The Dixidae (meniscus midges) are a family of aquatic nematoceran flies (Diptera).

The larvae live in unpolluted, standing fresh waters, just beneath the surface film, usually amongst marginal aquatic vegetation.

For terms see Morphology of Diptera Dixidae are small (body length not more than 5.0 mm) slender gnats with thin legs.

The subcosta is fused with the costa at the level of the base of Rs or slightly proximal to this.
