Black and yellow longhorn beetle, Rutpela maculata.
These beetles are usually found in areas close to woodland, where there is plenty of dead wood for their larvae to feed on. They have long antennae but no horns! Females lay their eggs on fallen trees and branches, or rotting stumps. The larvae live within the wood, feeding on it, for two or three years which is why it’s so important to keep piles of rotting wood around.
