The moths fly in June and July, then aestivate in cool places such as tunnels and outbuildings, reappearing in the autumn.
In the late 1970s - early 1980s, distribution expanded greatly and the moth was recorded from over 400 10km sites, including Norfolk. It has since declined.
Scattered old Norfolk records, very few confirmed recent records.
