The sealing Hairy neck Bock , also Green Schmalbock ( Lepturobosca virens , Syn. : Leptura virens ) is a beetle from the family of the longhorn beetle and the subfamily of the narrow blocks .
The greenish-gray color of its thick hairs gives the beetle the species name virens ( Latin ) 'greening' of its scientific name and the German name "Grüner Schmalbock". The genus name Lepturobosca refers to the genus Leptura , to which Lepturobosca was previously considered a subgenus, and contains βόσκω 'bósko' 'I graze' ( ancient Greek ).

Characteristics of the beetle
The 14 to 22 millimeter long beetle has the typical long, slightly curved shape of the narrow goats. It has long hairs everywhere, green or gray, the black body color appears at most at the joints of the exoskeleton.
The almost wrinkled dotted head with the brown mouthparts is inclined forward and downward. The long antennae typical of longhorn beetles are turned in on the top of the head in front of the rim of the eyes. The first antenna segment is very strong, the second almost ring-shaped and short. The other nine antennae are elongated and yellow at the base. The feelers appear conspicuously curled. You reach the last quarter of the elytra. The head is deeply indented lengthways between the deflection points of the feelers. The kidney-shaped compound eyes protrude strongly over the sides of the head. Their distance to the upper jaws (cheeks) is wide. Temples, however, are not developed, the head narrows behind the eyes directly to the neck.
The pronotum is barely longer than it is wide and strongly constricted in front, but the underside of the front chest between the head and front hips is not. The base of the pronotum is only slightly constricted, the posterior angles are not drawn out long. The pronotum is roughly dotted with small transverse wrinkles. Behind the front edge and in front of the rear edge it is indented transversely; it also has a deep and wide central furrow, which is not noticeable due to the hairiness (Fig. 1).
The elytra are densely punctured and wrinkled. They narrow rather uniformly behind the broad shoulders, more in the male than in the female. The tips of the elytra are individually rounded with a slight outer corner. The label stands out because of its particularly thick hair.
The front hips protrude downward in the shape of a cone. The tarsi are apparently four-limbed, since the small fourth limb is hidden in the bulge of the third limb.
biology
The larvae of the species develop in conifers, mainly Abies , Pinus sylvestris and Picea . The beetles can be found in Central Europe at higher altitudes from June to August on flowers ( Umbelliferae , Compositae , Sambucus racemosa , Veratrum album ) or on the breeding trees. The stenotopic species mainly lives in forests in the montane to subalpine zone.
In Northern Europe, the larva develops in fallen or felled trunks and tree stumps that are in the process of decomposition. The feeding tunnels are created in the deeper sapwood . The outer soft and rotting sapwood as well as the heartwood are avoided. Pupation takes place in late May and June in the sapwood. The adults appear at the end of June and in July.
distribution
The species occurs in Europe in almost all countries. Messages are missing in the west of Portugal , the Benelux countries , the British Isles and Denmark , southeast of the kind is Croatia , Greece , Macedonia and Albania and the European Turkey not reported. There are also no reports from the Republic of Moldova .
The distribution area can be divided into a northern area and a southern area. The northern area stretches from Scandinavia east to Siberia , Mongolia and Manchuria . The southern area is around the Pyrenees , Alps , the Balkans and the Carpathians .
