Wildlife Spotting

This is a fly, possibly a midge. Other than that, I haven't a clue. I was attracted to it because of its spider-like walk around the leaf, and its refusal to be intimidated by my camera. It has one pair of wings (notice the halteres). I've included a posterior shot so that you can see what appears to be two cerci. Unfortunately, I could not get enough magnification to show the antennae which I understand to be crucial to identification.
