rare and local species throughout Belgium.
larva lives mainly on Prunus spinosa. 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.
adults fly in one generation a year; from late July till mid September.
