Natural History: This has been an elusive butterfly in recent years. Although it goes through population explosions, they do not seem to colonize in the hammocks of urban areas of the Keys. We have seen them consistently in the hammocks of North Key largo. Females go through reproductive diapause in the winter and will live for months waiting for host trees to flush with new growth so they can lay eggs. This species rarely visits flowers.  They are typically seen perching on the trunks and branches of trees. They take quick short flights and land again and can be very difficult to follow because as soon as they land, their drab underside hides them well in the trees where they land.
