distribution and habitat

The caterpillars live individually mainly from August, overwinter and pupate in May of the following year. They prefer to stay in a cave on the ground in the root neck area of clumps and feed on the roots and stalks of various sweet grasses (Poaceae), for example riding grasses (Calamagrostis), ball grasses (Dactylis), fescue (Festuca) or pipegrasses (Molinia).
