These pictures show a female of Tragosoma depsarium (Linnaeus, 1767). Tragosoma depsarium is a Holoarctic species. In the Palaearctics it lives in the coniferous forests of Europe and Siberia. In Europe it reaches the Pyrenees in the SW and the mountain Olympus (Greece) in the SE. In Central Europe, however, it certainly belongs to the rarest longhorn beetle species. Tragosoma depsarium develops in Pinus spp. and sometimes also in Norway spruce (Picea abies). Larvae of Tragosoma depsarium feed primarily in the decaying sapwood of dead, fallen trunks, and occasionally in old stumps (cf. Figures 1 - 3). The development period lasts at least three years. Pupation takes place in the wood and adults appear from the end of June to August (middle of July to August in Central Europe) and are active during the night.

Body length: 16 - 35 mm
Life cycle: > 3 years
Adults in: June - August
Host plant: Pinus, Picea abies
Distribution: Holoarctic species

The beetle in these pictures was reared from a larva collected in a dead fallen trunk of Picea abies.

NORTH AFRICA - MO (Western Sahara) AFR

As Jean-Claude Ringenbach reports numerous males of Polyarthron pectinicornis were attracted to light traps in Ghat (Libya) in the last days of August following a substantial rainfall earlier in the month. Females did not come to light and consequently were difficult to find. Two females were found drowned in a swimming pool.
