The 7 to 16 mm timberworm beetle Lymexylon navale (family Lymexylonidae) is the only representative of the genus in Germany, with only five species worldwide. The female exhibits a black head and a red-brown pronotum and elytra. The elytra of the male are often blackened and the third article of the maxillary palps is enlarged and branched. The stenotopic and silvicolous beetles develop in ailing deciduous trees and felled timber logs, mainly oak. They are considered a serious pest of oak. The beetles can be found in old deciduous forests and on timber storage yards, where the swarm during the warm afternoon hours. Contrary to other Lymexylonidae they do not cultivate fungi in their burrows. In Germany, Lymexylon navale is recorded from most Federal States and is regarded as vulnerable (RL 3). (CB)
