Defense Mechanism


While beautiful and fragile-looking, the Gulf Fritillary (Agraulis vanillae) is not to be trifled with. This species is unique in that it has glands on its abdomen that release a noxious odor when threatened, prompting birds to move on to other, less smelly prey. While the view from above is striking, I find the silvery spots on the underside equally alluring.
