An uncommon species in Belgium, occurring in scattered populations all over the country.
A pure white cocoon.
The caterpillars of the second generation hibernate. Pupation takes place in the mine, inside a pure white cocoon. The adults are attracted to light.
The adults fly in two generations a year: from late April till late May and again in August.
