- Bugscope Team sample is in 'scope and 'scope is pumping down for today's session
- Bugscope Team we are having problems with the 'scope...
- Bugscope Team trying to figure out what's going on
- Teacher Hi Scot- Maddy here- Should students log in as guests?
- Bugscope Team they can log in as students or guests. sometimes student option isnt available
- Bugscope Team Some can login as students and some can login as guests, if the student login won't allow more to be added.
- Bugscope Team We're setting up the presets now.
- Teacher Okay- student option is not available- kids aren't here yet
- Bugscope Team We're running a bit late due to problems with the alignments on the ESEM. Feel free to watch us hunt around. :)
- Bugscope Team We apparently have a bug in the code that enables the student login. If that option doesn't show up, use the guest option. We can pass control to a guest if necessary.
- Bugscope Team Almost ready.
- Bugscope Team any idea what plant the bees go to?
- Student Rose
- Student violet
- Guest peony
- Bugscope Team Hello!
- Student Rose of Sharon
- Student sun flower
- Bugscope Team We're ready to roll. Take over.
- Bugscope Team Mrs Susi you are the Supreme Ruler
- Guest what is the glossa
- Bugscope Team the glossa is the tongue
- Bugscope Team we can see the tip of it now
- Bugscope Team Glossa is the name used for what we'd call a tongue.
- Bugscope Team it has a kind of plate-like shape
- Bugscope Team the glossa is protected by hardened covers that comprise the labrum -- that are called the labrum
- Bugscope Team because I'm sitting at the microscope, I can make some small changes in the focus and the area we're looking at more quickly
- Guest are these our bees
- Student what is the labrum
Bugscope Team it is a pair of what look like hardened triangular covers that protect the glossa
Bugscope Team it looks like a pair of scissors, kind of
- Bugscope Team the labrum is folded toward us at the top of this view
- Bugscope Team now it is to the left, and we are looking at an antenna
- Bugscope Team Scott just tweaked the focus for you on the antenna.
- Bugscope Team the antenna is covered with tiny setae and also what are called placoid sensillae
- Bugscope Team You can probably keep magnifying this. They are very interesting.
- Student what is this
Bugscope Team this is one of the antennae; we can see the segments
- Bugscope Team the antennae are covered with chemoreceptors that help the bee taste and smell the air
- Student why are there segments
Bugscope Team the segments will allow the antenna to move around or bend
- Bugscope Team their exoskeleton is like a suit of armor and needs segments to be able to move
- Student why is there hair
Bugscope Team The setae ("see-tee") are used by the bee to sense its surroundings. They are able to "taste" the air and objects in the environment by sensing chemicals. You can think of them like tastebuds.
- Student why are there craters
Bugscope Team the craters are another form of chemoreceptor, we think. they help collect scents from the air
Bugscope Team the craters are the things called placoid (which means 'like a plate') sensillae (which means they are sensory)
- Bugscope Team this is a foreshortened view -- we are looking down a long section of antenna
- Bugscope Team this is the compound eye!
- Bugscope Team you can see that it, too, is covered with setae
- Bugscope Team Just a quick note about how this works. When Scott makes a change locally, to focus or to move, those images do *not* show up in your database for later review. If you want to be able to save those images for later printing, etc., you should make a small change, such as moving a small distance or zooming in or out to trigger the saving of an image to our database.
- Bugscope Team a hairy eyeball!
- Guest why is there hair on the eye
Bugscope Team They are sensory too. They are used for sensing the surroundings, primarily movement - such as wind speed, when the eyes get near things, etc. - but may also be useful for thermal regulation.
- Bugscope Team having a compound eye means the bee can see around it better than if it had a single lens
- Student can they see colors?
- Bugscope Team also, if you had compound eyes, you would be able to sense motion much more quickly -- the bee's brain can sense changes in the visual field at a very high rate
- Student What are the Hexagons?
Bugscope Team those are the individual facets of the eye, called ommatidia
Bugscope Team They're actually more or less spherical, but because they get packed together, they assume a hexagon shape.
Bugscope Team Each ommatidia is a separate lense. On these bees, there are hundreds to thousands per eye.
Bugscope Team Oops. "Lens".
- Student how many lenses do they have
Bugscope Team probably 3 to 5000 per eye
Bugscope Team a dragonfly or large hornet can have 30,000 ommatidia per eye
- Guest what color are the bees eyes
Bugscope Team i think they are usually black. scot you saw them before they were coated, is that right?
Bugscope Team they are black or brown
- Bugscope Team bees have branched setae, and the bee people on campus tell us that bees are the only insects with branched setae
- Bugscope Team we cannot see ultraviolet without the aid of a blacklight
- Student why doesn't every lens have a hair
Bugscope Team likely it is not necessary to have a hair, or seta, at the corner of each ommatidium
- Guest can they see colors
Bugscope Team Yes. They can. In fact, bees can see colors people cannot see, particularly shades of violet called ultraviolet.
Bugscope Team In fact, many flowers that depend upon bees or moths to pollenate them have completely different patterns of color if you look at them using a camera sensitive to ultraviolet light.
Bugscope Team Some flowers even have "landing strips" that direct the bee to the source of nectar and pollen. In the process, the bee gets pollen all over its body which it then carries to the next flower.
- Bugscope Team this is the edge of the known world
- Bugscope Team busy bee
- Bugscope Team Mrs Susi do you know what kind of pollen this is?
- Student how many grains of pollen baskets can they hold
- Bugscope Team they eat nectar and pollen
- Student Where do bees put the pollen?
Bugscope Team Do you mean when they get back to the hive? If so, they use it as food for the lavae.
- Teacher My bees forage in the woods so it's hard to know
Bugscope Team it looks like they have a favorite kind of flower, right now
- Guest How do bees make pollen into honey?
Bugscope Team the nectar they eat gets stored in a special stomach compartment. They later spit up the nectar that was broken down into simple sugars into honeycombs. Some evaporation takes place and you get honey
- Student How old can the queen get?
Bugscope Team I think 2 years is average; I'll check'
Bugscope Team 1 to 5 years; some people say 3 to 4
- Guest how do they make honey combs
Bugscope Team they use their mouthparts, and they have wax glands that extrude or exude the wax
- Guest Whats the queens job??
Bugscope Team the queen's job is to lay eggs, perhaps as many as 2000 per day!
- Student How do the bees chose a new queen?
Bugscope Team when they need a new queen they give a female larva royal jelly
- Student is there a king bee?
Bugscope Team no. it is pretty much a matriarchal society
- Student what do male bees do
Bugscope Team they fertilize queen bees; I believe there are usually very few of them compared to the workers and drones
Bugscope Team drones are males, sorry
Bugscope Team The queen chooses when males should be around, too. They are used only for breeding. The males (drones) live for a very short time. They eat, mate, and die. That's about it.
- Student do they have any predetors
Bugscope Team bears, honey badgers, ants, other bees
- Student Why do they die when they sting?
Bugscope Team their stinger has barbs that gets stuck in mammalian skin. When they try to pull back after they have stung, it rips the stinger out and they bleed out
- Bugscope Team along the right side of the tip of the stinger we can see some of the barbs
- Guest Why do bees have stingers
Bugscope Team To protect the hive. While the western honeybee loses its stinger after stinging and dies, when the entire hive stings someting trying to steal honey (sorry, Pooh!) it is enough to drive the animal away and save the hive, despite some worker bee's deaths.
- Student how do make the hive?
- Guest which bees have stingers
Bugscope Team the queen and the workers; males (drones) do not have stingers. stingers in insects are modified ovipositors, for laying eggs, so it makes sense that males would not have them
- Student what is royal jelly?
Bugscope Team It is secreted from the glands in the hypopharynx of worker bees
Bugscope Team that is a gland in their mouth
- Guest are queen bees bigger???
Bugscope Team Yes.
Bugscope Team yes they are much bigger; when they get back to the hive the workers cut their wings off
Bugscope Team that is, the queen, when she is smaller and has wings, flies out to meet males bees, and becomes fertilzed; when she flies back she becomes more sedentary, does not go out, generally
- Student How do they find the hive?
Bugscope Team they have 'dances' that they use to signal to each other where food is with respect to the hive; they also have ocelli (simple eyes) on the top of their heads that help them maintain location information with respect to the sky -- to the sun
- Student why are they yellow and black?
Bugscope Team they warn other animals that they could be dangerous. there are bee mimics that use these colors even though they aren't dangerous, but it protects them from being eaten
- Student Does the bee have any other defenses other than the stinger?
Bugscope Team they can do things like surround an uninvited guest and kill it by making it too hot
- Guest whats that
Bugscope Team these are hamuli, which are little hooks that connect the fore- and hindwings for flight
- Student how many wings do they have?
Bugscope Team they have 2 pairs of wings- so a total of 4
- Guest are really disappearing
Bugscope Team yes it is kind of scary
- Student what are the hooks for?
Bugscope Team they function like clips to hold the wings together in flight
Bugscope Team so there are two wings rather than four, essentially, for flying
- Bugscope Team one of the presets shows, in comparison to this, hamuli that are clipped on
- Bugscope Team here we see hamuli actually being used
- Student are they disappearing because of CCD?
Bugscope Team yes and some people think one of the primary causes is nicotinamide-derived pesticides/herbicides
- Guest why do they dance
Bugscope Team The dancing is a form of communication. The dance informs the other worker bees where there is a source of pollen.
- Bugscope Team nicotine is from tobacco and is presumably what the nicotinamides are synthesized from
- Bugscope Team (I'm now SuperDaniel, just in time for the end of the session. *sigh*)
Bugscope Team Stupid keyboard.
- Teacher We have lunch now- Thank you so much for all your answers!\
Bugscope Team Thank You, Everyone!
Bugscope Team Thanks for participating! :)
- Teacher My bees here in MA are doing very well this year and all 4 hives survived the winter
Bugscope Team Nice.
Bugscope Team Whoops. Scott just killed your login.
