oregona
Diplocheila oregona is a species of ground beetle in the family Carabidae. It is found in western North America, ranging from Nevada and Utah northward to British Columbia and Manitoba. As a member of the genus Diplocheila, it belongs to a group of ground beetles adapted to moist riparian and shoreline habitats.
Diplous
Diplous is a genus of ground beetles in the family Carabidae, tribe Patrobini. The genus contains more than 20 described species distributed primarily in boreal North America and Asia. North American Diplous species form a monophyletic group based on morphological and molecular evidence. These beetles are associated with riparian habitats in northern forested regions.
Dorytomus hirtus
Shaggy Weevil
Dorytomus hirtus is a weevil in the family Curculionidae, commonly known as the Shaggy Weevil. The species was described by LeConte in 1876 and is distributed across northern North America, with records from western Canada including Alberta, British Columbia, and Yukon Territory. As a member of the genus Dorytomus, it belongs to a group of weevils associated with woody plants, particularly willows and poplars. The specific epithet "hirtus" refers to the hairy or shaggy appearance characteristic of this species.
Dyschirius pilosus
Dyschirius pilosus is a small ground beetle in the subfamily Scaritinae, described by John Lawrence LeConte in 1857. The specific epithet "pilosus" refers to hairiness, a trait common among members of this genus. Like other Dyschirius species, it is likely associated with moist or riparian habitats where it preys on small invertebrates. The species has been documented across North America, with records from both Canada and the United States.
Elaphrus lecontei
Elaphrus lecontei is a species of ground beetle in the subfamily Elaphrinae, described by Crotch in 1876. The genus Elaphrus comprises true ground beetles that are frequently mistaken for tiger beetles (Cicindelinae) due to their similar appearance and behavior. These beetles are known for their metallic coloration and preference for moist, sandy habitats.
Elaphrus lindrothi
Elaphrus lindrothi is a species of ground beetle in the subfamily Elaphrinae, described by Goulet in 1983. It belongs to a genus known for species that closely resemble tiger beetles (Cicindelinae), often leading to misidentification by collectors. The species is native to the United States and is part of the North American fauna of Elaphrus, a genus of true ground beetles (Carabidae) with distinctive morphological adaptations.
Ellipes minuta
Smaller Sand Cricket
Ellipes minuta, commonly known as the Smaller Sand Cricket, is a species of pygmy mole cricket in the family Tridactylidae. This small orthopteran is adapted for burrowing in sandy substrates, with modified forelegs for digging. The species occurs across a broad geographic range including parts of North, Central, and South America. Like other members of the genus Ellipes, it inhabits moist sandy areas near water bodies where it can burrow and feed.
Ellipsoptera blanda
Sandbar Tiger Beetle
Ellipsoptera blanda, commonly known as the sandbar tiger beetle, is a species of flashy tiger beetle in the family Cicindelidae. The species is found in North America and belongs to a genus characterized by relatively large eyes, long legs, and ecological specialization for sandy and saline habitats with sparse vegetation. Like other members of Ellipsoptera, it inhabits extreme substrates including river sandbars and coastal environments.
Enaemia atrolinea
Enaemia atrolinea is a moth species in the family Lacturidae, known from the southwestern United States. It has been documented in New Mexico, where it occurs in riparian and mixed conifer forest habitats. The species is characterized by orange coloration and is active during late summer.
Erioptera
Erioptera is a genus of crane flies in the family Limoniidae, established by Meigen in 1803. The genus contains multiple subgenera and species distributed across temperate regions including North America, Europe, and Asia. At least one species, Erioptera squalida, has been documented as a root-piercing insect with specialized spiracular structures for accessing plant root gas spaces.
Erronus rivalis
Erronus rivalis is a species of leafhopper in the family Cicadellidae, described by Hamilton and Zack in 1999. It belongs to the subfamily Errhomeninae, a group of relatively primitive leafhoppers. The species is known from Montana, where it has been recorded in association with riparian or stream-side habitats, as suggested by its specific epithet 'rivalis' (meaning 'of a brook' or 'rivaling').
Eubriinae
Eubriinae is a cosmopolitan subfamily of water penny beetles (Psephenidae) comprising approximately 15 genera and 144 species, with greatest diversity in Asia. Adults are distinguished by a convex dorsal body form, truncate or emarginate anterior pronotum with exposed head, non-tapering maxillary palpus apex, and five abdominal ventrites. Larvae are aquatic and exhibit a metapneustic respiratory system with spiracles positioned near the bases of paratergites VIII. The subfamily exhibits nearly worldwide distribution except Antarctica and some oceanic islands including New Zealand.
