The Little Capricorn Beetle ( Cerambyx scopolii ), also Skopolis longhorn beetle , book Bock , Runzelbock or book Gemsbok called, is a kind from the family of longhorn beetles .
description
The beetle is solid black with very fine gray hairs. It has wrinkled elytra and reaches a length of 17 to 28 mm. Its pronotum and the elytra are conspicuously grained. The antennae of the males are significantly longer than the body, those of the females are roughly body length.
Occurrence
Its distribution area includes Europe , North Africa , Asia Minor and extends to the Caucasus . In Germany it is the most common species of the genus Cerambyx and can be found everywhere except in the extreme north-west.
The small oak buck is moderately warmth-loving and is therefore less common in the mountainous region . It cannot be found above 1,600 meters. In northern Europe it does not go further than southern Sweden . In Germany it is still common in many regions, but in some places it has shown a strong decline over the past 50 years.
Way of life
It is mostly found in June and July on flowering shrubs, on sunny forest edges or on fruit trees. He especially prefers elder , dogwood , hawthorn , umbelliferae and roses .
The larvae are polyphagous and live mainly in the arm-thick branches of deciduous trees. They first develop under the bark of various deciduous trees (e.g. oak , red beech , elm , walnut , plum and other fruit trees), later they go into the wood. They can reach a length of 50 millimeters. It takes two years to develop before pupating in a chamber in late autumn. The finished beetle then hatches in May. Occasionally it appears as a pest in orchards .
nutrition
The larvae feed on the wood of various deciduous trees, the beetles on pollen .
