Notes

The species is autochtonous for Italy and is the most widespread of the genus. It lives in forests, but is also found in isolated dead trees. Usually it is gregarious, and it is found under the bark of various broadleaves such as hornbeam, chestnut, beech, poplar, oak, robinia, willow, elm, and fruits trees. It is rarely found in conifers such as fir and pine trees. Both larva and adults are often found with the Silvanidae Uleiota planata . The adult flies during the night ( Ratti 2007).
