Pays To Take A Second Look

So I was poking around some goldenrods, as one does when one is looking for pollinating insects in August, and I happened to snap some photos of what seemed at first glance to be two individuals of the same species, or at least the same genus. 


Joke's on me; despite superficial similarities, the top one isn't even a wasp - it's a fly (Physocephala sp.), as evidenced by the shape of the antennae. The fly family is so much bigger and more varied than most of us would think, and so many of them look absolutely nothing like the typical house fly. The bottom one I believe is a Mexican Grass-carrying Wasp (Isodontia mexicana), which despite its name appears to be native to my area.
