Meredith, even butterfly yelling doesn't seem to work!
You think this heat would be enough to move them north. Besides, I've never seen a Snout and you've got Red-Spotted Purples so I'd say you're doing well enough as it is! The butterflies are always better on the other side of the state line, I suppose. Your "babies" look quite grown up and I'm sure they remind you of that fact quite often! Hope you had a great Mother's Day!
