'The Common Butterflies and Skippers of Ohio' from Div of Wildlife, Dept of Nat Resources in partnership w/ Ohio Lepidopterists published this super 50p. booklet some years ago, I got mine in 2006. It has great pics and descriptions of their selections; I think every selection they've included in their publication applies to the gardens and central plains of Illinois as well. It's my first source to check and verify what I've seen or pictured in the heartland.
Anyway, the pictured Lady in question therein is named American Painted Lady (Vanessa virginiensis). The entry notes 'it was once known as the American Beauty', entry closes well, further stating 'which it certainly is.'
