A genus with 8 species globally distributed across the palaearctic and neotropical regions. The genus is absent from Ireland and represented in Britain by one species.
The genus Monardis run close to Cladardis in the Blennocampini and have the following characteristics. In the forewing, stub vein 3A is vaguely upturned at the apex. The pedicel is longer than broad. There is a measurable malar gap, which is little more than a line in Cladardis. The mesoscutellum has large, clearly defined punctures. In the female, the sawsheath dorsal face bears stout, blunt spines apically.
Larvae feed on unopened leaf and flower buds of Rosa species.
