Sphaeroceridae are flies in the Order Diptera, Section Schizophora, Superfamily Sphaeroceroidea , often called small dung flies.

Sphaeroceridae are a worldwide family of small, usually dull-colored flies.

The larvae are microbial grazers found in abundance wherever there is decomposing organic material. Most species appear to be associated with decaying plants or fungi. Some species, especially cave species , are polysaprophagous. Many species are associated with various kinds of faeces, hence the common name Lesser or Small Dung-flies. There are a few corpse-feeding species. These are extremely abundant and are important components of the carrion-insect community.They are also post mortem interval indicators in forensic entomology. Despite their ubiquity and abundance, little is known about the economic or ecological impact of sphaerocerids.

They have been implicated as the major means by which nematodes are disseminated among mushroom houses. They occasionally reach nuisance levels in food-processing plants and other buildings.

As their microbe-associated habits suggest, sphaerocerids carry many pathogenic microorganisms but their reclusive habits preclude a major role in disease transmission but some for this reason present a public health hazard.

One species, Poecilosomella angulata, has been implicated in human intestinal myiasis (Micks & McKibbon 1956).

Sphaerocerids that abound in economically important decomposer communities such as compost and manure, and some decay cycles such as the wrack cycle (seaweed) are mediated by sphaerocerid-dominated insect communities.
