About Brenthis ino (von Rottemburg, 1775)
Brenthis ino, also known as the lesser marbled fritillary, is a medium-sized butterfly with a wingspan of 34–42 millimetres (1.3–1.7 in). Females of this species are larger and usually darker than males, and their antennae are clavate, or club-shaped. The basic upper wing surface is orange, marked with multiple dark brown blotches. The wing edges are also brown, with a discontinuous stripe of small blotches. The lower wing surface is creamy orange with an indented edge; forewings have dark brown blotches, while hindwings bear brown-edged beige blotches and some ringed dark brown and violet shaded spots. This species has no silver blotches on its wings. Depending on location, adult butterflies fly from June to August. It overwinters in the caterpillar life stage. The larvae feed on meadowsweet (Filipendula ulmaria), dropwort (Filipendula vulgaris), stone bramble (Rubus saxatilis), raspberry (Rubus idaeus), plants in the Aruncus genus, plants in the Spiraea genus, and salad burnet (Sanguisorba minor). The lesser marbled fritillary is found in Spain, France, Italy, central and northern Europe, Siberia, temperate Asia, northern China and Japan. It lives in damp meadows and bogs at elevations from 0 to 1,500 metres (0 to 4,921 ft) above sea level.
