A small black fly on my balcony, hiding from the cold. Minas de Riotinto, February 6, 2025. Any idea? ¡Gracias! Andre Burgers attached the following image:  [289.88Kb] Edited by Andre Burgers on 12-02-2025 17:02 errare humanum est sed perseverare diabolicum |

The anal vein appears incomplete and the hind tibia is weakly bristled compared to Anthomyiidae. The black color and small calypters have me thinking of the Azeliini. If it is in that tribe Nikita Vikhrev should recognize it. And he doesn't. The three strong anterior spines on the fore femur are found in some Fannia. This is not a Fannia. |

Thanks, John, for this clear information. I'll study these characteristics and try to figure things out. It's going to be difficult, since you two experts haven't reached a conclusion. ¡Saludos! André errare humanum est sed perseverare diabolicum |

Today morning I've got e-mail from John Sherkosky who present himself as "Calliphoridae and polleniidae expert as a hobby" Rather expert than hobby, because he gave me answer with which I quite agree: His answer is: Oplisa atterima, Rhinophoridae !!!

I like that. I convinced myself the M vein looked incomplete because of a torn wing. It really is incomplete, as often happens in Rhinophoridae. |

Looking at good photos I filled myself as a madman. What a pleasure to know correct answer!

You guys are incredible!!! Nikita, thank John Sherkosky for the ID of my fly. One of the problems with this fly was its colour, almost pure black. Difficult to observe structures. But you did it! Again, thanks to the three of you! ¡Saludos!

The strong hairs on basal part of costa are a big clue, once you have spotted them Theo |
