Hi,

As far as I know it belongs to the family Rhagionidae. Unfortunately I cannot tell you a species or even genus name. Let's wait for the others:).

Thanks, Jan for the right track :)

Could be Rhagio tringarius?

I think this is not R. tringarius. R. trinagrius is the most common R. species in Hungary, and it has clear wings, not spotted like the R. sp. on your images. See my web site for male and female R. tringarius. Of course I can not entirely rule out the R. tringarius has spotted wings in Spain, but it is quite unlikely.

Thank you, Gabor
I wold try to obtain a Rhagionidae key, can anyone help me?

Gabor is quite right.
It is a very nice picture of Rhagio strigosus, features:
* spotted wings
* pleurae partly yellow
* third antennal segment very short (shorter than second).

If you are looking for a key, start with Tierwelt Deutschlands (that is, if you can read german). Cheap, for instance at www.insecta.de.
I know, it's old, but for this family still a good start.

OR the British key by Stubbs (Soldier flies and allies).
However, much less species treated in there.
