A rare and local species throughout Belgium.
Native
Eggs are laid singly but sometimes found in twos and threes, on the bark of Prunus twigs, nearly always at the base of a spine or the junction of one- and two-year-old twigs. Hibernates as an egg. Pupates in a crevice, on a dead leaf, or at the base of grass.
The adults fly in one generation a year from late July till mid-September.
The larva lives mainly on Prunus spinosa.
