A very rare and local species in Belgium.
The fore wings are light ochreous and the whitish lines are unclear. The antennae are all the way through white, or they are ochreous yellow and on the topside ringed alternating till the middle. Sometimes there are little black dots at the bottom. Wingspan is about 11–14 mm.
The egg is deposited on the inflorescence of Juncus articulatus.
The eggs are deposited on the flowers of the food plant. The larvae are feeding on the seeds. Larvae are to find in August and September. Once full fed, in September or October, they leave the host plant to hibernate in the surroundings.
They are on the wing from the end June till the beginning of August.
