Coelopsinae

Coelopsinae is a subfamily of flies belonging to the family Lauxaniidae. These flies are relatively small and generally brown or black in coloration. They are found in various parts of the world, with a notable distribution across the Old World tropics and subtropics, though some species extend into temperate regions.

The larvae of Coelopsinae are saprophagous, meaning they feed on decaying organic matter. Their exact ecological roles are not extensively documented for all species, but like other lauxaniids, they are presumed to play a part in decomposition processes. Adult flies are often observed on vegetation, in damp woodlands, and near decaying plant material. Their feeding habits as adults are not as well-studied as their larval stages, but they are believed to feed on plant juices or other liquid organic substances.

The subfamily Coelopsinae contains several genera, with Coelopa being one of the most recognized. Species within this subfamily can sometimes be found in large numbers, particularly in habitats rich in their larval food sources. Research on Coelopsinae primarily focuses on their taxonomy, distribution, and larval biology, contributing to the broader understanding of Diptera diversity and ecological functions.
