Category:Xenobiotic

The following taxa are xenobiotic. They form small colonies (up to a hundred individuals) in the nesting material or nest walls of their hosts, which are much larger than themselves. Their nests are well separated from the brood chambers of their hosts and they tend their own brood. They are dependent upon the hosts for nutrition and perhaps shelter and some xenobiotic species may solicit regurgitated food directly from a host worker or participate in food exchange (trophallaxis) between two host specimens.
