The peach jewel beetle ( Capnodis tenebrionis ) is a beetle from the family of jewel beetles and the subfamily of Chrysochroinae . The stocky beetle, which is rare in Central Europe, is easily overlooked despite its size between ten and 27 millimeters, as it is well camouflaged with its gray-black color.
Comments on the name and system
The species was described by Linnaeus in 1761 as Buprestis tenebrionis . The more detailed Latin description contains the comment Statura Tenebrionis ( Latin : figure of Tenebrio ). This explains the species name tenebriōnis (from the ending ancient Greek -ειδής -eidēs, "similar", and the generic name Tenebrio )
The genus Buprestis was broken down into many genera by Eschscholtz in 1829. The genus Capnodis includes the species whose shield is rounded at the back and whose last tarsal link is wider than it is long. The generic name Capnodis is from Altgr. καπνώδης kapnōdes, derived from smoky and means of dark color, dusted gray .
The genus Capnodis is represented by six species in Europe and eighteen species worldwide.
Description of the beetle
The head is broad with large, sideways eyes . The eleven-part antennae are widened inwards from the fourth part (butt-sawn). The upper lip is square and slightly cut out in front. The upper jaws are strongly curved and bidentate. The last two links of the jaw probe are spherical to ovoid. The end link of the lip switch is also spherical.
The elytra are roughly wrinkled with longitudinal rows of pierced points . Small, irregularly distributed circular white impressions may occur. The outer edges of the wing covers run parallel over half of the wing length. Then they narrow and taper off in a short, tail-like extension that ends in a truncated manner. The label between the bases of the two elytra is very small and rounded.
The pronotum is half wider than it is long and widened laterally in a heart-shaped manner. It bears the two characteristic features of the species. The dense puncture , which is coated with chalky secretion, rises bare, smooth, matt black, shiny surfaces (mirror spots). In the peach jewel beetle, these are only approximately symmetrical and show a strongly varying and confusing shape. In contrast to the similar species Capnodis cariosa, there are only two large, rounded spots at the base of the wing-coverts, which are approximately in front of the middle of each wing-cover. In the larger species Capnodis cariosa there is a third large mirror spot in the middle of the base. This encloses the deep, horseshoe-shaped dimple that is characteristic of the genus and lies on the base of the pronotum in front of the label (Fig. 5). It can be seen more clearly in Capnodis cariosa than in Capnodis tenebrionis . In addition, the remaining mirror spots in the larger species are arranged more in the form of a symmetrical figure.
The front hip cavities are open at the back, the spherical front hips are separated by a broad extension of the roughly dotted front chest (Fig. 7, right green). The middle hips (picture 7, right orange) are also spherical and a little further apart than the front hips. The rear hips (picture 7, right ocher) are broadly connected to the finer and more scattered dotted rear breast and are hollowed out at the back to partially accommodate the rear thighs. Only small parts of the mid-breast are visible. The legs are strong, all tarsi broad and five-limbed (tarsi formula 5-5-5). All of the tarsi are roughly the same length, the middle three are lobed at the bottom.
Occurrence
The heat-loving species lives in orchards, preferably on plum trees , and sloe stands . It is native to southern Europe and southern central Europe .
Way of life
The larvae develop under the bark in the bast on the root neck and in the stronger roots of stone fruit trees and sloes.
nutrition
The beetle eats wood from Prunus species
