- Bugscope Team piump
- Bugscope Team pumping down
- Bugscope Team did not suddenly learn to type overnight
- Bugscope Team kind of disappointing
- Bugscope Team about ready to click the gun on
- Bugscope Team We are ready to roll, early this time.
- Bugscope Team Good morning!
- Bugscope Team Welcome to Bugscope!
- Bugscope Team We can confer control of the microscope to whoever you want at any time, just let us know
- Student What is this?
- Bugscope Team this is the surface of the exoskeleton of a spinose eartick
- Bugscope Team 'spinose' means it has spines, and these are some of the spines
- Bugscope Team Hi!
- Bugscope Team Let us know if someone would like to drive the microscope, as Cate had mentioned.
- Bugscope Team Group 6 has control now.
- Bugscope Team the presets in the lower right are clickable for those that have control of the scope
- Bugscope Team this is the base of one of the spines. These are soft ticks, which we had not seen before.
- Teacher Can you please give control to Group 7
- Student cool, does eartick mean it lives in your ear?
Bugscope Team it seems they do go for ears, this one goes for livestock though
- Bugscope Team It is likely they have been found in ears before. They probably crawl there and settle in for a little while.
- Student what is this?
- Bugscope Team now you can see that it is indeed swollen with blood
- Teacher Can this tick give you cancer
Bugscope Team likely it cannot give you cancer, but some ticks can give you bad diseases, like Lyme Disease.
- Student how long does an eartick live
- Bugscope Team those are its arms
- Bugscope Team the spinose ear tick is a pest of cattle, horses, sheep, and goats
- Student can you coat the objects in any other types of metal
Bugscope Team yes: platinum, gold, silver if we wanted to
- Student gross...
- Teacher can this tick be deadly to some animals or humans
Bugscope Team yes they can cause tick paralysis, that can eventually cause death
- Student may we view a different bug?
- Student Can humans get these ticks?
Bugscope Team there is an article on line about one being found on a little girl's eye, or right next to it
- Student how long do they live for?
Bugscope Team The larvae and nymphs feed from 1 to 7 months, and, when feeding, become almost spherical like this one. They then drop off and become adults that aren't parasitic and only lay eggs. So I'm guessing they can live for upwards of a year
- Teacher correction (Do ticks have hair)
- Teacher can the Eartick reproduce very quick
Bugscope Team Sometimes. The eggs are dropped off in a secure location, usually a moist area perhaps under leaves or debris. In warm conditions, oviposition will start in one to two days following copulation. In colder conditions, females may wait months to oviposit eggs.
- Student what does a honeybee eat
Bugscope Team they eat nectar and honey
- Student What are the claws for?
Bugscope Team many different insects, or in this case crustaceans, will have claws that are used to grab onto things like food
- Teacher is that its legs and how many legs does it have
Bugscope Team I think most of them have fourteen legs
- Student rolly-polies are awesome
Bugscope Team yes this one is particularly cool-looking
- Teacher What is this
- Student Is that a stinger?
Bugscope Team yes!
- Student whut is this
- Student what kind of metal do you coat it in?
Bugscope Team gold-palladium; we use a sputter coater that puts only a few nanometers of metal on the surfaces we're looking at
- Student What is the stinger made of?
Bugscope Team The stinger, along with the exoskeleton, is made of chitin, which is the same stuff your fingernails are made of. It is very tough stuff
- Teacher why is this so big
- Bugscope Team the wasp can sting repeatedly, and it does not have recurved spines that make the stinger stay in your skin
- Student Can we magnify it more?
Bugscope Team yes you can
- Student how long can wasps live?
Bugscope Team usually a season or less. it usually depends in part on what the function of that wasp is. and some are solitary
- Teacher Can you please give control to Group 8? Thanks!
Bugscope Team got it!
- Student What is this
- Teacher isn't this a honey bee
Bugscope Team This is a wasp, the honeybee has a barbed stinger
- Bugscope Team there is also a honeybee on this stub
- Student dont males get pollen and they have the stinger
Bugscope Team No. Females are the workers. Males are drones and they sit "at home" and are waited on by the workers. Their only purpose is for mating
- Teacher that looks like a cow face
- Student What are the little hairs for?
Bugscope Team the little hairs, called setae, have many functions
- Bugscope Team see the jaws? they open side to side. we are just above there now
- Bugscope Team that is called the clypeus, above the mouth opening
- Student is it used for eating
- Student Is the big thing in the middle a nose?
- Student what are the eyes made out of
- Student hi
- Student hi
- Teacher I have been told that Honey bees don't sting you unless they have to. Is that true.
Bugscope Team they are conservative about stinging because it will kill them
- Student What are the pinchers for?
- Bugscope Team setae ('see-tee') are sensory, sometimes; they can feel touch and sense hot/cold; they can also, some of them, taste chemicals in the air
- Teacher What do the honeybees do with their jaws
Bugscope Team they chew up the pollen/nectar and mix it with saliva to make honey
- Teacher how big can the average honey bee get to
Bugscope Team they usually get to a certain size and don't keep growing; their ultimate size depends on what they are going to be doing
- Student Don't honeybees only sting you when you mess when their hive, or are they afraid of you?
Bugscope Team honeybees are very non-aggressive. They will usually only sting you if you like step on them or really mess around their hive. Wasps are the aggressive ones
- Student Whats that
- Teacher do honeybees see color like us.
Bugscope Team they see some colors and not others; they don't see all of the colors we see
- Student What is the honey be claw for?
- Student What purposes do the claws of the honeybee have
Bugscope Team They are there to help grab things or to help stay on things like flowers or whatever they want to cling to
- Student Is this a leg?
Bugscope Team this is the claw, at the end of one of the tarsi
- Student do honybees sting you in any specific place, i know a guy who got stung twice in the same spot
- Student What is this?
- Teacher do honey bees have better eye sight than humans
Bugscope Team in some ways they do -- if you had compound eyes like that you would have better peripheral vision and be better able to sense motion
- Student Is that nectar/pollen on the leg?
- Student can honeybees see any other part of the electromagnetic spectrum
Bugscope Team they may be able to see in the ultraviolet; I'm not sure though
- Student what is the bigger thing in the middle?
- Student what is a tarsi?
Bugscope Team tarsi are the final segments of the leg or arm
- Teacher do male honeybees mate with the female every other year
Bugscope Team I have read that the queen flies far away so that she can mate with males from other colonies, not hers
- Student do hornets have a relation to wasps
- Student why do bugs have so many circles in their eyes
Bugscope Team the shape we see, of the individual facets, called ommatidia, is hexagonal, as you can see, and it is a good shape to be if the eye is round and bulbous
- Teacher what is the general life span of a honey bee without it stinging someone
Bugscope Team The length of a female honeybee's life depends on when she emerges from her cocoon. If she emerges in the early spring, she may only live for a few weeks as she prepares the hive for lots of new bees. Workers who emerge later may live through the winter.
- Student Is this from the bee
- Student Do lady bugs see multiple images?
- Teacher Is this a ladybug eye
Bugscope Team yes this is the ladybug eye, and it has many ommatidia, which are the individual lenses
- Student How many lenses does the lady bug have on its eyes? It looks like they have alot
- Student Do the cracks affect its vision?
- Student what is the little spike in the middle of the eye
Bugscope Team that is a single seta, or hair, on the eye. Many flying insects will have these to help tell the insect the direction the wind is blowing
- Teacher Why does the female honeybee mate with other male bees form diffrant collines
Bugscope Team I imagine it is a behavior that has evolved to ensure that the colony does not suffer from inbreeding
- Teacher Bees have cocoons
Bugscope Team yes. Once she lays eggs, the eggs go through the same stages as caterpillars and butterflies do. First they hatch into larvae. The larvae eat before spinning cocoons and becoming pupae. They then emerge from the cocoons as adults.
- Student what is the ommatadia
Bugscope Team ommatidia (ommatidium, singular) are the facets of the compound eye
- Student Do ladybugs blink?
Bugscope Team no they do not have eyelids
- Student Can you please give control to group 3?
- Teacher Is a honeybee related to hornets and wasps
Bugscope Team honeybee, wasps, and ants are all in the same order- hymenoptera
- Teacher What is that
Bugscope Team this is a low mag image of the ladybug, and the background is the stub covered with carbon tape that we stick the insects on
- Teacher what is hymenoptera
Bugscope Team Hymenoptera is the order to which bees, ants, and wasps belong
Bugscope Team The name refers to the heavy wings of the insects, and is derived from the Ancient Greek humen: membrane and pteron: wing. The hindwings are connected to the forewings by a series of hooks called hamuli.
- Teacher Do bugs breath often
Bugscope Team they breathe through their spiracles, and presumably as necessary
- Student how big is the microscope
Bugscope Team it is in two parts, comprised of a part that is as big as a large desk and another part that is about the size of a fridge
- Student How big is the microscope you are using?
- Teacher Have you ever had a bug blow up
Bugscope Team yes but not that dramatically
- Teacher oh
- Teacher how many legs does a millipead have
Bugscope Team that depends on the length of the millipede. They have two pairs of legs per segment (except for the first segment behind the head which does not have any appendages at all, and the next few which only have one pair of legs).
- Teacher Do millapeeds have eyes
Bugscope Team yes they do
- Bugscope Team spiders sometimes give off gas and will shut down the microscope briefly
- Student is there any dangers to you with the use of this microscope
Bugscope Team in the old days there might've been a problem with x-rays, but now we are pretty well protected
- Student What is that goo stuff on the leg?
- Student How much does it cost to coat a bug?
Bugscope Team we charge I think about $7
- Student What are the lumps on the legs?
- Bugscope Team you could also get shocked if you were touching the wrong thing, but usually you stay away from those places
- Bugscope Team Insects breathe through openings that lead the oxygen through a trachea. The trachea run through the whole insect body. The amount of inspired oxygen is limited with such system. This may be the answer why insects don't grow much larger than 10 centimetre. In prehistoric times, when there was more oxygen in the atmosphere, insects could grow to much larger sizes.
- Teacher then why are there antenas coming out of the eye socket
Bugscope Team it looks like an eye socket but it really the antenna socket. we think the eye should be there because we think about ourselves, but antennae are sometimes more important than eyes
- Student do you have to be in a different room than the microscope
Bugscope Team we dont have to be, but we usually are. Sometimes we will have our own entymologist log in and help us out
- Teacher do bugs have blood
Bugscope Team they have what is called hemolymph, and it is often clear, or yellowy
- Student How many bugs do you have there?
Bugscope Team we have lots of different kinds, but we usually limit the amount we put on a sample for bugscope to about 10, usually less.
- Teacher what does( ')this mean
Bugscope Team It means we are quoting the original question or statement, and we are answering
- Student could we have a coated bug????=)
Bugscope Team you could; it would look silver; but it would be fragile
- Teacher the anteena socket looks hairy
- Teacher what is this
Bugscope Team this is a tick claw
- Teacher okay thanks
- Student haha yellowy is a funny word
- Student what are we looking at now
- Teacher is that a hook
Bugscope Team Yes, that is the tick's form of a claw
- Student Why isn't the claw very sharp? What is it used for?
Bugscope Team it may not look sharp but they are. This high of a magnification makes things not look as sharp. You'd be surprised but how blunt a hypodermic needle may look
- Teacher Do they use it for defense?
- Student could u coat an elephant
Bugscope Team the chamber is very small, and we would have to do it in small pieces
- Student are you able to use this microscope to view any size organism
Bugscope Team the size is limited to about a couple inches in length and height
- Student Can you gold coat anything bigger than a bug?
- Student is this what they use to cling to walls
Bugscope Team these claws are very small that they could probably cling to a wall that is textured, but usually the insects that cling to walls have special pads of hairs at the end of their legs that act as velcro or suction cups
- Teacher can you code a cat
Bugscope Team similarly, it would have to be done in pieces, not pretty to imagine
- Student why dont insects have blood
Bugscope Team it is interesting -- they are different life forms compared to us, and they do so many things in what we think are odd ways
- Teacher do ticks have more than one mouth
Bugscope Team just the one
- Student what is this
- Teacher I thought you said bugs have blood. Right?
Bugscope Team hemolymph is like blood to an insect, but it is not really blood
- Teacher Since this bugs eyes is on the side of its head does it have to turn its head to see
Bugscope Team no it has better peripheral vision than we do; it does not have to turn its head
- Student what is this
- Student Does this insect suck blood?
Bugscope Team the image before this that had the weird looking blood can. Those types of insects, called true bugs, have a mouth part called a proboscis, which it uses to drink liquids like bug blood or plant sap
- Teacher then how do they live
Bugscope Team they use the hemolymph sort of like we use blood, but I don't think it carries oxygen like ours does
- Student Can you please give control to group four?
- Teacher yes some bugs suck blood right
Bugscope Team yes they do; it is nutritious but does not serve the purpose our blood does for us
- Student how can this microscope zoom in so far?
Bugscope Team it is using electrons to image, instead of light. Electrons are much smaller and so they create better resolution images. That is also why we are imaging in black and white
- Bugscope Team "weird looking bug"
- Student couldl you mail us a coated bug
Bugscope Team sure!
- Teacher then do they even carrie oxegen
Bugscope Team the oxygen gets into the organs via tracheae that are connected to the spiracles
- Student Do bugs have hearts?
Bugscope Team they have organs that are like hearts, but they do not have a closed ciculatory system with veins and arteries like we do
- Student cool!
- Teacher what is this
Bugscope Team this is showing the honey bee eye and part of her head to the right
- Teacher do some bugs have bones
Bugscope Team in a way. They have all their bones on the outside- an exoskeleton. Exo meaning out or outside
- Student when are u going to mail it to us thanks and that cool
Bugscope Team please ask your teacher to remind us
- Teacher what does via tracheae
Bugscope Team oxygen comes into the spiracles and is distributed through the inside of the body via the tracheae
- Student What are the hairs for?
Bugscope Team hairs are used for various things like touch, smell, taste, etc. You must remember they have a hard shell around them and without those hairs they wouldnt be able to feel anything
- Teacher then does that mean that muslce supports the inside of their body
Bugscope Team yes there are lots of muscle attachments to the inside of the exoskeleton
- Teacher I sthis like a leg of a honeybee or something
- Student wat is this
- Student do lady bugs smell scents with there antenna? =)
Bugscope Team I believe they can; most insects can smell using their antennae, and they can sometimes smell with other setae not on the antennae as well
- Student why do you have to coat the organisms with metal
Bugscope Team without the metal, the insects aren't very conductive. The specimens have to be conductive to get good images with an electron microscope
- Teacher what is photosyhthises have anything to with bugs
- Student What metal gives the best image?
Bugscope Team gold-palladium is very good because it is so fine; we cannot see it unless we are at a super high mag
- Student why
- Teacher do bugs smell
Bugscope Team yes they can, and yes they do, sometimes
- Student are those setae on the legs? i here some flies taste with there feet .
Bugscope Team Monarch butterflies famously taste with their feet, using setae on their feet.
- Student why do you only use bugs? why not a snake or frog
Bugscope Team insects, when they are dead and dry stay in the same shape as when they were alive usually, because of their exoskeleton. Snakes and frogs will not only take a while to dry out, but they will shrivel quite a bit after they die.
- Student Do bugs have a brane?
Bugscope Team yes they do have a brain and a nervous system to go with is. The hairs you see are all connected to nerves underneath the exoskeleton
- Student Do you do any thing else with that microscope
Bugscope Team yes we teach researchers to use it to do their work, and usually it is not with insects but with other things they study
- Teacher hypathetically if a bug couldnt find food would it resort to chanabalism
Bugscope Team yes they often do
- Student What metal gives the worst image?:)
Bugscope Team gold alone makes a chunky surface
- Teacher Are these things hair or antennaes
Bugscope Team those are setae
- Student we thinkthe hair in the middle is moving is this possible?
Bugscope Team it is possible because sometimes the electrons can move the sample slightly
- Teacher why do bugs eat each other
Bugscope Team just because they are hungry; ladybugs, for example, feed on other insects
- Student why do bugs not eat human food like small pieces of lucky charms
Bugscope Team some do, like ants or some beetles. Also wasps like to eat our garbage, you may see them buzzing around your trash or picnic table
- Student how high of an electron beam do you use (power wattage)
Bugscope Team we are using 5000 Volts but just microAmps of current, so probably a few hundred Watts
- Teacher What is this suppose to be?
- Student How was the SEM devoloped?
Bugscope Team the SEM was developed after the concept was perfected using the transmission electron microscope (TEM)
- Student Can bugs feel pain?
Bugscope Team yes they can
- Teacher who invented all the microscop
Bugscope Team The first SEM image was obtained by Max Knoll, a german scientist. Transmission electron microscopy was developed first I think
- Student If we were to be hit by the electron beam that the microscope uses could it harm us? If not what would happen?
Bugscope Team It would be very harmful. Electron beams can boil things, or make things explode easily.
- Student how many lightbulbs would one hundred watts power
Bugscope Team one to four, generally
- Student `why dont you use a hard plastic or glass to coat the bugs?=)
Bugscope Team those are not conductive
- Student What is the shiny stuff in the background?
Bugscope Team that is some oil that got on the insect, most likely after it died
Bugscope Team it's shiny because it isn't very conductive
- Bugscope Team we need to have something conductive to carry the excess electrons to ground, or else we will not get good images
- Student why do you have to use a conductive metal
- Student Can you please give controle to group 8?
- Student do u now how many bugs are in the world :)
Bugscope Team there are around 925,000 species
- Student Will you show us some bugs coated in a different metal?
Bugscope Team it wouldn't look very different under the microscope. Right now, these insects are coated with gold/palladium alloy, which makes the sample look silvery. We can also coat with gold or platinum.
- Student what is the shiny stuff in the background
Bugscope Team that was an oily coat of something, some kind of juju
- Teacher If we were to be hit by the electron beam used by the (SEM) would we be harmed ? if not what would happen?
Bugscope Team the electron beam would not be coherent in the air -- it would not work well
- Student what do the holes do?
Bugscope Team those are called placoid sensilla, and they may may chemosensory or perhaps just self-sensory, telling then insect if its antennae are bending
- Student does the room have to have special material for the microscope to operate well
Bugscope Team we keep the main component of the microscope on an air table to help eliminate vibrations. Vibrations are bad when it comes to using this microscope
- Student do you use a platinum coating often if not which do you use most often
Bugscope Team no we don't use it often because it is a little expensive. Maybe a couple times a year
- Student What is this?
- Student can you please give control to group 12
- Student what is this
- Teacher what are the pointy things
- Student Which metal do you use the most often?
Bugscope Team We use gold/palladium because it coats smoother on the sample
- Student what are the dented crators
Bugscope Team those were the placoid sensilla
- Student Which bug is the best for this?
Bugscope Team well, insects that are super hairy or have lots of scales, like moths, are harder to coat well
- Student does the room have to have special material for the microscope to operate well
Bugscope Team no it is just normal, but there are no electrical fields that will mess things up
- Teacher what is the highest magnification on the (SEM)?
Bugscope Team this microscope can go to around a million X, but we can't see much beyond 200,000x.
- Student what is the flat thing on its face
Bugscope Team that is called the clypeus
- Student could you use a non living thing with a coating? Say a chair coated in gold platinum.
Bugscope Team yes we could
- Student does the room have to be at a certain temperature for the microscope to operate
Bugscope Team it works better if it is a little cool so that the instrument and the computers do not overheat
- Student How do you get the bugs? Do you just find them, or breed them for the microscope?
Bugscope Team people bring them, send them, we collect them sometimes
- Student how many legs does this bug have?
Bugscope Team six; all insects as adults have six legs
- Student the things under the clypeus, what arethey called
Bugscope Team the jaws, and also the palps, mandibular and maxillary palps, two of each
- Student Please give control to Group 4
- Student what are these hairs for
Bugscope Team These are probably mostly for touch sensations
- Student what would a coated desk look like, would it be like a shiny desk or like this buggy here?
Bugscope Team it would look shiny if the wood was very smooth
- Teacher are there any specific preparations you have to make before you coat the bug?
Bugscope Team we like to make sure the parts we would like you to see are not obscured by other parts
- Student why do humans kill bugs
Bugscope Team The main reason is because they are pests, like to farms or animals or our homes.
- Student What would happen if you mixed all the metals?
Bugscope Team they would look silvery
- Student do bugs like to live in one spot until it dies or does it move from place to place
Bugscope Team some insects move a lot, and some stay in one place. similar to spiders, which are not insects; some of them are territorial and stay in pretty much one place unless they are disturbed
- Student do you use a mix of the metals
- Student what this
- Teacher how does the microscope produce the electrons?
Bugscope Team the electrons come from a filament sort of like the wire in a lightbulb
- Student wat would happen if a living organisim was put under the SEM? would it die slowly or quickly
Bugscope Team If we were to put it in the microscope, we have to bring the chamber it is in to vacuum. I think it would die pretty quickly. It wouldn't be able to breathe. Insects can hold their breath a little bit though.
- Student Is the different ;layers on the outside hard like armor
Bugscope Team yes it is just like if we were wearing a suit of armor
- Student do you use a mix of the metals for coating
Bugscope Team yes gold:palladium, and I think it is 70:30 but not sure now
- Student What is that?
Bugscope Team this is a rolly-poly
- Student do bugs live on humans
Bugscope Team There are mites and ticks and lice that do
- Student What does the trunklike thing on the true bug do?
Bugscope Team it is part of the piercing mouthparts, and it pierces plants or insects and sucks out juices
- Student what kinds of materials do you use to coat bugs
Bugscope Team gold-palladium and silver to help with conductivity but not to coat
- Student what mix of metals is gold:pallidium
Bugscope Team those are both elements, the element gold and the element palladdium
- Student does a rolly polly have a face+
Bugscope Team yes it does; this one is kind of cute
- Bugscope Team oops palladium (sp.)
- Student What is the chemical mixture for pallidium?
Bugscope Team palladium is an element like carbon or oxygen, etc.
- Teacher if the bugs are coated in metals how do you see the actual bug?
Bugscope Team the metal is only a few nanometers thick, very very thin
- Student what is this grayish serfsce of
Bugscope Team it looks gray because we are getting signal from the electrons that come back from the sample; we are not able to collect color
- Student chaos,do you collect bugs often are they usually live or dead
Bugscope Team we usually get them dead, but every now and then we get them alive and we stick them in the freezer where they die a more "humane" way
- Bugscope Team Chaos and Console are the logins we used when we were in the microscope room. Now we're in our offices.
- Student how to you get these bugs and are they dead when you get then. Have some bugs beenmixbreaded like dogs.
Bugscope Team usually they are dead, but sometimes we freeze them. some insects can crossbreed, and that is what was expected to happen with the africanized honeybees
- Bugscope Team that is, some people expected that the super aggressive African honeybees would breed with normal bees, and the hybrids would not be as mean
- Teacher Thank-you so much, BugScope! Our class time is over, but we had a lot of fun!
