Ectoedemia turbidella (Zeller, 1848)
Populus canescens, Belgium, prov. Namur, Couvin, Mariembourg © Stéphane Claerebout
mine with larva, lighted from behind
The egg is placed on the petiole, about a cm below the base of the leaf; often one egg at either side. The larva first bores in the distal part of the petiole, that shows a local swelling. When the larva reaches the leaf it makes an elongate triangular blotch between the leaf margin and the first side vein, or, less frequently, between midrib and side vein. Frass in two bands, parallel to the sides of the mine, created by the passage of the larva when it retreates into the petiole. The larva mainly feeds at night. Pupation external.
Populus alba, canescens.
Only in the smaller leaves of older shoots of large trees, never on saplings (van Nieukerken, 1985a).
Larve in the petioles in August, in the leaf mines from mid-September; mines often in green islands, also in fallen leaves (Hering, 1957a).
BE recorded (Phegea, 2009).
NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2009).
