A rare species in Belgium. 

The larvae feed on Acer campestre and to a much lesser extent on Acer platanoides. Initially it makes a full depth blotch mine and later it forms successive cones by curling a portion of the leaf downwards. Pupation takes places nearby the cones on the underside of the leaf close to a vein.

The adults fly in two generations a year; during July and early August and again from September towards May. They  come sparsely to light.

Note: All Acer-feeding Caloptilia species are belonging to a group were evolution is still in progress. Some taxa are very similar genetically and difference in DNA structure is minimal. Due its variability and resemblance to different species like C. fribergensis and several others, it is necessary to examine the genitalia.
