Very high chances to be right! It's a female, but I bet you already !

Thanks Valerio!
I'd like to be as sure as possible before logging this observation.
As far as I know, the only Chrysopilus in the British List are asiliformis (aureus), cristatus (auratus), erythrophthalmus and laetus
I think the latter 2 are quite rare.
I thought this one was asiliformis based on the pale femora.
Here is another shot it from a slightly different angle.

Regards,
Martin

You're right. Legs + thorax are quite useful to distinguish this species from C. cristatus. And this female is asiliformis.

Oops...I was writing "It's a female, but I bet you already knew it". But while I was modifying the text I made some catastrophe :)
