• 7:43 am
• Bugscope Teamsample is pumped down and we are making presets for today's session

• 7:48 am

• 8:14 am

• 8:21 am

• 8:30 am

• 8:36 am

• 8:42 am
• Bugscope Teamwe are all set and ready to go!
• 8:58 am
• Teacherwe are having some technology issues this morning.... sorry
• Bugscope TeamGood morning BCMS!
• Teachergood morning \
• Bugscope Teamlet me know if you need any help
• Bugscope Teamto get to the presets, click on the left blue arrow to get to the preset screen. The you should be able to select an area of interest to go to
• Teacherare you getting my messages?
• Bugscope TeamYes I can seeyou
• TeacherI think we are up and running now.... what type of insect is it
• Bugscope Teamthis is a backswimmer. they like to be near or on water

• Bugscope Teamthey swim in the water upside down.
• 9:04 am

• Bugscope Teamyou can see one of its legs is broken off. Insects get very brittle and break easily after they die

• Bugscope Teamthey are predatory and float by controlling the size of an air bubble
• Teacherwhat are the bristles for?

• Bugscope Teamthe bristles are for sensory purposes
• Teacherwhere is the air bubble?
• Bugscope Teamsince insect all have an exoskeleton, they need these hairs (setae) to sense their environments and themselves
• Bugscope Teami believe it is in their abdomen
• Teacherdo the backswimmers have eyes
• Bugscope Teami don't think backswimmers need air bubbles since they are on their backs.

• Bugscope Teamyes they are kind of streamlined with their heads
• Bugscope Teambut the eyes are part of the rounded part

• 9:09 am
• Bugscope Teamyou can kind of see the compound eyes there, the part that looks kind of checkered
• Teacherwhy do they have all those hairs on their head
• Bugscope Teamthe eyes are further to the NE

• Bugscope Teami'm not sure why there is a big patch of fur concentrated in that area, but they are most likely for sense of touch
• Bugscope Teamthose hairs are to sense their environment, since they're in the water, i would guess that they are using those to sense movements on the water surface, alerting them to potential predators

• Teacherwhat is the scientific name for the roly poly?
• Bugscope Teamarmadillidiidae
• Teacherwhat are those little spikes on the arm?
• Bugscope Teamit is sometimes also called a pillbug or sowbug, depending on which variety it is
• Bugscope Teammore bristles for sense of touch!
• Teacherdo they roll up for protection?
• Bugscope Teamyup. it is mostly for protection.

• Bugscope Teamexoskeletons are like wearing a suit of armor. You really can't feel anything through it, or tell if you are brushing up against something. That's why they have all those bristles
• 9:14 am
• Teacherhow do they intake food?

• Bugscope Teamthey have a little mouth, part of which is broken open up north
• Teacherwhat is the smallest and biggest thing yall have have prepared?
• Bugscope TeamThey use palps near their mouths, those are used to taste and handle the food.

• Bugscope Teamin the microscope today? it would probably be the moth as the biggest and a wasp as the smallest

• Bugscope Teamever with bugscope would probably be a cicada as the largest, and I'm not sure what would be smallest
• Teacherwhat is the donut looking circle on their head? is it there eye?
• Bugscope Teamthis is the head of a mosquito. the donut shape thing is the pedicel, or the base of the antennae
• 9:19 am
• Bugscope Teamjoseph is an actual entomologist. I help other students to image their samples, which isn't always insects.
• Bugscope Teamthe antennae unfortunately seems to be broken off

• Bugscope Teamsurrounding that is the compound eye.. you can see how much of the face it's taking up
• Bugscope Teamthe pedicels do look like eyes, though
• Teacherwhat are those leafy looking things
• Teacher?*
• Bugscope Teamthose leafy things or feathery things are actual scales
• Bugscope Teamthe seemingly random flakes you see all over its body are scales. mosquitoes have scales, similar to the scales of a butterfly/moth's wings
• Teacherwhat are the scales used for and why isn't it all over

• Bugscope Teamthey're most likely for escaping

• Bugscope Teamhaving scales that easily detach helps the escape from things like a spider web.
• TeacherWhat type of visiion does it have, like some has thermal vison?
• Bugscope Teamif a mosquito gets caught in a spider web, sometimes they can shake a few loose to escape
• Bugscope Teamon a live mosquito, they will be all over, the scales you see here in the sample have fallen off most likely in transport and preparation, as they are pretty easily detachable
• Bugscope Teammost insects see colors and UV
• 9:24 am
• Teacherhow does their brain comprehend that many images at once?

• Bugscope Teammosquitos know where food is through chemicals. They are attracted to carbon dioxide and lactic acid. Food being us or other mammals
• Teacherdo you know how many frames do they see
• Teacherin their eyes
• Bugscope Teamfrom what I understand, the images are sent back to the brain and reassembled there like a giant puzzle. It's kind of similar to what our eyes do, but we only have 2 images to deal with

• Bugscope Teami don't know that, but the image that they see resembles what you might consider a very low resolution picture

• Bugscope Teamsomewhat like a mosaic
• Bugscope Teamit looks like there are a couple hundred facets

• Teacherwhat is the hole like thing

• Bugscope Teamthat is where a palp broke off. Palps help insects to move around or taste food
• Bugscope Teamthat hole like thing is another part that has broken off, looks to the the palps
• Teacherwhere are their taste buds?
• Bugscope Teamyou can now see the scales a little more up close
• Teacherhow long is their life span?
• 9:30 am
• Bugscope Teamthey don't really have tastebuds like people do. They have special hairs that help them with reading chemical information

• Bugscope Teama week or two i think.
• Bugscope Teami heard on the radio today that there are now spiders that are big enough to catch bats, and, due to interbreeding with other spiders, are found on every continent except antarctica.

• Bugscope TeamThis is thankfully not one of those
• Teacherwhy would they bite you?
• Bugscope Teama spider?

• Teacheryes

• Bugscope Teamself defense
• Bugscope Teammost people get bitten when they unwittingly disturb or pester a spider
• Teacherwhy are banana spiders webs yellow?

• 9:35 am
• Bugscope Teamspider webs are made of proteins that are liquid while they are still in their bodies. They become more solid when exposed to air
• Teacherhow do they breathe?
• Bugscope Teamspiders can also eat their webs if they get too hungry
• Bugscope Teami think the colour is from the chemicals in the web?

• Bugscope Teamwe don't see many, or any, banana spiders up here in cold Illinois
• Bugscope Teamthey breathe through spiracles
• Teacherwhat are the side effects of a spider bites

• Bugscope Teamthese are holes in the sides of the spider that is specifically made to let air in and out

• Bugscope Teamthere is a tracheal system that brings oxygen to each cell
• Bugscope Teamapparently their yellow webs attract bees
• Bugscope Teamthere are many different effects
• Bugscope Teamthat depends on their toxins
• TeacherHow do they create their webbing?
• Bugscope Teamfor example, the bites of brown recluse can lead to necrosis, or tissue cell death

• Bugscope Teamspiders have spinnerets at the end of their abdomens which guides the spider silk
• 9:40 am

• Bugscope Teamall the insects are sitting on double stick carbon tape, which is what you see in the background

• Bugscope Teamthe carbon helps ground the electrons

• Teacherwhy is their 'exoskeleton' layered?
• Bugscope Teamthe silk is stored as a liquid in a gland, and as it moves along a duct, the silk gets formed
• Bugscope Teamthe panels help the insect to be flexible- so they can bend how they want
• Bugscope Teamthe exoskeleton is "layered" for expansion and contration

• Bugscope Teamyou only really see this layering in the abdomen. expansion and contraction are essential to breathing, blood pumping and regulating body heat

• Bugscope Teamthe abdomen would normally be more round than this. It dried out a little
• Teachercan they sting repeaditly
• 9:45 am
• Bugscope Teamyellow jackets can sting repeatedly. most other wasps will not be able to pierce human skin
• Bugscope TeamThis is a very small wasp, not sure wha it is
• TeacherTHANK YOU CATE AND JOSEPH!!!
• Bugscope Teamyou're welcome!
• Bugscope Teamthank you. I hope you and your class had fun
• Bugscope Teamthanks for joining us
