The wingspan is 15–19mm (0.59–0.75in). Adults have ochreous forewings. They are on wing from July to August.[2]
The larvae feed on white rock-rose (Helianthemum apenninum), common rock-rose (Helianthemum nummularium), Helianthemum nummularium obscurum and annual rock-rose (Tuberaria guttata). They create a large, composite leaf case of 10–15mm (0.39–0.59in) length. The fully developed case consists of three successive leaf fragments. It is light brown, bivalved and has a mouth angle of about 45°.[3] Larvae can be found from September to the end of May of the following year.
