No, this is atra:  Is yours perhaps a Phania? How large is it? Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

Oops, ok. I have no books or anything to compare with me. The fly is very small, maybe 5mm long. Just a bit larger than Catharosia pygmaea |

Just check the dorsal bristles on the hind tibia ... P.thoracica (lots of apical spurs) is very very rare but P.funesta (2-3 apical bristles) is very common

I think only the ones at the distal end count but I have never seen thoracica to check

Vibrissae are short, so not funesta... P. curvicauda is relatively common in Finland, but it should have darker calypters. I see only two apical bristles on the hind tibiae? Anyways, not bristly enough for thoracica? Would need to take it through the key to be sure. Sorry. |

Definitely one for careful keying
