Wingspan 7-8 mm.
This moth is common and widely found throughout Britain. It has two generations
and may be found flying in May and August.
It forms a long mine between the veins of a hazel (Corylus) leaf and is strongly arched. A similar mine is formed by Parornix devoniella, but this tends to be smaller, squarer and less arched.
The leaf mines may be found in July and then September to October.
