Well, it didn't take long for those Gulf Frittilary butterflies to find their favorite host plant, your Passionflower! In just a few days you accomplished what most of us have to wait at least a few weeks or months for! The larval form of this species, Agraulis vanillae, depends on the Passionflower genus for its survival. All of us in the Southern U.S. should have at least one plant in our habitats, if for no other reason than to enjoy the Gulf Frittilary life cycle all summer. Yes, the caterpillars will eat quite a few leaves, but the vine bounces back quickly and will be ready for the next baby boom. Enjoy!
