Genitalia
The male genitalia are distinct in the very large, almost circular apex of the valva , combined with rounded transtilla lobes with strong apical denticles.
Caterpillar
Head and prothoracic plate shiny black; thoracic legs black; thoracic segment 2 slightly paler than the rest; abdomen pale green or reddish green, anal plate concolorous with abdomen; pinacula tiny; abdomen becomes suffused pinkish brown shortly before pupation (Gregersen & Karsholt 2022).
Bionomics
Early instars live inside the terminal twigs, causing withering of the leaves, later they live in a rolled leaf, eating half of it before changing to another leaf. Pupation takes places amongst detritus on the ground.
The adults come to light.
Flight periods
The adults have been seen from late June towards late September, occasionally later till late October. Most observations during August.
