The ripe caterpillars pupate near the plant , typically in the land or upper compost layer . After the adults emerge from pupa , they will receive someplace sheltered to winter , and then they will emerge in spring to distribute eggs and topsy-turvyness . The adult feed on nectar from flora cross-pollinate by moth ( low - sugar nectar flowers ) .
