Your images are not being displayed. Usually this is either because they are too big (over 195k) or the filenames contain disallowed characters (must be letters, numerals, hyphen - or underscore _ only). |

Welcome, Anna!!   I am inclined to think this is a female Eristalis similis, but I cannot see enough detail to be sure. Definitely, I cannot see the engrossed hind tibiae and the double vertical bands of hairs in the eyes, typical of Eristalis tenax. No enough detail to see if there are hairs on the aristas of the antennae either, which would be definitive. But I think I can see the long pale pterostigmas of Eristalis similis. I fear my sight might deceive me though. I'd rather wait for more opinions. The other species of Eristalis found in Spain, simply don't fit with yours at all |

Well, if my sight doesn't deceive me I can see two vertical lines on the right eye now. Not very clear though. But the aristas are not pubescent and are ridiculously long for similis. All that fits with tenax. I am surprised that the hind tibia doesn't look engrossed in the second picture. It must be the angle. Pterostigmas look pale but are definitely short. I think it is another trick of the light and the angle. Should be Eristalis tenax, but features are not completely clear. I would name it Eristalis cf. tenax |
