How beautiful!
I've never seen a falcate orangetip - I don't know if they don't occur here, or I just haven't happened to see one, I'll have to look it up.
Sounds like y'all had a good time!

Yep, we did. I'd never seen one before either, although they are apparently common here in the early spring. This is the first year I started butterflying so early.

The falcate orangetips were nectaring on a native arabis.

The undersides are marbled with gray streaking. They might be mistaken for cabbage whites in flight. Especially the females, who have no orange tips.
