Not sure what to make of this calyptrate fly. Any help with narrowing down the ID would be much appreciated. Seen on 09/06/2021 in the margin of a commercial strawberry field in Kent, UK.

Many thanks,
Dylan

Looks like a female Musca autumnalis:

Wow, I never would have guessed that! I knew the females looked different to the males, but I didn't realise just how different they are. There's no way I would have guessed they belong to the same species.

Many thanks,
Dylan

Hello,

are you sure? Does not look much like a female Musca autumnalis to me, more like a Tachinid. Look at the sharper kink in the M vein.

Thanks for your help so far! Having had a look through the Tachinidae gallery, I'm now wondering whether it might be Cyzenis albicans? I appreciate that it may not be possible to tell for sure though from this photo.

Many thanks,
Dylan
