A medium-sized (7-12mm), black and yellow longhorn resembling a small, squat Rutpela maculata. It is frequent in Wales, south-west, and the Surrey/West Sussex area with more scattered records extending to north Scotland. However, it rare or absent over much of central and eastern England, suggesting it prefers damper climates.
The larvae develop in the wood of various broadleaved and coniferous tree species, typically in exposed roots of fallen trees, and take two years to develop. Adults fly from May until Augusts and feed on a variety of flowers including Bramble, umbellifers and buttercups…Steve Falk
