The Pearl-bordered Fritillary occurs at the edges of woods and in clearings, in meadows and on pastures near scrub. Its habitats are usually dry and moderately rich in nutrients. The butterflies are quite mobile, leaving the habitat in search of nectar, visiting vegetation that ranges from very dry to wet. Most species of violet (Viola spp.) can be used as a foodplant. The female lays her eggs singly, either on a foodplant or on a neighbouring plant. The caterpillars feed on the violet leaves, hibernating in a rolled-up, withered leaf, when half-grown. The species pupates on the foodplant, close to the ground. It has one to two broods per year.
