Thanks, vienna... that's very interesting
Blue butterfly species (of which there are many) are especially fascinating, and your
El Segundo puts me in mind of our own Large Blue (now extinct) with its peculiar life cycle:

I believe that a Continental race has been released in secret locations in the UK in hopes to 'reintroduce' this beautiful insect... but to my mind it could never replace the real Large Blue. They've done the same with the magnificent Swallowtail Butterfly, but I would only travel to the Norfolk Broads if I could see a genuine native Swallowtail
