A very rare and local species in Belgium, with most observations in the southern part of the country.
Native
The larvae feed on the food plant, initally mining the leaves in a gallery in the autumn, starting at the base of the leaf, the mine is first filled with thick black frass which is later extruded through a small hole in the middle of the mine. After overwintering the larva feeds between spun leaves and/or terminal shoots. Pupation takes place on the ground.
The adults become active from before sunset and later can be attracted to light.
The adults have been seen from early July towards late August in one generation a year.
The larva lives on Stellaria holostea.
It inhabits open mixed forests and hedgerows.
