Hi Valentin, based on your question I picked out now some specimen of Heringia and Pipizella and compared it with your pictures in "Le monde des insectes". As discussed the female belongs based on the flat and hairy face to the tribe Pipizini. I thought that it is belonging to Neocnemodon because of general appearance and the yellow basitarsi of p2. Neocnemodon is now seen as a subgenus of Heringia. The more carefull comparison has shown that I was wrong with my first opinion. I'm very sorry for this! Because of the long, bright hairs and the fact, that vein M1 meets R2+3 in a more or less right angle (not easy to detect on the pictures) it is belonging to Pipizella. The comparison has shown that your specimen is very similar to females of P. divicoi and P. zeneggenensis I collected in copula. Both species occure in your region. Nevertheless your female of Pipizella keeps undeterminabel on species level. Perhaps you collect some males of it. The good place for Pipizella in Gresy-sur-Isere seems to be the gras patches in the area north of Chemin du Touvet and west of Chemin du Moulin. Bonne chance |

I dont really know the Haute-Savoie but it seems to be one of the best known departements which the richest syrphid fauna reported from France. I only used Google Earth to figure out a place where I whould expect Pipizella at your place. I the past I had the chance to collect Diptera in regions like Provence, Massif Central, Vogeses, Cevennes, Pyrenees or Corsica. A new trip will start at the end of next week to Departement 66 for two weeks and I hope to get a lot of Pipizella. One day I will visite the Haute-Savoie. I used p2 for the midlegs. |
