Coremacera marginata is a species of fly in the family Sciomyzidae, the marsh flies or snail-killing flies.

Subspecies

Subspecies include:[1]

Coremacera marginata var. marginata (Fabricius, 1775)
Coremacera marginata var. pontica Elberg, 1968

Distribution and habitat

This species occurs in most of Europe and in the Near East.[2] These flies can be encountered in grasslands and woodlands,
Description

The adults of Coremacera marginata grow up to 7–10 millimetres (0.28–0.39 in) long. These flies have 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.[3][4]

Adults feed on nectar or sipping dew. Larvae prey on several terrestrial genera of snails.[5]
