Calliopum is a genus of small flies of the family Lauxaniidae.
Most, but not all, are luscious black or metallic flies.[1] They are smaller than 5 mm and usually have iridescent eyes. Adults can be found from May until December in meadows and hedge rows.[2] The larvae may be phytophagous or saprophagous, mainly feeding on rotting vegetable matter or mining clover leaves.[3]
These species are present on most of Europe, in the eastern Palearctic realm, in the Near East and in North Africa.[4]
