Food Plant: Populus alba (White Poplar), P.nigra (Black Poplar), P.tremula (Aspen), Salix repens (Creeping Willow)

Mine: early & late Summer

Notes: Forms a large greenish blotch mine which turns brown. The yellow larvae leave the mine to pupate and form a yellow to reddish-brown puparium, which glues itself to the substrate (as shown in dorsal, lateral and ventral view (top to bottom photo)). The larvae feed communally and were examined to distinguish them from Zeugophora spp. and Leucoptera sinuella.
