Notes

In limestone caves in Spain and the Netherlands, this species has been observed consistently, although often in low numbers between other more common species ( Selfa and Escolà 1991, Vergoossen et al. In press). Exceptionally, there is one observation under tree bark from Luxembourg, but the area consisted of a former slag dump with many little niches between the stones. This is similar to one observation we have of D. quadripunctorius under bark, which normally also prefers caves exclusively. These specimens were possibly disrupted or exceptionally choose other hibernacula in the direct vicinity of the caves.

Status: Confirmed.

Records: Belgium (2) *, France (1) *, Germany (1), Grand Duchy of Luxembourg (1) **, Spain (8), the Netherlands (11).

First record: May 1947 or 1948 ( Heinrich (1949 b), Germany).

Hibernacula: B (1), C (33), DT (1), U (1).
