    The females lay their eggs close to the ground, usually on dry stalks of grass. The larvae feed on various grasses (Festuca ovina, Poa species, Nardus stricta), including Gramineae species. The caterpillar hibernates in the first or second larval instar and pupates the following year between June and August. Adults fly from July to September with a peak in August.
