Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: a mild-temperate species found on more or less smooth bark, especially of Fraxinus ornus, with a single record from a very rainy area of the Eastern Alps (Italy).
