The “Comma” butterfly (Polygonia c-album) belongs to the “Angelwing” family, so called for their frilly airfoils. A splotchy, backwards “C” splattered across the dull underside of its wings resembles bird droppings, which helps camouflage the butterfly from predators and gives it the name “Comma.” (Sorry, I don’t have a pic of this — these little suckers are fast and super fluttery!)
