It is shouting "Lydella" at me but I can't find any features that would confirm it ... maybe Theo could comment? ![]() Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

Yes, correct, you can see the erect apical scutellars in the second pic. The eyes are bare and the scutellum is black, so it can't be Phryxe. I'd say it is a female L. stabulans, but females Lydella are pretty difficult to separate from pic. Theo |

Yes, the erect apical scutellars were fairly clear ... couldn't see a single hair at the base or r4+5 ... but the bare eyes and 'chin-less' face with wide frons were all making me think Lydella ![]() Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

Thanks, Chris and Theo, Lydella sp is quite good enough for me! |

Just to add some context, Lydella stabulans is one of the commoner summer tachinids in the UK. Lydella grisescens would be a better find but they are hard to split from a photo ![]() Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London. |

If the colours in the picture are any good, this can't be grisescens, this one is much too bluish. Theo |
