Self-propelled flowers: swallowtail and skipper

Here are a couple more butterfly beauties spotted this season.

I love the showy Black Swallowtails.

This swallowtail took off to frolic above the flowers with a flutter buddy.

While trying to ID this specimen, I got bogged down in the differences among the Common Checkered Skipper, White Checkered Skipper and Tropical Checkered Skipper. I think this is a common, although it deserves a more uncommon name.
