Host plants:
The caterpillars feed on grasses (Festuca species and probably also other species of stony slopes).
Habitat:
Pseudochazara graeca inhabits sunny, stony to rocky or other places that are rich in open soil spots, mostly extensively grazed slopes between 800 and 2300m above sea level.
Life cycle:
The young caterpillar overwinters (about one third grown) and is at least in the spring pure nocturnal. The butterflies are on the wing from late June to mid-August (rarely later) and like to visit flowers (e.g. Dianthus species) or rest on stones and open ground.
Endangerment factors:
Pseudochazara graeca is locally endangered through overgrazing, ski resorts, succession, quarrying, road construction and similar measures.
Remarks:
Pseudochazara graeca occurs in the southern Balkans, especially in Greece in the Pindos range and on the Peloponnese, but is also found in southern Albania and Macedonia.
