Chalcophora mariana
Flatheaded pine borer
With its length of 21 to 32 mm, the pine borer is one of the largest species of the jewel beetles (family Buprestidae) in Central Europe. The larva is white, up to 70 mm long, legless. The species develops for 3–6 years in recently dead trunks and stumps of pine. Adults are active from May through July. During warm sunny days they are observed mainly on pine stumps in clear cut areas. Females oviposit eggs in bark crevices of stems or stumps. Larvae hatch after 2 weeks and bore galleries of up to 15 mm wide. Adults emerge through exit holes of 1.0 × 0.5 cm in size. It is most frequently found in larger pine forests. In Europe two similar species occur only in southern areas: Chalcophora intermedia and C. detrita.
