Snail-killing Flies
Sepedon is a genus of marsh flies in the family Sciomyzidae, commonly known as snail-killing flies. The genus contains approximately 70 described species distributed across multiple subgenera. All species share a distinctive life history: larvae are obligate predators or parasitoids of aquatic pulmonate snails. Adults are slender, elongate flies found in association with freshwater habitats. Several species have been investigated as potential biological control agents for snails that serve as intermediate hosts of schistosomes and other trematode parasites.
