Not expecting to find any butterflies after 6 pm, I was caught by surprise at the appearance of what looks like a Parides photinus. Butterflies not being my field of expertise, I would appreciate confirmation of my ID. It seems to have a "swallow-tail", which the images I found for this species do show. It was photographed feeding on my zinnia; it never stopped fluttering its wings, so the image is somewhat blurry at the edges. The day was sunny and it had just stopped raining.
