Chloromyia is a genus of soldier flies in the Stratiomyidae family. Chloromyia flies are medium-sized, typically 7-10 mm in length. They feature a shiny metallic green or bronze thorax and an abdomen with a metallic blue-green or purple sheen, often more pronounced in females. The head is hemispherical with large, hairy compound eyes that are holoptic (touching) in males and separated in females, sometimes displaying iridescent hues (e.g., purple or green). 

The antenna are short and compact, consisting of three segments, with the third segment slightly elongated and clubbed, lacking a long arista. They are positioned above distinct white or yellowish frontal spots in some species. The legs are  long and thin, with the hind femora and tibiae often displaying characteristic dark banding or alternating light and dark segments, a key identifying trait. Wings are clear with a slight yellowish or brownish tint, held flat over the abdomen at rest. The scutellum lacks spines, aligning with typical Stratiomyidae features.

The adults are commonly found on flowers or low vegetation, feeding on nectar and pollen, thus aiding pollination. Larvae are semi-aquatic or terrestrial, often inhabiting moist soil, decaying organic matter, or near water bodies, where they feed on detritus or algae.
