There is something very rewarding about finding something one has been searching for his whole life long, but which in the past has always proved to be elusive. A Tiger Swallowtail caterpillar is one of those things for me. I've been hoping to find one since I was a kid, actively looking for one without any success.
But then, just last week, I noticed this guy hurrying across the road.
When he grows up, he'll look like this.
