Sphaeroceroidea
Sphaeroceroidea is a superfamily of small flies (Diptera) comprising approximately 2,600 species across several families, most notably Sphaeroceridae (small dung flies), Heleomyzidae, and Chyromyidae. These flies are generally a few millimetres in length and are associated with decaying organic matter. The superfamily is confirmed as monophyletic and represents the sister group to all other Schizophora. Taxonomic composition has been historically disputed, with proposals to merge families that remain controversial.
