Biology. In laboratory, Knutson et al. (1975) studied and described all immature stages, and provided details on larval biology. The larvae are semi-aquatic predators, attacking principally freshwater snails such Lymnaeidae living on the wet edge of aquatic habitats and also their egg masses (Knutson et al., 1975; Gaponov, 2016). Pupariation takes place outside of the snails on the wet margin of aquatic habitats or soil, and represents the overwinter stage (Knutson et al., 1975). This species is multivoltine (Knutson et al., 1975; Barendregt, 2014).
