12mm 20.5.20 in a hedgerow, Wiltshire, UK. I think this is R. tringarius rather than the much more common R. scolopaceus as it lacks the dark wing stigma, but am not sure how to be sure it isn't the extremely rare R. annulatus the only UK confusion species s far as I know. I don't have a better angle on the wings to check the humerus colour.

Definitely not a Rh.scolopaceus.

You are right, Nick, Rhagio tringarius it is - yellow pterostigma and yellow humeral callus are diagnostics for this species. |

I'm concerned about the black femur in the apical part. Could it be a Rh. nonatus? |

No tringarius it is (which is, by the way, more common than scolopaceus these days !). notatus has dark stigma and dark ring in femur 1. Tringarius is extremely variable ! Stop worrying: tringarius ! Theo |
