TRICHOFERUS CAMPESTRIS

VELVET LONGHORNED BEETLE

Trichoferus campestris, the velvet longhorned beetle, is a species of long-horned beetle in the family Cerambycidae. It is native to the southeastern palearctic, from Japan through to Armenia and southeastern European Russia, and is an invasive species in North America. The velvet longhorned beetle has begun to expand its range within Europe as well, spreading west. Trichoferus campestris is a member of the Cerambycinae, a large subfamily (more than 11,000 species) within the Cerambycidae. Members of this subfamily are generally characterized by their prognathous head with truncate terminal palpomeres, antennae borne on raised tubercles without a distinct club, absence of lateral pronotal carinae, and short broad mandibles.

It is native to the southeastern palearctic, from Japan through to Armenia and southeastern European Russia, and is an invasive species in North America. The velvet longhorned beetle has begun to expand its range within Europe as well, spreading west.

Male velvet longhorn beetles are 9.6–18 mm long, while females are 15.6–18.9 mm long. The entire body is a uniform brown-black with a golden pubescence and sporadic long hairs extending past the pubesence. Antennae are slightly shorter than or as long as body length in male, and shorter than body length in females.

Adult beetles do not feed, but the larvae feed on and develop within the trunk or large branches of a very wide range of broadleaved and coniferous trees, other woody plants and can also

develop in dead or dry wood. Trichoferus campestris has a known host range of about 40 genera of coniferous and deciduous trees, and this is likely to increase in the future, as more records are published.

It is only the adults that are likely to be seen, as eggs, larvae and pupae are all concealed in tunnels within the wood, but descriptions of all life stages are provided for completeness.
