- Bugscope Team sample is in 'scope and pumping down for today's session
- Bugscope Team now we're making presets...
- Guest thanks dudes
- Bugscope Team np!
- Bugscope Team welcome to Bugscope!
- Bugscope Team Welcome back!
- Bugscope Team let us know if you have any questions
- Bugscope Team we are ready to roll anytime
- Teacher We are ready when you are!
- Bugscope Team this is a palp, which is an accessory mouthpart
- Bugscope Team super cool
- Bugscope Team you have control of the microscope
- Bugscope Team you may select from any of the presets to get the microscope to drive to that position
- Teacher We think it looks like a dragon!
Bugscope Team Cate and I thought it looked like that too!
- Bugscope Team taking the magnification down like this gives us an idea of where it is and what it is
- Teacher What are those "hairs" sticking out?
Bugscope Team those 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 Team the longer hairs are more likely mechanosensory-for sense of touch
- Bugscope Team the little things that looked like dragon's teeth are chemosensors that help the insect smell and taste its food
- Bugscope Team this is a cute little ladybug larva
- Bugscope Team it's hard to make out its exact shape because it has covered itself with its favorite food, which is aphids
- Bugscope Team ladybugs are predators as both larvae and adults
- Bugscope Team they are actually good, because they eat aphids, which would otherwise attack your plants
- Teacher What are those points on the right side?
Bugscope Team those are spines on the larva's back -- they are protection against being eaten by birds, for example
- Bugscope Team this is another baby ladybug
- Bugscope Team we see the spines much better here
- Teacher That one looks like it has a hole, or is it just broken off?
Bugscope Team it is indeed broken
- Teacher Is there any special reasons for the "ridges" look?
- Bugscope Team they may look like that because they are dried and a bit shrunken
- Bugscope Team ladybugs taste bad, and the bad taste combined with their red warning colors helps protect them from being eaten
- Bugscope Team you 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 Team now we see the antennae better
- Bugscope Team see the facets of the compound eye?
- Bugscope Team the individual lenses are called ommatidia
- Teacher About how many facets are there?
Bugscope Team looks like a few hundred on each compound eye here
- Bugscope Team with some ants we can actually count them; with some large hornets, however, there could be 30,000 facets per compound eye
- Bugscope Team some flying insects have three extra eyes, in addition to their compound eyes
- Bugscope Team the extra eyes are on the top of the head, and they are called ocelli
- Teacher What was in the background on the first view, a leaf??
Bugscope Team in the background of the beetle palp, or the grasshopper?
- Teacher this one of the grasshopper
- Bugscope Team that is silver paint -- the smoother part
- Bugscope Team the part with all of the dots in it is carbon tape with little craters in it
- Bugscope Team this is another palp, way up close
- Teacher What exactly is that?
Bugscope Team the palps help move around or taste food. the little things at the end are like tastebuds
- Bugscope Team there are usually two sets of palps, and they are like accessory mouthparts, extra feelers that help the insect eat
- Bugscope Team this is lily pollen, and this time the background is a dried aphid
- Bugscope Team the things that look like carved potatos are pollen grains
- Bugscope Team pollen grains come in many different shapes; from our experience most lily pollen looks like this
- Bugscope Team here we can see that the ant's compound eyes have many fewer facets than many of the other insects we've seen today
- Bugscope Team these are the mandibles, or jaws
- Bugscope Team they are serrated to help them cut things and chew
- Bugscope Team insect mandibles open left and right, like a gate
- Bugscope Team in people the lower jaw is called the mandible, and the upper jaw is called the maxilla
- Bugscope Team the eye!
- Bugscope Team ants get much more information using their antennae than they get from their eyes
- Bugscope Team the antennae are jointed, and they join the head at these ball and socket joints
- Bugscope Team this is the beetle we started out with. see the palp we were looking at in the middle and a bit to the left?
- Bugscope Team the palps are sometimes called mandibular and maxillary palps
- Bugscope Team the thing that looks like a smile, or the inside of the submarine sandwich, is another set of sensory setae, like tastebuds
- Bugscope Team these are kind of odd little salt crystals
- Bugscope Team most salt is smooth
- Bugscope Team this is really cool
- Bugscope Team it is rare that we see scales on insects other than butterflies, moths, silverfish, and mosquitoes
- Bugscope Team scales are here instead of setae
- Bugscope Team scales are modified setae
- Teacher Is it's body covering a little different?
Bugscope Team yes it is!
Bugscope Team the 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 Team this is a borer, and we see right away how its head is streamlined
- Bugscope Team so cute!
- Bugscope Team we can see its little pointy mandibles
- Bugscope Team see the jaws (mandibles) here? one of them is chipped. they open right and left like gates
- Bugscope Team yay bacteria!
- Bugscope Team bacteria!
- Bugscope Team haha
- Teacher Is there a reason the top looks more rough?
Bugscope Team sometimes 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
- Teacher And what is the bump?
Bugscope Team it'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 Team there are probably two more behind it; they usually form triangles on the top of the head
- Bugscope Team now 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 Team sometimes we also see what look like pores in the front of the head
- Bugscope Team this is one of the claws
- Bugscope Team now we see two sets of claws, one on each limb
- Bugscope Team the 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
- Bugscope Team the 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'
- Teacher Is that pollen or something in the middle?
- Bugscope Team I think that is the hard part of the stinger, which comes out of the opening when it is used
- Bugscope Team yay!
- Bugscope Team Cate and I like the dragon.
- Bugscope Team and this borer!
- Bugscope Team insects do not have skin like we do; instead they have a kind of shell, which is like if we were wearing armor
- Bugscope Team the 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 Team sure that sounds grea
- Bugscope Team great
- Teacher Thank you so much! We learned a lot! We are just showing the kindergarten teacher and principal some of our favorites!
Bugscope Team Thank You Everyone!
- Teacher The kindergarten teacher said she was going to have nightmares!
Bugscope Team ohhh....
- Teacher We enjoyed it though! We think the Borer2 is cute!
Bugscope Team awesome!
- Bugscope Team yeah i thought so too!
- Teacher Good bye!
- Bugscope Team Good Bye!
- Bugscope Team Thank you!
