Sphaeroceroidea

Sphaeroceroidea is a superfamily of flies. It includes the cosmopolitan families of Sphaeroceridae (small dung flies), Heleomyzidae, and Chyromyidae, as well as a few smaller groups. It has about 2,600 species.

== Description == Sphaeroceroids tend to be small flies a few millimetres in length. Each of the families has its own distinguishing traits. For example, Sphaeroceridae have black wings with an interrupted costa, and the first tarsomere of the hind leg is short and thick. Nannodastiidae are even smaller than usual for sphaeroceroids, with adults being 0.70-1.25 mm long, and their legs lack long setae.
