Hi, I found this on wet marshland near the Thames in south Oxfordshire, England. Is it Chrysotoxum cautum?

Thanks, Chris R.

Yes, it's a female C. cautum.

Hello,



Chrysotoxum cautum or C verralli ?

I do not have the keys to separate these two species just using a photograph.

South downs, north Shoreham, Sussex
