I can't be sure from your pictures, but I think they're both males, a bit faded with age. Males have white spots on the undersides of their forewings, so in pictures where you can't see the forewings clearly, you can't be sure if the white spots on the topside are really prominent or they're just the underside white spots showing through.
Females fade to almost totally black on their topsides soon after they emerge - it looks like yours have some blue on their topsides.
Congrats on seeing them, though! Aren't they the hardest butterflies to photograph, moving their wings as fast as hummingbirds, it seems?
Here's a picture I got the other day - it's the only pose that'll keep PVSs still!

MissSherry, you're a national treasure. Thank you so much for telling me what to look for.

I checked back through all the shots and both butterflies have distinct white spots on their topsides. The pics that show the topsides also have a lot of forewing flutter -- magnificent to watch, frustrating to try to photograph.

They both had more color on the topsides than these pictures show. These pictures look a little green to me. I'll check my camera settings and maybe I'll get another chance tomorrow.
