Sinoxylon perforans

This is a thermophilic beetle of the family Bostrichidae. It has typical antenae and has two outgrowths at the end of the elytra. Its body is 5 to 8 mm long and has a cylindrical shape. The female lays from 20 to 30 eggs on the branches or tree trunks of oaks. The larvae then develop in the wood. Their galleries are filled with debris. The adults overwinter and in the spring adults feed on oak twigs (or on vine shoots). Due to the maturation feeding trees can be infected by pathogenic fungi. Univoltine species, one generation per year.
