Prosternon tessellatum, the chequered click beetle, is a species of click beetle belonging to the family Elateridae.

Distribution

This species is widespread in Europe, in Asia, and in the Nearctic realm.[2][3]
Habitat

These beetles inhabit mountain areas, coniferous forests, dry forest edges and forest meadows, but also heathland, moors, dunes and gardens.

Description

Prosternon tessellatum can reach a body length of approximately 10–12 millimetres (0.39–0.47 in). These beetles have a hairiness blackish-brown pronotum and striped elytra, with paler silk-hairy gray-yellow to gold-shining stains.

They are rather similar to Agrypnus murinus, that is smaller.
Biology

Adults can be found from May to early August, feeding on flowers, shrubs and low vegetation.[4]

Larvae of this species live in tree stumps of conifers and in humus. They are predators and destroy cocoons of pine-tree lappet (Dendrolimus pini) and pine sawfly (Neodiprion).
