    Yes, I think so, DR. Photo 5 on this site, and Figure 2, B and C on this site shows the tongue stuck to the top fairly clearly. The larva decomposes, but the tongue remains stuck to the cell wall.

    Hi Kitta and GG
    The larva must be dying at a fairly late stage if it has a tongue (I guess)

    Yes, you're right, DR. To talk about a 'larva' (and I did say that) is wrong - it's 'pupa', as already mentioned in GG's title 'pupal tongue'. As we know, they only die after the cell is sealed and the larva has spun its cocoon. According to Celia Davis, the appendages pop out during the prepupal period (between day 9 to 13). So, it's the tongue stuck to the cell and the prepupa or pupa decaying around it.

    Got it Kitta
    So you think the poor old larva carries on developing to about day 12 then pegs out
    That would fit in with Les Bailey "infectious diseases of the honeybee"
    Apparently the bacteria doesn't do much in the gut
    It's when the larva pupates it can make its way through the gut wall into the haemolymph
    Poor old bee
    Odd that the tongue doesn't rot with the rest though
