- Guesthi guys!
- Guestwhat bug are we looking at??
- Guesthello??
- Guestis any1 there?
- Bugscope Teamthese are spider mites
- 2:08 pm
- Guesto hok
- Bugscope Teamthese are on a leaf
- Bugscope Teamsorry we arent always looking at the screen right now
- Bugscope Teamalex you there
- Bugscope Team?
- Guestok
- Guestdo you have a slide of a dust mite?
Bugscope Teamwe dont have any dust mites today, the only mites are the red spider mites. dust mites are also harder to find because they are soft bodies so they dont dry very well for the microscope
- Guestok
- Bugscope Teamwe have a mosquito, owlfly larvae, spider, wasp, butterfly wing, salt
- Bugscope Teamand a housefly
- Bugscope Teamand a couple ants
- Guestcould we see a wasp?
- Bugscope Teamso here we can see the wasp head
- Bugscope Teamyou can see the one of the compound eyes wraps around the head
- Guestwow
- Bugscope Teamand it has a lot of hairs
- 2:13 pm
- Guestdo those hairs have a name?
Bugscope Teamhairs on an insect are called setae (or seta for singular)
- Bugscope Teamit also has some big jaws
- Bugscope Teamwe technically arent supposed to call them hairs since hairs are for mammals
- Bugscope Teamnow we can see inside the 'scope chamber where the sample is kept in a vacuum
- Bugscope Teamwe have the insects mounted on a 1 3/4 inch aluminum stub
- Bugscope Teamthe setae (pronounced see-tee) allow the insect to feel whats going on around them through their tough exoskeleton
- Guestoh
- Guestdo humans have hair on their head and arms and legs for the same reason?
- Bugscope Teamwe are using a scanning electron microscope (SEM) to image these insects today, which uses electrons and not light. this is why the images look black and white
- Bugscope Teamsome of the hairs serve the same reason. We have hairs to keep us warm for the most part, but they are connected to nerves just like the insects. The insect setae serve multiple purposes like tasting/smelling, feeling, sensing hot/cold
- Guestok
- Guestmm this is kind of random
- Bugscope Teamthey have more specialized hairs because they have something similar to a suit of armor, we dont have to have hairs like that because we have soft skin that allows us to feel more
- 2:19 pm
- Bugscope Teamhere we are zoomed in on the compound eye of the wasp
- Bugscope Teamthere are even some setae that aer between the individual facets of the compound eye
- Bugscope Teamthese help the wasp to sense wind movement
- Bugscope Teamthey are a lot shorter and stiffer than other setae on the wasp head to sense the wind better
- Guestmmhm
- Bugscope Teamwe are going to the mosquito now
- Bugscope Teamthis is a female mosquito
- Guestok
- Bugscope Teamthe donut shaped things in the middle of the head are the bases of where the antennae used to be, but they fell off
- Bugscope Teamthe eyes are actually the big compound eyes tht cover almost the entire head
- Bugscope Teamthe thing coming up in the middle holds all the mouthparts usually, it is like a sheath
- 2:24 pm
- Guestwoa
- Bugscope Teambut today we prepared this mosquito in a way so that the mouthparts are sticking out of the sheath
- Bugscope Teamso all the swirly stuff around the sheath are the mouthparts that are usually hidden
- Guesti have a random question...r u at Bekman institute?
Bugscope Teamyes we are located at beckman institute
- Bugscope Teamso this is a stylet, which is the part that cuts into your skin when it bites you
- Bugscope Teamit acts like a steak knife
- Bugscope Teamand now you can see a second stylet
- Guestwhats that?
Bugscope Teamthis is another stylet uses to cut into your skin so that the siphon which we are about to go to , can get to the blood
- Bugscope Teamthe siphon is here now
- Bugscope Teamthis is like a hypodermic needle that sucks up the blood, and it can also put its saliva in so that it can thin your blood
- Guestow!
- Bugscope Teamit is very sharp, not as sharp as the stylets, but still very sharp
- Bugscope Teamnow we moved to a leafcutter ant
- Bugscope Teamwe have 2 today, this is a smaller one
- Bugscope Teamwe will probably move to the bigger one in a minute
- Bugscope Teamyou can see it has a small compound eye compared to the wasp and the mosquito
- 2:29 pm
- Bugscope Teamthats because it doesnt rely on its eyes so much as it relies on its antennae
- 2:39 pm
- Guestwell i g2g
