A small genus of five species distributed primarily in the palaearctic region. Two species are known from Britain and in Ireland only Ardis pallipes is present.

The Ardis genus is characterised in the Blennocampinae by the following features. The outer margin of the eye is bordered by a groove filled with deep pits. The female sawsheath is reduced apically to a spine-like protruberance. The tarsal claws have an inner tooth and a basal lobe. The stub vein A3 in the forewing is not divided.

The larvae are modified for boring the stems of Rosa species and have reduced legs and setae.
