Hello, For this Cylindromyia photographed in the south of France, I tried to eliminate the species that I could. - bicolor : top of the abdomen red - intermedia : 2nd antennal article yellow - interrputa and pusilla : lack apical scutellar bristle - rubida and rufipes : orange legs - rubifrons : yellow frontal band - brevicornis, pilipes, brassicaria, xylotina : no pv on hind tibia It's more difficult with auriceps. This species, according to the key of central Europe Tachinidae, generally has discal bristles, but in a lot of pictures here I can't see these bristles. According to the key again, this species does not have pd bristles on tibia 2, but I think I can see pd on a few pictures in the forum. In France, we have too : scapularis and hermonensis. Any information on scapularis and hermonensis, and an idea for this Cylindromyia ?  Jessica Joachim : France : Cuq : 81570 : 19/06/2021 Altitude : 298 m - Taille : 10 mm environ ?

Hi Jessica, No, your supposed pv is avtually an av. Making these assessments from pictures is extremely tricky. Hermonensis / scapularis are very different. This is brassicaria group, very likely brassicaria. Theo |

Thank you very much Zeegers. For hermonensis/scapularis, they are very different, visually, in color ? And here, is the setae on the left of t3 a pv ? Or another ?  Jessica Joachim : France : Cuq : 81570 : 19/06/2021 Altitude : 298 m - Taille : 10 mm environ ? Réf. : 297106 |

Ok, thank you ! So, it's the same for hermonensis ? I can't find anything about this species in the forum search. |

yes. So best advice is to start with the common species. Once you have seen a hunderd brassicaria, you will pick out the rare ones with ease. Until that time …. Theo Edited by Zeegers on 19-01-2022 08:03 |
