This very rare species is not seen in Belgium for quite some time, probably extinct.
The wingspan is about 9 mm. This species has a white marking towards the base of the forewing, beyond the median fascia, making it quite easy to identify among similarly marked Elachistidae.
The larvae feed on the food plant, creating a mine typical of the genus.
Adults can be found between May and July.
