Hello, I am new ont this forum and not very good at English so excuse me for mistakes. It is about this little fly (4mm), recently presented on LMDI which is probably Azelia for the genus but it is more dificult to give it a species. Could it be Azelia nebulosa though the diptera's specialist of LMDI does not see bristles on hind tibia, usual for the species, and finds strange two white points above the antennas. Thank you for answer, Dominique  Oryctes : France : Villeneuve-d'Ascq : 59650 : 11/08/2019 Altitude : NR - Taille : 4mm Réf. : 237816  Oryctes : France : Villeneuve-d'Ascq : 59650 : 11/08/2019 Altitude : NR - Taille : 4mm Réf. : 237817  Oryctes : France : Villeneuve-d'Ascq : 59650 : 11/08/2019 Altitude : NR - Taille : 4mm Réf. : 237818 Oryctes : France : Villeneuve-d'Ascq : 59650 : 11/08/2019 Altitude : NR - Taille : 4mm |

Hello, I am back to ask Nikita Vikhrev, if possible, another question about this little fly... In your kind and interesting answer, you wrote it was "probably A. monodactyla". It is not easy to find photos and descriptions of this species. Looking etymologically the words, I wondered what the term "monodactyla" could indicate. Could it be the single claw we can see on the fore tarse of the insect (detail of a photo already here) ?  Oryctes : France : Villeneuve-d'Ascq : 59650 : 11/08/2019 Altitude : NR - Taille : non mesurée Réf. : 238811 Thanking you in advance... Dominique |

Hi Dominique. For information you can use my revision of Azelia, it is available here: https://ia600308.us.archive.org/31/items/ReviewOfTheWorldFaunaOfTheGenusAzeliadipteraMuscidae/Amur15-1_Vikhrev.pdf Several other species of Azelia have fore outer claw modified as on your photo, for example, A. beuki which I named in honour of foundator of diptera.info Dr. Paul Beuk  But A. beuki is Oriental species connected with elephans which are absent in France. Your male has p seta on t1, this character it shares with A. parva and A. spinosa, but in both mentioned species fore outer claw is of normal size or almost so. Thus, your photos are A. monodactyla on my guaranteeю

 And add the first, too, because that one shows the abdominal pattern.

Thank you very much, Nikita Vikhrev, I am delighted by your complete answer and obviously I will read in full your work on genus Azelia. I confess that I did not know you had done a so important work on Azelia and it is with great pleasure I have discovered that. If possible, I will follow your advice and submit 3rd image to the Diptera Gallery... Dominique |

Really a good day ! Thank you Paul Beuk for your suggestion. I will be happy to do that but, as I said, it was my first time here and I do not know exactly how to send the photos on Diptera Gallery. I have to examine this matter ! Dominique |

Hi Paul and Nikita, I downloaded for the gallery the two photos of this subject, their author having failed to do so. Thanks for identification. Eugene |

Hello, Here is a photo of a possible Azelia monodactyla caught foraging on a flower. The photo shows "tar2-3 ventrally with waved hairs" which is similar to the figure in Nikita's 2015 Azelia article.  Pierre-Yves GLOAGUEN : France : Confort Meilars : 29790 : 30/08/2019 Altitude : NR - Taille : 3 mm Réf. : 239227 I can send a male sample to confirm identification if you want. P-Y

A. monodactyla without doubts. It is common on horse dung (though horse dung is uncommon presently). Also, on the horse dung you should find Azelia spinosa Vikhrev, 2015, I'm sure this species is present in France as well.
