Last night I caught a hive of paper wasps while they were sleeping. Its a small hive, only containing 11 adult females, but each cell has either an egg, larva, or pupa in it I've kept wasps before, I even have a few steel-blue cricket hunters and a cicada killer, but I've never maneged to catch an entire hive before. I've been feeding the adults on fruit juice, and giving them insects for them to feed to the larvae. Adults in the wild eat nothing but nectar (and people's soda). They kill other insects, dismember them, and chew them into a pulp to be fed to the larvae. So far mine have completly dismembered a robber fly and several grasshoppers.
