I have run this through Belshaw twice and arrived at Brachicheta, which it clearly is not. Can anyone suggest what it may be, so I can try again? UK 12 June, from wet heathland with trees. Size: 8mm length. conopid attached the following image:  [175.94Kb] Nigel Jones, Shrewsbury, United Kingdom |

Might it be from Sarcophagidae? |

I don't think it's Rhinophoridae, but I am not at all familiar with them. Lydella may be a possibilty - it does look rather like that (but then many Tachinids are superficially the same!) I'll compare with Lydella in my collection. Thanks for the suggestion.

Lydella (not stabulans) is a good candidate. The genus is easy to recognize: one strong bristle in the r-vein node (can be seen in the pic) and 4st (three in some stabulans females, but these have characteristic pattern on the abdomen). How does the face look like in lateral shot? |

Lydella was my first impression as well, but there are strong discals on tergites and the tip of the scutellum seems to be pinkish. The praealar seems to be short My current guess would be Chaetogena Could we please get a lateral of the face ? Theo |

Black hairs behind the post-ocular row... Not i]Chetogena[/i]. Were there four katepisternal bristles? The bristles on the facial ridges rise quite far, but habitus is still Lydella to me. |

I agree Looks totally like a male Lydella. But which species ? if the abdomen really is so hairy, it should be stabulans. But the vertex is too broad, the claws are short and the head profile does not fit. Apparently, the first pictures are somewhat misleading. The It is very likely the male of L. grisescens |

Thanks Theo, I shall investigate along those lines. This may be one that I'll have to send to Chris for determination! Nigel Jones, Shrewsbury, United Kingdom |

Yes this is Lydella and is probably L. grisescens. It was the wing venation that did not match the couplet in Belshaw, so there is a very small chance that it might be L. thompsoni. I'll send it to Chris R just in case, but most likely it's grisescens.

Chris, Great,I have it in a box along with a few other specimens for validation/determination. Did you get the spreadsheet of Tachinid records I emailed a few days ago? Nigel Jones, Shrewsbury, United Kingdom |
