''Coremacera marginata'' is a species of fly in the family Sciomyzidae, the marsh flies or snail-killing flies. It occurs in most of Europe and in the Near East. The adults grow up to long and can be encountered in grasslands and woodlands, feeding on nectar or sipping dew. This fly has a slender, dark greyish body. The prominent eyes are reddish. The brown-yellowish antennae are forward-pointing, with a hairy 3rd segment and a whitish arista. The dark grey wings are mottled with greyish spots. Larvae prey on several terrestrial genera of snails. ==Subspecies== *''Coremacera marginata'' var. ''marginata'' (Fabricius, 1775) *''Coremacera marginata'' var.
