Denops albofasciatus is a beetle from the family of the colored beetles (Cleridae). The rare species feeds on insects that live in the wood. It is strikingly colored and has an Australian doppelganger who is occasionally introduced into Europe.
The species name albofasciatus ( Latin albofasciātus = white banded) indicates the striking white horizontal stripes on the wing covers. The generic name Denops (from ancient Greek δεινός, deinós, terrible and οπς ōps, appearance) alludes to the large upper jaw. The species was first described by Charpentier in 1825 and placed in the genus Tillus . The genus Denops was not defined until 1829. Denops albofasciatus is common in Central and Southern Europe. The previously differentiated Denops longicollis (now regarded as a synonym) lives in the Canary Islands .
Body features
The body is elongated and cylindrical. It reaches a length of six to ten millimeters. The front body is hairy long protruding.
The head is remarkably wide, wider than the pronotum and as wide as the elytra . It is finely sculpted in a grainy manner. The eyes are far in front of the head. The antennae have eleven links, the first four links are cylindrical to slightly conical, the following ones are pressed flat and sawn on the inside. The upper lip ( labrum ) is slightly outlined in front. The upper jaws ( mandibles ) are strong, with a sharply curved tip and two teeth on the inside. The jaw probes are four-part, the lip probes are three-part. Both are thread-like with cylindrical links, the end link is not ax-shaped.
The pronotum is longer than it is wide and slightly behind the front edge and narrowed sharply in front of the rear edge. It has an unrimmed side edge, the top is slightly wrinkled. Like the head, it is rust-red.
The wing covers leave the last two to three parts of the abdomen uncovered. Although they are finely haired, they appear shiny, rows of dots are missing. The basic color is black. They are indistinctly reddish on the shoulders. A wide, sharply demarcated yellowish-white band runs about halfway across the elytra.
On the underside of the body, some important characteristics for the taxonomic classification are visible. Six segments can be seen on the abdomen. The front hips are approximated, the rear hips are broadly separated. The front hip cavities are completely closed on the inside and outside, but open at the back. The legs are not particularly strong. The brown tarsi are long and clearly five-limbed, the basal limb is no shorter than the second limb. The first four links are enlarged like a lobe on the underside. The claws are two-toothed on the inner edge.
The Beetle has a doppelganger native to Australia and New Zealand, which occasionally occurs in Europe due to the global turnover of goods. A reliable distinction between the two types is possible based on the length of the temple. It is longer than the eye diameter in Denops albofasciatus , but shorter in the doppelganger Paratillus carus .
Way of life
The warmth-loving species is classified as a "waste wood colonist" and a "landscape-ecologically relevant species". In Central Europe it is mainly found on sun-exposed forest edges and in vineyards. The larva and adult animal predatory on other insects and insect larvae, mainly borer beetles . This behavior is especially in crops of figs , olives , pistachios , carob trees and wine welcome. The larvae feed on the larvae of drill beetles such as Xylopertha retusa . Presumably the food spectrum is larger, longhorn beetles and jewel beetles are also mentioned.
distribution
The species is native to southern Europe and North Africa, but is rare. It is very rare in Central Europe, but it can radiate from southwest Europe to the Rhine area and from southeast Europe to Austria and Bavaria. In Central Europe it was found on oaks and vines, each with an infestation by Xylopertha retusa , in the Mediterranean area it is also found in the wood of other useful plants.
Systematics
Traditionally, two species were distinguished in the genus Denops , until it was shown in 1985 that Denops longicollis is actually a synonym for Denops albofasciatus . Both differ only in slight color variations.
