- Bugscope Teamsetting up...
- 11:03 am
- 11:10 am
- Bugscope Teamhi ms. shapiro, welcome to bugscope!
- Bugscope Teamwe are setting up presets for your session at the moment, will be done soon
- Bugscope TeamGood morning! We are working our way toward the drone and worker honeybees.
- 11:15 am
- TeacherHi- Kids aren't here yet- just setting up computers two teachers and five students stations olay
- Bugscope TeamCool.
- Bugscope Teamno problemo, we are still setting up presets
- TeacherMaybe I can drive on the electronic whiteboard hmm
- Bugscope TeamYou can control the scope from any login, just tell use which login is the whiteboard, and we'll switch control over to that login
- 11:20 am
- Bugscope Teamwe should be able to try once we get these down and can hand over control
- TeacherIt's my computer
- Bugscope Teamok, ms. shapiro login already has control, however, we have the session locked, until we are done with presets
- Bugscope Teamthat makes it easy
- Bugscope Teamas soon as we are done with presets, we will unlock and then the login ms shapiro will see the controls, no problemo
- 11:26 am
- 11:31 am
- Bugscope Teamdone with presets, session unlocked
- Bugscope Teamwe are ready anytime
- Bugscope Teamyou are the supreme rulers
- Student```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````what are we looking at```````````````````````````````````````````````````````````````````
- Bugscope Teamthis is a honey bee, it's head, with the HUGE compound eye
- Bugscope Teamyou can see the antennae, directed forward
- Bugscope Teamnow we are way up on the compound eye and a little OOF.
- Bugscope TeamHello all!
- StudentWhy is it so hairy
Bugscope Teaminsects don't have skin like humans do, they have an exoskeleton without nerves in it. so those hairs stick through the exoskeleton, to nerves underneath, and thus transmit information about the environment to the insect
- Bugscope TeamAnnie!
- Bugscope Teaminsects are a lot hairier than they first appear to be. This is a hairy eyeball
- 11:37 am
- Bugscope Teamthose hairs are called setae (see-tee) and they can sense lots of things: movement, smells, temperature, etc.
- Bugscope TeamThe hairs on the bee's eye help it to fly and sense direction in the wind
- Bugscope TeamWe see setae on the surface of the fruit fly eye as well. In that case the fly gets information about wind speed and direction from the setae. Oops, Annie just said that.n the fruit fly,
- Bugscope Teamthe drone is a male fly, and it does not have a stinger. it is larger than the worker honeybee, which is a female and does have a stinger.
- Bugscope Teamthe drone has much larger eyes as well.
- Bugscope TeamI mean a male bee, sorry.
- Bugscope Teamlet us know if you have any trouble driving
- Studentwhre should we go to see the stinger?
Bugscope Teamms shapiro can click on a preset for the stinger, that is preset #12, but you'll have to zoom out once you get there
- Studentcan we see the stinger?
- Bugscope Teamms shapiro has control of the scope, she can click on preset #12, that is a close up of a bee stinger
- 11:42 am
- Bugscope Teamthis is preset #11, butterfly wing scales
- Bugscope Teamthe butterfly is a black swallowtail
- Bugscope Teamthe bee stinger is preset #12
- Studentwhy does it look so flakey
Bugscope Teamthose are all scales
- Studenthow far should we zoom out?
- Bugscope Teamthe same stuff that looks like powder on your fingers
- Bugscope Teamthis is not the stinger, these are scales on a butterfly, you need to click on preset #12 for the stinger
- Studentwere is the stinger
- Bugscope Teamthe stinger is here but it is hard to see
- Bugscope Teamthere is a scale to the left of it
- Bugscope Teamstinger is now centered, with pollen grain at the tip
- Bugscope Teamyou can see a butterfly or moth scale to the left of it
- 11:48 am
- Studentwhere can we find the pollen basket?
- Bugscope Teamwe have two worker bees in the 'scope today, and neither has a prominent stinger
- Studentpreset for pollen basket
- Studenthow much polloen can a pollen basket carry
Bugscope TeamUp to 1 million grains of pollen (for a bumblebee, anyway)
- Bugscope Teamthe pollen basket is on then hind leg
- Bugscope Teamthe hind leg
- Teacheris this the pollen basket
- Bugscope Teamyes I think it is
- Bugscope Teamof course it is not really a basket
- Bugscope TeamI think these are the combs. The pollen basket is usually smooth
- Studentwhat is the pollen basket made of
Bugscope TeamThe pollen basket, like all parts of the bee's body, is made of cuticle--the exoskeleton
- 11:53 am
- Bugscope Team(Listen to Annie)
- Studentwhy are there less bees then they were before?
Bugscope TeamNo one really knows. It is likely there are combination of factors that have led to the decline of honeybee populations. Those factors include parasites and diseases, and insecticides in the environment. Bees have fairly simple immune systems and they can't really deal with pesticides.
Bugscope TeamThe decrease in honey bees are due to a colony collapse disorder (CCD) which has been said to be caused most likely by the IAPV (Israeli Acute Paralysis) virus. Annie can probably give a better answer than me about that though
- Studenthow big is the pollen basket
Bugscope TeamMaybe 3-4 millimeters long
- Bugscope TeamI am going to drive to another bee and see if we can find the basket. It is said to be on the hind tarsi but I am not sure that is right, from the images I have seen.
- Bugscope Teamlately the honey bee populations haven't been doing too bad according to some recent news stories
- Bugscope Teamat least global populations have been better
- Studenthow does get the necter out of a flower?
- Studentwhat is the difference between the pollin comb and the pollin brush
Bugscope TeamThe comb is what actually collects the pollen from the plant. The bee moves the pollen from the comb and packs it onto the basket, for storage.
- Studentwhat is the size of the largest bee in the world
- Studenthow does the bee collect the nector?
Bugscope TeamIt sucks the nectar through its mouth, part of which is shaped like a straw
- Studenthow do the bees make the hives
- Studentwhy are bees black and yellow
Bugscope TeamIt seems like the black and yellow (dark and light) color combination is common in insects that sting. It is a warning to other animals to stay away.
- StudentHow do bees make there honey?
- 11:58 am
- Bugscope Teambees are attracted to blue colors rather than reds
- TeacherWill preset 17 let us see the mouth?
Bugscope Teamyes it will
- Studenthow do mites kill some bees?
Bugscope TeamThere are several kinds of mites that can kill bees. One type of mite lives inside the bee's trachae, which are its lungs. The mites clog up the breathing system and the bee suffocates. Another kind of mite, the varroa mite, causes the bees to be deformed, altering their behavior and making them less efficient at doing their little bee jobs.
- Studenthow long is the bees probiscis
- Bugscope Teama hover fly also has black and yellow stripes on it, which is its defense mechanism, even though it is harmless
- TeacherIs this the jaw
Bugscope Teamnear the top of the image is the hinged jaw that opens out like a gate
- Studenthow long can a live?
Bugscope TeamWorker bees live about a month
- Studentwhat do bees eat
Bugscope TeamBees eat pollen and honey. Queen bees eat "royal jelly" which is higher in protein and causes a regular bee to develop into a queen.
- Studenthow long can a bee sleep?
- Studentwhat do mites look like and whare do we find the picture
Bugscope TeamMItes look like little ugly ticks. I am not sure if there are any mites on this sample. Usually bees that are infested with mite are so sick that they just die. They are not usually collected except by bee keepers.
- 12:03 pm
- Bugscope Teamwhen we receive live insects we often freeze them. Sometimes like with ants and bees, they will wake back up after thawing them
- Studenthow many hairs does it have
Bugscope TeamWaaay too many to count!
- Studentwhat's a trachae?
Bugscope Teamin insects the the tracheae are the network of tubes on the inside of the body that spread air -- oxygen to the internal organs of the insect
- TeacherI'ma beekeeper
Bugscope TeamThen I better make sure my answers are correct!! You might have better answers that I do!
- Studentdo bees lay eggs
Bugscope TeamIn a honeybee hive, only the queen will lay eggs.
- Studentwhy does it have so many holes in it
- Bugscope Teamabout the pollen basket, it is smooth and found on the outer edge of the tibia of the bee
- Studenthow big is agrain of pollen
Bugscope Teamthey are about 20-30 microns big
- 12:08 pm
- Bugscope Teamthis is a pollen grain -- an unusual one
- Bugscope Teamor micrometers
- Bugscope Teamyou can use the micron bar on the lower left of the image to help estimate the diameter of this grain
- Bugscope Teamthere are 1000 micrometers in a millimeter
- Studenthawe meney bees does it take to pollinate a flawer
Bugscope TeamIt only takes a single grain of pollen on a single bee to pollinate a flower.
- Studentwhat do bees do when not pollenating
Bugscope TeamA honeybee hive will have workers that do many different things. Some workers keep the hive clean, some take care of the baby bees, and some forage for pollen. When the foragers are not foraging, it is night time, and I think that is when they "sleep"
- TeacherWhat did I do here
Bugscope Teamis something wrong with your image?
- Studenthow do bees clean themsefs
Bugscope TeamThey clean themselves using brushy hairs on their legs.
- Studenthow much bigger is the queen bee than the other bees
Bugscope TeamAbout 1/2 times bigger. She can be hard to see in a hive unless you are really looking for her.
- TeacherI see text at the top
Bugscope Teamwere you able to fix it?
- Studentwhat are bees enmy
Bugscope TeamThere are parasites like mites that can harm bees. There are also some beetles that can get into hives and eat the baby bees (larvae). There are some caterpillars that can destroy the wax in a hive. And many mammals, like skunks, racoons and bears will tear open and eat a bee hive.
- Bugscope TeamMs S I recentered the image of the pollen grain so your class could see the whole grain next to the micron bar.
- Bugscope TeamOh that is from clicking on the micron bar. You can click on it again to make it go away.
- Bugscope Teamlet us know if that does not work
- Teacherhow do I close the menu at the top
Bugscope Teamclick on the micron bar, on the lower left
- 12:13 pm
- Bugscope Teamthis is the tip of the antenna of the butterfly Cate put on the stub for today
- Studentwhen does the queen bee leav the hive
Bugscope Teamin some cases the queen bee leaves the hive when she wants to start a new colony
- Studentare all the bees in a hive rilatid to the quen
Bugscope TeamIn most cases the worker bees are the daughters of the queen. However, in some cases, a replacement queen can be introduced into the hive if the old queen dies...Ms. S. can tell you more about that though ;)
- Bugscope Teamthe queen bee also leaves the colony to breed, and she goes far away to avoid mating with bees from her own colony
- Studentwhat is royal jelly made of
Bugscope Teamroyal jelly is made of digested pollen, and honey, and sometimes nectar; it also has a chemical secreted from a gland in the head of another bee -- called a nursing bee
- 12:19 pm
- Studentwhat are the black little dots?
Bugscope Teamthat is where setae (aka hairs) have fallen out
- Studentwhere can you get it?
- Studenti me anthe royal jelly
Bugscope TeamYou can buy royal jelly at some health food stores. I don't know if I have ever had it, so I can't tell you what it tastes like.
- Studentsorry imean the royal jelly
- Studentcool :)
- TeacherThanks for ansering our questions our next class will be in shortly
- Studenthow big is the stinger?
Bugscope TeamProbably 2-3 mm long. It is not very long.
- StudentBYE!!!! :):):):):):):):):):):):
- Bugscope TeamBye! Thank YOu
- Studenthow do inteni help buterflys
- Bugscope TeamAntennae help the butterfly to sense its environment.
- 12:24 pm
- TeacherCan we start a new session fo rthe next class?
Bugscope Teamyou bet!
- Bugscope TeamThe antennae have sensors in them that allow the butterfly to smell chemicals in the air.
- Bugscope TeamHammuli. I will have a hammuli on rye with mustard
- Bugscope TeamMs Shapiro we are ready.
- TeacherThe next class isn't here yet
- TeacherI've logged in the teacher under student by mistake
Bugscope Teamyou can log her out and go back in as teacher if you would like
- Bugscope Teamlet us know how we can help. I am sorry we don't have good stingers today, and it is hard to find the honey basket, which is just a smooth area on the outside of the tibia of the bee's hind leg.
- 12:30 pm
- TeacherWe are here now and ready to begin the session with Mrs. Happnie's class,
- Bugscope Teamgreat! welcome to Bugscope!
- Bugscope Teamthis is the surface of the compound eye of a honey bee
- StudentIs that hair on the bees eyes?
Bugscope Teamyes you are correct!
- Bugscope Teamyou can see the facets of the eye, and you can see that there are lots of setae (the things that look like hairs)
- Bugscope Teambees and many other insects are very hairy
- StudentWhy do the bees have hair on their eyes?
Bugscope Teamwe think that, like fruit flies, the hairs help the bees sense wind speed and direction as they fly
- Bugscope Teamthe compound eye is made of many individual facets, each of which functions like a lens, called ommatidia
- Bugscope Teamwith insects we call hairs 'setae,' or 'microsetae,' or 'trichae,' or 'microtrichae.'
- 12:36 pm
- Bugscope Teamthis is a big pollen grain, kind of unusual, on the exoskeleton of the bee
- Bugscope Teamit's lodged against one of those setae
- Bugscope Teamthere are thousands of setae -- of 'hairs'
- StudentWhy does the grain of pollen have holes?
Bugscope Teampollen grains have a variety of shapes, and some of them do have holes like this. it may be that the holes help the pollen grains drift further in the wind
- Bugscope Teamthis grain is 20 or so microns across
- Bugscope Teamthis is a bee's knee
- Bugscope Teamthere are 1000 micrometers (microns- um) in a millimeter
- Bugscope Teamthe abdomen is to the right
- Bugscope Teaminsects often have lots of what look like hair -- all over their bodies
- 12:41 pm
- Bugscope Teamthe pollen basket is a smooth area on the outside of the tibia of the hind legs
- Bugscope Teamat this level it is hard to distinguish it
- StudentHow much pollen can a pollen bascket hold?
Bugscope TeamUp to 1 million pollen grains
- Bugscope Teamactually we may be looking right at it here
- Bugscope Teamlet's take the mag down and see if this is the pollen basket
- StudentWhat is that rectangle at the top of the screen.
- Bugscope Teamwe need to drive north
- Bugscope Teamthat was some dirt on the surface of the tibia
- Bugscope Teamyup...that is the pollen basket
- StudentAre we far north enough?
- Bugscope Teamthe scooped out part on the tibia
- Bugscope Teamit is very smooth
- Bugscope Teamyou are doing a good job driving -- let's go a bit further north!
- 12:46 pm
- StudentWhere are we going?
- StudentCan we look at the wing?
- Bugscope Teamokay, the next joint up is the beginning of the tarsi
- Bugscope Teampreset 21
- StudentWhat is a hamuli?
Bugscope TeamThe little hooks are the hammuli. The hold the front and hind wings together so that they move as one wing.
- StudentWhat are those curved areas?
Bugscope Teamthose are the hamuli. They are hooks that hook the forewing and hindwing together
- StudentWhat are the little dots on the wing?
Bugscope Teammostly just dust
- 12:51 pm
- Bugscope Teamwe do see some more setae, or microsetae, on the surface of the wing
- StudentWhich preset holds the stinger?
Bugscope Teamno 12
- Bugscope Teamthe stinger is very hard to see
- Bugscope Teamthey don't always stick out
- Bugscope Teamnow you can see the tip of the abdomen, where the stinger is
- Bugscope Teamthe preset was centered on the stinger, and it was hard to distinguish from the surrounding area
- Bugscope Teamnow, to the right, we can see one of the combs on the bee's leg
- StudentWhat is an ovipositer?
Bugscope Teamthe ovipositor is what an insect uses to inject its eggs into the place where they will mature and hatch
- 12:57 pm
- Bugscope Teamso it is pointy, often, just like a stinger -- it is actually a modified stinger
- Studentdo workers have ovipositives?
Bugscope Teamyes workers do because they are females
- Bugscope Teamor technically not, really, since they are used only as stinger
- Bugscope Teamstingers
- Bugscope Teamthe queen is the only bee that will lay eggs
- Student what is the stinger made of?
Bugscope TeamThe stinger is made of insect cuticle, which is made of chitin
- Studentwe thought that only the queen bee layed the eggs?
Bugscope Teamthat is correct
- Bugscope Teamparasitic wasps will use their ovipositors and sting things like caterpillars to lay their eggs inside the caterpillar.
- Studenthow many bees in a average hive?
Bugscope TeamI found a reference that says 30,000 to 60,000 bees
- Bugscope Teamsometimes the cuticle is hardened with calcium
- Studentwhat does a stinger inject
Bugscope TeamA stinger injects a venom. The venom from a bee causes pain and swelling.
- 1:02 pm
- Bugscope Teamthis is the proboscis -- this is what the bee uses to collect nectar
- Bugscope Teamchitin is what insects' exoskeletons are made of, which is the same stuff as our fingernails
- Studenthow many bees does it take to pollenate?
Bugscope TeamIt takes a single pollen grain on a single bee to pollenate a flower
- Studenthow far does a bee have to travel to get nector
Bugscope TeamBees will forage for pollen and nectar in a 2 mile radius around the hive
- Student do the bees like to pollinate
Bugscope TeamIt is all they can do. They don't know how to do anything else other than tend the hive when they are young and forage for pollen and nectar when they are older.
- Studenthow many ifferent speacies are there
Bugscope TeamThere are nearly 20,000 known species of bees
- Studentwhat is the bee hive made out of?
Bugscope TeamThe beehive's internal structure is a densely packed matrix of hexagonal cells made of beeswax
- 1:09 pm
- Studentwhat do bees do when they're not pollenating?
Bugscope TeamA honeybee hive will have workers that do many different things. Some workers keep the hive clean, some take care of the baby bees, and some forage for pollen. When the foragers are not foraging, it is night time, and I think that is when they "sleep
- Studentis this the bees eye?
Bugscope Teamthe bee's compound eye is to the left. The bump to the right is one of its ocelli. An ocellus is a simple eye (1 of 3) used to help navigate
- Bugscope Teamthis is the eye, on the left, and on the right is one of the three ocelli - the simple eyes
- Student what does a simple eye do
Bugscope Teamsimple eyes help flying insects maintain their orientation with the sun and thus help them avoid getting lost
- Studentcan bees hear/
Bugscope Teamthey can sense vibrations with the tiny setae of their bodies. They do not have ears like we do though
- Studenthow do bees make theier hive?
Bugscope Teambees have glands on their abdomens, called mirror glands, that produce wax that they form into the cells that make up the hive
- 1:15 pm
- Studentwhat is the difference between a bee and a wasp?
Bugscope TeamWasps are thinner, can be aggressive, and interested in food and garbage. Bees are generally plumper, mild mannered and interested in flowers, not your lunch or garbage can.
- Studenthow long does a bee live?
Bugscope TeamA worker bee will live about a month
- Studentwhat are a bees enemies?
Bugscope TeamThere are many diseases and parasites like mites that can harm bees. There are also some beetles that can get into hives and eat the baby bees (larvae). There are some caterpillars that can destroy the wax in a hive. Many mammals, like rats, skunks, raccoons and bears will tear open and eat a bee hive.
- Studenthow do you tell the difference between a bee and a wasp
Bugscope TeamIn think the most obvious difference is the narrow 'waist' of a wasp compared to a bee
Bugscope TeamBees are very very hairy, while wasps are not. The textbook way is that bees have forked hairs all over their bodies, while the hairs on wasps are not forked.
- Studentwhat do bees eat
Bugscope Teambees eat honey and nectar
- Bugscope Teamantenna!
- 1:20 pm
- StudentHow do bees get there queen
Bugscope TeamBees feed some of the larvae different food. The differences in the food causes the bee larvae to grow larger and grow differently. These larvae that are feed the special food grow into queens.
- Studentwhat is the white spot on it's antenna
Bugscope Teamthat is a scale -- a feather-like component of the wings
- Bugscope Teamnectar is the sugary fluid plants produce to attract insects such as bees; the plants do this so that the bees will come and pick up pollen, which can then be transferred by the bees to other flowers, pollinating them
- Studentcan we see the top of the nob
- Bugscope Teamyou can drive there or go to preset no. 6
- Bugscope Teamthis looks like bamboo!
- Studentit looks like wood.
- Bugscope TeamCool!
- 1:25 pm
- Bugscope Teamthis is the tip of the antenna of this butterfly
- Bugscope TeamCate could not put the wings on or there would've been no room for anything else.
- Bugscope Teamthough i did put a piece of the wing on so you could see the scales
- Bugscope Teamwe are at the edge of the stub -- to the right is the end of the world
- Studentthank you
- StudentThank you!
- Studentits time for us to go home
- StudentThank You for answering our questions
- Bugscope TeamThank You for working with us today!
- Bugscope TeamHome? Already?
- Bugscope Teamthank you for all your awesome questions.
- Student thank you happy holloween
- Bugscope TeamThank you all
- Bugscope TeamWe appreciate getting to work with you.
- 1:30 pm
- TeacherThanks Scot, Cate and Annie We look forward to seeing the chat and pictures
- Bugscope TeamThank you too!!
- Bugscope Teamhttp://bugscope.beckman.illinois.edu/members/2009-076/
- Bugscope Teamgo to that link to find your images and chat from today
- Bugscope TeamSee you in a week?
- Bugscope TeamWe will try to find a better stinger...
Bugscope TeamHi Mrs Happnie!
- TeacherJave a great weekend! bye
