Biology. Based on Knutson (1973) laboratory studies; larvae are predator of a range of terrestrial snails ( Cochlicopa lubrica, C. minima, Discus rotundatus, Helicella itala, H. caperata, H. virgata, Eulota fruticum, Hygromia hispida and Oxychilus spp), then became saprophagous on dead snail host. Knutson (1973) described all larval stages and stated that puparium is formed outside the host snail, and represents the overwintering stage. This species is strictly univoltine (Knutson, 1973; Gaponov, 2016).
