Biology

One of the first fritillaries to emerge, the flight period lasts for about six weeks and occurs between the end of April and late July. A single brood is usually produced; eggs are laid singly on dead bracken or leaf litter near the foodplant (4). The caterpillars emerge after about two weeks (3) and when they are still small (5) they hibernate amongst leaf litter and emerge the following spring to complete their development. They pupate in the leaf litter and adults emerge after a few weeks (4).
