Insect identification

I live in western North Carolina. I saw a small (~1 cm long) black insect today and have no idea what it was. Its most distinctive feature was that it had a flat, somewhat leaf-shaped abdomen which it held straight up- perpendicular to its slender thorax. It also had thick flanges on its back legs. It hid before I could take a picture of it.

It was probably a leaf-footed bug of the Coreidae family. This is an extremely large and varried family, so photographic comparison is typically the only way to compare species.
