The wingspan is 9–11 mm. Adults are on wing from June to July.[3]

The larvae feed on Lysimachia maritima. They mine the leaves of their host plant. In autumn, the larvae mine out a number of upper leaves, migrating through the stem from one leaf to another. After overwintering, the larvae bore the stem of their host plant.[4] The larvae have a crimson reddish body and an ochreous-yellow head.
