Voucher

It was sent to him in Poland (packed in a tube with cotton wool) and identified from that.

Although I am pretty sure someone else I showed the photo to at the time felt it could be identified from the picture.

Voucher

I'd be wary of getting an ID from any photo of a Phryxe species, they are not that easy even with a specimen sometimes.

No need to send stuff to Poland for ID, if you have a look at the Tachinid Recording Scheme website it does say we are more than happy to look at any UK material. :-)

Scheme

At the time (2007) the only name anyone had (on the various mailing lists I was on) for doing parasitic flies was the guy in Poland. Parasitic hymenoptera went up to Mark Shaw in Scotland.

Good to know about your scheme now though.
