Tabanoidea

Superfamily Tabanoidea are insects in the order Diptera.

Oreoleptidae is a family of flies (insects in the order Diptera). The family was established in 2005 on the basis of the type species Oreoleptis torrenticola placed in the monotypic genus Oreoleptis. The only known species was collected from the Rocky Mountains where the larvae grow in torrential streams. Larvae have also been found in groundwater wells. The larvae are similar to those of Athericidae and Tabanidae but with long crocheted false-legs (prolegs) arising from abdominal segments 2-7. The larvae have hollow mandibular hooks.
