the mine contained several larvae
no oviposition scars could be found on the lateral veins; the interpratation of this scar is unclear
pupation in cocoons in the mine; the material has been bred, the identification was confirmed by Marc Delbol
Oviposition in the underside of a lateral vein. From here develops a large, full depth transparant light brown blotch that expands irrespective of the leaf venation. Mine mostly in the distal half of the leaf, may eventually occupy half of its surface. The mine often tears in, and the leaf tip is disfigured. The larva eventually pupates in a globular cocoon within the mine (Scherf, 1964a).
Salix is the main hostplant.
