My observations: I noticed a butterfly or moth land in front of me in my backyard on a sunny day, temperature about 85. I noticed the underside of the wings which appeared to look like leaves, perfect camouflage for the pine trees around here. The specimen seemed to be sun bathing as it flared its wings down to show its beautiful coloration. The uneven black spots on orange background faded to red around the rims. Absolutely stunning coloration, I really wish I had gotten a picture but the one time I don't have my phone on me..
