Polystictus Swallowtail

A beautiful capture Sergio :)

Thank you again, bayucca. There were at least a dozen of these butterflies flying around those flowers, and some had a white back. I even thought they were another species for some time, but other than that they were identical to the other ones. Unfortunately I couldn't get a photo of the white back butterflies, they just didn't stop, and seemed to be a bit agressive against the all black backed ones.

Must be Battus polystictus. However, I cannot tell you about the white back that you might see in some specimens and in some not. But all other marking perfectly fit. Please, check yourself.

Gorgeous butterfly, Sergio, and the first photo is a very elegant image. Great series.
