The Common Brassy Ringlet encompasses 4 taxa which are included in this species complex: arvernensis, cassioides, macedonica, carmenta. They represent isolates in different glacial refugia. Their separate species status however is still uncertain and requires verification. The butterflies live on dry, grassy slopes, rocky slopes with patches of grassy vegetation, and scree. The females lay their eggs on dry stalks of grass, close to the ground. The species’ foodplants are various fescues (Festuca spp.). The caterpillars hibernate in the first or second larval instar and pupate the following year between June and August.
