My Most Viewed Butterfly?

This female Easter Tiger Swallowtail Butterfly remains one of my viewed wingedbeauty images, ever. Taken at Raccoon Creek State Park in southwestern Pennsylvania, some nine hours west of the Empire State Building in New York City.

One of my most viewed ever.

Do be so kind as to share with me. Why have so many of you taken the time to have a look at this particular butterfly?
