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.
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.
adults fly in two generations: from May to June and again in
Namur, Nismes, 29 October 2006.
