Species text
This is a small, metallic green, predacious fly, recorded from a wide range of wetland habitats including fens, damp woods and coastal localities. The larvae are probably semi-aquatic carnivores. It is widespread in southern England and Wales and described as scarce and very local in d'Assis Fonseca (1978). The status has been revised from RDB 3 (Shirt 1987). Falk & Crossley (2005) states that although a widespread species, it appears to be somewhat local, with about twenty known post-1960 sites. Falk & Crossley (op. cit.) also state that the primary management objective should be to maintain a high, stable water level at sites, retaining ponds or ditches as potential breeding locations, and performing any necessary vegetation clearance on rotation.
