Discovered in LG in 2021.
Native
Wingspan 7–9 mm. Male: antenna strongly serrate. On the ground colour of the forewing, mottled with a mixture of brown and white scales, minute and irregular areas of an ochre colour stand out; towards the apex, there is a yellowish-white triangular strip. Female: similar to the male, but the antennae are less serrate.
The larva hibernates in a long, narrow, redbrown mine, but changes to a new leaf in spring. The new mine starts from the base of the blade.
Probably univoltine, adults are on the wing from mid-May towards July.
The larva feeds on Carex sp.
Moist areas.
