Appearance

The small pearl-bordered fritillary (Boloria selene) is a small butterfly with a wingspan of 30–42 mm. The upper side is orange with black markings typical of fritillaries.

The underside of the hindwings is the key mark: a mosaic of white, rusty, and silvery spots. Seven silvery-white marginal spots and a large central silvery spot give a neat, "jeweled" look.

Range and habitat

Widespread in Europe, Asia, and North America. In Russia in forest and forest-steppe zones.

It lives on wet and damp meadows, clearcuts, and peat bogs. Linked to sites where violets grow.

Life cycle

In Russia one or two generations. Flight May–August.

Eggs laid singly on violets. Caterpillar overwinters. Pupa suspended, brownish.

Habitat conservation

The species suffers from drainage of bogs and wet meadows. Its numbers indicate the state of small river floodplains and wet clearcuts. It persists in mosaic landscapes where wet meadows alternate with scrub.
