That is so beautiful. I haven't seen that many butterflies this year for some reason. Thanks for sharing... Vicki
Gorgeous! It's funny you should post this, because for the first time since last year, this weekend, those pretty, large dark blue butterflies showed up in my lantanta again! I thought maybe my overzealous-ness in the Japanese Beetle war might have killed them off too, but I was so happy to see them again! I love lantana. I am SO happy to live in a climate where it's beautiful and it comes back, but it doesn't seem to take over and become a nuisance!
Papilio Alexanor, subspecieis 'Glaucus', aka "Southern Swallowtail", aka "Eastern Tiger Swallowtail" (I've heard both used)
I'm not a scientist, so can't tell you more. Used to collect butterflies as a kid, and it's clearly a swallowtail.
