Hi, I found out these pupae this winter in a wood and i rise them.  Villeneuve d'ascq (59), 15/03/2012, 8-10mm This is what came out:  Clovis : France : villeneneuve d'ascq : 59 : 30/3/2012 Altitude : NR - Taille : 10 mm environ Réf. : 83807  clovis : France : villeneneuve d'ascq : 59 : 30/3/2012 Altitude : NR - Taille : 10 mm environ Réf. : 83808 Is this the "Phaonia bristle" i see here or do i need to look elsewhere?  |

Hi Clovis. As nobdy has picked this up, I'll have a go. I think you may be right with Phaonia, but the 'phaonia bristle' is a posterodorsal in the distal (lower) third of the third (hind) tibia. It should be visible in your second image, though it's not clear to me. |

Hi, Thanks for your answer Stephen. Here is a picture of the third tibia Is it the one?  Here, you can see (hardly, sorry for the picture quality  ) the all 4 bristle there is on the third tibia. |

The only one that comes to my mind is Phaonia palpata (from general habitus), but the thoracic chaetotaxy is not enough visible to tell if I'm right or no.
Stephane. |

Eyes are hairy, and i can see on microscope 2 "almost" ac (big hairs) For the prealar i don't know, i'm having difficulty to locate it. I hope this picture will help:  |

To find the prealar, imagine a line between the first intra-alar and the posterior notopleural. You will find the prealar very close to this line, in front of the strong supra-alar. The pra is green spotted on the attached illustration. It is well longer than p. ntpl as you can see. The elongated prst. acr. hairs (almost acr.) are typical for P. palpata. I'm know more confident on the ID. Stephane Lebrun attached the following image:  [132.69Kb] Edited by Stephane Lebrun on 09-05-2012 19:21 Stephane. |
