Today on Backyard Visitors, we have a Giant Swallowtail Butterfly, Papilio cresphontes. This one has seen better days and is probably near the end of its life. It was perched on my rubber boot on the back porch. After this picture, it flew away, proving it still has some life left.
The caterpillars look like bird poop. So, be careful the next time you go to clean poop off your car. You might be squishing a beautiful butterfly.
