Rhagium bifasciatum
Common throughout Britain from May-June.
They 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 ready to pupate after about two years.
The Adults feed on a wide variety of coniferous and broad-leaved trees
