Recently discovered for the first time in Belgium in all provinces during August 2007. Also recently observed in The Netherlands (2004).

The egg is laid on a wing of the fruits of Acer campestre. The monophagous larva makes an irregular gallery leading into the seeds. In the spring it feeds on buds. 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; onwards during April and May, during July and during September and October.
