Pselnophorus heterodactyla

Description

Pselnophorus heterodactyla is a moth of the family Pterophoridae that is known from most of Europe. The wingspan is 18–22 millimetres (0.71–0.87 in). Adults are on wing in June and July in western Europe. The larvae feed on Mycelis muralis, Prenanthes purpurea and Lapsana communis. The larvae live on the underside of the leaves. They overwinter in the larval stage. In spring they bite through the midrib of the leaf, causing it to wither. Pupation takes place along the stem.
