• 1:21 pm
• Bugscope TeamHi Shannon.
• Bugscope Teamsorry that didn't sound very welcoming -- Hi Shannon!
• Bugscope Teamwelcome to Bugscope!
• Bugscope Teamwe're waiting for the microscope to pump down; then we'll turn on the electron beam and start imaging
• 1:30 pm

• TeacherHi! This is Tami French at Valeska Hinton
• Bugscope Teamhi! we are just working on presets now
• TeacherAm I seeing one of our ladybugs?
• Bugscope Teamonce we are done with presets you can take control of the microscope and practice driving
• Bugscope Teamthis is a cranefly. we included some of our insects along with the beetles you sent
• TeacherWe're not due to start until 1:45 - the children are not back from Music yet - I just wanted to make sure I could get on
• Bugscope Teamsure no problem!

• 1:36 pm

• TeacherBoth classes are here and ready to learn!

• Bugscope Teamjust give us a few more minutes and we will get your insects and a couple of ours

• 1:42 pm
• Teacherok

• Bugscope Teamhere is one of your ladybugs

• TeacherNyLah wants to know: Do ladybugs live all over the world?

• TeacherAre we seeing hair?
• Bugscope Teamthey are found in temperate regions like ours around the world.
• TeacherMouth parts?
• Bugscope Teamthey may vary in color from yellow to red
• Bugscope Teamthat's right!

• TeacherCompound eye?
• 1:47 pm
• Bugscope Teamyes compound eyes are made of many facets, like a diamond
• Bugscope Teamthey see many parts of an image
• TeacherWe have goggles that replicate the effect.
• Bugscope Teamthe facets also help the insect to see movement much faster than we do
• Bugscope Teamcool!
• Bugscope Teamdo you have them on now now now?
• Bugscope Teamthe things that look like vacuum nozzles are palps, which help the ladybug to taste or move around food
• Bugscope Teamthere are little 'taste buds' within the palps for taste/smell
• Bugscope Teamthere are mandibular and maxillary palps, named after the jaws
• Bugscope Teamwhat is cool about some insect eyes is they can see colors we can't, like ultraviolet
• Bugscope Teamin people, the lower jaw is the mandible and the upper jaw is the maxillary
• Bugscope Teamscanning electron microscope (SEM)
• TeacherVery cool.
• TeacherCan a ladybug move its head?
• Bugscope Teamlooks like it is difficult, doesn't it?
• Bugscope Teamit can't move very much, it can go inward like a turtle a think
• TeacherThe kids want to know what ladybugs eat?
• Bugscope Teamthey can; sometimes we see them with their heads shifted a bit
• Bugscope Teamthey eat other insects
• 1:52 pm
• Bugscope Teamthey find aphids especially delectable
• Bugscope Teamaphids are soft-bodied
• TeacherWhen do the adult ladybugs lay their eggs?
• Bugscope Teamladybugs are good to have around

• Bugscope Teamthey live as adults from about 4 to 6 weeks, although we know some of them overwinter
• TeacherWe want to know what the round white thing is
• Bugscope Teamladybugs mate in the spring, so the eggs would come shortly after that
• Bugscope Teamthis thing?
• TeacherYes, that thing
• Bugscope Teamthis is one of the other kinds of palps
• Bugscope Teamthe little bumps are special sensory hairs for picking up smells and tastes
• Bugscope Teamlike tastebuds
• TeacherWhat does it do?
• Bugscope Teamit helps the insect taste its prospective food
• Bugscope Teamnow we can see the chemosensors
• TeacherWow
• Bugscope Teaminsects are very hairy
• 1:57 pm
• TeacherCan we see another part of the ladybug?
• Bugscope Teamthe 'hairs' are called setae
• Bugscope Teampronounced 'see-tee'

• Bugscope Teamthis is one of the claws
• TeacherWhat is that
• Bugscope Teamdo you know how many legs insects have?
• Bugscope Teamthere is a claw on each of the legs
• Bugscope Teamthey help to pick up things like our hands
• Bugscope Teamso this is one of the claws, and also, we can see that it has lots of sticky hairs called tenent setae running up the arm
• TeacherKids want to know if ladybugs have ears?
• Bugscope Teamwhen a ladybug walks on a ceiling, it uses those tenent setae to help it stick
• Bugscope Teamthey do not have ears like you would think
• Bugscope Teambut like other insects they can hear
• TeacherIs it more of a tympanum like a turtle has?
• Bugscope Teamsome of the setae we were talking about are sensitive to vibration, and sound is vibration
• Bugscope Teamsome insects have tympani as well
• TeacherOK
• Bugscope Teama praying mantis has one big 'ear' on its thorax
• TeacherCan ladybugs swim?
• Bugscope Teamthey cannot really swim
• Bugscope Teamno not really
• TeacherKids want to know if ladybugs have blood and what color it is
• Bugscope Teamthey can close their spiracles and hold their breath that way
• 2:03 pm
• Bugscope Teamthey have what is called 'hemolymph,' which is like blood, but it is usually clear
• TeacherDo all insects have wings?
• Bugscope Teamwhen we smash an insect and see yellow goo, it is hemolymph plus other liquids inside the insect
• Bugscope Teamno not all do
• Bugscope Teamfor instance, there are aphids that may or may not have wings
• Bugscope Teamnot all insects have wings, but once an insect becomes and adult, if it has wings, it will not grow anymore
• Teacher Kids would like to see another insect
• Bugscope Teamyes as Cate says, aphids are really interesting because when they start to run out of food where they are, the next generation of aphids will have wings

• Bugscope Teamdoes anyone recognize this?
• Bugscope Teamthey have tympani on their legs
• TeacherFly?
• TeacherAnt?
• Bugscope Teamsorry -- it is hard to tell...
• TeacherGrasshopper?
• Bugscope Teamthat's it!
• Bugscope Teamgrasshopper

• 2:08 pm
• TeacherCan you zoom in on antenna
• Bugscope Teamkind of Victorian looking with a high-shouldered overcoat
• TeacherWas the 'overcoat' the thorax
• Bugscope Teamwe do not have antennae, obviously, but to insects they are very important
• Bugscope Teamyes it was
• TeacherKids want to know about the holes on antenna
• Bugscope Teami think those are places where some hairs fell out
• Bugscope Teampores for the hairs
• Bugscope Teaminsects have hairs all over that are sensitive to different things, like sense of touch
• Bugscope Teamthey don't have soft sensitive skin like we do
• TeacherCan a ladybug move its legs sideways?
• 2:13 pm
• TeacherWhy do ladybugs have spots?
• Bugscope Teamthey can skitter sideways a little big, but not very well or very far
• TeacherHow long can a ladybug fly?
• Bugscope Teamthe spots are part of a warning system for other insects, along with their color. they emit a bad smell and taste bad when eaten
• Bugscope Teamoh look, the holes seem to have a special hair in them
• Bugscope Teammaybe the hairs help to sense chemical information
• TeacherWhat are we seeing now?
• Bugscope Teamladybugs can fly maybe around a 100 miles to find food
• Bugscope Teamwe are zoomed in on one of those holes on the antenna of the grasshopper
• TeacherDo all insects have a thorax?
• TeacherHow long do ladybugs live?
• Bugscope Teamyes. they are supposed to have 3 main body sections- head, thorax, and abdomen
• Bugscope Teamusually ladybugs can live around a month or 2, but sometimes the larvae can overwinter in our houses, so they could potentially live for much longer
• Bugscope Teamspiders don't really have a thorax, but they aren't really insects.
• Bugscope Teamspiders have a cephalothorax, which is like a head and thorax in one
• 2:19 pm
• TeacherHow far can a ladybug walk?
• TeacherHow long does it take an egg to hatch
• Bugscope Teamit takes around 3-5 days for the eggs are hatch
• TeacherKids want to see a flea
• Bugscope Teami'm not sure how far one can walk

• Bugscope Teamhere is a tick we had in our collection
• TeacherTicks are neither insect nor spider - they are?
• Bugscope Teamwhen we make a sample for Bugscope, we put whatever we have at the time on the stub.
• Bugscope Teamthey are more related to spiders than insects
• TeacherMekel wants to know what class ticks are in
• Bugscope Teamthey actually start out with six legs, and as they grow and molt and become adults they gain two more legs

• 2:25 pm
• Bugscope Teamthis is the top of the tick's head, but it is broken
• Bugscope Teamthis is one of its claws
• Bugscope Teamticks have little hooks that they use to balance themselves on top of leaves
• TeacherDo you have a bee to show us?
• Bugscope Teamthey stick their arms out, and when you walk by they catch hold of you with their arms; you lift them off of those hooks

• Bugscope Teamthis is one of the hooks that they clip over leaves
• Bugscope Teamticks are often covered with bacteria, although we have not see any yet today
• Bugscope Teamwhen they get swollen with blood, they can break open
• TeacherI live in the country and am too familiar with ticks!
• Bugscope Teamcool can you send us some? haha
• 2:30 pm
• Bugscope Teamthey can heal themselves when they break open
• TeacherAs many as you want!
• TeacherDog and cat bring them by the dozens!

• TeacherWhat is tha?
• Bugscope Teamthis is a cranefly
• TeacherDoes it have sucking mouth parts?
• Bugscope Teamthey look like industrial sized mosquitoes
• Bugscope TeamI think they do but it is hard to tell here
• TeacherDo they 'bite' like mosquitoes?
• Bugscope TeamCate looked it up for me -- they either feed on nectar, or they do not feed at all as adults
• Bugscope Teamthey are entirely friendly to humans
• Bugscope Teamsome insects, as adults, do not feed. male mosquitoes sometimes do not feed, but the females certainly make up for that
• Bugscope Teamhey look what we found!
• Teacherpollen
• Teacherpollen?
• Bugscope Teamthat's right!
• Teacheron a bee?
• 2:35 pm
• Bugscope Teamthis is the head of the cranefly
• Bugscope Teamit is very furry
• TeacherNo wonder it makes us sneeze
• Bugscope Teamthis is what turtles look like when they migrate en masse
• TeacherCompound eye?
• TeacherLOL
• Bugscope Teamyes it is!
• Bugscope Teamthe eye facets, called ommatidia, are a little shrunken since the cranefly died and started to dry up
• TeacherDo insects drink and what do they drink?
• Bugscope Teamsome of them drink nectar, from flowers
• Bugscope Teaminsects do need water
• Bugscope Teambut they get that from their food
• Bugscope Teamsome of them like salty perspiration
• TeacherKids were asking about spiracles. Can you show us?
• Bugscope Teamyes let's see if we can find some
• Bugscope Teamwe'll look on the grasshopper
• Bugscope Teamspiracles is how they breathe. they have ports on their sides that are connected to a long tube in their body, called a trachea
• Bugscope Teamthe trachea supplies the oxygen to the cells
• Bugscope Teamthere's a closed one...
• Bugscope Teamthey don't breathe through their mouth like we do
• 2:42 pm
• TeacherSo they open and close?
• Bugscope Teamsome can
• Bugscope Teamthis one is hard to see well
• Bugscope Teamit's how they can survive a little bit in water- like holding your breath
• Bugscope Teamit's next to the haltere
• TeacherDon't know haltere

• TeacherOn the compound eye, what are the individual 'mounds' called?
• Bugscope Teamthey are found only on flies. they beat opposite the wings and help balance the fly as it....flies
• Bugscope Teamommatidia
• Bugscope Teamfinally, on this housefly...
• Bugscope Teama spiracle!
• Bugscope Teamspiracles are connected to tubes called tracheae on inside of the body
• Bugscope Teamthey carry oxygen to internal organs
• TeacherHow many spiracles do they have?
• Bugscope Teamthey have two on each body segment, generally
• Bugscope Teamon either side
• Bugscope Teamthey depends on how big/long the bug is
• 2:47 pm
• Bugscope Teamand some are larger -- the thoracic spiracles on flying insects can be quite large
• Bugscope Teamsome insects will have clear segments, and you can see there is a spiracle on each side of the segment
• TeacherDo our ladybugs have mites?
• Bugscope Teamnot usually that we see
• Bugscope Teamwe have never seen mites on ladybugs, that I remember
• TeacherMostly bees have mites?
• Bugscope Teambees have varroa mites, but there are other kinds of mites that are smaller -- we see them most often on earwigs
• TeacherWe know they have exoskeletons. Do insects have muscles?
• Bugscope Teamcute little beetle
• TeacherFace only a mother could love!
• 2:52 pm
• Bugscope Teamtheir muscles are on the inside
• Bugscope Teamhere is one of the little beetle's arms
• TeacherVery hairy!
• Bugscope Teamit looks like this one cannot climb on glass
• Bugscope Teamalso it has one of those things that looks like a flying plant on it
• Bugscope Teamwe see these sometimes and don't know what they are
• TeacherWhere on the insect is it?
• Bugscope Teambeneath, or attached to the claw
• Bugscope Teamoops this is kind of sad
• Bugscope Teamdo you recognize this?
• 2:57 pm
• TeacherMy first graders have done a great job and asked lots of good questions. But they are at their limit for sitting still. Thank you very much for this session. It has been great. I think there are several entomologists among them. They are asking for the web address so they can look later. Have to sign off and get packed to go home. Thank you!!!!!!!
• Bugscope Teamvery patient first graders
