About

The black-spotted longhorn beetle is found throughout most of the UK. They're usually seen in woodlands, or along hedgerows. The adult beetles often visit flowers to feed on nectar and pollen, particularly hawthorns and umbellifers. Female beetles lay their eggs on fallen dead wood, old stumps, or decaying trees. The larvae live beneath the bark, feeding on rotting wood. They can spend two or three years in this stage, before creating a little chamber of wood fibre in which to pupate. They pupate in late summer or early autumn, but the adults stay within their pupal chamber until spring.
