Two-banded longhorn beetle

A large species of longhorn beetle that may reach 22 millimetres long and can be distinguished by the two prominent pale yellow bands on each elytron, although up to seventeen different patterns have been recognised. Like other longhorn beetles, Rhagium bifasciatum lays its eggs in dead wood, often using coniferous trees, where they bore deep, broad tunnels until they are ready to pupate after about two years.
