  Night-stalking Tiger Beetles

  Omus is a genus of flightless, nocturnal tiger beetles (subfamily Cicindelinae) endemic to the west coast of North America. Members are uniformly dark-colored and characterized by reduced or absent hind wings, restricting them to ground-dwelling locomotion. The genus comprises at least five recognized species, including O. audouini, O. californicus, O. cazieri, O. dejeanii, and O. submetallicus. These beetles occupy diverse habitats from forest floors to upper salt marshes, with some species showing strong associations with specific plant communities.
