    Default Module 5 - mouth parts

    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. I thought E points to a maxillian palp - so it's probably not that.

    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.

    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 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.
