(B. J. D. Meeuse, The Story of Pollination....)

When the larvae hatch , they feed_on the beebread , although they also receive extra honey meals from their mother .

The larvae , kept warm by the queen , are full_grown in about ten days .

By the middle of the summer , many_of the larvae apparently receive such a good diet that it is `` optimal '' , and it is then that young queens begin to appear .

The nest itself , the structure that in some cases housed about 2000 individuals when the season was at its peak , is now rapidly destroyed by the scavenging larvae of certain beetles and moths .

Thus , the larvae of the intruder can develop at the expense of the rightful inhabitants and the store of beebread .
