Freddie, if you're concerned that some of your other pictures aren't very good, don't worry, I won't denigrate them. Even a blurry, badly lit (or worse) picture can often be helpful when it comes to identifying a critter or plant. And I know how hard it can be to get good pictures of some things, especially when they don't sit still.

Regarding the checkerspots, I'd say that the second picture is a chalcedon checkerspot (Euphydryas chalcedona) which is also also called 'variable' checkerspot, etc., etc., and some people consider the chalcedon to be the same as the colon checkerspot and maybe even the same as the anicia checkerspot. Yeah, it's a bunch of lumping or splitting and just plain confusion. The same thing goes for some lycaenids and many other butterflies. Taxonomists like to throw a lot of names at things before they know what they actually are.

Edith's checkerspots are easy to identify if you have a ventral view. They have a thin dark line running through one of the orange/red bands on the hind wings. The chaos with Edith's starts when it comes to "sub" species, "forms", etc.

The butterflies know what they are. :)

The white spots on the abdomen of the second checkerspot above are also an indicator that it's a chalcedon although the white spots aren't always there. I think that the first one is also a chalcedon ('variable', etc.) but I wish I had a ventral view to be sure.
