A rather common species throughout Belgium.
An inconspicuous linear mine on the underside of a leaf. See also bladmineerders.be
The first instars mine on the underside of a leaf, but later on they feed from a spun web also on the underside, usually folding the leaf downwards. Pupation amongst detritus or in the earth close to the foodplant.
The species hibernates in the adult stage. The moths hide during the day. They become active at night and occasionally come to light. They are also attracted to sugar.
One generation a year: from August, hibernating till early June of the next year.
Very different kinds of habitat.
