First arrival in Belgium in 2009. Since then, it has spread mainly over the north and east of the country and it is now fairly common.
Pupation under a white, silken cocoon on the underside of a leaf.
Freely living instars live under consecutively three leaf margins or leaf lobes that are rolled downwards.
The species hibernates in the adult stage.
The adults fly in two generations a year: during June and from late August till May of the following year.
The larva feeds on Humulus lupulus and on the introduced Celtis australis.
