Last year in May, Terri and I were riding our bikes along A1A north of Jensen Beach and we were chased by 6 or 7 Great Southern White Butterflies for several hundred feet. It was amazing that they could actually keep up with us! The St. Lucie County Parks are the best areas with their natural vegetation to observe these fast fliers. The Great Whites are typically found along the coast and Keys of South Florida and can be identified by their color and the constant flapping of their wings. These butterflies can be seen all year.
The caterpillar’s food sources are the Saltwort, Peppergrass, Capers, Cleome, and Mustards.
