The adult flight period occurs between July and August on heathland and between June and mid-July on calcareous grasslands. There is a single brood a year; eggs are laid singly near the ground where they overwinter. The following spring the larvae hatch, soon after hatching they are closely tended by ants of the genus Lasius which are attracted by sugar-rich secretions produced by the caterpillar, and provide protection against predators. Pupation usually occurs in or near to ant nests, and the pupa continues to be protected by ants (5).
