• 10:33 am
• Bugscope Teamsample is pumping down in the 'scope
• 10:40 am

• Bugscope Teamhello KKIV!

• 10:45 am

• 10:52 am

• 10:57 am

• 11:04 am

• 11:10 am

• TeacherHello

• Bugscope TeamHello!
• Bugscope TeamWelcome to Bugscope!
• Bugscope Teamwe've been working on presets, just about ready
• TeacherOk

• Bugscope Teamwe are ready to roll
• TeacherOk, what are we looking at?
• Bugscope Teamyou have control of the 'scope

• Bugscope Teamthis is a ladybug claw

• 11:15 am

• Bugscope Teamyou can click on any of the presets, on the lefthand screen, and make the 'scope drive to that position on the stub

• Bugscope Teamthis now is one of the tarsi
• Bugscope Teamyou can see little bristle-like setae
• Teacherthey would like to know what a tarsi is
• Bugscope Teamon the surface of the cuticle
• Bugscope Teamtarsi are the last five segments of the limb -- the distalmost segments, furthest from the body
• TeacherOk, like "tarsals"
• Bugscope Teamthe individual tarsi are also called tarsomeres
• Bugscope Teamthey're segmented for flexibility
• Teacherthey would like to know if you wear glasses :)

• Bugscope Teamhaha Yeah I wear glasses, don't go outside much
• TeacherHa!

• Bugscope Teamwe're microscopists...

• Teachercan you see the eyes from this view
• Bugscope Teamthis is pretty funny -- we didn't expect the ladybug's face to be fully covered with fungus and bacteria
• 11:20 am

• Bugscope Teamthe eyes are covered as well -- all we can see are a bare palp, and to the left, one of the forelimb claws

• Bugscope Teamwhen Cate puts the samples together, she cannot always see, of course, what an individual specimen will be like at the micro level
• Bugscope Teamgood news is this all probably grew on it after it died

• Teacheris the one to the right another lady bug?
• Bugscope Teamthe background here is carbon doublestick tape and silver paint, to hold the bugs down and also carry the charge from the electron beam to ground

• Bugscope Teamit is a larva. A baby ladybug

• Bugscope Teamladybugs are predators as larvae and as adults

• Bugscope Teamsome of these features are there to dissuade other predators from eating the larva
• Teacherwhat are the "claw-like" things here

• Bugscope Teamonce ladybugs become adults, their coloration serves as a warning that they do not taste good
• Bugscope Teamthey protect them from being eaten. Kind of like the spikes some caterpillars have
• 11:25 am
• Bugscope Teamwith some larvae (caterpillars) the spikes or spines exude toxins or irritants
• Teacherdo ladybugs give any sort of "liquid" that protects them by warning predators

• Bugscope Teamyes they are kind of like stink bugs in that they ooze a little bit of stinky/yucky liquid

• Bugscope Teamthis is a parasitoid wasp, which lays its eggs in the eggs or larvae of other insects

• Bugscope Teamwhen the eggs hatch they can eat their way out

• Bugscope Teamthe parasitic wasp guy told us that there is a parasitic wasp not only for every species of insect, but also for every life stage of insect

• Teacheryuck
• Bugscope TeamI am sitting next to the microscope and just moved us to this spiracle

• 11:30 am

• Bugscope Teamone of the ways spiders are unlike insects is that their head and thorax are fused into a 'cephalothorax,' which is hardened, but the rest of the spider -- the abdomen, for example, is soft and shrivels up when the spider dies

• Bugscope Teamthis one has variously sized eyes

• Teacherwhat is on his eye
• Bugscope Teami think it's one of the setae, or hairs, sitting on it
• Bugscope Teamsome spiders see quite well, but many do not and rely more on their ability to sense vibration, using many of the setae that we see (the 'hairs')
• Bugscope Teamor it's a piece of plant material
• Bugscope Teamthose are simple eyes, not the compound eyes we find on many insects
• Teacherhow can you tell if the spider is male or female

• Bugscope Teamsometimes you can tell by their overall size, and sometimes you can tell if you can see their pedipalps; in the males the pedipalps are kind of swollen at the ends, like boxing gloves

• 11:35 am
• Bugscope Teamin female spiders, which can be far larger than males, the pedipalps are smaller

• Bugscope Teampalps help bugs taste or move around food

• Bugscope Teamin spiders the male palps serve another purpose as well

• Bugscope Teamthese ommatidia -- the individual facets of the compound eye -- are shrunken -- they've lost internal liquids that normally support them when the insect is alive

• Bugscope Teammany flying insects like flies, bees, wasps, and moths have three ocelli -- simple eyes -- on the tops of their heads in addition to the compound eyes
• Teacherthey would like to know if bees or wasps really die after they sting
• Bugscope Teamhoneybees die after they sting mammals
• Bugscope Teamonly honeybees do, and it's only when they sting a mammal

• Bugscope Teamthey have barbs in their stinger that get caught in our skin
• 11:41 am

• Bugscope Teamwhen honeybees sting other insects, their stingers do not get caught and pulled out like they do when they sting thicker mammalian skin
• Bugscope Teamskin is too thick for the bee to safely pull out the stinger.

• Bugscope TeamWhen they pull away, they leave the stinger and a venom sac behind, which actually continues to pump venom into the wound a little bit

• Bugscope Teamwhen the stinger gets pulled out, along with the venom sac, it leaves a big hole in the honeybee's body, and the honeybee bleeds to death
• Bugscope Teamthis is the head of a borer beetle

• Bugscope Teamwe're looking right at one of its eyes, obscured by the antenna
• Bugscope Teamnow we see the mouthparts, including four palps and two mandibles
• TeacherDo you know what makes a person allergic to a bee sting?
• Bugscope Teamin humans the lower jaw is the mandible, and the upper jaw is called the maxilla
• Bugscope Teammainly it's the histamine in their venom that people are allergic to

• 11:46 am
• Bugscope Teampeople have different responses to being stung, and some are fine with a few stings but can develop stronger reactions once they've been stung more times
• Bugscope Teamin insects the mandibles are on the sides; they open like a gate

• Bugscope Teamthe palps, as Cate said earlier, help the insect taste and also manipulate its food
• Bugscope Teamthis is ugly
• Teacheryes it is

• Bugscope Teamcraneflies look like industrial-sized mosquitoes

• Bugscope Teambut they do not bite

• Bugscope Teami know growing up people told me crane flies were male mosquitos

• Teacher:)

• 11:51 am
• Bugscope Teamonly the female mosquitoes take blood meals
• Bugscope Teamand there are species of mosquitoes -- none in the U.S. -- in which neither the males nor females bite
• Teacherwish we had those

• Bugscope Teamthey are called Something (Genus) molestus, and apparently they are annoying but do not bite.

• Teacherdo the males still bite even if they don't drink the blood

• Bugscope Teamsome insect and arthropod claws open and close, and inside the forearm (the tarsus) there is a tendon called the unguitractor that makes that work

• Bugscope Teamno they don't

• Bugscope Teamfemales only need blood to help them reproduce

• Bugscope Teammale mosquitoes either live on nectar or do not eat at all; in a number of adult male fly species the males do not eat, ever. some do not have mouths

• TeacherFSM?
• Bugscope Teamflying spaghetti monsters
• 11:56 am
• Teacher?

• Bugscope Teamwe are not sure what these are -- they seem to be very small plants that will presumably settle somewhere and growe
• Bugscope Teamit's just that they resemble the flying spaghetti monster, in a way
• Teacherok

• Bugscope TeamFSMs are a satirical take on the concept of intelligent design

• Teacherwhat kind of insect is this

• Bugscope Teamthis is on the borer beetle I think
• Bugscope Teamwhen we look at a beetle's limbs, we can make an educated guess whether it will be able to climb on vertical surfaces of stick to the ceiling
• Bugscope Teamyes this is a borer, of some sort

• Bugscope Teaminsects that can climb walls or walk on glass have a pad called a pulvillus on at least each limb, and often more than one
• Bugscope Teamthe pulvillus has lots of tiny sticky setae on it, called tenent setae
• Teacherwell, thank you very much. My class just left but they wanted me to ask one more question (they are quite the clowns)... what are your favorite colors and does Scot date Cate? Ha... it's getting harder and harder to teach I tell you. :P
• 12:02 pm
• Bugscope Teamhahaha interesting questions
• Teacherlike a borer that gets into a cottonwood tree?
• Bugscope Teammy favorite color is blue
• Bugscope Teamand no we don't date
• Bugscope Teamusually blue, for me, as well
• Bugscope Teamyes like a Cottonwood borer
• TeacherOk, thank you.
• Bugscope Teamhaha Sure!
• Bugscope TeamThank You!
