Zonantes subfasciatus.
Size: approx. 3 mm. Photo: 09/11/14, 10 pm.

This little guy has been tentatively identified as Zonantes subfasciatus which belongs to the family of the Ant-like Leaf Beetles. When I took the picture, all I saw was a tiny small speck. I believe the beetle was attracted to our porch light.
