Phyllonorycter aemula Triberti, Deschka & Huemer 1997

Two generations; adults in April – early-June, and July – early-August.
distribution within Europe
Northern Italy, Austria.
Cremaster with two pairs of spines; the inner pair rather slender, with their apices directed inwards; the pair, large and long, pointing outwards. Seen from above the outer pair widely exceeds the outline of the cremaster. Contrary to Phyllonorycter coryli and Ph. esperella the surface of the cremaster is smooth.
