I was sitting in my garden a few summers ago, when this pretty fly landed on a banana peel. It stayed around long enough for me to take some photos and then vanished. I did not see any more like this around the garden again. I am pretty sure it is a Marsh Fly, a Sciomyzidae, but because I saw it away from a wetland I was not entirely sure. However, no other ID seems to fit, so unless I find out differently along the way, I'll call it a Marsh Fly. It certainly has the colour, size, shape, wing patterns, etc. of the Tetanocera genus.
