My butterfly book says the sexes of the Black ST are "dissimilar; female has reduced yellow postmedian band and increased blue hindwing scaling above". So I would say that's probably what you saw. They don't quite look like the other STs.

I don't know about that blue mark on your crescent, but it reminded me of a photo I took last week at MOSI. This Gulf Frit has a "spot" in about the same place, although his is more gray than blue. It makes me wonder what that is.

Sounds like you had fun! Thanks for all the pictures. I think sometimes the smaller, non-swallowtail butterflies don't get enough attention so I'm glad to see quite a few of them represented here.
