Photo taken on 2012-04-21 in Reading, UK.

A small Tachinid, only about 4mm long, with long antennae. It was in long grass near willow trees. I only managed one in-focus photo before it flew off.

I think, it is a spring species of Siphona sp., in your area maculata is the most common.

Yes, geniculata would be rare at this time of year - certainly looks like Siphona. Would need a specimen to be sure of anything more :)

Yes, male geniculata has shorter antennae and four post-DC in contrast to this specimen.

Pity we can't see the side of the abdomen. They are such a difficult genus that I tend to switch off as soon as I realise that it is a photo of a Siphona! :D

Thanks Erikas and Chris. Now I look at the pattern on its back, it does remind me of Siphona but I was put off by the large antennae. I was actually going to collect this fly but it took fright when my net sprang open.
