Discovered for the first time in Belgium in all provinces during August 2007. Nowadays a fairly common species throughout the country, but more observed in the northern part.

The cocoon is yellowish brown of pinkish brown.
The eggs of the mining generation are laid on the wings of the fruits. Eggs of the summer generation are laid on the base of the petiole.
The larvae of the latest generation overwinter in hibernacula and spin their cocoons in spring.
The adults fly in two or sometimes three generations a year from April and May, during July and during September and October.
