Stenocorus vestitus
Flower longhorn
Stenocorus vestitus is a species of longhorn beetle (family Cerambycidae) found in North America. The species exhibits sexual dimorphism in coloration: females are black while males are brown, a pattern shared with the congeneric Stenocorus meridianus. Adults are attracted to ultraviolet light and have been documented visiting fermenting bait traps. The species belongs to the subfamily Lepturinae, whose members are commonly known as flower longhorns.
Stenocorus vittiger
Stenocorus vittiger is a species of longhorn beetle in the family Cerambycidae, subfamily Lepturinae. It is characterized by a brown pronotum bearing four black longitudinal stripes, a pattern shared with the related species Analeptura lineola. The species occurs in eastern North America, with records from Canada and the United States.
Stenodontes
Stenodontes is a genus of longhorn beetles (family Cerambycidae) in the subfamily Prioninae, tribe Macrotomini. The genus was established by Audinet-Serville in 1832 and contains three recognized species: S. chevrolati, S. damicornis, and S. exsertus. These are large, robust beetles typical of the prionine group, with larvae that bore into wood.
Stenodontes chevrolati
Chevrolat's tropical long-horned beetle
Stenodontes chevrolati is a species of long-horned beetle in the family Cerambycidae, subfamily Prioninae. It is one of the largest cerambycid species in North America, with males reaching substantial size. The species occurs in the Caribbean and southern North America, where adults are attracted to lights and have been documented in oak woodland habitats. Larval development occurs in living oak trees, with adults emerging after several years of subterranean feeding on roots.

Sternidius alpha
Alpha Long-horned Beetle
A longhorn beetle species in the family Cerambycidae, first described by Say in 1827. Exhibits multiple color variants across its broad North American range, which led to the description of several subspecies later synonymized under the current name. Molecular analysis of the cytochrome oxidase I gene has revealed three distinct clades among color morphs, suggesting potential cryptic diversity. The species remains taxonomically unsettled pending further study of additional color morphs from different localities.

Specimens are typically collected by beating vegetation, particularly in association with woody plants such as New Mexico locust (Robinia neomexicana). The specific epithet "incognitus" (Latin for unknown or unrecognized) likely refers to the species' cryptic nature or delayed recognition.
Sternidius mimeticus
Sternidius mimeticus is a small longhorned beetle (Cerambycidae: Lamiinae) described by Casey in 1891. The genus Sternidius has undergone taxonomic revision, with species formerly synonymized under Sternidius alpha later revalidated. This species is part of a group of small cerambycids commonly encountered by collectors beating vegetation in western North America. Specimens are typically pointed rather than pinned due to their small size.
