Hi, Peter. Can't believe it's been two years since I commented... I just found a Common Blue last week, and when I saw the gallery in Nature Photographers, just had to come and drool. You've captured them so well, and are still doing so. THIS is now my favorite. I'm getting better, but they're tough little things to shoot. (We were at Sequoia Nat'l Park last August during mating season. Still didn't get one as good as this.)
