I know that maybe is impossible with this photo give a name to this fly. I can't made a better photo. It was in January 2007 in a rosemary in my garden, Zaragoza, Spain.

Any suggestion is welcome.
Regards ;)

Well, the jizz of this fly suggests rather a Limmoniid crane fly. The photos are not really focused, so the id will not be easy for anyone.

Thanks Xespok!
But... Limoniid? I think, is too small for a cranefly. I don't tell the size, but is easy see it with the rosematy leaves. It sizes 22-25 mm. from head to wing tips. The month of apparition (January) and the very long legs suggest me a Trichoceridae...

More opinions?

The variation in size in Limoniids is immense. The smallest Limoniids are dwarfs as compared to Trichocerids, while the largest ones are in fact larger than any or at least the vast majority of Tipulid crane flies (in Europe). So do not count on size being a good indicator o separate Trichocerids from Limoniid crane flies. The average Trichocerid and Limoniid is roughly the same size.

Also time of occurence is little informative, most Trichocerids are not found in the winter, and some Limoniids are found during the winter, particularly as far south as Spain.

The legs seem to be too long and the antennae too short for this image to show Trichocera sp in my opinion.

Thanks again!

In that case, it's a Limoniidae... but it can be almost impossible tell the species, or even the genus, I suppose.
