Longitudinal rows of pits are visible running the length of the elytra and densely scattered pits are obvious on the pronotum. The body is covered with a dense covering of black hairs which are noticeably longer than in most Elaterids. The legs are black, lightening towards the tips of the tarsi. The antennae are black and extend to the posterior edge of the pronotum.

Distribution – Two isolated population strongholds are apparent around the Lincolnshire/Cambridgeshire border and in Hampshire. Other scattered records from London, south Wales and Somerset.
Biology – Larvae are primarily associated with Birch (Betula spp.), Beech (Fagus sylvatica) and Hawthorn (Cratageus spp.), where they develop in rotten heartwood. Associations with other tree species are probable. Pupation occurs in autumn and the insect ecloses to overwinter as an imago within the pupa. Upon emergence the imagos can be recorded feeding at Hawthorn flowers.
Habitat – Ancient woodland pastures.
