For finding females there are two basic strategies: perching and patrolling. Some males will wait on a sunlit perch for females to pass by; others will patrol a larger territory.
Virgin females advertise themselves by flying around shrubbery. A perching or patrolling male soon engages the female by fluttering around her. The female leads the male up to a high point on the tree where the male flutters briefly around the female. He settles and positions himself facing away from the female, moves towards her and pairing occurs.
Females lay single, white eggs on a variety of grasses along the sunny edges of woods, rides and hedges. The caterpillars are bright green with faint, darker green and yellow stripes and, thus, they are very well camouflaged against the blades of grass. Here they feed inwards from the margins of the leaf to the midrib. The green pupa is formed near the base of the food plant or on nearby vegetation. From egg to butterfly it takes two and a half months.
