About Stigmella aceris (Frey, 1857) Gerasimov, 1952
Stigmella aceris is a moth in the Nepticulidae family, found in Europe. It was first described by Heinrich Frey in 1857. This moth flies from May to June, and again in August depending on location, with a wingspan between 3.7 and 4.7 mm. Larvae feed by mining leaf tissue of their host plants, creating a narrow corridor that is usually completely filled along its entire width with frass (waste). Females lay eggs on four maple species: field maple (Acer campestre), Amur maple (A. ginnala), Norway maple (A. platanoides) and Tatarian maple (A. tataricum). There is ongoing debate over whether this species also mines sycamore (A. pseudoplatanus): the resource Plant Parasites of Europe states it is never found on sycamore, while the resource UKmoths states it does occur on this tree.
