Centrodera sublineata
flower longhorn beetle
Centrodera sublineata is a species of flower longhorn beetle in the family Cerambycidae. It occurs in North America and is one of approximately 15 species in the genus Centrodera. The species was first described by John Lawrence LeConte in 1862. Like other members of the subfamily Lepturinae, adults are likely associated with flowers where they feed on pollen and nectar.
Cortodera
Cortodera is a genus of longhorn beetles in the family Cerambycidae, subfamily Lepturinae, tribe Rhagiini. The genus contains approximately 21 described species, primarily distributed in North America. These beetles are associated with coniferous and mixed forest habitats. The genus was established by Mulsant in 1863.
Cortodera falsa
flower longhorn
Cortodera falsa is a species of flower longhorn beetle in the family Cerambycidae. It is found in Central America and North America. The species was described by John Lawrence LeConte in 1859. Like other members of the subfamily Lepturinae, it is associated with flowers.
Evodinus
Evodinus is a genus of longhorn beetles in the family Cerambycidae, subfamily Lepturinae, and tribe Rhagiini. The genus contains four recognized species distributed primarily in boreal and montane regions of North America and northern Europe. Members are associated with coniferous forests and are characterized by their distinctive elytral sculpturing.
Gnathacmaeops
Gnathacmaeops is a genus of longhorn beetles in the family Cerambycidae, subfamily Lepturinae. It was established by Linsley & Chemsak in 1972 and contains two species: G. pratensis and G. brachypterus. The genus belongs to the tribe Rhagiini, a group of flower-visiting longhorn beetles. Both species are native to Europe.
Grammoptera militaris
Grammoptera militaris is a species of flower longhorn beetle in the family Cerambycidae, described by Chevrolat in 1855. It belongs to the subfamily Lepturinae, a group commonly associated with flowers and decaying wood. The species occurs in North America and Middle America, with records from the United States and Mexico. Like other members of its genus, it is typically found in forested habitats.
Grammoptera rhodopus
Grammoptera rhodopus is a species of longhorn beetle (Cerambycidae) described by John Lawrence LeConte in 1874. The species belongs to the flower longhorn subfamily Lepturinae, a group characterized by adults that frequently visit flowers for feeding and mating. Available information on this species is limited, with only a single observation recorded in iNaturalist and minimal published biological data.
Metacmaeops
Metacmaeops is a genus of longhorn beetles (Cerambycidae) in the subfamily Lepturinae, tribe Rhagiini. The genus is monotypic, containing only Metacmaeops vittata, a species distributed in the eastern United States. Members of this genus are associated with mesic forest habitats and have been documented as flower visitors.
Pachyta
Pachyta is a genus of longhorn beetles (Cerambycidae) in the subfamily Lepturinae, tribe Rhagiini. The genus contains approximately 12 described species distributed across the Holarctic region. Members of this genus are associated with coniferous forests and share the characteristic short antennae and compact body form typical of the Rhagiini.
Pidonia densicollis
Pidonia densicollis is a species of flower longhorn beetle (subfamily Lepturinae) in the family Cerambycidae. It is distributed in the United States. The species was described by Casey in 1914. As a member of the Rhagiini tribe, it likely shares the flower-visiting habits common to many lepturines, though specific behavioral observations for this species are limited.
Piodes
Piodes is a monotypic genus of longhorn beetles (Cerambycidae) established by LeConte in 1850. It contains a single species, Piodes coriacea, distributed in the United States. The genus is classified in the subfamily Lepturinae and tribe Rhagiini.
Stenocorus copei
Stenocorus copei is a species of longhorned beetle in the family Cerambycidae, described by Linsley and Chemsak in 1972. It belongs to the subfamily Lepturinae and tribe Rhagiini. The species is considered rare and has been collected in high-elevation coniferous forests of the southwestern United States. Field observations indicate it is attracted to sweet red wine-baited traps hung in Gambel oak (Quercus gambelii) along the margins of alpine coniferous forest.
Stenocorus nubifer
Stenocorus nubifer is a species of longhorn beetle (family Cerambycidae) distributed across western North America. The species exhibits variable coloration, with individuals being either black or brown. As a member of the subfamily Lepturinae, it belongs to a group commonly known as flower longhorns, though specific floral associations for this species remain undocumented.
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.
