Macquartia sp. Interestingly late, here in north these are predominantly spring species. Jaakko |

Thank you Jaakko, With red femurs and black tibias, is it possible to restrict to a group of species ? Or these criterias are variable, too ? Very few species are illustrated in the gallery. Best regards Éric |

Very interesting ! The reddish femora strongly suggest M. viridana female, which is..... an very early spring species. Could you check the original to see whether the parafacialia is hairy or bare ? In this case, the very warm weather must have confused this girl. It is rare, but I have seen it before (Siphona maculata from october) Theo |

Thank you Theo Here are, in original format, the best three pictures I have showing the face. The parafacialia seems bare, but I'm not sure. Best regards Éric Eric Steckx attached the following image:  [67.47Kb] |

Lower images show that the parafacial is hairy! So Theo is right (again). Strange finding... |

See my other recent post. It really is either dispar or viridana, but things might be more complicated then simply viridana. The length of the prealar bristle is critical in females. It seems to be long (implying viridana, indeed), but it is very difficult to really see. The one by Christine is definitily dispar. So this made my doubt on this one. Theo |
