Used to be known from two southern provinces, currently only present in a few localities in LG. Critically endangered!
The adults fly from early July till early August. They occur only in uneven years.
The larva lives on different species of Poaceae, like Calamagrostis arundinacea, Deschampsia cespitosa, and Molinia caerulea. The species hibernates in the egg stage, and a second time as L4 larva.
