A local and very rare species in Belgium, mainly observed in the higher parts of the country.
Very variable in colour, from light green to yellowish brown with darker dorsal and dorsolateral lines; head brown or black; prothoracic plate greenish; pinacula black.
The larva lives within spun shoots of the foodplant.
Pupation in the larval habitation or amongst detritus.
The species occasionally hibernates in the adult stage. Adults are rarely seen. They hide during the day and become active at night. They occasionally come to light.
One generation a year: from July till September. Some specimens have been observed in early spring, suggesting that at least part of the population hibernates as an adult.
