A very rare and local species in Belgium, nowadays observed in the most southern part of Belgium.
They fly from mid June towards mid August in one generation a year. They come to light.
The oligophagous larva live on the flowers and the seed capsules of Odontites lutea, sometimes also on Euphrasia stricta, Hypericum perforatum and Rhinanthus minor.
