• 8:21 am
• Bugscope Teamsetting up...
• 8:44 am

• 8:50 am

• GuestHi! It's Mrs. Schaab. Can you please email me my password so I can log in as the teacher?
• Bugscope TeamGood morning!
• GuestGood Morning!

• Bugscope Teamwe are making presets; I gave you control and also sent your presumed password.

• 8:55 am

• Bugscope TeamMorning, Tony!
• TeacherPerfect! We are logged in.

• GuestJust like old times!

• Bugscope Teamthis is Scott; Cate is next to me, making presets
• GuestI'll be observing from afar and trying to stay out of the way.

• GuestHello Ms. Arsenault and Mrs. Schaab!
• Bugscope Teamwe have ordered a new scanning electron microscope

• TeacherWe are just getting settled in front of the SMARTBoard
• 9:00 am

• Bugscope Teamwe are ready to roll!
• Bugscope Teamplease let us know when you have questions!
• Bugscope Teamyou have control of the microscope
• 9:06 am
• Bugscope Teamthis is the head of a female housefly
• Bugscope Teamin the middle we can see her proboscis, which is kind of like a tongue
• Bugscope Teamher compound eyes are the lighter gray domes on either side of her head
• Bugscope Teamthere is also some lint on her head
• Teacherwe were just guessing what we were looking at
• TeacherSome guesses were grasshopper, rolly polly, and ant
• Bugscope Teamthe eyes of female houseflies are far apart, and the eyes of male houseflies are close together, sometimes almost touching

• Bugscope Teamthe tongue is spiny
• Teacherwhat are we zooming in on

• Bugscope Teamthat was the tongue of the fly, with little spikes on it
• Bugscope Teamnow we have a new insect to guess about
• TeacherWhy is the tongue spiny?
• 9:11 am
• Bugscope Teamthe tongue has little hairs on it, or spines, that can sense when it is touching something
• Bugscope Teambecause insects do not have skin, like we do (instead they have a shell, also called an exoskeleton), they have lots of tiny hairlike things that help them feel, taste, and smell the world
• Teachernow we are guessing, a dragon fly, a grasshopper, a regular fly, a bug that sucks blood, or a fly crab
• Bugscope Teamthe background is carbon tape that the insects stick to. it looks bubbly
• Bugscope Teamsome of those tiny hairs, which are called setae ('see-tee') can sense hot and cold; some sense wind, or touch; some can taste by touching things; and some can taste the air the same way we smell perfume.

• Bugscope TeamI don't think we have seen any flies, yet, that have mandibles; this insect has mandibles (jaws)
• Bugscope Teamthe mandibles are crossed in front of the mouth

• Bugscope Teamthe mandibles open left and right, like a gate
• Bugscope Teamthe jaws open out like a gate, unlike ours that move up and down
• Bugscope Teamthe hinges of the 'gate' are at the edges of the compound eyes
• 9:17 am

• TeacherWe are wondering why there are so many bumps on the eye

• Bugscope Teamthose are all ommatidia- the ones that are shaped like a honeycomb. the ommatidia are facets of the eye
• Bugscope Teamthere are smaller bumps that are dirt or dried liquids
• Bugscope Teaminsects that fly, especially, have to be able to see very well, and they often have eyes with many ommatidia, which help them sense motion very quickly -- much more quickly than people sense motion'

• TeacherCan you zoom all the way out so we can see the entire insect
• Teacherplease?
• Bugscope Teamthere are probably two to three thousand facets (ommatidia), and we can see that they wrap around the head

• Bugscope Teamwe cant see too far out. the microcope wont let us
• Bugscope Teamthis is about as far out as we can go
• Bugscope Teamouch

• 9:22 am
• Bugscope Teamwe are moving down the body of the insect

• TeacherOur guesses are grasshopper, wasp, spider, butterfly, & ladybug
• Bugscope Teamit has a narrow waist, and it can fly...
• Bugscope Teamone of those is correct!

• Bugscope Teamthis is like a tiny sword at the tip of its abdomen

• TeacherWe picked a flying ant next
• Teachersome questions we have are...
• TeacherDoes the flying ant larva start out with wings?
• Bugscope Teamno. the larva is like a worm
• 9:27 am
• Bugscope Teamit will have wings when it becomes an adult. much like how caterpillars dont have wings, but then they become butterflies
• TeacherThe class just got raising ladybugs
• TeacherThat's similar to ladybugs!
• Bugscope Teamthose are good for plants. they will eat the bad aphids that try to eat the plants
• Bugscope Teamand yes. the baby ladybugs are also kind of ugly
• Bugscope Teamin my opinion. maybe some of you think they are cute!
• TeacherWe agree with you!

• Bugscope Teammost ants you see are girls. same goes for bees. That is because they do the work for the colony or hive
• TeacherWe are curious, is the flying ant's mandible like a gate? Or is it like ours?
• Bugscope Teamit is like a gate
• TeacherWhy do some insects open like a gate? We chew our food up and down.
• 9:32 am
• Bugscope Teami don't think they really chew their food. They dont have teeth. Maybe this is the more direct way to shovel the food into their mouths
• Bugscope TeamThat is a good question

• Bugscope Teamwhen insects die, their insides dry up causing their legs to fold in, because their ligaments shorten and tighten
• TeacherHow many legs does the flying ant have? We think we see 6
• Bugscope Teamthat would be right! all insects have 6 legs. if it has more, than it is not an insect

• TeacherWhat are the things that look like eyes?
• 9:38 am
• TeacherThey aren't eyes, right?
• Bugscope Teamthese are special receptors that sense chemicals. it is a way of communicating with their antennae
• Bugscope Teamthey are not eyes
• Bugscope Teamthey are kind of like short, fat hairs
• TeacherJust like on ladybugs that helped them smell!
• Bugscope Teamyes!
• Teacher& helped them taste and touch!
• Bugscope Teamsimilar to tastebuds on our tongues. the long ones are more for feeling things
• TeacherDo the receptors help them hear?

• Bugscope Teamno. some insects will have an organ that would help them with that, but not many do. they rely more on their other senses, maybe even helping them feel vibrations
• TeacherOne of my friends is explaining to the class that a butterfly uses it's antenna to help figure out where to lay eggs. Does the wasp do the same?
• 9:43 am
• Bugscope Teamthey can help to feel how big the area needs to be to lay the eggs in, i believe. I am not a very good expert on that though
• TeacherCan we ask you some questions about your Job, Cate & Scott?

• Bugscope Teamyes sure. go ahead!
• TeacherWhat do you do everyday? We know you study insects... but what do you do every day?
• TeacherDoes an entomologist study only insects or bugs too?
• TeacherHow many different insects and bugs are there?
• Bugscope Teamwe don't always look at insects. We run a lab with various microscopes and help researchers image samples for their projects
• Bugscope Teamthere are so many insects, we still havent identified them all! entomologists may study some non-insects, like spiders, but not heavily.
• 9:48 am
• Bugscope Teamarthropologists would be the more general scientist that would study all the creepy crawlies
• Bugscope TeamWe see more than just insects. We see people that study plants, or very small particles, or bones
• TeacherDo all the species of grasshoppers have wings when they are adults?
• TeacherWhy do bees fly?
• Bugscope Teamyes. they have 2 pairs of wings
• TeacherHow do bees get their honey out?
• Bugscope Teambees fly so they can move around easily between their hive and the flowers they like
• TeacherAfter these, we need to go. We have really enjoyed chatting with you and looking at the different specimins!
• Bugscope Teambees make honey when they eat nectar and store it in a special honey stomach. they then spit it out and when it dries, it becomes honey
• 9:54 am
• Bugscope Teamthank you for joining us and asking such good questions
• TeacherWow! We are all learning something new about honey!
• Bugscope Teamsounds really gross, but it's so yummy
• TeacherThank you for teaching us about insects! We had so much fun!
• GuestOne can learn a lot in kindergarten!
• TeacherMs. A & Mrs. Schaab will see you tomorrow with our PM Kindergarten Entomologists!
• Bugscope Teamall right! can't wait.
• Bugscope Teamthanks for logging in! see you tomorrow
• 12:36 pm
• Bugscope Teamsettin up for Wednesday session!
• Bugscope Teamsetting...
• 12:52 pm

• 12:57 pm

• 1:03 pm

• 1:08 pm

• Bugscope Teamgood afternoon!
• TeacherWe are just getting set up on our end!
• TeacherHi!

• 1:14 pm

• Bugscope Teamwe are ready to roll!

• 1:20 pm
• TeacherWe are ready! We are going to talk about some characteristics that we see and make some guesses on what we are looking at.
• Bugscope Teamthis is a super tiny insect that feeds on both plants and animals and is called a thrips
• Bugscope Teamsee how small it is? you will have to check the scale bar
• Bugscope Teamwe can see that the thrips is perhaps a millimeter and a half long

• Bugscope Teamcan you guess what this is?
• TeacherWhere would we see a thrips?
• Bugscope Teamyou can see that it is also very small when you look at the scalebar on the lower left of the image
• Bugscope Teama thrips you might see on the underside of a leaf, but they are so tiny it would be hard to tell what it was
• TeacherWe notice about the insect
• Bugscope Teamthey look like tiny little commas, or apostrophes
• TeacherThat it has wings, a thorax, and an antenna

• 1:25 pm
• Bugscope Teamalso it has a head and an abdomen, and it has six legs, although that might be hard to tell from here
• TeacherCan you zoom in on this bug's head please?

• TeacherSInce it has six legs, a thorax, and an abdomen, we know it's an insect!
• Bugscope Teamit has bumpy little eyes
• Bugscope Teamthat's right!
• Bugscope Teamplus it has two antennae
• TeacherWhat are the pointy things on the eyes? Bumps on the eyes?

• TeacherOur eyes are smooth, not bumpy! And they are farther apart than ours!
• Bugscope Teamthe insect might prefer that you not ask about those

• TeacherNow what are we looking at?
• Bugscope Teamthis is one of those pointy things, up close\

• TeacherWhy is that one bigger than all of the other ones?
• Bugscope TeamI am sorry -- we do not know just what that is
• TeacherWe think this might be a grass hopper, a praying mantis, a bee, or a fly?
• Bugscope Teamoh it is called an ocular tubercle, on the compound eye

• 1:30 pm
• Bugscope Teamit is an aphid- they are pests to plants and ladybugs love eating them
• TeacherCan we zoom out all of the way!
• TeacherWe know aphids from our ladybugs!

• TeacherWhat color are they?
• Bugscope Teamladybug larvae like to snack on aphids as well
• Bugscope Teamyellow or green
• Bugscope Teamthey like to blend in with the leaf color
• Bugscope Teamsometimes they appear to be black
• Bugscope Teamthey do not always have wings
• Bugscope Teamwhenever we see an insect with wings, we know it is an adult
• Bugscope Teamif a population of aphids are getting stressed from not having enough food nearby, the next generation will have wings. it's a sort of stress response

• 1:35 pm

• Bugscope Teamdo you know what this is?
• TeacherWe just had ladybug larva in our classroom!
• Bugscope Teamit does not have compound eyes
• Bugscope Teamits eyes are little bumps on the head near the antennae, which are also quite small

• Bugscope Teamladybug larvae like to eat those aphids you just saw
• Bugscope Teamthe eyes of the ladybug larva are called stemmata
• TeacherCan you zoom in on the mouth, please?
• Bugscope Teamthe pointy things that look kind of like fangs are accessory mouthparts called palps

• TeacherCan you explain what an accessory mouthpart is?
• Teacher& What are we zoomed in on now?
• Bugscope Teamthey are like little feelers that help the insect taste and also move its food around so it can be more easily eaten
• Bugscope Teamthis is the mouth of the ladybug larva
• 1:41 pm

• Bugscope Teamat the top we see a cleft that is the tip of one of the mandibles, which are the jaws
• TeacherSo the palps is like our tounge?
• Bugscope Teamthe jaws open left and right like a gate, and there is another piece on the top that goes up and down like a garage door while the insect eats
• Bugscope Teampalps are like tongues and eating utensils in one

• Bugscope Teamthe palps have little bumpy tips that are kind of like tastebuds on your tongue

• Bugscope Teamthis is one of the four palps
• Bugscope Teamat its end we see the tiny tastebuds

• Bugscope Teamhere are the tastebuds at the tip of one of the palps

• Bugscope Teamwe can tell that this might not be an insect
• 1:46 pm
• Bugscope Teamwhat is one of the clues that this is not an insect?
• TeacherIt looks like it has MORE than six legs
• Bugscope Teamyay!
• Bugscope Teamthis is a roly poly. it is a crustacean like a lobster or a crab

• Bugscope Teamit looks like some of the legs are missing
• Bugscope Teamif they have seven pairs of legs, how many would that be?
• TeacherWe are discussing. Give us a minute. :)
• Bugscope Teamrolypolies are also called 'isopods'
• Bugscope Team'iso' means 'the same,' as in an isoceles triangle
• Bugscope Teamand 'pod' means 'foot'
• GuestHello again! I will be watching from another location again.
• 1:51 pm
• Bugscope TeamHi Dr. Clishem!
• Bugscope Teamso if we call a rolypoly an isopod, we are saying that because when we look at its feet, all _ of them, they appear to be all the same shape
• GuestLet me slip in a comment and a question before the kids get started . . . First the comment . . . I always enjoy seeing your upgrades to your system. Really great! When will you interface to 3D printing?
• GuestNow my question . . . Any memorable "finds" this past year in your viewing experiences with classrooms?
• Bugscope Teamwe had 3D printers for many years, but not any more
• Bugscope Teamwe had one before they had those cute retail ones
• TeacherIf they have seven pairs of legs that means that they have 14 legs!
• Bugscope Teamthe coolest things for us in Bugscope have been finding mites on some insects
• GuestAnd I was kidding about the 3D printing . . . well, then, what's new on the horizon . . . It seems you are always pushing the envelope.
• Bugscope Teamwe used to have the kind of 3D printer that printed in white plastic, and then for many years we had the kind that print from powder into any color but black (the opposite of Henry Ford and the Model A)

• TeacherWe think this looks hairy!
• 1:56 pm
• Teacher& does it really have red eyes?
• Bugscope TeamDr T the future for us in this realm (we can do 3D xray imaging...) is a brand-new scanning electron microscope, in a few months now
• Bugscope Teamit's a moth, and the furry bits are the scales
• Bugscope Teamwhen you touch a moth or butterfly, the powder that comes off on your hands are the scales
• TeacherHow many different types of moths are there?
• Bugscope Teamthe insect looks hairy because it is covered with tiny scales
• TeacherWhere do we see red eye moths?
• Bugscope Teamthe scales are kind of like feathers

• TeacherCan we zoom in on them?
• TeacherAre they reptiles since they have scales?
• Bugscope Teamum. I am afraid they are not the kind of moths you would like to see, because they eat wool

• Bugscope Teamthey are scales that are more like the feathers of a bird.

• Bugscope Teamyes as Cate says, they are flakey, loose scales, kind of like potato chips but softer

• TeacherWe see a compound eye!
• Bugscope Teamlet's see if we can look at the scale that is lying on the compound eye

• Bugscope Teamvery good!

• TeacherWe only have a few minutes left

• TeacherCan we ask you about being an entomologist?

• TeacherOur choices today are awesome!
• Bugscope Teamyes you can
• 2:02 pm
• TeacherHow can you tell a boy ladybug from a girl ladybug?
• Bugscope TeamCate and I are electron microscopists, and as for being entomologists, we are amateurs
• Bugscope TeamI don't believe there is an easy way to tell the difference between male and female ladybugs from the outside.
• Bugscope Teamfemales are usually larger than males, but other than that they are very hard to tell apart
• TeacherDo you know how many types of butterflies there are?
• TeacherWhy are ants not colorful?
• Bugscope Teamthere are around 20,000 species of butterflies, with estimates of 130,000 species of moths
• TeacherHow many different types of bugs have you learned about/worked with?
• TeacherHow do bugs get their food?
• TeacherWhich bug has the most legs?
• Bugscope Teamwith ants it is likely not really an advantage to ahve specific bright colors; one reason is that they perform almost all of their communication using chemical signals
• Bugscope Teammost legs would likely be a millipede
• Bugscope Teambugs eat whatever is edible; there are different bugs for different things to eat, and some bugs, like roaches, can eat almmost anything
• Bugscope Teami have worked with hundreds of species of parasitic wasps, which are wasps that lay their eggs in other insects. However, for the most part, we see the usual varieties of insects like monarchs, houseflies, house spiders, etc
• 2:07 pm
• TeacherWe need to run to music. Thank you for the informative session this afternoon!
• TeacherThank you so much for working with us! We had some amazing conversation here!
• Bugscope Teamthat's right! Cate worked with someone who brought in about 360 species of previously un-named parastitic wasps
• Bugscope TeamThank You!
• Bugscope TeamSee you next year!
• TeacherLucky, Cate!
• TeacherYes, please! Thank you!
