Here today, gone tomorrow

I use Bing as the home page for my browser.
The background picture changes daily. Today's is of a fly (http://www.bing.com/) - download it if you want to keep a reference to it.
Any thoughts on identification?

Re: Here today, gone tomorrow

I have a problem here, Tony. Isn't Trichopoda an old name for Alloborborus? I have no idea what this fly is, but it surely isn't a Sphaerocerid! Or am I just missing a joke?

Indeed, Lioy used the name for a sphaerocerid, but that was in 1864. Back in 1827, Berthold had already coined the same name for a phasiine tachinid, so Lioy's use of the name was invalid, hence we use Alloborborus now. Trichopoda (the tachinid) is an interesting species that has spread around the world because of its use as a biological control agent against "stinkbug" pests such Nezara.

Thanks Tony. No joke then! I presume Trichopoda is not (yet) on the British list.

AFAIK Trichopoda is yet to be recorded from Britain, but it does seem to be spreading through Europe (from Spain and Italy), and has been recorded from France and the Netherlands, so I suspect it's just a matter of time. I'm not sure exactly which hosts it's using in Europe - this could be the restricting factor. Chris may be able to say more.
