Big yellow butterfly seen near Tucson! - Zerene cesonia
Tucson, Arizona, USA
March 12, 2017
Size: 3'4" wingspan
This big yellow butterfly was seen in Sugaro National Park East near Tucson, in Mid-March of this year. And when I say "big", I mean bigger than other sulfurs and yellows I've seen, it was almost as large as a Monarch or swallowtail.
My best guess is an orange-barred Sulphur. Thanks to anyone who's better at Arizona butterflies!
