A recent arrival in the south of Belgium (2006). Since then, more and more observations became known from other provinces and the species seems to be fairly common now.

The egg is laid on the underside of Acer campestre and Acer platanoides, close to a rib. The larva makes a long sinuous gallery filled for most of its length with coiled green frass.(in older mines blackish) The gallery is filled with frass in arches. 

The adults fly in two generations: from May to June and again in August.
