Bucculatrix albertiella
Oak Ribbed Casemaker, Oak-ribbed Skeletonizer
A minute moth in the family Bucculatricidae, described by August Busck in 1909. The species is restricted to the west coast of North America and is associated with oak hosts. Larvae are leaf miners that produce distinctive ribbed cocoons.
Dicellophilus anomalus
Dicellophilus anomalus is a soil centipede in the family Mecistocephalidae, one of only four species in this family known from North America. First described by Ralph V. Chamberlin in 1904 from a single male specimen collected in Pacific Grove, California, this species was later transferred to the genus Dicellophilus by Filippo Silvestri in 1919. It is characterized by having exactly 41 pairs of legs in both sexes without variation, reaching up to 60 mm in body length. The species exhibits a restricted distribution along the west coast of the United States from Oregon to central California.
Feralia
Feralia is a genus of noctuid moths established by Grote in 1874. Species within this genus are late-winter to early-spring fliers, nocturnal, and readily attracted to lights. The genus includes Feralia februalis, a lichen-mimicking species narrowly endemic to the West Coast of North America and dependent on oaks as a larval food plant.
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.
