The Flammulated Owl (Otus flammeolus) is a small, cavity-nesting species that feeds on a wide variety of nocturnal arthropods (Marshall 1957, Johnson and Russell 1962, Ross 1969). Various studies throughout western North America during the breeding season have found species in the order Lepidoptera (moths and their larvae) and/or Orthoptera (crickets and grasshoppers) to constitute the majority of this owl’s diet, with Coleoptera (beetles), Dermaptera (earwigs), Araneae (spiders), Chilopoda (centipedes), and miscellaneous insects making up a smaller percentage (Goggans 1986, Reynolds and Linkhart 1987, Powers et al. 1996).
