Notes

The species lives from the plains to the mountains, but is also found in urban areas. The larva develops under the bark of broadleaves such as oak, beech, elm, poplar, and hornbeam trees, and is rarely in conifers such as fir and pine trees. The adult appears from the end of April to July ( Ratti 2007).
