A very rare species in Belgium, hitherto known only from NA and only found on calcareous soils.
Native
Early instars make a small corridor, that widens abruptly into a small full-depth blotch. A lot of frass in the corridor, but none in the blotch. Later instars live free in the upwards rolled leaf margin. The adults come to light.
The adults fly from June till late August.
