Eburia quadrigeminata
Ivory-marked Beetle, Ivory-marked Borer
Eburia quadrigeminata is a North American longhorn beetle in the family Cerambycidae. Adults range from 12–25 mm in length and are attracted to ethanol-based baits, often captured in bait traps in substantial numbers. The species is widely distributed across eastern and central North America, with records from the eastern United States westward to Oklahoma. Larvae develop in sound, non-decaying hardwood, including timber.
Eburia stigma
Eburia stigma is a longhorn beetle in the family Cerambycidae, distributed across the Caribbean, Middle America, and North America. The species belongs to the tribe Eburiini within the subfamily Cerambycinae. Records indicate presence in the Caribbean region, Middle America, and North America, with museum specimens documented from the British Museum.

Ecyrus arcuatus is a longhorn beetle (Cerambycidae) described by Charles Joseph Gahan in 1892. The species belongs to the subfamily Lamiinae and tribe Pogonocherini. It occurs across parts of North and Central America, with documented records from the United States, Mexico, Guatemala, and Honduras.
Ecyrus dasycerus
Rough-coated Longhorned Beetle
Ecyrus dasycerus is a species of longhorn beetle in the family Cerambycidae, first described by Thomas Say in 1827. It is known from North America, with records from the United States and Mexico. The species exhibits two recognized subspecies: the nominate E. d. dasycerus and E. d. floridanus described by Linsley in 1935. Like other members of the subfamily Lamiinae, it is a wood-associated beetle whose larvae develop in dead or dying woody plants.

A longhorn beetle species in the subfamily Agapanthiinae, described by Fabricius in 1801. The species has been documented exhibiting death-feigning (thanatosis) behavior when disturbed. Observations suggest activity in summer months in North American grassland and woodland edge habitats.
Holopleurini
Holopleurini is a monotypic tribe of longhorn beetles (Cerambycidae) containing a single genus, Holopleura, and a single species, Holopleura marginata. The tribe is classified within the subfamily Cerambycinae. Information on this group is extremely limited due to its rarity and restricted distribution. The species appears to be endemic to a narrow geographic range in western North America.

Hylotrupes is a monotypic genus of woodboring beetles in the family Cerambycidae, containing only the species Hylotrupes bajulus. The genus is the sole member of the tribe Hylotrupini. The species has been introduced globally through timber trade and is recognized as a significant pest of structural softwood timber. Adults are active in summer months, while larvae develop slowly within wood.
