The long-horn buck or Schneider Bock ( Monochamus sartor ) is a beetle from the family of longhorn beetles (Cerambycidae).

features

The agile climbers are characterized by long and strong legs. They are 21 to 35 millimeters long. The mouthparts point downwards, the eyes are well-edged and the first antennae are very strong. The antennae of the male are at least twice as long as the body, those of the females are slightly longer than this.

The pronotum is only slightly wider than the head, with a strong thorn in the middle on each side. The elytra are only slightly wider than the pronotum, but clearly set off by the shoulders. In the first third, in contrast to the other monochamus species, they are indented transversely. In the female, in contrast to the male, they hardly narrow.

In terms of coloration, males and females differ significantly. As with all monochamus species, only the antennae of the females appear curled by light hair on the base of the antennae, while those of the males are monochrome and dark. The elytra of the males are occasionally covered with indistinct, those of the female with many light hair spots, which are occasionally arranged in at least two interrupted bands.

The tailor's buck differs from the other Central European monochamus species by the uniform yellowish-white short hairiness of the tag (Fig. 2). In other species, they are hairless in a basal area or along the midline. From the species Monochamus rosenmuelleri , which is widespread from Northern Europe to Asia and in which the label is also completely hairy, it can be distinguished by the features at the end of the wing cover (Fig. 3). There the hair on the tailor's trestle is sparse and raised at an angle, the dots wrinkled. In Monochamus rosenmuelleri, on the other hand, the puncture towards the end of the wing cover is very fine and compact, and the hairs are white to yellowish and dense.

Other species of the genus

distribution

The tailor's buck is widespread in Central Europe, it also lives in northern southern Europe and is found in the north in Denmark , the Netherlands , in the south of Finland and on the British Isles . The species predominantly inhabits the coniferous forests of the foothills. The populations are falling sharply.

Way of life

The females usually lay their eggs in the bark of felled spruce , but occasionally also in pine or fir trees . The caterpillars initially develop under the bark and later switch to the wood. They penetrate deep into it, which is why they can cause considerable damage. The larva reaches a length of around 40 millimeters within at least three years. The beetles appear from July to September, they fly in the sunshine and can be found sitting on felled trunks.
