The ore colored softwood jewel beetle ( Buprestis haemorrhoidalis ) is a beetle from the jewel beetle family . In Central Europe the species is only represented in the subspecies Buprestis haemorrhoidalis haemorrhoidalis .
The generic name Buprestis is taken from the ancient Greek Βουπρέστις bōūprestis , (among the Greeks a beetle, after which the cattle swell and die after consuming it ; formed from βοῦς bōūs "beef" and πρήθω prētho "I bloat"). The species name haemorrhoidalis is exceptionally not from Latin , but from Old Gr. αἷμα hāīma "blood" and ῥοή rhoē "river" derived and refers to the color of the beetle, which is also described in " ore colors ". The name coniferous jewel beetle expresses the connection of the species to coniferous wood.
Characteristics of the beetle
The body is dark copper or copper brown, more rarely dark green or blue-green, very rarely light copper. It does not shimmer in different colors. The yellow spots on the head, pronotum and underside are only visible from above on the side in front of the pronotum if they are sufficiently large there. The body is flattened and reaches a length of twelve to twenty-one millimeters.
There is a great risk of confusion between Buprestis haemorrhoidalis and Buprestis rustica . The ore-colored softwood beetle is longer, more arched and more narrowed towards the rear than Buprestis rustica .
The head is perpendicular to the body axis, the mouthparts point downwards. The jaw probes are four-part with an elongated egg-shaped end member, the lip probes are three-part with a truncated egg-shaped end member. There are mostly yellow spots on the front of the head. The large and flat eyes do not touch the base of the upper jaw . The eleven-part antennae are triangularly widened from the third part. They are pivoted away from each other in front of the front edge of the eyes. The yellow drawing of the head typically consists of several elongated vertical flaws, which are isolated (Fig. 4) or connected at the bottom by a transverse flaw, so that a crown-like pattern is created.
The neck shield is in contrast to Buprestis rustica less than twice as wide as long, less coarse and not as densely punctured , at the edge of the stippling is indeed tight, but not wrinkled. In addition, the pronotum is not clearly widened in front of the base as in B. rustica and then sharply tapered towards the front, but narrowing almost uniformly towards the front from the base itself. The sharp side edge descends in a straight line and disappears in the front third (Fig. 3). The lateral pronotum anterior corners are usually yellow, the size of the yellow area fluctuates considerably. The pronotum may occasionally have two or four dimples, more often two in front near the midline, less often two more near the base.
The wing covers are uneven. They are striped with dots. The spaces in between are not raised and have irregular rows of dots. The tip of the wing-coverts is mostly straight, the outer angle and seam angle are drawn out into a tooth. The label is very small and rounded.
On the underside of the body, the last segment (anal sternite) is colored yellow on the sides. As with all jewel beetles, the front breast is extended backwards, whereby the extension engages in a recess in the middle breast. An extension of the front chest to the front (chin band) is missing (Fig. 2). The legs have five-limbed tarsi .
biology
The development takes two years. It is made in fir , spruce or pine . The larvae are found in thin dead branches, in drying trunk wood of pine trees (Pinus) that has in some cases been dead for years and also in trees damaged by fire. In Finland, larvae can damage the species in wooden houses. In Greece, the beetle can be found in the fir and pine forests of the mountain regions, which differ significantly in climatic conditions. The larva was described in 1998.
The adults can be found on the nesting wood in Central Europe from June to August, in Greece from May to August.
distribution
The species is common in almost all of Europe except in extremely northern areas. She is missing in the UK . In various subspecies ( arakii , araratica , coreana , japanensis , sibirica ) the range extends to Japan. The species is also reported from North Africa.
