Bugscope Teamokay had to add this last preset
Bugscope Teamso now you have control of the 'scope
Bugscope TeamPlease let us know when you have questions, and let us know if you have any trouble driving the 'scope.
9:34 am

Bugscope Teamthe tiny particles we see on the moth scales are brochosomes, which are produced solely by leafhoppers
Bugscope Teamthey are very small, as you can tell from the micron bar -- they are nanoparticles
TeacherDo you have a stink bug?
Bugscope Teamunfortunately no, the closest we could come was an assassin bug. They are both true bugs
Bugscope Teamthey look similar
TeacherCan we look at an assassin bug?
Bugscope Teamthey are both Hemiptera. they have piercing mouthparts

Bugscope Teamthis is the assassin bug
10:06 am
Bugscope Teamyou can see the dome-like eyes on either side of the head, and you can see its proboscis, coming right down the middle of the head
Bugscope Teamstink bugs, as Cate said, look like these guys
Bugscope TeamBUGS12345 has control of the microscope and can drive it as well as click on any of the presets to get the microscope to drive to those places

Bugscope Teamyou can either click on another preset which are located to the left or you can change the magnification or drive around by clicking in the direction you want to go
10:11 am
Teacherhow do we look at another area?
Bugscope Teamif you click on the white arrow in the blue circle on the left, you can see what choices you have, and all you need to do is click on one

Bugscope TeamCool!
Teacherthanks
Bugscope Teamnow you can see one of the spiders, and you can see its 8 eyes as well as its chelicerae

Bugscope Teamthe tiny setae help it stick to surfaces
Bugscope Teamand this is a very fierce-looking stinger
Bugscope Teamthis is a big wasp stinger, belongs to a cicada killer wasp
10:16 am
Bugscope Teamit is blunt and would really hurt
Bugscope Teamstingers are modified ovipositors, and sometimes they still do lay eggs as well as sting
Bugscope Teamovipositors are used by some insects to deposit their eggs inside branches, or inside leaves, or in some cases inside other bugs, like caterpillars, or cicadas
Bugscope Teamcicada killers really do kill cicadas; they sting them to paralyze them, and then they lay their eggs inside them
10:22 am
Bugscope Teamthey carry the cicada to their nest, which is in the ground
Bugscope Teamactually I just read that in this case the cicada killer lays a single egg on top of the paralyzed cicada, and when the egg hatches the larva eats the cicada.
Bugscope TeamHeya---I can't login as an admin, so I will be a Guest,
Bugscope Teamhi Annie, we are looking at a cicada killer's stinger
10:27 am
Bugscope Teamcool
Bugscope TeamMcIntyre please let us know if you are having any problems with the connection, or if you have any questions for us at all.
10:35 am

Bugscope TeamI took us to the diatoms on the caddisfly larva
Bugscope Teamthey look kind of like boats
Bugscope Teamcaddisflies, like mosquitoes, mayflies, and stoneflies, live part of their life underwater
Bugscope Teamso they get diatoms, which are silica-shelled unicellular algae, stuck to their bodies
Bugscope Teamthere are many shapes of diatoms

Bugscope Teamyou can see the ommatidia (which are the eye facets) and there is also some debris on top of the eye, maybe plant material
10:47 am
Bugscope TeamMoths and spiders (those that are active at night) have a layer of tracheae at the base of their eyes. This layer is shiny and reflective--when photons of light enter the eye, they bounce off of that reflective layer and are eventually captured by the light sensitive cells in the eye. This is why moth eyes glow red when you shine a flashlight on them.
Bugscope TeamI am full of facts now that I teach general biology!
Bugscope Teamis that kind of similar to a cat's eyes shining when light hits them in the dark
Bugscope TeamIt is EXACTLY like a cat's eye--just with a different mechanism for reflecting the light. It is a great case of analogous structures and convergent evolution.
Bugscope TeamThe inside of the eye of a nocturnal animal is a beautiful reflective blue color. The insides of human eyes are solid black.
Bugscope TeamThe blue color is important because it reflects the highest energy light.
Bugscope TeamI took us to the mosquito head

Bugscope TeamMr. Mosquito
10:52 am
Bugscope Teamyes a male, we can tell that because they have frilly antennae
Bugscope TeamOnly female mosquitoes bite
Bugscope Team`test
Bugscope TeamLogged in as an admin
Bugscope Teamyou should see Public/Private
11:00 am
Bugscope TeamYes, I can login now
Bugscope TeamWe are going to shut down now -- unless there is something more we can do for McIntyre.
Bugscope TeamThank you for connecting with us today.

Title	Bugs
Insects	stink bug
Description	Since we've recently been innovated with stink bugs in our school & surrounding neighborhoods, we thought it would be great to study them. I teach science & we use microscopes in our Diversity of Life Unit. I'd love to integrate Bugscope into this unit.
