https://en.wikipedia.org/wiki/Sciomyzidae Marsh flies are common along the edges of ponds and rivers, and in marshy areas. The adults drink dew and nectar. The larvae prey on or become parasites of gastropods (slugs and snails). The occasional sciomyzid attacks snail eggs or fingernail clams. Very little is known about the complete life cycle of these flies but most of the known larvae are semi-aquatic and some are aquatic. Other species have terrestrial larvae. Larvae mainly prey on non-operculate snails. Some species which prey on bivalves have larvae adapted to breathing under water. In some terrestrial species the penultimate larval instar emerges from the snail or slug it developed in. The last instar is then predatory on several snails.
