• Grylloblatta chintimini

  Marys Peak Ice Cricket, rock crawler

  Grylloblatta chintimini is a species of rock crawler (family Grylloblattidae) described in 2015 from Marys Peak in the Oregon Coast Range. It is one of the most recently described species in this relict insect order, bringing the total number of Grylloblatta species to 15. The species occurs in a restricted alpine habitat on persistent snowpack near the 1250 m summit. Like other grylloblattids, it is adapted to cold, moist environments and is considered a living fossil representing one of the most basal lineages of winged insects.

• Omus

  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.
