I saw a few of these very dark large wasp-like fliers feeding from my common milkweed plants today. Coastal Massachusetts. Very quick flier. Hard to get close to. Thanks!!!

Great Black Wasp

Hi Rob,
This is a Great Black Wasp and this image is gorgeous.  Female Great Black Wasps hunt Katydids to provision an underground nest where the larval wasps are developing.  The Great Black Wasp, 
Sphex pensylvanicus, and the Great Golden Digger Wasp, Sphex ichneumoneus, are classified together in the same genus.   This submission and your previous two postings are all being archived on our Milkweed Meadow tag.
