Ectoedemia turbidella

Description

Ectoedemia turbidella is a moth of the Nepticulidae family. It is found from most of Europe (except Ireland, Greece and the Mediterranean islands), east to the Volga and Ural regions of Russia. The wingspan is 6–7 mm. Adults are on wing from May to June. The larvae feed on Populus alba and Populus canescens. They mine the leaves of their host plant. It first bores in the distal part of the petiole, resulting in 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 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. - - -
