The label with the hairless spot

The baker Bock or spotted longhorn Bock ( Monochamus galloprovincialis ) is a beetle from the family of longhorn beetles (Cerambycidae).

description

The animals become 12 to 25 millimeters long, depending on the development conditions for the larva. The body is cylindrical and black. The head drops vertically so that the mouthparts point downwards. The eyes are so deep that they are almost split in two. The long and strong legs identify the beetle as an agile climber. The length of the front legs of the males, with their function of holding the female during mating, is particularly striking. The pronotum appears almost square from above and has a blunt thorn on each side. The first link of the antennae is strong and noticeably truncated. The antennae of the male are more than twice as long as the body and are a solid dark brown, those of the female are also longer than the body, but they appear curled up due to the light hair on the base of the antennae. Males and females of one species are therefore different in color than males and females of different monochamus species among themselves. Characteristic of the species is a hairless spot in the middle in front of the otherwise dense, light brown hairy scutellum .

The other monochamus species are very similar to M. galloprovincialis . The only difference is that with others the label is either completely hairy or instead of a point a longitudinal stripe is hairless.

Occurrence

They live mainly in the Mediterranean region ( southern France ), but occur sporadically in central and southern Germany . They live in pine forests .

Way of life

The beetles feed on the bark and shoots of young twigs. The larvae develop in pines and cause damage there.
