Rhagionidae
Rhagionidae or snipe flies are a small family of flies.
They get their name from the similarity of their often prominent proboscis that looks like the beak of a snipe.

has been demonstrated in adult ''Suragina'' and ''Suraginella'' and is suspected in other genera. Larvae do not feed in the first instar; after first molting, they become predatory. Larvae typically prey on invertebrates or are saprophagous.
The larvae have distinctive morphology. Their head capsule is well developed dorsally, and they have long abdominal

. Adults have stout, tapered abdomens, slightly elongated legs, with aristate antennae. Males are sexually dimorphic with holoptic eyes.
Adult athericids usually rest on the upper surface of leaves, near the streams from which they emerge, or more inland if they are looking for a blood meal. Athericids commonly stroke or palpate the surface of leaves, an action they share with the Tabanidae. All species deposit their eggs at one time and then die.
