Assmann’s Fritillary occurs on warm grasslands and heath that are often situated at the edges of woodland, or near groups of shrubs. Its foodplants are Ribwort Plantain (Plantago lanceolata), Yellow Rattle (Rhinanthus minor), and the Speedwell (Veronica austriaca). The female lays her eggs in batches on the underside of the leaves. The caterpillars feed communally in a silken nest, where they also hibernate. They then separate, later pupating low-down in the vegetation. This fritillary is single-brooded.
