Sorry the image is so poor. I was using the digital zoom because this wasp seemed especially upset and wary. You can sort of see in the picture how aggressive it's stance is. I thought we had Golden Digger wasps in the yard and there are holes in the ground just below where this wasp kept returning, but I've never had a wasp act this aggressively around me before. It chased me and bumped into both the dogs. It didn't sting any of us, but it seemed like it meant business. Plus I kind of thought it looked like a hornet, except it was SO big...
