Host plants:
The caterpillars are polyphagous and feed on various plants of the alpine meadows (e.g. Viola species, but also Dryas, Polygonum etc.).

Habitat:
Boloria pales inhabits alpine meadows from about 1500m above sea level. In Central Europe it is only found in the Alps, but besides some Erebia often the most common species.

Life cycle:
The young caterpillar overwinters. The adults fly from June to August, rarely in September. They are often observed flying fast and low over ground or feeding nectar on flowers.

Endangerment factors:
Not at risk (local only by tourism and overgrazing).

Remarks:
The total distribution is restricted to some mountains of Central and Southern Europe (Northern Spain, Pyrenees, Alps, central Apennines, Balkans, Romania etc.).
