Module 5 - mouth parts

[Mellifera Crofter]

I'll be sitting Module 5 on Saturday, so I'm looking through some previous exam papers.

One of them has this drawing of honey bee mouth parts. Does anybody know what the bulge marked F is? The PDF is too big to upload here, so here's a link to Google Drive (https://drive.google.com/file/d/0BzRABt_Rp9a6TFU5cEVNOW56M0E/view?usp=sharing). I thought E points to a maxillian palp - so it's probably not that.

Im only guessing but would they be the Glosssa, I would be interested to know what the right answer would be for all parts, thanks.
I also found this if its any help. http://courses.biology.utah.edu/feener/5445/Lecture/Bio5445%20Lecture%2010.pdf

Thanks Greengage, the drawing of the honey bee mouth parts in your link is interesting because it gives a good idea of the position of some of the overlapping parts.

No - the glossa is the tongue. It's marked either L or B - who knows! L could be the salivary canal and B the glossa; or L could be the glossa and B the hair on the glossa.

I've not seen F drawn on any drawing before, and it's not on the drawing you've linked to either.

Oh - the other parts are (and correct me if I'm wrong):

H - mandible
G - postmentum
I - stipe
J - prementum
E - maxillian palp
K - galea of maxilla
C - labial palp
D - paraglossa
A - flabellum (or labellum)
L and B mentioned above; and
F - I don't know.

Lacinia

[Mellifera Crofter]

Thank you, EK! For some reason I thought the laciniae were the flattish flag part of the galea because the dictionary describes it as 'a long narrow inner lobe of an arthropod'. I now see that I actually do have a drawing showing a lacinia in my Celia Davis book. I've completely missed it. Thanks again,

PS - actually, on that link Greengage gave it says 'laciniae are lost', and I also read somewhere else that the maxillae are devoid of laciniae. So, do honey bees have them or not? Curious.

Thanks for the information, I would only have got one right, I have printed it off and added your answers for future reference, Best of luck with the exam.

[Mellifera Crofter]

Thanks Greengage. If you're interested in honey bee anatomy and all things bee-related (but not management or bee keeping) - the two Celia Davis books are really good.

John, I'm lost. That sounds very cryptic to me. Actually, that's quite good. I'll just imagine a meaning, like reading the I-Ching.

Sorry Kitta
It meant as a joke really
I keep chickens I know the basic biology and their illnesses that's about it
We had a dog I could tell he was ill and knew to watch for fleas or worms
I have bees but apart from their basic makeup and diseases I don't know much about their internal organs
So if someone becomes a vet they need to know everything about a dog biology but at the end of the day they still have to walk him like the rest of us

I know - I did understand that. Now I understand it all. I'll never know as much as a vet or an entomologist - but I'm learning, and like the vet walking his dog, I'll continue to inspect my colonies.
