Habitat

In SE Germany it is common in damp deciduous woodland on basic rocks and in former vineyards. Spelda (1999) quoted the edge of a wood on Muschelkalk in Baden-Württemberg at the western limit of its range. Numerous recorders have cited woodland including Quercus, Fagus and Pinus, as well as Alnus swamps. Under stones and bark.

In an important paper involving this species Voigtländer (1987) stated that it is hygrophilic and prefers warm calcareous sites, becoming increasingly synanthropic towards the northern part of its range, where it may occur on other soils and is found in gardens, parks, cemeteries, greenhouses and town ramparts. This applies to other peripheral records. Regarded as an stenotopic xerobiont woodland species with preference for xeric/mesoxeric meadows, fields and fallows in Saxony-Anhalt, Germany (Voigtländer 2011).
