Could it be a Great Black Wasp - Sphex pensylvanicus?

Although that is a possibility, please bear in mind that there are other wasps in that family (Sphecidae) that can have a very similar appearance - see http://tinyurl.com/2abcwoj for an example (likely a Prionyx sp.).

No - these wasps usually specialize in insects in the order Orthoptera, such as grasshoppers, crickets, or katydids.

The primary differentiation between the two families is in the structure of the pronotum; in the Sphecidae, there is a little knob-like lobe at each side of the pronotum just above the base of the fore coxae, this is lacking in the Pompilidae. As this may not easily be seen without use of a magnifier, a good (but not 100% reliable) field character is that spider wasps (Pompilidae) usually have longer legs, with the hind femur often extending beyond the end of the abdomen.
