Acanthocinus reticulatus

Long-horned beetle Acanthocinus reticulatus

Description

Acanthocinus reticulatus is a longhorn beetle from the family Cerambycidae, native to Southern and Central Europe, including parts of Russia. It primarily infests silver fir (Abies alba), where its larvae develop under the bark of dead or dying trees. Larvae feed between the bark and wood, creating tunnels filled with wood shavings and bark fragments. Acanthocinus reticulatus can be harmful, especially to weakened or dying fir trees, as its larvae feed between the bark and wood. This tunneling can interfere with the tree's nutrient flow, further weakening the tree. While it typically targets already stressed or dead trees, high populations of A. reticulatus in certain local areas could contribute to the decline of fir stands, particularly if the trees are already attacked by environmental stress or other pests. The species is nocturnal, with adults active from May to September and often hiding under bark during the day. While once more common, its presence is generally now limited due to the decline of suitable fir forests. It is generally rare to very rare species.
