Ectoedemia hannoverella

The wingspan is 6–7 mm.[2] The moth is easily confused with Ectoedemia turbidella, both species having a white discal spot in the basal part of the forewing and many scattered white scales on a dark ground. The genitalia differ. They are on wing from April to May in western Europe.

The larvae feed on Italian poplar (Populus x canadensis) and black poplar (Populus nigra). They mine the leaves of their host plant, only feeding at night. The first instar larva bores in the petiole, causing a local swelling. Once the larva has reached the leaf disc it begins forming an elongate blotch between the leaf margin and the most lateral vein, or in some cases between the midrib and the first lateral vein. The frass is concentrated in two stripes running parallel to the sides of the mine.[3] Pupation takes place outside of the mine.[2][4]

It is found in most of Europe (except Ireland) to southern Siberia, but is most common in central Europe.[1] It was not recorded in Great Britain until 2002 when mines were found in the fallen leaves of Italian poplar.[2]
