The length of the forewings is 4–7 mm for males and 3.5–6 mm for females. The forewings are dark brown, mottled with greyish white along the costa and dorsal margin. There are several white markings. Adults have been recorded on wing from late May to early October.
The larvae feed on Dianthus scaber toletanus, Dianthus deltoides, Dianthus arenarius and Dianthus sylvestris. They feed in the stalk of the host plant, which becomes gall-like.
