A small black fly on my balcony, hiding from the cold.
Minas de Riotinto, February 6, 2025.

Any idea?

¡Gracias!

Yes, that could be. I will look into Muscidae and see what I can find.

Thanks again, John!

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. TumbsUp

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!

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.

You guys are incredible!!!

Nikita, thank John Sherkosky for the ID of my fly. TumbsUp
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! Smile

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