The Linde bark beetle ( Cryphalops tiliae ) is a weevils from the subfamily of the bark beetle (Scolytinae). Since it creates its breeding systems in the bark of the host trees, it is counted among the bark breeders.
features
The beetles are 1.1 to 1.5 millimeters long and have a medium-brown, cylindrical body. The pronotum is arched and at the front edge in the middle with four densely standing, protruding cusps, which are adjoined by a tapering cusp spot with four rows of small, approximately equal cusps arranged one behind the other. Seen from above, it covers the head. The elytra are at most twice as long as together wide and are covered with fine bristles. The antennae whip is four-parted, the antennae lobe has three straight seams.
distribution
The species is common in Scandinavia without Finland, England, France, Germany, Austria, Italy, former Yugoslavia, Romania, Hungary, the Czech Republic, Slovakia, Poland, Belarus, Ukraine and in the European part of Russia.
Way of life
The linden bark beetle occurs primarily on linden trees , but also on the hornbeam ( Carpinus betulus ) and the common beech ( Fagus sylvatica ). Usually it is an insignificant colonist in the bark and bast layer of dying twigs or the branches of older trees. The feeding pattern is a transverse or oblique one to four centimeters long, double-armed transverse duct ( mother duct ) with larval ducts going up and down.
