I confess, I did not even see the small wasp when I was shooting the fly. The fly is probably 1/2 inch long. I guess that makes the wasp something like 1.5 mm!
This image is "posture stacked". I had two frames, very similar except that in one the wasp was in a good position but the front of the fly was incomprehensible, while in the other, the front of the fly was in a good position but the ends of its wings were cut off by the frame. This is a manual montage combining the best features of both frames.

Had to look for a minute before I realized where the wasp was at. Sure is a tiny little thing. Great shot there Rik
