Woodland Skipper (butterfly)

Given how fuzzy haired the body of this butterfly was and the deeper orange-brown color, I started wondering it it may be a moth. So I did some research on the difference between the two. This are two sites with the easiest to understand descriptions and facts:

The bottom line, this is a butterfly because of the antennas with knobs at the ends and the posture.
