, sometimes called the two-banded longhorn beetle
, is one of the commonest longhorn beetles
and the Caucasus
, although it is absent from the far north-east of Europe and some offshore islands
, such as Malta
. It may reach 22 mm
long and can be distinguished by the two prominent pale yellow bands on each of the elytra
, although up to seventeen different patterns have been recognised .
Like other longhorn beetles, R. bifasciatum lays its eggs in dead wood, mostly of coniferous trees, where they bore deep, broad tunnels until they are pupate after about two years . The adults feed on a wide variety of coniferous and broad-leaved trees .
