It looks like a Tumbling Flower Beetle in the family Mordellidae.
They are quite small and I doubt do any damage worth worrying about, I've only rarely seen one at a time.
This looks like Tomoxia but I can't be sure, and it looks like a male (lacking pointed ovipositor).

Tomoxia lineella doesn't appear to be in Georgia, this pdf might give you clues.
Mordellidae, the tumbling flower beetles, are small, mostly black, wedge-shaped beetles
commonly found feeding on umbelliferous flowers, often in great numbers. The larvae are carnivorous
or are found boring in rotten wood, and some are leaf and stem miners. One Australian
species is parasitic on a scoliid wasp.
The family contains 201 species and subspecies in North America.
