Found this guy yesterday by a path near a lagoon. Taken in the outskirts of Madrid. Would love to know the species. Thanks in advance for any help.

A lateral view, just in case it helps.

Hope you weren't agreeing with that Paul...Chrysotoxum of some description yes.

On the thorax you can see the 'white stripes' of the specific name - my only doubt was that I wouldn't know about any very similar continental species.

I tend to disagree. The long antenna make it a Chrysotoxum sp. for me.

I think this is Chrysotoxum vernale.

Thanks to you all for your input!

I am sure it is a Chrysotoxum. As Lakeside said, the antenna make it Chrysotoxum.

I have been doing some searching and I agree with Lakeside that might be C. vernale. But I think it can be C. intermedium too. What are the features that separate C. vernale from C. intermedium?

Thanks in advance!

Could be both species in my opinion. I don;t think the difference can be made from these shots...at least not by me :)

Who said Chrysotoxum intermedium ? This is C. intermedium. C. vernale has a shorter 3d antennal article.
