Marsh Fly - Sepedon spinipes

The Marsh Fly (Sepedon spinipes), also known as snail-killing fly, belongs to the family Sciomyzidae of the order Diptera. The names marsh fly and snail-killing fly are used for all the flies in the family Sciomyzidae.
Sepedon spinipes is about 8 mm long. It has brownish body color, bulgy eyes, prominent forward-pointing short antennae, and bristles on the upper hind leg.
They are known as snail-killing flies, because their larvae parasite on Gastropoda (slugs and snails). The adult marsh fly feeds on dew and nectar.
