Guides
Anaglyptini
Anaglyptini is a tribe of longhorned beetles within the subfamily Cerambycinae. The tribe comprises at least 12 genera distributed across multiple continents, including Anaglyptus, Paraclytus, Cyrtophorus, and others. Members are generally small to medium-sized cerambycids, with some genera exhibiting remarkable ant-mimicry. The tribe shows notable diversity in the Neotropical and Oriental regions, with some genera extending into the Nearctic.
Elaphidion
Elaphidion is a genus of longhorned beetles (family Cerambycidae) in the tribe Elaphidiini. Species in this genus are primarily Neotropical and Nearctic in distribution, with significant diversity in the Caribbean region including Puerto Rico, the Virgin Islands, and Antigua. Several species have been described in recent taxonomic revisions, including E. michelii, E. mayesae, and E. antiguensis. Some species are attracted to fermenting baits and have been documented in bait trap studies.
Elytrimitatrix
Elytrimitatrix is a genus of disteniid beetles established by Santos-Silva & Hovore in 2007, previously treated as part of the genus Distenia. The genus contains approximately 50 described species distributed primarily in the Neotropical region, with one species, E. undata, occurring broadly across eastern and central North America. The group has undergone significant taxonomic revision, with many species described since 2007. Adults are attracted to fermenting baits and ultraviolet light, and larvae develop in dead wood of various hardwoods and pine.
Graphisurus
Graphisurus is a genus of longhorned beetles (Cerambycidae) containing five North American species. Members are medium-sized beetles with distinctive elytral patterning. The genus exhibits notable host plant fidelity, with individual species specializing on particular tree genera: G. triangulifer primarily on Celtis (hackberry), G. despectus on Carya (hickory), and G. fasciatus on Quercus (oak). Adults are typically nocturnal and attracted to lights.
Haplidus
Haplidus is a genus of longhorned beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Hesperophanini. The genus was established by LeConte in 1873 and contains seven described species distributed in North America. Species in this genus are associated with coniferous hosts, particularly pines. Haplidus testaceus, the type species, has been collected from dead Pinus edulis (Colorado pinyon pine) branches, suggesting larval development in dead or dying pine wood.
Judolia
Judolia is a genus of longhorned beetles in the family Cerambycidae, subfamily Lepturinae. The genus was established by Mulsant in 1863 and contains approximately 14 recognized species distributed across the Holarctic region, with representatives in North America, Europe, and Asia. Species within this genus are typically associated with coniferous and deciduous forest habitats.
Methia
Methia is a genus of longhorned beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Methiini. The genus was established by Newman in 1842 and contains approximately 40 described species distributed primarily in North and Central America, with some species extending into South America. Species within this genus are typically small to medium-sized cerambycids. Adult Methia have been documented as attracted to ultraviolet and mercury vapor lights, suggesting nocturnal or crepuscular activity patterns.
Opsimini
Opsimini is a tribe of longhorned beetles within the subfamily Cerambycinae. The tribe comprises four genera: Dicentrus, Europsimus, Japonopsimus, and Opsimus, with a total of nine described species. Most species are geographically restricted, with distributions spanning North America, Europe, and East Asia. The tribe is characterized by relatively small body size and reduced antennal length compared to many other cerambycine tribes.
Oxymerus
Oxymerus is a genus of longhorned beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Trachyderini. The genus contains ten described species distributed exclusively in the Neotropical region, ranging from Nicaragua and the West Indies south to Bolivia and Uruguay. Species within this genus are medium to large-sized, brightly colored, and diurnal. Oxymerus aculeatus is the most widespread species and has been detected in Florida, raising concerns about potential establishment in the United States.
Parelaphidion
Parelaphidion is a genus of longhorned beetles in the family Cerambycidae, subfamily Cerambycinae, and tribe Elaphidiini. The genus was established by Skiles in 1985 and contains two recognized species: Parelaphidion aspersum (Haldeman, 1847) and Parelaphidion incertum (Newman, 1840). Members of this genus have been documented in fermenting bait trap studies in the central United States, where they are attracted to both molasses/beer and red wine baits. The genus belongs to the diverse elaphidiine group, which is characterized by larvae that typically develop in dead or decaying wood.
Plionoma
Plionoma is a genus of longhorned beetles (family Cerambycidae) in the tribe Trachyderini, containing three species: P. basalis, P. rubens, and P. suturalis. Members of this genus are notable for their bright coloration, diurnal activity, and strong association with flowers. P. suturalis has been documented feeding on mesquite flowers and exhibits bimodal seasonal activity, with adults appearing in spring, disappearing during summer, and reappearing in fall. The genus occurs primarily in the southwestern United States and northern Mexico, with P. suturalis representing a significant northeastern range extension into Oklahoma.
Sternidius
Sternidius is a genus of flat-faced longhorned beetles (Cerambycidae: Lamiinae: Acanthocinini) established by LeConte in 1873. The genus contains at least 20 described species distributed in North America. Sternidius alpha, a broadly distributed and highly variable species, has been the subject of molecular studies revealing cryptic genetic diversity among color morphs previously treated as subspecies.
Xylotrechus
tiger longhorned beetles
Xylotrechus is a genus of longhorned beetles in the family Cerambycidae containing approximately 200 described species. Members of this genus are characterized by their elongated bodies, long antennae, and often striking color patterns. The genus includes economically significant species such as Xylotrechus chinensis (tiger longhorned beetle), which is a pest of mulberry and other fruit trees, and Xylotrechus pyrrhoderus, a grapevine borer. Several species have been documented as attracted to fermenting baits, making them accessible to collectors using molasses-beer or wine traps.
