The wingspan is 10–12 mm. Adults are on wing from late July to October and again, after hibernating, until May.[2]

The larvae feed on Acer campestre. They mine the leaves of their host plant. The first part of the mine is a hardly visible upper-surface epidermal corridor. This later becomes a triangular blotch-mine. Older larvae leave the mine and live freely in a spun together leaf segment. The larvae makes three such cones, each increasing in size. These may or may not be made on the same leaf. Pupation takes place in a yellow cocoon.[3]

Taxonomy

Some authors consider it a synonym of Caloptilia onustella.
