At a lighted sheet. Size approximate--see comments.

Appears to be a member of the Chlamisini - Warty Leaf Beetles. Thanks for help (comments)--perhaps a more specific identification will be forthcoming.

Aha! Checking in Balsbaugh, Leaf Beetles of Alabama (1) (also on-line, I see the following lines from the key for genus Chlamisus (here):
1. Legs, antennae, clypeus, and frons not completely orange–either partly or entirely black..... 2
Legs, antennae, clypeus, and frons completely orange..... C. foveolatus

That sounds like a good fit to this photo. So I think this is likely Chlamisus foveolatus. It is also on a checklist from the Great Smokies.
