Mating behaviorEdit

There are several flights (early spring to late fall) in the northern part of the range and nearly year round in peninsular Florida. Males patrol open areas near host plants for females. Mating occurs primarily during mid-day. Eggs are laid in clusters on the undersides of leaves of the fogfruit host plants. The common host throughout much of Florida is turkey tangle fogfruit (Phyla nodiflora).
