Periscelidids are small flies, occurring also in Europe and the Americas. They have been reported to be attracted to bleeding wounds of trees, and larvae have been reared from fermenting oak sap.

The genera Stenomicra and Cyamops have been variously placed in the families Drosophilidae, Asteiidae, Geomyzidae, Periscelididae, Anthomyzidae, and Aulacigastridae. Papp (1984) considered Stenomicra a distinct family, which also includes Cyamops because the 2 genera are closely related. Stenomicra is here placed in Periscelididae in the subfamily Stenomicrinae following Mathis (1993).

Stenomicra is pale and moves rapidly with equal facility in all directions while maintaining a constant orientation, which is often observed on the surface of leaves. Cyamops are dark flies with slow movements and a tendency to run about less than Stenomicra. They are found in wet locations such as vegetation beside streams and rivers. Cyamops may also be collected off of rocks in streams and rivers. Larvae of Stenomicra of the few species for which biology is known are aquatic or semiaquatic, living in water trapped in leaf axils. They occur in all regions of the world.
