I'm sure that this photo may not be of much help.
It is the only one I was able to take of this beautifull fly. The first thing that took my attention were its eyes, therefore I just shot as close as I could.
She/he gave me no more chances, but what I do remember is the "body" was slender, darkish-blue and sizing abt 1 cm. She mas buzzing arround my garden in an urban area.
Photo taken at Vigo (Spain) sealevel, midd-may 2007.-
Thanks once again for your patience.

Stratiomyidae.
Hermetia illucens. I have a similar photo here

It is very curious because today in the field I saw Asilidae eating a ... Hermetia illucens!!!

It has transparent abdomen. IT looks like two tiny windows.

(take off the wings and take a look to dorsal abdomen in anterior part)
