The Ruddy Daggerwing (Marpesia petreus) is a fairly common butterfly in South Florida. Just a few weeks ago I saw dozens upon dozens at Castellow Hammock Nature Center. Green Cay may not have them in those kind of numbers but they are certainly present, especially on the Chickee Island. A few weeks back I managed to find one resting on the boardwalk that allowed me to take a few photos.
The unique wing shape and bright orange color make it easy to identify. Of course if the hindwing tails are missing it could be confused with a Julia Heliconian. The Ruddy Daggerwing is the only daggerwing that occurs regularly in the United States. This group of brushfoot butterflies are known for their daggerlike extensions and their fast flight. The caterpillar stage hosts on ficas trees (fig trees) and the adults in Florida favor Milkweed. With their wings closed they look just like a dead leaf but once they open up you see those three black lines running across the orange. This butterfly flies year around in Florida so if you're visiting or live in the area, keep your open for them.
