Hello! I found this Pollenia today ( Febr. 14) , in Austria. The heigh was 1,73 km. I see the following things: - basicosta is yellow - abdomen is mostly dusted - the middle dark stripe in the thorax, doesn’t reach into the first part of the thorax (before the suture), so it is definitely not vagabunda I tried to figure out, which species could it be, and with a little doubt, it ended up in rudis. There are two species, what aren’t in my key: hungarica and angustigena. If I excluded them, it would be almost sure, that it is a rudis. There were a lot of flies, bigger and smaller ones as well, so this is a reason as well to rudis, because I’ve read that this species is so variable. Please, can you help me with this species? Is this really rudis? Or did I miss something, and basicosta isn’t yellowish? varganimrod attached the following image:  [69.5Kb] |

I can't tell if the basicosta is yellow, but it could be "yellow to brown, rarely black". To decide on rudis and angustigena, ad bristles of tibia 2 would help: usually! rudis 2-3, angustigena 1

Hello! I have a picture about the middle tibia: about this, do you think rudis or angustigena? I think, I see more than one ad bristles. Greetings, Nimród varganimrod attached the following image:  [38.39Kb] |

I think the upper one should be more distinct and so there's only 1 ad bristle on t2. It also seems, that in your image 5 femora 2 and 3 have the yellow posteroventral hairs. So - as sure as we can be in identifying Pollenia from photos: male Pollenia angustigena!

Thank you very much! So, is this the anterodorsal bristle? I still find it a bit hard, to name the bristles on legs.

Yes, that's the ad bristle. And here's a good explanation of the leg setae in the diptera.info glossary: https://diptera.i...&id=19 Greetings, Eric Kloeckner |
