Comments: S. cynipsea is by far the most commonly collected species in Switzerland ( Rohner et al. 2014, 2015). It occurs in great numbers on cow pastures throughout the season. Adults are attracted to fresh cow dung in particular. S. cynipsea has been widely used as model organism in evolutionary ecology and life history evolution, and is to date the best studied sepsid species ( Blanckenhorn 1997, 1999; Blanckenhorn et al. 2000).
