A Soldier fly, or something confusingly similar?

When I first saw this, I thought it was a Jewel Wasp, but then decided it had to be a fly. With the brassy colours, I thought a Soldier Fly was a good bet, and the venation looks compatible. But there isn't a Soldier Fly that looks like this. So either it's an abnormal presentation of one, or maybe it really is a wasp.  The last image show the abdomen to be a mix of blue and purple.

It was far too mobile to get a good picture, so only one image is not blurred. Size-wise, a leafhopper nearby (Macrosteles sp at 3-4 mm) indicates it is about 7-8 mm. Above cattle dung. It got batted away by a much bigger fly, so that ended the chance of more images.

At that size, this is most likely to be Sargus flavipes.

Re: A Soldier fly, or something confusingly similar?

As ever, thanks for the pointer, Tony.
That was the most likely of the ones I had looked at, but rejected on the basis that it was meant to be green, and Stephen Falk's Flickr album for that one shows very dark soldier flies, which don't look a good match for mine at all.

However,  following on from your pointer, I have now looked further afield.  I thought the same would be true for the Dipterists Info site - the first few are green, but then a couple of images in that collection look very good matches with the brassy red, orange, and green hues.  Size-wise, I think it has to be that, because the leafhopper acts as a good measure for its small size.
