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.

Thanks

Richard

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. :)

You could have tried the FAQ: http://www.dipter...p?cat_id=2. ;)

Hi, i've made this larger image, i'm unsure if it shows any additional features for identification?

Thanks

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

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.

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