Athoplastus rainieri
Athoplastus rainieri is a click beetle (family Elateridae) endemic to the Cascade Range of Washington State. Originally described by Van Dyke in 1932, it was transferred to the genus Athoplastus by Etzler & Johnson in 2018. The species is known from very few specimens and remains poorly documented in the scientific literature.
Melanoplus oreophilus
Mount Hood Short-wing Grasshopper
Melanoplus oreophilus is a spur-throated grasshopper species endemic to the Mount Hood region of Oregon. The species is characterized by reduced wing development, a trait reflected in its common name. It inhabits high-elevation alpine environments and has a restricted geographic range.
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.

Cascade Timberline Grasshopper
Prumnacris rainierensis, commonly known as the Cascade Timberline Grasshopper, is a species of spur-throated grasshopper endemic to the Pacific Northwest United States. The species is distinguished by its association with high-elevation timberline habitats, particularly in the Cascade Range. It belongs to the subfamily Melanoplinae, a diverse group of grasshoppers often associated with montane and alpine environments.
