This French site has another called Tachina magnicornis which also looks like mine, the black pattern on the body being the same. Their Tachina fera doesn't have the wider pointed bits on the sides in the middle, I translated their explanation on Babel fish which goes:

"Another photograph of Tachina (fera) will make: differ from T.magnicornis by the abdominal dorsal black band not forming rhombuses! (photograph M.Chevriaux)-Tachina magnicornis, 12-15 mm"

Translated from:

"Autre photo de Tachina fera : diffère de T.magnicornis par la bande noire dorsale abdominale ne formant pas des losanges! (photo M.Chevriaux)-Tachina magnicornis, 12-15 mm (photo L.Weitten)

When I googled for T magnicornis it was only this French site (plus one) which came up with pics., but this fly was here last year and many come from mainland Europe, more so in the hot year we had last year.

This German site has a pic of T fera which looks like mine

But in general there are other T fera which have straighter sides to the black pattern! Some of these are probably wrong!

On this site the pattern on the back of T. fera swoops in a curved line down the back with no pointed bit in the middle, confirming what the French site has mentioned "not forming rhombuses"

On this basis I'm going for Tachina magnicornis, what say thou?
