A very local and rarely found species.
The forewings are lightly shining ochreous-yellow. The wingspan is 14–15 mm. The antennae are alternately ringed blackish white till the tip.
Caterpillars are making rather big mines some of them are used to enlarge their case. The case is bivalved and about 7–8 mm. The front end is very broad, the rear end strongly narrowed and strongly curved downwards. The mouth angle is 30°. They live mostly at the underside of a leaf.
