Hi, Here is a specimen I'm not sure about the family. To me, this big subscutellum should make it a Tachinidae, but I can't make it fit in any genus (and with those longs hairs on arista, I believe it should be easy!) So maybe I am wrong and it is a Sarcophagidae? This specimen has two post ia Prosternum hairy 3 post dc, R1 hairy from radio cubital node, hairy till halfway to rm. Eyes bare (Lateral view of the head gives a strange impression of hairs on the face. It is same individu) Caught in the dunes.  clovis : France : Groffliers : 62600 : 09/05/2022 Altitude : 9 m - Taille : 6 mm Réf. : 315684  clovis : France : Groffliers : 62600 : 09/05/2022 Altitude : 9 m - Taille : 6 mm Réf. : 315685  clovis : France : Groffliers : 62600 : 09/05/2022 Altitude : 9 m - Taille : 6 mm Réf. : 315683  clovis : France : Groffliers : 62600 : 09/05/2022 Altitude : 9 m - Taille : 6 mm Réf. : 315682  clovis : France : Groffliers : 62600 : 09/05/2022 Altitude : 10 m - Taille : 6 mm Réf. : 315691 Edited by clovis on 01-12-2022 12:36 |

Very few Tachinds have paraficial bristles, a clear key pointing towards Sarcs. The ‘big postscutellum’ you mentioned is not the postscutellum, but the structure below it. The postscutellum is actually narrow. Theo |

Aaaah, I now have the explanation! Sarcophagidae was my intuition, but couldn't find how to objectify it! I didn't know that some structure could imitate the postscutellum, I'll have to be carefull. A family I know almost nothing about, I'll keep this specimen for a day I'll get to it. For now, I have to finish all my Tachinidae of the year! Thanks for the help

Take a Dinera, Tachina or other laege Tachinidae and study the postscutellum and the strucure below it. Then restudy this Sarc and you will reach enlightenment  Theo |

I did not expect Sheldon to be quoted on this forum^^ I had to catch a Sarcophagidae once to understand this subscutellum thing! Now i'm sure I won't miss any Calliphoridae hidden in my Tachinidae to Id! |
