The ground. He was on my patio. I later saw him the grass. I picked him up and I am currently taking care of him so I may relocate him to Radnor Lake State Park tomorrow, which is only 10 minutes or so from where I live.
Male Flash Behavior:
Erratic flashing. Matches the description of a loopy five. Here are videos:

Not entirely sure if he was male, or female.

Thank you for submitting this observation of a Photuris firefly! Unfortunately, the flashes given by captured fireflies (for example one in a jar) will not be the courtship flash pattern that is helpful for ID.
While many Photuris look very similar, the non-wetland habitat make it unlikely that what you observed was a loopy five firefly (Photuris forresti).
