- Bugscope Team we are just about ready!
- Bugscope Team good afternoon!
- Teacher Hi. OUr scout troop is gathering and connecting our devices.
- Bugscope Team we are ready to roll
- Teacher Hi Scot. This is Girl Scout Troop 831. We are in Va Beach, VA. The girls that are with us are in 2nd-4th grade.
- Bugscope Team Super cool!
- Bugscope Team you are welcome to start anytime.
- Bugscope Team You have control of the microscope, and with your permission I can hand control over to anyone you choose.
- Teacher Okay great, I have not done this in a couple years.
- Teacher Hi i am Mia
- Bugscope Team you may go to the lefthand screen and click on any of the presets there.
- Bugscope Team the microscope will drive to the place shown in the preset
- Bugscope Team Cool!
- Student Test message
- Bugscope Team our software is a little funky right now, and you have better control than I do.
- Bugscope Team test message worked!
- Student I am Summer and I am Maria
- Bugscope Team this is the top of the head of the fly
- Teacher What is the ocelli?
- Bugscope Team we are looking between the two compound eyes and can see at least two ocelli, which are simple eyes
- Bugscope Team ocelli -- the simple eyes -- do not see well but register dark and light and help the fly stay oriented with the sun
- Teacher What are the antennae looking things between the eyes?
Bugscope Team those are really small, actually, I know it is hard to tell -- they are bristles on the top of the fly's head that sense touch and wind, likely
- Student Hi I am excited my name is savanah nice to meet you
Bugscope Team Sweet! Nice to meet you!
- Bugscope Team insects and comparable arthropods do not have skin, as we know -- they have no bones, either. instead they have an exoskeleton, which is kind of like a suit of armor.
- Teacher Maria wants to known if insects have blood?
Bugscope Team they have something like blood that is called hemolymph
- Student Cool
- Student I am Summer and do bugs change color after they die
Bugscope Team sometimes they do
Bugscope Team usually they just get a bit duller in color
- Student Like a gray or yellow
- Bugscope Team colors in insects can come from both pigments, as we would expect, and the shapes of fine features. the latter are called structural colors.
- Teacher How do we zoom in on the microscope?
Bugscope Team at the top of the screen you should see controls for magnification, focus, contrast, and brightness
Bugscope Team that would be only the teacher (you), unless we give control to someone else
- Teacher Do the things on the front of the ant head bite things?
Bugscope Team yes they do! those are the mandibles, and that is a trapjaw ant that I believe feeds on collembola -- springtails
- Student Maria,"do bugs twitch after they die?"
Bugscope Team yes for a brief time, but not always; also, what happens is that the tendons inside their limbs tighten up, and we see that when they die and fold their arms and legs neatly
- Student Do you have a picture of a horse fly
Bugscope Team these are live images from the scanning electron microscope, and I am sorry -- we do not have any horseflies in the microscope today. it would have been so cool!
- Student Do you show in color
Bugscope Team there is no color because we are beaming electrons at the insects, and the electron beam is only 2.1 nanometers in diameter. just the wavelengths of color -- of visible light -- are 400 to 700 nanometers in diameters. in other words, we are imaging with a probe that is much thinner than light.
- Teacher I am having trouble moving any of the images, but I think we are okay. We are showing in grayscale.
Bugscope Team please let me help move the 'scope for you.
- Student Thank you for answering our QUESTIONS !!!!!!!!!!!!!!!!!
Bugscope Team yay! absolutely!
- Teacher Sure, if you want to just move it for us that would be great. :)
- Student Maria,that color is not shown makes sense
- Bugscope Team now we can see the compound eye of the trapjaw ant
- Teacher Are you an entomologist?
Bugscope Team no but I have been doing this since the beginning. our anniversary, of the first official Bugscope session, is March 19, 1999.
Bugscope Team Hey guys! I am an entomologist, I have been studying insects for about 4 years but have been an insect enthusiast since I was 5.
- Teacher What is a compound eye?
Bugscope Team a compound eye has a number of facets, or lenses, called ommatidia, that each collect an iamge
Bugscope Team sorry 'image'
- Bugscope Team we can see that the left antenna is broken off
- Bugscope Team plus Josh is an ant specialist, to the bigtime
Bugscope Team I dunno about big time ;) but officially yes.
Bugscope Team Scientists who study ants are known as myrmecologists.
- Student Hi josh
Bugscope Team sup!
- Bugscope Team this is a surprise, super tiny beetle on the stub
- Student Mia, Can ants be different colors like Brown?
Bugscope Team ants come in many different colors: black, brown, red, orange, green; there are some that are even a metallic gold color
- Bugscope Team we can see that this beetle is just less than 2 mm long
- Student Is it a Bee
Bugscope Team its a bee...tle! beetle :)
- Student Mia "that is awesome "
- Student Is it a roly poly, Summer
Bugscope Team Not quite. roly polies are not insects, they are actually land dwelling crustaceans called Isopods. this is a beetle, which is vastly different from a roly poly and is a true insect
- Teacher What are the 3 main body parts of insects?
Bugscope Team um, the head, and the ... thorax, and I would say ... the abdomen?
Bugscope Team they also have six legs, as adults, and two antennae
- Teacher Girls--how many legs do insects have?
Bugscope Team just to clarify, you are asking your students and not scott and I these questions?
- Student 6
Bugscope Team yay!
- Bugscope Team sometimes when we see caterpillars, and they seem to have extra legs -- the things that look like extra legs are called 'prolegs'
- Teacher Yep, that was to them, not you guys. Trying to redirect them.
- Student Six
Bugscope Team yay!
- Bugscope Team and juvenile ticks have six legs, but when they become adults they have eight legs
- Student Maria,can you show a picture of a green ant
Bugscope Team Here is a link to a picture of a green ant: http://www.mnh.si.edu/ants/photogallery/images/War_J_104_MM7324_080619_03941.jpg
Bugscope Team It is a weaver ant. They live in trees and use silk produced by their larvae to create nests out of leaves
- Teacher Can we please see one of the butterfly images or bees?
Bugscope Team this, now, is the head of the bee!
Bugscope Team you can see that the bee has little piles of pollen on one of its compound eyes
- Student Paris
- Bugscope Team this is the bee's compound eye in the foreground, and some pollen in the background
- Teacher Do you think bees are allergic to pollen?
Bugscope Team haha I hope not!
- Student Does The pollen feel furry
Bugscope Team it is so very small we may never know how it would actually feel to us
Bugscope Team it is sticky, and it would cling to you like a burr
- Student What do you look like mr Josh.
Bugscope Team Josh is quite presentable when he is not collecting ants.
Bugscope Team google Fabio. That's what I look like :)
Bugscope Team JK
Bugscope Team haha!
- Teacher Is it true that if a bee stings you, it cannot sting again?
Bugscope Team For honeybees this is true. They have barbed stingers that get stuck in our tough skin. For other bees such as bumble bees, and wasps, this is not the case, and they can sting multiple times
Bugscope Team yes as Fabio says, honeybee stingers get caught in mammalian skin, and they pull out of the bee's body. the bee then bleeds out...
Bugscope Team honeybees can sting other insects, for example, multiple times without losing their stingers
- Teacher Which type of bee is this?
Bugscope Team this is a honeybee
Bugscope Team the bee people tell us that only bees have forked, or multi-branched setae (the hairs)
- Student Why does the bee stinger
Bugscope Team Savanah what was the whole question?
- Teacher Fabio, what is above the stinger that looks like feathers. :)
Bugscope Team Those are the bees hairs. the Entomological term for them is setae. Notice that each setae has multiple tinier hairs coming off of them; these are called compound setae ( I think; double checking atm) and are diagnostic of bees (i.e. all bees have compound setae)
Bugscope Team Branched setae is the appropriate term, not compound. my bad guys
- Student Scot our friend Ella just got here could you tell her a little bit about his picture is in the steamer thank you
Bugscope Team above we see a lot of setae, which is what the hairs are called, and they are at the tip of the abdomen. pointing out below is the bee's stinger, and in and among the setae are little pollen grains
- Student Lillian is here to live with her sister Emily
Bugscope Team Sweet!
- Student Why does the bee stinger look pointy?
Bugscope Team The bee has to use the stinger to pierce skin and insect cuticle in order to inject its venom and defend itself and the colony. If it was blunt It would not be very affective. It would be like you went to the doctor and he tried to give you a shot with a hollow hammer.
- Bugscope Team now we see more of the abdomen, and some of the limbs
- Student Cool
- Student Can a bee lay eggs
Bugscope Team the queen does!
Bugscope Team The workers have undeveloped ovaries and so cannot lay eggs as long as a queen is producing pheromones to repress their ovarian development
- Student Summer, Why do bees sting
Bugscope Team A bee uses its sting as a defense mechanism. They sting to defend their hive from potential intruders
- Bugscope Team this looks like a stinger but is actually the stylet of a true bug
- Teacher Is this still a bee? or a butterfly?
Bugscope Team this is a true bug, which is what a stinkbug is and what a bed bug is as well
- Student Can you show a picture of a butterfly
Bugscope Team this is a butterfly
- Student Is this a tongue of a butterfly
- Student I mean Fly
- Teacher What is the spiral part?
Bugscope Team The spiral is the butterfly's proboscis. It can uncurl it and use it to lap up nectar from flowers
- Student Oh Lilian and Emily.
- Student Ella, How many legs do Isopods have?
Bugscope Team I think they have seven pairs and sometimes nine pairs; I am sorry I am not sure.
- Student Lillian and Emily, Can you show a picture of a butterfly
Bugscope Team this is the head of a butterfly. and the spiral part, which is in an odd position, is indeed the proboscis, or tongue
Bugscope Team Scott, are we Lillian and Emily? I thought I was Fabio...
- Student No problem ,Ella
- Teacher They are having some confusion as to where to put their names. They are sharing tablets.
Bugscope Team Gotchya, Josh/Fabio
Bugscope Team haha!
- Student What are the big round things, Emily
Bugscope Team Those are compound eyes
- Bugscope Team we are at the edge of the world in the image we see now -- we are looking over the microscope stage and into the microscope
- Student It has seven pairs of short legs for the Isopod, Summer
Bugscope Team yay! Thank you, Summer!
- Teacher Can we zoom in on the compound eyes please?
Bugscope Team yes we can!
- Student Found it in a book, Summer
- Student What is the hair
Bugscope Team the hair we see so often helps insects sense their surroundings. it is sensory, and depending on the hair, or setae, it can be mechanosensory, chemosensory, thermosensory, and also used for proprioception, which is self-sensgin
Bugscope Team selfsensing...
Bugscope Team In the case of butterflies and moths, most of these hairs are modified into scale like structures, which can easily break off and allow these insects to easily escape from spider webs. They also allow for very colorful patterns to develop in butterfly wings, which they use in mating displays
- Student Is this a compound eye, Summer and Mia
Bugscope Team yes it is!
- Bugscope Team I am going to the microscope itself to drive...
- Teacher Maria is wondering if the spots on the compound eye are healing spots?
Bugscope Team unlikely. Once an insect reaches adulthood it (with very rare exceptions) ceases to grow, including tissue repair like you are speaking of.
- Student What are the scraps on the compound eye, Emily and Lilian
- Student What's your favorite about being a bug scientists
Bugscope Team it is really fun. we are looking at these kind of alien creatures that live around and near us and have to solve many of the same problems we do
Bugscope Team Its a great way to pick up ladybugs ;)
- Student "Are you guys in college?"Mia
Bugscope Team I am! I am currently a masters student. Scott, while "in college" in the locality sense of the phrase (i.e. he works at a university), is not.
- Student What are those lines and what is that, Summer and Emily
Bugscope Team so when we went up to high mag on the compound eye we found that it is very dirty, and it also has loose sva\
Bugscope Team scales on it, which Josh/Fabio had mentioned.
Bugscope Team this is one of the scales, and the horizontal lines we see are so small that they interfere with visible light and can cause you to see interference colors, called strructural colors
- Teacher what is this?
Bugscope Team this is part of a wing scale on the eye of the moth
- Student What kind of bug is this, Summer
Bugscope Team we are still looking at a butterfly, just extremely close up
- Student You guys are funny and fun.
Bugscope Team yay! Thank you!
- Student What did the cockroach say to the other?
Bugscope Team uhoh... I don't know
- Student You bug me
Bugscope Team haha! of course!
- Student Josh how old are you?
Bugscope Team 22
- Bugscope Team the things in all of the little compartments are pigment granules
- Student Ant-arctica
- Student What do you get when you cross a pig and a centipede
Bugscope Team a centipig?
- Teacher why do cockroaches eat wood houses?
Bugscope Team oh no? are we supposed to know this?
Bugscope Team I give up.
Bugscope Team Is this a joke or a question lol?
- Student No bacon and legs
- Teacher what is this? Emiy
Bugscope Team thatr \\
Bugscope Team sorry cannot type
Bugscope Team that was (bacon and eggs!) one of the scales, but on end.
- Student What is the biggest ant in the world?
Bugscope Team Dinoponera are the biggest in terms of worker body size
- Bugscope Team this is the stinger of one of the smaller ants
- Student I ment to say why do termites eat wood houses
Bugscope Team um because they can digest cellulose?
Bugscope Team to get to the other side (termites are extreme parkourers)
- Bugscope Team this is a mutant rabbit
- Teacher can you show a fly?Emily
Bugscope Team yes we can!
- Bugscope Team this is the fly's head
- Student My question is not a joke
Bugscope Team ... neither was my answer ;)
Bugscope Team JK
Bugscope Team Termites are decomposers that typically consume dead plant material, mainly wood for most species. Since we make our houses out of piles of dead wood, its like a buffet to them
- Bugscope Team this is a fly!
- Student "Thanks" Mia, Summer.
- Student Thank you for answering our questions
- Bugscope Team Question for the Kids: How many wings does a fly have?
- Teacher thanks,Emliy and
- Bugscope Team Thank you, everyone.
- Student 5 Mia and Summer
Bugscope Team just a teensie bit high there M&S
- Student 4
Bugscope Team Most insects have 4 wings, but not flies :) good guess though
- Bugscope Team this fly has only one wing and so far we can see only one haltere
- Student This was fun.lol
- Student Bye M&S
- Student 2
Bugscope Team yay!
Bugscope Team Diptera is the same as di ptera, which means 'two wings'
Bugscope Team most flies have 2 wings and a pair of halteres, which used to be wings but are now reduced to gyroscope-like structures which help stabilize the fly as it flies
Bugscope Team There are some unusual wingless parasitic flies as well. They're not the norm for flies though
- Teacher what is this?Emily
Bugscope Team this is the back of the fly -- we can see part of a wing, and we can see the haltere, which is very small, and the thorax and part of the abdomen
- Bugscope Team Thank you so much for working with us! This was indeed fun!
- Bugscope Team See you next year!
- Student "Bye Josh and Scot"Mia and Summer
Bugscope Team so long! farewell! auf wiedersehen! goodbye!
- Bugscope Team Bye Everyone!
