Contents

Distribution

This species is present in most of Europe (Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Russia, Spain, Sweden, Switzerland, United Kingdom), in the Near East, in the Nearctic realm, and in North Africa. [3]

Habitat

These flies mainly inhabit wooded areas, hedge rows, moist forests, wet meadows, parks and gardens. [4]

Description

Chloromyia formosa can reach a length of 7.3–9 millimetres (0.29–0.35 in) and a wing length of 6–7 millimetres (0.24–0.28 in). [4] Their body is elongated, the thorax is metallic green, the head is hemispherical without hair, while the eyes are quite hairy. Antennae are short, the first antennal segment is longer than the second. The legs are black, only the knees are yellow. The abdomen is flattened and broad.

An evident dimorphism exists between the males and the females of this species. In females the abdomen is blue-green with a purple sheen (depending on the light), while in males it shows a copper-green sheen. The female’s eyes are separated from each other. The wings are yellowish-brown.

Biology

Adults can mostly be encountered from April through August, feeding on nectar of flowers (mainly of Apiaceae species) and on pollen of Filipendula ulmaria (Rosaceae). [4] Between April and August these insects mate several times. The larvae develop in humus-rich soil, feeding on dead leaves and other decaying vegetal substances. [4] After reaching the final stage larvae overwinter.

Stratiomyidae Family of flies

The soldier flies are a family of flies. The family contains over 2,700 species in over 380 extant genera worldwide. Adults are found near larval habitats, which are found in a wide array of locations, mostly in wetlands, damp places in soil, sod, under bark, in animal excrement, and in decaying organic matter. The Stratiomyinae are a different subgroup that tends to have an affinity to aquatic environments. They are diverse in size and shape, though they commonly are partly or wholly metallic green, or somewhat wasplike mimics, marked with black and yellow or green and sometimes metallic. They are often rather inactive flies which typically rest with their wings placed one above the other over the abdomen.
