In the northern part of its range, the Weaver’s Fritillary can be found on warm slopes with open woodland, scrub, and flower-rich grassland. More to the south, it is also found in damp, shady places. It can be very common in a traditional South-European agricultural landscape. The eggs are laid singly on various violets (Viola spp.). The caterpillars hibernate when half-grown in the litter layer. They pupate deep down in the vegetation. Weaver’s Fritillary has two to three broods a year.
