Ectoedemia turbidella

The wingspan is 6–7 mm. The wing ground colour is grey There are creamy white forewing patches and the head has an orange or yellowish tuft and whitish eyecaps. Adults are on wing from May to June.[2]

The egg is laid on the petiole, about one cm below the base of the leaf of silver poplar (Populus alba) or grey poplar (Populus × canescens); often one on each side. They mine the leaves, first feeding in the distal part of the petiole, resulting in a local swelling, approximately 10–15 mm long and twice the normal thickness. When the larva reaches the leaf it makes an elongate triangular blotch between the leaf margin and the first side vein, or sometimes between midrib and side vein. The frass is concentrated in two bands that run parallel to the sides of the mine. The larvae mainly feed at night. Pupation takes place outside the mine.[2][3][4]

It is found in most of Europe (except Ireland, Greece and the Mediterranean islands), east to the Volga and Ural regions of Russia.[1][3]
