The genus Scolytus includes 13 species in Europe that live monogamous on hardwoods and with one species on softwood . They are weevils from the subfamily of the bark beetles (Scolytinae). Since they set up their breeding systems in the bark of the host trees, they are counted among the bark breeders. They carry the spores of the fungi (including Ophiostoma ulmi and Ophiostoma novo-ulmi ), which cause Dutch elm disease.
Generic description
The adults are between 1.5 and seven millimeters long. The eyes are kidney-shaped. The antenna lobe is large, broadly rounded and the antenna lobe seams are pointed towards the center. The pronotum is large and narrows in front. Its base and sides are edged. The wing covers run horizontally to the end. A wing cover crash is missing. The abdomen rises from the second sternite towards the end. The front rails are smooth on the outside and the tip is curved like a hook. The third phalanx is heart-shaped (bilobed). Between the male and female imago there is sexual dimorphism in the shape and hairiness of the head as well as cusps or marginal teeth of the abdomen.
