Junonia coenia
Female buckeyes lay eggs individually on buds and leaves of host plants. The larvae (caterpillars) emerge and feed and grow on the host plant, molting several times. Larvae transform into pupae, and spend the winter in this stage in the northern part of the range. Metamorphosis is completed in the pupal case, and fully developed adult butterflies emerge. They can take flight after their wings dry. In the southern half of the range, this species may develop and reproduce continually with no diapause or winter dormancy. Males perch on the ground or low plants and watch for passing females. They pursue any likely object. Females inclined to mate will land, and the male will follow. Courtship behavior is variable. Sometimes they land, fold their wings, and mate. On other occasions females have been observed fluttering their wings after landing. The male responds by hovering over her and fluttering his wings as he lands behind her. The male will then pursue her by nudging her from behind. They will then mate, or if she chooses not to mate, she will flap her wings with a high intensity, spread her wings and lift her abdomen to deny him access, or just fly away.
