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).
