I thought I was shooting an Ulidia when I took the picture, but once at home I realised the venation doens't match. Can it be a Syrphid? Cheilosia, perhaps? I am puzzled. Thanks in advance for any help.

Taken in the mountains of Madrid on the 21rst may 2011.

No I think it's not a Syrphidae. Smile

Looks like a female of Chrysogaster (Syrphidae). However, the only species I know, C. solstitialis, has darkened wings. So we need the help of Syrphid experts.

From how I can see it, it seems to have black antennae. That would make it a Melanogaster. It probably is M. hirtella.

OMG! I didn't pay attention to the antennae. Does the female Melanogaster hirtella have that peculiar wrinkled frons like Chrysogaster solstitialis? I cannot find any pictures where I can see that feature.

And thanks once more, Andre! Hope you got loads of interesting syrphids in Portugal Wink

There are photos of female Melanogaster that show a wrinkled frons! Look here: http://www.flickr...0559346/#/Grin. A click on the image brings you to a selection of higher magnifications.

Yes, it was quite interesting indeed, with several new species for the fauna again and some nice additions too.

PS: go back and collect some, males and females, please. Kill them in the freezer and send them. It can be quite interesting Smile
