( Panzer , 1796)

Mordellistena neuwaldeggiana is a beetle fromthe sting beetle family . The genus Mordellistena is represented in Europe with three subgenera and over 170 species .

Notes on the name

The Beetle was described by Panzer in 1796 under the scientific name Mordella neuwaldeggiana . The description by Panzer contains the sentence: Habitat in floribus, Neuwaldegg ( Latin lives on blossoms, Neuwaldegg). The species name neuwaldeggiana refers to the place where it was found Neuwaldegg , which is now a district of Vienna . The species name brunnea is often found in the literature . It alludes to the body color (lat. Brunnea for brown ) and goes back to the description of the beetle in 1801 by the widely recognized authority Fabricius .

The generic name Mordellistena was defined by Costa in 1854 . The description of Mordellistena by Costa begins with Corpus magis compressum (Latin body rather strongly compressed), which explains the generic name. It derives from the generic name Mordélla and altgr. στενός “stenós” for “narrow, narrow”. Costa describes the beetle under the name Natirrica meridionale .

Three different views of the beetle

Characteristics of the beetle

The animal is solid yellow-red on the top and bottom. The body is strongly arched lengthways and slightly arched on the top side. The underside is compressed like a keel. The rear end is drawn out to a horny point. Measured without this tip, the beetle can reach a length of almost three to four millimeters.

The head is not flattened, but more or less arched and wider than it is long. It is stretched forward in the living state so that the mouthparts are clearly visible. However, as the dead beetles dry, it bends down. The upper jaws are broad, triangular and toothed at the tip. The edge of the back of the head between the eyes is relatively short compared to similar species.

The eleven-link antennae are thread-shaped and relatively long. Except for the lighter basal parts, they are a little darker brown than the body. The third antennae is at least as long as the second, not - as in Mordellistena humeralis - shorter. The fourth antennae is not weaker, but is as long and wide as the fifth and the following antennae. The last link of the four-part jaw palpation is ax-shaped in both sexes.

The pronotum is slightly wider than it is long. The front edge is obtuse in the middle, the sides are only slightly convex. Just before the back corners, the sides run parallel to each other. The back angles are almost right angled. In the middle of the posterior margin, the pronotum is extended backwards like a lobe.

The label is triangular.

The elytra are narrow. They do not end together rounded, but individually slightly tapered. They can get darker towards the tip.

The front and middle legs are delicate, their tarsi five-limbed. The penultimate tarsal limbs do not end cut or bilobed, but cut straight. The front hips are cone-shaped. The legs of the last pair of legs are strong. The rear hips form a large plate. The thighs are compressed, broad, almost elongated elliptical. On the underside they have a channel into which the back of the rails can be inserted. The rails are much narrower and shorter, hardly stronger than the first tarsal link. The notches on the hind legs are important for determining. Shortly before the end and parallel to it, there is a so-called apical notch and also two very sloping lateral notches on the rear rails. The notches are colored darker. The rear rails end with two thorns, the outer one is long, the inner one is short. These reach the middle of the width of the rails. The four-parted hind tarsi are also notched. The first hind artery link has three notches, the next two notches.

biology

The heat-loving species is found from April to September on sun-exposed forest edges and in clear places in deciduous forest. The beetles can be found there on flowers and herbs, preferably on umbellifers and daisy family , also on the plant genus silk . They have also been found in gardens, on rock heather, in vineyards and in floodplains. The females dig into rotten wood with the sting and lay the eggs there. The larva develops in thin branches or stems of the linden or other hardwoods ( poplars ).

distribution

The beetle's occurrence is limited to almost all of Europe and Turkey . In the north, the beetle is only found in part of the warmer southern provinces of Sweden . In the south, the distribution area reaches Spain , Italy , Greece and Turkey. However, the beetle is not found in all European countries. There are only old find data from Denmark . Evidence is missing from Great Britain , the Benelux countries , Portugal , Albania and European Turkey. In the east, the beetle reaches Ukraine , but there is also a lack of evidence in some parts of Eastern Europe. The species was reported as new from Estonia .
