A very rare and local species. Status is uncertain because it's rarely attracted to light and therefore not often seen, but it's easily attracted with pheromone.
The species hibernates in a whitish cocoon inside the gall. The adults come rarely to light but are easily attracted with the pheromone of Cydia fagiglandana.
The adults have been observed from mid May to early July.
