The Scarce Fritillary occurs in clearings, where young ash trees are growing in open, mixed wood- land. The eggs are laid in one batch on a leaf of Ash (Fraxinus excelsior) or Aspen (Populus tremula), preferably at a height of around 4 m. The caterpillars build a nest of silk and leaves, and feed to- gether at first, while still quite small. They go into hibernation, remaining in the nest, which usually falls onto the woodland floor. In spring, they leave the nest and separate, spreading out in search of food. They use a variety of larval foodplants at this stage, including honeysuckle (Lonicera spp.), plantains (Plantago spp.), or privets (Ligustrum spp.). They pupate in the litter layer. The species has one generation a year although some of the caterpillars hibernate a second time before pupating.
