I can't even work out what family this fly is from. Found it holding territory in a shady nettle patch close to a small pond near the village where I live in Cheshire, UK. I thought it was a hoverfly from it's behaviour, but it has a distinctive bristle pattern on the dorsal surface of its thorax, so can't be one of the Syrphidae. Anyone any idea what it is and which family it belongs to? Thanks Ray Wilson Nottinghamshire UK http://www.raywil...aphy.co.uk |

Thanks Nikita. I was under the mistaken impression that the male Dolichopodids had large genitals curving under their abdomens. Obviously I was wrong and some don't. Is this a female of the same species or a less well marked male? It was photographed on the same patch of nettles at the same time as the first photo.
