At least I know he must be. This is the first time all summer I've caught him landing - this clouded sulphur likes the cardinal flowers in the creek and stayed put quite a while. His opposite is in my other album. http://365project.org/milaniet/2013-extras/2014-09-12
@sailingmusic Well, for a long time they were all tagged yellow butterfly or bug on my computer until I got the National Wildlife Field Guide to Insects and Spiders of North America. They haven't let me down too often.
You captured such detail in his face. He rather looks like a chameleon to me. (That might require some imagination to see. :) Beautiful picture, Milanie.
