That's a sound natural history site but of no practical help to Nick.

Maybe you're right, perhaps the bit "At the end of autumn a number of eggs
develop into new queens and males, which leave the nest and mate. The new
queens seek out suitable places in which to hibernate, and the males and
the old colony (including the old queen) die" would be a bit beyond his
grasp, do you think? Or just yours?
