Dorcadion scopolii

Pedestredorcadion scopolii

Dorcadion scopolii ( according to some authors Pedestredorcadion scopolii ) is a beetle of the family of longhorn beetle and the subfamily Lamiinae. The type is one of the many living on the ground longhorn beetles, the center of the distribution area is located in Southeastern Europe.

Remarks about the name

The species was described in 1784 by autumn under the name Lamia scopolii than 12 species of 37 genus. Autumn noticed: Under this name he is ( the beetle) sent me from Hungary, although in Scopoli I find the same same no description. The species name " scopolii " thus refers to entomologists Giovanni Antonio Scopoli.

The genus name " Dorcadion " ( AltGr. Δορκάς Dorcas Gazelle δορκάδιον dorkádion, Lugs ) expresses that it is smaller longhorn beetle species. Pedestredorcadion (Latin pedestris awarded by the legs because the similar Pedestredorcadion are pedestre red; synonym to Pedestredorcadion is Cribridorcadion ) is traditionally a sub-species of Dorcadion, which was later upgraded to the genus. The genus Pedestredorcadion in Europe is represented by over ninety species worldwide with over two hundred species.

Characteristics of the beetle

The Beetle achieved only a body length of 10 to 13 millimeters. The body is elongated oval and black, but ( Tomentierung ) appears because of the very short hair velvet gray with white stripes.

The head is tilted perpendicular to the body axis downwards. The mouthparts show almost vertically downwards, the last member of the pine fusiform button is pointed and not truncated obliquely. The first antennal segment is strongly built, the second antennal segment is short, as with most longhorn beetles, and the third smaller than the first ( Fig. 2). The rest of the 11 antennal segments taper increasingly outward. In females, the sensor does not reach the middle of the elytra, the male they exceed it slightly. The kidney-shaped sensor base comprising the compound eyes from the rear in such a way that on the end of the spacing of the bases of the two sensors to one another is greater than the distance between the inner edges of the eye ( inner edge in figure 4 marked with a green arrow).

An important taxonomic feature is that the front edge of the head capsule, the head shield (Fig. 4, right red margins ) is bent forward and so the plane of the base of the maxilla (Fig. 4, right yellow margins ) is.

Most striking are the white or yellowish, clear contrasting stripes. From top five are visible. The center runs from the forehead over the neck plate along the elytra seam to end of the body. Also located on each wing-cover two longitudinal stripes. The inner springs on the inner edge of the shoulder and parallel to the wing-coverts seam. The outer springs on the outside of the shoulder and is slightly bent parallel to the wing outline of the slab. The white -fringed margin of the elytra is under beaten. This cutoff edges is visible only from the side. In addition, the sensor base is ringed white and the eyes edged with white.

The pronotum is slightly pulled out behind the middle of the sides in a hump.

The elytra are fused together. At the back end, they are rounded oval together.

The legs are built tough. The five-membered tarsi appear quadrinominal ( pseudotetramer ) since the fourth link is hidden and very small between the lobes of the third member.


The species prefers warm temperatures and occurs in dry, open terrain. The adults feed on leaves and roots. They appear in late spring and can be found crawling along the floor. The larvae develop in the soil and feed on the roots of grasses. For the development they need a year.


The compact distribution area is located in South-East Europe. Its boundary is the north by the Czech Republic, Slovakia, and Ukraine, on the west by Hungary, Croatia and Serbia, in the south it reaches Greece and the East European countries bordering the Black Sea.
