Bionomics. Species belonging to Xenopygus have been frequently found in carrion, dung and decaying fruits (Irmler 1982; Navarrete-Heredia et al. 2002), also in leaf litter in the Eastern Cordillera of Colombia (Gutiérrez & Chacón 2006). Xenopygus analis was reported as predator of both larvae and pupae of Anastrepha spp. ( Diptera: Tephritidae) (Navarrete-Heredia et al. 2002), also from ant nests (Gutiérrez & Chacón 2006).
