Only known from a very old record from the centre of the country (BR).
The species is still found in the Grand Duchy of Luxembourg, less than 15 km from the Belgian border in the extreme south-east, a good place to look for this presumed extinct species.
Native
Two short generations a year: end of May to mid-June and again from mid-July to early August.
