Trichoferus
Trichoferus is a genus of long-horned beetles (Cerambycidae) established by Wollaston in 1854, containing at least 20 described species. Several species have become economically significant as invasive wood-boring pests, with Trichoferus campestris (velvet longhorned beetle) being particularly well-documented for its worldwide expansion through international trade. The genus includes both native and introduced species with documented associations with living trees, cut wood, and wood packaging material.
Trichoferus campestris
velvet longhorned beetle
Trichoferus campestris is a wood-boring longhorn beetle native to eastern Asia that has become an invasive species in North America and Europe. Adults are active from early summer, with peak abundance around 650 degree-days (base 10°C) in early July in Minnesota. The species is polyphagous, with documented reproduction on multiple hardwood species including Acer platanoides, Juglans nigra, and Malus domestica. Larvae develop in woody material and can complete development in cut branches.
Trigonarthris atrata
flower longhorn
Trigonarthris atrata is a species of flower longhorn beetle in the family Cerambycidae. It is found in North America and has been documented in the south-central United States, particularly in Oklahoma. The species is considered relatively uncommon and is attracted to sweet red wine and ethanol-based traps.
