Biology. Very rare species of steppes and sunny sites, bound to its host Lasioglossum pallens (Brullé) . Herrmann et al. (2003) described the biology both of the host and the parasite. The cleptoparasite as its host occur in spring (both males and females), and are recordable only during few days or weeks from March to May. Thus it seems to be rarer than it is.
