another mine

Populus x canadensis, ter Heijde, 19.x.2018 © Jan Scheffers: unusual, lower-surface, mine (also visible the feeding trace of Gypsonoma dealbana)

mine

Egg either at upper- or lower-side of the leaf. The mine is an upper side corridor; the first part is rather straight and narrow, and often follows a vein for some length; the second part is much broader, sometimes almost a blotch. In the first part of the mine the frass lies in a more or less uninterrupted central line that does not occupy the full width of the gallery; in the second part the frass pattern is very variable, ranging from a narrow central line to a broad band.

synonyms

Nepticula trimaculella; Stigmella populicola (Sorhagen, 1922); Stigmella subtrimaculella Dufrane, 1949. Several authors consider St. subtrimaculella a valid species (eg Arru, 1966a; Zoerner, 1969a), that would be characterised by having a very fine frass line, while the one of trimaculella takes a good part of the width of the corridor.
