.
• 2:28 pm
• Bugscope TeamThis is the coolest ant, even with a broken mandible.

• Bugscope Teampillbug AKA rolypoly

• Bugscope TeamDid you mean to go here?

• Bugscope Teamwhen we put insects on the stub, on the doublestick carbon tape, we often put some silver paint under them as well, to help ensure that they're electrically grounded.

• Bugscope TeamThis is a really gnarly tick with a film of bacteria on its head.

• Bugscope TeamThe center part of the head is called the 'capitulum,' and the sides are palps that fold down when the tick bites you.
• Bugscope Teamthe moth
• 2:33 pm

• Bugscope Teamits antennae and some of its setae are charging up with electrons; that's why they seem to be glowing.

• Bugscope Teamthe samples in the chamber are coated with 10 or 20 nanometers of gold-palladium to make them conductive. But it doesn't always work well.

• Bugscope Teamthe stinger is partially broken. when it stings the two sides slide like an electric carving knife.
• Bugscope TeamThe stinger comes out of the end of the abdomen, like a bee stinger.

• 2:39 pm

• Bugscope TeamUma

• Bugscope TeamI'm sorry -- about the tick, the central part of the capitulum is called the hypostome -- that is the part that sticks into your skin.

• TeacherThank you so much, we have to go now! We really enjoyed this!
• Bugscope TeamThank you!
• Bugscope TeamGlad to have you on board.
• Bugscope TeamThanks Mr. D!
• Bugscope Teamthanks for joining us today
• Bugscope Teamhere's the view from the top inside the microscope
