What kind are they?

Best guess, red admirals. Here's the cat, on nettle.

And a blurry side view.

The side view shows the white dashes on the caterpillar, making it a red admiral, and the chrysalis looks like a red admiral, also - question mark chrysalides are plain tan with a bright gold spot.

Congratulations!

Thank you! My first red admirals. It's been a good year for them. I've been seeing them almost every day. Last year, not a one.
