- Bugscope Teamsample is in 'scope and pumping down for today's session
- 11:56 am
- 12:02 pm
- 12:07 pm
- Bugscope Teamnow we're making presets...
- 12:16 pm
- 12:22 pm
- Guestthanks dudes
- 12:28 pm
- Bugscope Teamnp!
- 12:42 pm
- Bugscope Teamwelcome to Bugscope!
- Bugscope TeamWelcome back!
- Bugscope Team let us know if you have any questions
- Bugscope Teamwe are ready to roll anytime
- 12:55 pm
- TeacherWe are ready when you are!
- Bugscope Teamthis is a palp, which is an accessory mouthpart
- Bugscope Teamsuper cool
- Bugscope Teamyou have control of the microscope
- Bugscope Teamyou may select from any of the presets to get the microscope to drive to that position
- TeacherWe think it looks like a dragon!
Bugscope TeamCate and I thought it looked like that too!
- Bugscope Teamtaking the magnification down like this gives us an idea of where it is and what it is
- TeacherWhat are those "hairs" sticking out?
Bugscope Teamthose are what they look like- hairs, but on insects we call them setae. They help the insect sense what is going on around it- like sense of touch or taste/smell
Bugscope Teamthe longer hairs are more likely mechanosensory-for sense of touch
- Bugscope Teamthe little things that looked like dragon's teeth are chemosensors that help the insect smell and taste its food
- Bugscope Teamthis is a cute little ladybug larva
- 1:00 pm
- Bugscope Teamit's hard to make out its exact shape because it has covered itself with its favorite food, which is aphids
- Bugscope Teamladybugs are predators as both larvae and adults
- Bugscope Teamthey are actually good, because they eat aphids, which would otherwise attack your plants
- TeacherWhat are those points on the right side?
Bugscope Teamthose are spines on the larva's back -- they are protection against being eaten by birds, for example
- Bugscope Teamthis is another baby ladybug
- Bugscope Teamwe see the spines much better here
- TeacherThat one looks like it has a hole, or is it just broken off?
Bugscope Teamit is indeed broken
- 1:05 pm
- TeacherIs there any special reasons for the "ridges" look?
- Bugscope Teamthey may look like that because they are dried and a bit shrunken
- Bugscope Teamladybugs taste bad, and the bad taste combined with their red warning colors helps protect them from being eaten
- Bugscope Teamyou can see this grasshopper's compound eye, some of its palps, and the bases of its antennae,which are directed back, down and to the left
- Bugscope Teamnow we see the antennae better
- Bugscope Teamsee the facets of the compound eye?
- Bugscope Teamthe individual lenses are called ommatidia
- TeacherAbout how many facets are there?
Bugscope Teamlooks like a few hundred on each compound eye here
- 1:11 pm
- Bugscope Teamwith some ants we can actually count them; with some large hornets, however, there could be 30,000 facets per compound eye
- Bugscope Teamsome flying insects have three extra eyes, in addition to their compound eyes
- Bugscope Teamthe extra eyes are on the top of the head, and they are called ocelli
- TeacherWhat was in the background on the first view, a leaf??
Bugscope Teamin the background of the beetle palp, or the grasshopper?
- Teacherthis one of the grasshopper
- Bugscope Teamthat is silver paint -- the smoother part
- Bugscope Teamthe part with all of the dots in it is carbon tape with little craters in it
- Bugscope Teamthis is another palp, way up close
- TeacherWhat exactly is that?
Bugscope Teamthe palps help move around or taste food. the little things at the end are like tastebuds
- Bugscope Teamthere are usually two sets of palps, and they are like accessory mouthparts, extra feelers that help the insect eat
- 1:16 pm
- Bugscope Teamthis is lily pollen, and this time the background is a dried aphid
- Bugscope Teamthe things that look like carved potatos are pollen grains
- Bugscope Teampollen grains come in many different shapes; from our experience most lily pollen looks like this
- Bugscope Teamhere we can see that the ant's compound eyes have many fewer facets than many of the other insects we've seen today
- Bugscope Teamthese are the mandibles, or jaws
- Bugscope Teamthey are serrated to help them cut things and chew
- Bugscope Teaminsect mandibles open left and right, like a gate
- Bugscope Teamin people the lower jaw is called the mandible, and the upper jaw is called the maxilla
- Bugscope Teamthe eye!
- Bugscope Teamants get much more information using their antennae than they get from their eyes
- 1:21 pm
- Bugscope Teamthe antennae are jointed, and they join the head at these ball and socket joints
- Bugscope Teamthis is the beetle we started out with. see the palp we were looking at in the middle and a bit to the left?
- Bugscope Teamthe palps are sometimes called mandibular and maxillary palps
- Bugscope Teamthe thing that looks like a smile, or the inside of the submarine sandwich, is another set of sensory setae, like tastebuds
- Bugscope Teamthese are kind of odd little salt crystals
- Bugscope Teammost salt is smooth
- 1:26 pm
- Bugscope Teamthis is really cool
- Bugscope Teamit is rare that we see scales on insects other than butterflies, moths, silverfish, and mosquitoes
- Bugscope Teamscales are here instead of setae
- Bugscope Teamscales are modified setae
- TeacherIs it's body covering a little different?
Bugscope Teamyes it is!
Bugscope Teamthe scales all over the body likely help with thermoregulation, so the insect does not get cold so quickly; they also likely give the insect a shiny appearance; and scales often protect their bearers from spider webs
- Bugscope Teamthis is a borer, and we see right away how its head is streamlined
- Bugscope Teamso cute!
- Bugscope Teamwe can see its little pointy mandibles
- 1:31 pm
- Bugscope Teamsee the jaws (mandibles) here? one of them is chipped. they open right and left like gates
- Bugscope Teamyay bacteria!
- Bugscope Teambacteria!
- Bugscope Teamhaha
- TeacherIs there a reason the top looks more rough?
Bugscope Teamsometimes that roughness gives the insect a shiny look. there is a bump in the very middle which is a simple eye used for navigation. there should be 2 more that we can't see behind it
- 1:37 pm
- TeacherAnd what is the bump?
Bugscope Teamit's an ocellus! it's a simple eye that registers light and dark and helps the insect keep track of where it is with respect to the sun and the sky.
Bugscope Teamthere are probably two more behind it; they usually form triangles on the top of the head
- Bugscope Teamnow we see the serrated jaws (mandibles) and two sets of palps, and two antennae, two compound eyes, and the single ocellus that is in view
- Bugscope Teamsometimes we also see what look like pores in the front of the head
- Bugscope Teamthis is one of the claws
- Bugscope Teamnow we see two sets of claws, one on each limb
- Bugscope Teamthe middle part, between the claws, is called an 'arolium.' it can be inflated to fill a small crevice and help the insect stick to a surface
- 1:42 pm
- Bugscope Teamthe tip of the stinger/ovipositor may be split so it can slide, side buy side, to cut into whatever the insect is laying its eggs in
- Bugscope Team'side by side'
- TeacherIs that pollen or something in the middle?
- Bugscope TeamI think that is the hard part of the stinger, which comes out of the opening when it is used
- Bugscope Teamyay!
- Bugscope TeamCate and I like the dragon.
- Bugscope Teamand this borer!
- 1:47 pm
- Bugscope Teaminsects do not have skin like we do; instead they have a kind of shell, which is like if we were wearing armor
- Bugscope Teamthe tiny hairs we call setae stick through the armor, or shell -- which is actually called the exoskeleton -- so the insect can sense its environment
- Bugscope Teamsure that sounds grea
- Bugscope Teamgreat
- TeacherThank you so much! We learned a lot! We are just showing the kindergarten teacher and principal some of our favorites!
Bugscope TeamThank You Everyone!
- TeacherThe kindergarten teacher said she was going to have nightmares!
- TeacherWe enjoyed it though! We think the Borer2 is cute!
- Bugscope Teamyeah i thought so too!
- TeacherGood bye!
- Bugscope TeamGood Bye!
- Bugscope TeamThank you!
