I'd say so. It does not look ordinary (then again, there are many species in this genus) Theo |

it is Bellardia but species level is difficult with keys. I think that it is between vespillo and vulgaris. I have zero specimens for Bellardia so I have no idea how to interpret the work of Knut Rognes. Knut Rognes states that vulgaris has pale wing veins but offers no comparison of dark versus pale. The wing veins of this fly look dark and the wing is infuscated. stricta is mentioned as having infuscation but nothing else matches stricta. bayeri is supposed to have a dark spot on the parafacials that is visible from above. I see a dark line but nothing conclusive. The white dusting of the parafacials verifies a male and the dusting is weak because photo number 5 shows a completely dark face. I will assume that vespillo is the best match but I have nothing to compare it with. Maybe someone here has experience with Bellardia? otherwise, a good photo of the cerci/surstyli will be helpful. lateral and dorsal views. John and Nini. Naturalists not experts. |

Could be Bellardia viarum, which is indeed between vespillo and vulgaris, in the alphabetic sense  I'm not enough confident to give a definite ID without genitalia examination for this one. Stephane. |

Knut Rognes mentions that viarum is similar to vulgaris but darker. I think that this fly is not so dark but I have nothing to compare it to. I think that there are no long discal setae on T4 but you are much more knowledgeable, so you are probably correct. genitalia is easier for me. John and Nini. Naturalists not experts. |

In matter of Calliphoridae, I'm not so knowledgeable, I'm very new in this family, so your opinion is as important as mine.  Stephane. |

well I disagree that my opinion matters here. I have followed your posts for over a year now. You are an amazing dipterist. I do not belong in the same forum as you. I hold you and your opinion in high regard. As far as I am concerned, Stephane Lebrun is one of the best in the world. I am studying Calliphoridae but I have alot to learn. I am just now identifying Pollenia by genitalia. I have no experience with Bellardia. I try to be helpful here but I will always back down when an expert posts a reply. I yield to you now Sir Stephane. By the way, alot of my knowledge comes from you. I maintain a text file with notes from your posts I wish for you a Wonderful Day. John and Nini.
