|

|
The 3 to 4 mm large saproxylic wood-boring weevil Dryophthorus corticalis (family Curculionidae) is the only representative of the genus in Europe. Worldwide around 50 species have been described, most of them from the pacific islands from Hawaii to New Zealand, where they disseminate with driftwood. The thermophilic species occurs in forests of the lowlands. They develop in red-rot of fallen and standing deciduous or coniferous trees, e.g. oak (Quercus), pine (Pinus) and spruce (Picea). The species is rare and scattered in Germany. Whereas from the Northwest mainly old records are known, it is more regularly found in the upper Rhine valley and the Neckar basin. Dryophthorus corticalis is regarded as vulnerable (RL 3) (Bense, 2002). Rheinheimer/Hassler (2010) propose near threatened (RL V) as new classification. (CB)
