- Bugscope Team sample is in 'scope and pumped down
- Bugscope Team we'll start making presets for today's session in a few minutes
- Bugscope Team good morning, Amouton!
- Bugscope Team yay!
- Bugscope Team hi ms davis!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team Ms Davis you have control of the microscope; we are ready to roll.
- Bugscope Team this is the head of a small cricket you sent
- Bugscope Team one of its compound eyes deflated...
- Bugscope Team please let us know whenever you have questions, about anything
- Bugscope Team except maybe when the government will be back online
- Bugscope Team actually I was wrong about the eye deflating -- it is still there but the right antenna, on the left, is missing
- Guest Just wondering, is there any audio with the presentations? This is our first time, visiting bugscope.
Bugscope Team we don't do audio -- I don't think it would work very well
Bugscope Team we think it's better if our participants can type and ask us questions, and we can answer in the same manner; otherwise we wouldn't know if we were being heard, etc. We actually think this is a better way of teaching, as inquiry based learning. also fewer logistics.
- Bugscope Team Mitch and Shane we put a certain burden on the teacher and the students to control the 'scope, ask us questions, etc. This session is only just starting...
- Guest Thanks so much. Just wanted to make sure I wasn't missing anything.
Bugscope Team we are happy to have you on board
- Bugscope Team our participants can control the microscope directly and also, as part of that, select from any of the presets, on the lefthand screen
- Bugscope Team one person can control at a time
- Bugscope Team the participating school can use a variety of setups, from a single teacher with a computer to a roomful of connected computers with students to smartboards to projection screens
- Bugscope Team Mitch and Shane we just gave you control, if you would like, since Ms Davis dropped off, briefly
- Guest thanks
- Bugscope Team this is a scary bat-like beetle with fearsome mandibles like a spider
- Bugscope Team not sure what it is
- Bugscope Team the mandibles resemble spider fangs
- Bugscope Team the setae or bristles we see are mostly for sensory purposes
- Bugscope Team since insects do not have skin with nerve endings in it
- Bugscope Team insects have exoskeletons, which are like a suit of armor
- Bugscope Team so the sensory setae stick through that armor
- Bugscope Team setae can be mechanosensory, chemosensory, thermosensory, used for proprioception (mechanosensory as well)
- Guest What is on this area? Is it a piece of left over food or grass?
Bugscope Team it looks like some plant material and maybe some dirt too
- Bugscope Team you can see some dried fluid
- Bugscope Team spiders have poison or venom pores at the tips of their fang/mandibles
- Bugscope Team we often see a lot of dirt and mold
- Guest Is that what this could be on those hair like areas?
Bugscope Team mostly dirt and dried fluids here, looks like
- Bugscope Team when we see mold/fungus we see spores and also fungal hyphae, sometimes fruiting bodies
- Bugscope Team there may be some mold spores to the upper right
- Bugscope Team doesn't look very good, but that is a slightly shrunken mold spore
- Bugscope Team it's easy for insects to get mold on them. we almost always can see some on any insect
- Guest can we put a picture of the broken limb up?
- Guest Thank you. This is cool. :-)
- Bugscope Team this is a trachea
- Teacher Ok, we are all here now!
Bugscope Team great! I am giving you control of the 'scope!
- Bugscope Team Ms Davis you can click on any of the presets to get the 'scope to go where you'd like, and let us know if you have any trouble with that
- Teacher What are we looking at right now?
- Guest Thank you this is wonderful. You all are great!
Bugscope Team Thank you, Mitch and Shane
- Bugscope Team this is a higher magnification view of a trachea, which delivers oxygen to the inner organs
- Bugscope Team insects breathe through pores called spiracles, and the spiracles deliver air throughout the body
- Bugscope Team this is kind of creepy
- Bugscope Team it's the face of a very mean-looking beetle, not sure what kind it is
- Bugscope Team we're looking at the mandibles, which look just like spider fangs
- Teacher Good time to do this...close to Halloween!
Bugscope Team yeah!
- Bugscope Team this is the head of a cricket you sent us
- Bugscope Team the dome on the upper left is one of the compound eyes
- Bugscope Team we're looking at its face now, and its multiple mouthparts
- Bugscope Team i actually think this cricket is from another school.
- Bugscope Team many insects have two sets of palps that help them both taste and manipulate their food
- Bugscope Team we can see those palps, which look like extra arms and legs but smaller
- Bugscope Team and we can also see mandibles -- insect mouths are very complicated
- Teacher Cole wants to know if a compound eye closes like our eyes do?
Bugscope Team nope. insects dont have eyelids. they can use their antennae to wipe any dirt off their eyes
Bugscope Team not their antennae sorry. they use their front legs.
- Bugscope Team here we can see that this ant's mandibles are serrated like pinking shears
- Teacher we are surprised they are so "hairy"
Bugscope Team the hairs serve many purposes
- Bugscope Team insects do not have skin; instead they have a shell, called an exoskeleton
- Bugscope Team the hairs, which we are supposed to call 'setae,' help insects smell, taste, and feel hot and cold as well as touch
- Bugscope Team some of the hairs are extra small and they're called microsetae
- Bugscope Team scary
- Bugscope Team looks like a bat
- Bugscope Team microsetae are not sensory, as far as we know; they do help form patterns that other insects recognize, and they likely also help with thermoregulation, like fur
- Bugscope Team the big flat things we see in the lower part of this image are palps
- Teacher like what?
Bugscope Team setae are called mechanosensory -- for sensing wind and touch and also helping the insect feel if its limbs might be hyperextended
Bugscope Team some setae are chemosensory and help the insect smell chemicals in the air as well as tasting what might be food
Bugscope Team some setae are thermosensory -- for sensing hot and col
Bugscope Team oops cold
- Bugscope Team this is pretty cool
- Bugscope Team you can see that the mites are about 100 micrometers long, which is one tenth of a millimeter
- Teacher So this insect has different insects on it?
Bugscope Team yes! the mites are more related to spiders, so they are not really insects
- Bugscope Team we often find them on earwigs like this, hidden where the earwig cannot reach them and scrape them off
- Bugscope Team micrometers are also called microns
- Teacher Why are the mites on the earwig?
Bugscope Team we are not sure what they do there -- for example we are not sure if they feed on body fluids from the joints or if they eat food droppings the earwig misses
- Bugscope Team many insects and arthropods seem to have a kind of defense against mites accumulating on them
- Bugscope Team we do not see mites on pillbugs, or not very often, for example
- Bugscope Team this is the praying mantis's head, and we can see that one of its eyes collapsed and shrank a bit after it died
- Bugscope Team its mouth also has some goop on it
- Bugscope Team we can see that this praying mantis's head is more than two millimeters wide
- Teacher Is that the antenna at the top of the head?
Bugscope Team yes!
Bugscope Team yep they are those sticks
- Bugscope Team praying mantises are said to have a single 'ear' on the thorax -- the chest area. but we do not know just what it looks like
- Bugscope Team bye Mitch and Shane!
- Guest Thank you for your time. We have to leave. This was amazing!
Bugscope Team Thank you for connecting with us this morning!
- Bugscope Team this is a moth, and we can see that its proboscis is coiled and bent a bit off to one side
- Teacher What do the antenna do for the insects?
Bugscope Team they are like the ears and mouths in the insect world. They sense chemical signals from others of their species
- Bugscope Team often, when you see a moth -- without magnification, even -- you can tell the males from the females because the males have much fancier antennae
- Teacher interesting!
- Bugscope Team the female moths produce pheromones, which are chemicals they release into the air like perfume, that attract the males
- Bugscope Team the male moths have those ornate antennae to help them sense very small amounts of pheromone in the air
- Bugscope Team mosquitoes are like that too -- the males, which do not bite, have fancier antennae
- Teacher We are going to have to sign off! It is lunchtime here! We really enjoyed our session, Thanks!!
- Bugscope Team Thank You!
- Bugscope Team See you next year!
- Bugscope Team thanks Ms. Davis for joining us today
- Bugscope Team Bye, Everyone!
