Nine visual or olfactory cues potentially used in host nest selection were presented in artificial burrows to cleptoparasitic Metopia campestris females flying at an aggregation of nests of digger wasps, Crabro cribrellifer. These flies are visually attracted to holes in the ground, with subsequent discrimination among nests mediated by chemical cues probably derived from the host female.
