I'm pretty sure this is a tachninid but am unsure what species it could be. Photographed on the 20th May last year at Hod Hill, habitat was chalk downland, but it was found in a ditch amongst a colony of marsh fritillarys. Approx. 10mm.

Looks like a Phryxe sp. but the photos is a bit small to tell. Needs a lot more magnification really  |

Thanks Chris, i can try and enlarge the image, i was just a bit unsure what the site could deal with. I'll upload a bigger one tomorrow. Which features would be useful for identification? |

I usually stick to 500x500px or 640x480px and under 200KB in size. I'd always prefer to see a good dorsal shot (liek you have but bigger) and a good lateral shot. Tachinid keys rely on being able to see: the position of bristles on the thorax & abdomen; wing venation; leg bristles; hairs on the eye & arista; and bristles & hairs on the head/face. |

I'm afraid we really can't tell from this picture. It's not Phryxe, however. (eyes too close) Theo |

Yeah, it rings a bell ... but there's still not enough detail on the photo  |

It could be Carcelia, Phebellia, Nilea, .... so I'm not gonna guess. It is rather stout, though. Theo |

Hmm, well observed Theo ... Carcelia was probably what I was reminded of. |
