Abstract: Sixty-four inactive nests of the solitary mud-daubing wasp Brachymenes dyscherus, reused by 5 inquiline species, were collected at Fazenda Santa Carlota, Cajuru, Sao Paulo, Brazil in 1995 and 1996.
Evolutionarily, miniaturization would be favored until the amount of food needed to produce an inquiline queen is less than that required for a host worker.

These inquiline crickets live in ant nests and exploit food resources in diverse ways (i.e., eating ant eggs, larvae, and nest debris; licking the surfaces of the ants' bodies; disrupting ant trophallaxis; or feeding via direct mouth-to-mouth transfer) [2-8].

We tested the hypothesis that Pachypsylla celtidismamma nipple gallmakers experience intraspecific competition and also interspecific competition (from an inquiline Pachypsylla species infesting their galls), and that competition would be reflected in negative relationships between gallmaker densities and individual performance.
Captured prey also constitute the resource base for a community of inquiline bacteria, protozoa, and invertebrates that inhabit the water-filled pitchers.
