Ooo lovely! One of my favourite butterflies! It was recently assigned the new name Agraulis incarnata (so named as you tend to find the larvae feeding on Passiflora incarnata)

ah, brilliant! Thanks so much! (I was just recently introduced to the concept of "Sturt units' and went down a Sturtevant rabbit hole - the parallels to cMs are interesting, he must have been a real character).

it's going on the list, cheers!

I would 100% read this book.
