Sighting a Tiger Swallowtail on March 22!

A Tiger Swallowtail on March 22! I was so surprised to see one flying today! Usually they appear in mid-April. The temps were close to 60 degrees today, with sunshine and some wind, but this one was flying close to 15 feet above the ground. There is a mature willow tree near where I saw it, so it could be an early emerger. Spring may finally be here in Central Virginia!
