It was known from two localities in LX. Now probably extinct, although stranglers of populations in northern France are sometimes seen.
The adults fly in June and July.
The larva lives on different species of Poaceae, like Brachypodium sylvaticum, Melica ciliata, Briza media and Cynosurus cristatus.
