- Bugscope Teamsetting up...
- 1:03 pm
- 1:15 pm
- Bugscope TeamHello! We are ready to go, a bit early.
- Bugscope TeamCubbie you should have control if you want to try driving.
- Bugscope TeamAlso please let us know when you have questions.
- Bugscope Teamthe presets Cate made a few minutes ago are on the lefthand side -- choices for you to make.
- 1:22 pm
- Bugscope TeamWe can give control to wil+una if you would like.
- Bugscope Teamthis is one of the adult tick's claws
- Bugscope Teamit has the hook parts that we see, and the other part may be able to swell to help the tick to hold onto something.
- 1:27 pm
- Bugscope Teamthe little black slit is where the Haller's organ may be found. That is what allows the tick to 'smell' the air and determine if someone is close. We think the Haller's organ can sense carbon dioxide that people and animals breathe out.
- Bugscope Teamthis is the underside of the head of a ground beetle
- Bugscope Teamit should have four palps that help it taste prospective food
- GuestCool
- Bugscope Teambut it looks like a couple of palps are missing; they also help manipulate things the insect may be thinking about eating
- Bugscope Teamyou can also see the mandibles, folded over each other
- Bugscope Teamthe bumpy background is the double stick carbon tape we stick the samples to
- Bugscope Teamwith the ladybug's face we can also see its compound eyes
- 1:33 pm
- Bugscope Teamthe mandibles are forked at the end; you can see them at the top in the middle
- Bugscope Teamone of the little pads we see, which are covered with tenent setae, is called the pulvillus
- Bugscope Teammandibles are the jaws of the insect
- Bugscope Teammany insects have pads like that
- Bugscope Teamthey open out like a gate, instead of down like ours
- GuestWhat are the mandibles?
Bugscope TeamMandibles are mouthparts.
- Bugscope Teamthe lower jaw bone in a human is called the mandible; the upper part, which is part of your skull, is called the maxilla
- Bugscope Teamthe eye facets are called ommatidia
- GuestWhat is the maxilla
- Bugscope Teamthis is a closeup of a compound eye
- Bugscope Teamit is kind of dirty
- 1:38 pm
- Bugscope Teamcompound eyes are often round, or rounded, which permits the insect to have close to a 360-degree view of what is around it
- GuestWhere is the compound eye?
- Bugscope Teammaxilla is the top part of the jaw
- Bugscope Teaminsects can also see light in the ultraviolet range, which we cannot see unless we have an ultraviolet light
- Bugscope Teamthe compound eye are usually on the sides of the head. with flying insects, they can take up more room on the head. ants that spend most of their time in the ground may have small compound eyes, or no eyes at all
- Bugscope Teamin the top part of this view we see part of a ball and socket joint
- 1:43 pm
- Bugscope Teamadult ticks have eight legs; juvenile ticks have only six legs until they have grown and moulted into the adult phase
- GuestWow! I didn't know that.
- Bugscope Teamthe tick's head is called the capitulum; it has palps on both sides that fold down when it sticks the central part of the head -- the hypostome -- into your skin.
- Bugscope Teamwe can see the recurved spines that help the hypostome stick into your skin
- Bugscope Teamthe other side is also rough, but not like this side
- Bugscope Teamwe can see the top part of the hypostome now
- 1:48 pm
- GuestWhat is the hypostome?
- Bugscope Teamif we look closely at the tick's belly we can see that it is folded multiple times so that it can expand
- Bugscope Teamthe hypostome is the part in the middle with the spines
- GuestCool!
- Bugscope Teamnow we can see the infoldings of the underside of the tick's body
- GuestWow.
- Bugscope Teamand some mold spores that likely came along when the dead tick was in storage
- Bugscope Teamticks can be broken open when they are swollen with blood, but that does not always kill them; they can reassemble themselves
- 1:54 pm
- Bugscope Teamthe little spines we see on insects and comparable arthropods are called setae, and the larger ones are often sensory
- GuestWhy is the tree bug's claw so pointy?
Bugscope Teamit can open and close to hold onto things; being pointy is helpful, like the difference between a fork and a spoon/
- Bugscope Teaminsects and comparable arthropods have an exoskeleton, which is kind of like a coat of armor.
- GuestCan tree bug's claws help it to climb trees?
- Bugscope Teamso it is super helpful to have little setae sticking through the exoskeleton to help the insect sense its world, like what is touching it; some of those setae, for example at the joint of an arm, let the insect know that its arm is working as intended.
- Bugscope Teamyes the claws will help climb trees and grab onto things
- 2:00 pm
- Bugscope Teamthe ladybug has little vacuum cleaner nozzles on its face; not sure what they do, but they are likely chemosensory
- GuestARe you readyy for the next slide?
Bugscope TeamSure!
- Bugscope Teamwe can show you what the sample looks like from the side, inside the vacuum chamber of the scanning electron microscope.
- Bugscope Teamthat is the vacuum chamber
- Bugscope Teamthis is an image of the sample from above
- Bugscope Teamlet us know if you want to see those again
- 2:05 pm
- GuestOkay....
- Bugscope Teampillbug
- Bugscope Teamwoodlouse
- Bugscope Teamrolypoly
- Bugscope Teamthey have little pointy claws
- GuestWhere did you get the Rolypoly, woodlouse, and the pillbug? I don't have them on my slides.
- Bugscope Teamthey're called isopods because they little feet ('pods') are all the same ('iso')
Bugscope Teamoops 'their' little feet
- GuestCool.
- Bugscope TeamWe found the ladybug in our building, on the stairs. Something had started to chew on it after it died/\
- 2:10 pm
- Bugscope Teamtrue bugs are called Hemiptera
- Bugscope TeamIt means something like 'half wing'
- Bugscope Teamthey have pointy piercing and sucking mouthparts
- Bugscope Teama bedbug is a true bug
- GuestWow
- Bugscope Teamthe little hole, or pore, that we see is where the Haller's Organ is, and we are looking at that organ
- Bugscope Teamthat is what helps the tick sense CO2
- GuestCool
- Bugscope Teamand this is a bonus that Cate mounted on the stage for us -- we're looking at the end of a staple
- 2:15 pm
- Bugscope Teamsorry for some reason the image had gone black
- Bugscope Teamit looks like the beetle has a t-shirt on with hair sticking out of the top
- GuestThat is okay.
- Bugscope Teamyou can see the eyes on both sides of the head
- Guestfor some reason for me it isn't black.
Bugscope Teamwe changed it back
- Guestokay..
- Bugscope Teamah this is cool
- GuestThis is so cool!
- Bugscope TeamSo these are wing scales from a butterfly
- Bugscope Teamthey reflect colors that we may not be able to see
- GuestWow!
- Bugscope Teamalso -- you know how if you rub a butterfly's wings, or a moth's wings, how the fine powder comes off of them?
Bugscope Teamthat fine powder is these things -- the scales we are looking at
- 2:21 pm
- GuestIs it because of.... some sort of light that we can't see?
Bugscope Teamthey are kind of like those lenticular postcards that show different images when you tilt them
- Bugscope TeamBecause of the very fine spacing, the ridges we see reflect different wavelengths of light.
- Bugscope Teamthis is salt -- sodium chloride -- which forms cubic crystals
- GuestSalt crytals aren't bugs
- GuestWhat do salt crystals have to do with bugs?
Bugscope Teamwe just like to throw them on the stub because they are small and easy to add to the sample
- Bugscope Teampollen is sometimes found on bugs, of course -- like bees
- Bugscope Teamthis is lily pollen
- Bugscope TeamBack to what we were talking about earlier -- the wing scales. We know they come off easily. If you were a butterfly or moth or even a mosquito, and you flew into a spider web, you might be able to get away by leaving your scales stuck to the web.
- 2:26 pm
- Bugscope TeamSilverfish have tiny silver scales.
- GuestReally?
Bugscope Teamyes.
- Bugscope Teamthe pointy mouthpart we see is often called a rostrum/
- Bugscope Teamit can pierce things like seeds and suck out liquid
- Bugscope Teamthey can also pierce other insects
- Bugscope Teamand bedbugs have those same kind of piercing mouthparts that let them drink your blood
- Bugscope TeamCate had to leave early.
- GuestThank you for the cool and intresting pictures.
- Bugscope TeamThank you!
- Bugscope TeamThis is fun for us. The chat and some of the images we took will be archived on the Bugscope website.
- GuestI really appreicate that! And also thank you telling me all the intresing facts.
- 2:31 pm
- Bugscope TeamThank you!
- Bugscope TeamSee you next time!
- GuestI am scared of incests but this is a cool way of learning about them while not touching them.
- GuestSee you next time!
- GuestBye!
