Hi, I’ve seen this Butterflie in Mexico….. What is?
This is one of the Swallowtail Butterflies in the subfamily Papilioninae. Many members from this group have tailed hind wings. Your image is not a species we recognize, but the markings are remarkably similar to a tailed species known as the Pipevine Swallowtial, Battus philenor. That butterfly ranges in Mexico and we do not want to rule out the possibility that your butterfly is a Pipevine Swallowtail that has lost its tails. The fragility of the wings often results in those appendages being easily damaged and lost.
