- Bugscope Team sample is pumping down...
- Bugscope Team Good Morning, Jones. welcome to Bugscope!
- Bugscope Team hi miss sands' class
- Guest hello!
- Bugscope Team we are setting up presets right now
- Teacher Mrs. Fleury's class is here !
- Teacher Mrs. Wipper's class is here!
- Bugscope Team i are just going to grab a couple more presets quickly
- Guest Mrs. Gleva's class is here!
- Bugscope Team you have control Mrs. Fleury
- Bugscope Team we can give control to someone else if you like
- Bugscope Team we are ready to roll!
- Teacher We are going to look at the pillbug first aka rolliepollie
- Bugscope Team this is a roly poly, or pillbug
- Bugscope Team they are actually crustaceans
- Bugscope Team that live on the land
- Bugscope Team they are also called isopods because all of their little feet are the same shape. iso- means 'the same.'
- Bugscope Team and pod means 'foot'
- Bugscope Team these are little spines on the rolypoly's leg
- Bugscope Team spines like this are often sensory; they help the pillbug sense its surroundings when they are touched. they might also be used for self-sending, so the pillbug can tell when its little leg is extended, for example
- Bugscope Team please be sure to let us know when you have questions
- Guest why is it called a pill bug?
Bugscope Team they are called pill bugs because they roll up into a little ball, or pill, when they feel threatened
- Bugscope Team this is the pill bug
- Bugscope Team 's mouth!
- Bugscope Team at the top we can see its mandibles, or jaws, which open left and right, not like our jaws
- Teacher What do pill bugs eat?
Bugscope Team I believe they eat decaying plant matter
- Bugscope Team yes they eat decaying plant matter, decaying animal matter, and sometimes live plants
- Guest Do they have eyes?
Bugscope Team yes they do. they are small and a bit hard to find from beneath like this
- Teacher Does anyone else want to see another part of the pill bug or are you ready to move on?
- Bugscope Team they have seven pairs of legs
- Teacher ready to move on
- Guest How big do they get?
Bugscope Team we have seen them only about a centimeter long; the kind that live in the oceans can get quite large
- Bugscope Team this onw is a few centimeters big
- Bugscope Team one*
- Bugscope Team the ocean ones get to be a like a basketball, i think
- Bugscope Team their exoskeletons are made of chitin, which is similar to the keratin in our fingernails.
- Guest How hard are their shells?
Bugscope Team I think kind of like a fingernail, but thinner and thus a bit softer
- Guest We wanted to know what animals eat pillbugs
Bugscope Team I looked it up, and where I looked said "vertebrates and invertebrates," not very helpful
Bugscope Team they are probably snacks for mice and rats and other small animals
- Bugscope Team this is a wasp, and toward the bottom of the screen we can see one of its antenna combs
- Bugscope Team that is, the forelimb is shaped so that it will fit over an antenna and scrape it (gently) clean
- Bugscope Team right in the middle now
- Bugscope Team looks like a spike coming out of its arm , and there is a curved part of the arm just above it
- Bugscope Team on the back of the wasp's head, to the right, we see little bumps that are the ocelli -- the simple eyes
- Bugscope Team its antennae bend toward the left and down
- Bugscope Team the wasp is lying a doublestick carbon tape
- Bugscope Team 'on' doublestick carbon tape
- Bugscope Team now we see the compound eye, which has a few thousand ommatidia, or individual facets
- Teacher What are simple eyes vs compound eyes?
Bugscope Team compound eyes have many facets like you see here. simple eyes don't see as well, and you find them on larvae or spiders
- Guest How long can a wasp live?
Bugscope Team usually a few months
- Guest Hello! We're wondering how far a wasp flies away from his nest?
Bugscope Team they can fly from 300-1000 yards from their nest
Bugscope Team which is half a mile
- Guest What do they eat?
Bugscope Team some of them like sticky, sweet stuff, like fruit; some like nectar from flowers; and some also eat decaying flesh from dead animals
- Bugscope Team this is one of the ocelli, in front; we can see the other two, but not as well
- Guest Do they have hair?
Bugscope Team the things that look like hair we are supposed to call 'setae,' but even the entomologists often call them hair.
Bugscope Team the setae are often sensory. different ones can sense touch, wind, chemical odors, hot/cold
- Guest Where is this wasp from?
Bugscope Team I am not sure; Cate may know.
- Guest Can we see the stinger?
Bugscope Team yes there is a preset for the stinger of one of the wasps today
- Guest What do they use their claws for?
Bugscope Team they use their claws in much the same way we use our hands, except I guess they don't type or write much; but they can grasp things and climb, for example
- Guest How many eggs can a wasp typically lay?
Bugscope Team it really varies. many species of small wasps are parasitic wasps, and they lay one or more eggs inside insects they have stung and paralyzed
- Guest Do they have ears?
Bugscope Team not like we do. there are some that have an organ that can result in hearing.
- Teacher When a wasp stings you, does it lose it's stinger?
Bugscope Team no; they can often sting repeatedly. when a honeybee stings you and loses its stinger, it is because your skin (mammalian skin) is thick, and the barbs on the stinger get caught in it
Bugscope Team that is, honeybees can sting other insects repeatedly, but when they sting mammals they lose their stingers, and they die then because the stinger fell out and they will thus bleed to death
- Bugscope Team stingers sometimes have two sharp parts that slide, side by side, to cut into their prey
- Bugscope Team stingers are also used as ovipositors in some species of insects, like wasps. an ovipositor is an egg-depositor
- Guest What kind of a spider is this?
Bugscope Team It is so tiny; I don't think we know. It is a baby flat spider.
- Bugscope Team we aren't very good at identifying spiders, unless they have those telltale markings, like black widow and brown recluse
- Bugscope Team we can see from the scalebar that the spider is only a few millimeters long
- Bugscope Team its abdomen is to the right, and usually at its terminal end we see the spinnerettes, but not today
- Guest What is the large, round part on the back?
Bugscope Team that is called the abdomen; it is soft compared to the head and thorax, which are fused into what is called a cephalothorax
- Bugscope Team here we can see the eyes
- Bugscope Team now we see two palps, or pedipalps; this seems to be a female, with small palps
- Guest Where does the word spider come from?
Bugscope Team that is a very good question!
Bugscope Team it comes from the old english version of spin
- Bugscope Team if spiders get hungry, they can eat their web, which is made of protein, to help them live a little longer
- Guest do spiders eat insects or just drink their blood?
Bugscope Team they inject their venom, which dissolves the insects' internal organs, and then they suck it all up like a milkshake. so it is not all just the blood, which is called hemolymph
- Bugscope Team this is the head of a moth
- Bugscope Team it has lost its antennae, but in the front of its head we can see its proboscis, which is still coiled up
- Guest How much web can a spider have inside?
Bugscope Team it comes to a certain percentage of the size of the abdomen, but I am not really sure
Bugscope Team one answer is that the spider has at least enough web inside it to make a web at least twenty times its size
- Bugscope Team the proboscis is like a long straw
- Guest What are the things that look like hair?
Bugscope Team many of those are scales, which are actually modified setae, what we think looks like hair
Bugscope Team one thing the scales do (we see them most commonly on butterfly and moth wings) is protect the insect that bears them from getting caught in a spider's web
- Guest What kinds of animals eat moths?
Bugscope Team flying animals like bats, and ground animals like rats and mice
- Teacher Is that the moth's mouth right behind the proboscis?
Bugscope Team I think we can say that it is, but the moth usually sucks its food up as a liquid, through the proboscis
- Bugscope Team spiders and birds also eat moths
- Teacher What is on the moth's eyes?
Bugscope Team they are some loose scales
- Guest What do moths eat?
Bugscope Team most adult moths do not eat at all, but some of them drink nectar, like that from flowers
- Teacher Do moths shed their skin?
Bugscope Team once they become adults and have wings, that is it; they do not molt after that
- Teacher Do they follow the same lifecycle as a butterfly?
Bugscope Team yes they have caterpillars and cocoon stages before they are adults
- Guest Do moths have strong wings?
Bugscope Team we would say that it varies, because there are many types of moths, but yes I think in general they have strong wings
- Bugscope Team very recently, someone showed that moths, when they take off from a sitting or standing position, use their legs to propel them forward before moving their wings.
Bugscope Team so they jump to help them get started flying
- Guest How do they breathe?
Bugscope Team there are spiracles along their body that look like portholes. these spiracles are connected to a trachea that runs through their body
- Bugscope Team insects can open and close their spiracles
- Bugscope Team a majority of the female ants are wingless
- Guest What color is ant's blood?
Bugscope Team usually the entomologists tell us that it is clear, or colorless. when you squish an insect you often see what looks like yellow fluid, but that is the blood plus the contents of their abdomen, for example
Bugscope Team the blood is called hemolymph
- Bugscope Team most ants you come across are female
- Guest Do ants have good eye sight?
- Guest How can you tell the difference between female and male ants?
Bugscope Team yes when you find ants with wings, those are often males, unless you have found a queen ant, which can have wings for a while
Bugscope Team the males will have wings, and apprently, their antennae are longer
Bugscope Team apparently*
Bugscope Team their antennae have chemoreceptors that help them find the queen ant while they are flying
Bugscope Team chemoreceptors can sense smells in the air -- such smells as pheromones, which for example females may produce, like perfume, to attract males
- Teacher What is the lifecycle of an ant?
- Teacher Why is it itchy after we receive an ant bite?
Bugscope Team ants may sting more than they bite, and some of them will produce formic acid, which feels like a tiny burn
Bugscope Team I think the itching comes from your body's response to the bite or sting. Like a histamine response
Bugscope Team histamines are part of what your body produces in the immune response to a bite or scratch or sting, or sometimes something you ate
- Bugscope Team this is a surprise -- finding the tiny mites living on the wasp
Bugscope Team we have never seen mites like this before --- not that I remember
- Guest what is a mite?
Bugscope Team mites are tiny 'bugs' that are often arachnids of some sort, like related to spiders
Bugscope Team this actually appears to have only six legs, but juvenile mites, like juvenile ticks, may have six legs\
- Guest Thank you for answering our questions! We learned a lot!
- Teacher Why would a mite live on another bug? How big is this mite?
Bugscope Team we can see that is it about 200 microns, or micrometers, long. that is two tenths of a millimeter
Bugscope Team we find that in the insect/arthropod world there is always at least one species that will take advantage of any chance to profit, by eating and breeding at the expense of something else
- Guest Thanks so much from our class! We really enjoyed this!
- Bugscope Team Thank you, Everyone!
- Bugscope Team thank you for your great questions
- Teacher We appreciate this opportunity! Thank you for helping us learn more about insects today.
- Bugscope Team When we talk with the parasitoid wasp people, they tell us that there is not only a parasitic wasp for each insect, but a parasitic wasp for each life stage of each insect
- Bugscope Team See you next year!
- Bugscope Team Thank you!
