We took this photo on a camping trip in the river hills of southern Lancaster County, Pennsylvania In mid July this year. We were close to a tree line and it was walking on the ground. It was so strange. I never saw a bug like this before… I was wondering if you can identify it??
This is the caterpillar of a Tiger Swallowtail, and its orange osmetrium, a scent organ, is just beginning to emerge.
