The picture-winged flies are akin to the fruit flies. They are named for the striking patterns of their spotted or banded wings, which some species, when perched, wave in circles as if "rowing." The body shape of many species is antlike.
The common species Delphinia picta has a remarkably large snout that makes the face look like an old-style gas mask.
Similar species: There are several families of flies that are allied with this group, including fruit flies, lance flies, flutter flies, signal flies, and more.
