Remarks.

Common and widespread species throughout the Western Palaearctic region (Yu et al. 2012); the most common hymenopteran found in European caves and artificial subterranean environments such as cellars (Novak et al. 2010). This species is a parasitoid of various caterpillar hosts (mainly Noctuidae and Geometridae), and females overwinter as adults (Constantineanu 1959, Yu et al. 2012).
