Swollen-thighed Beetle Oedemera nobilis
Another commonly-used vernacular name for this species is Thick-legged Flower Beetle.
Males of this species are very easy to identify but I sometimes struggle a bit more with females. I've been misled by some of the comments in keys about lurida not having a clear gap between the elytra and suspect I have misidentified the odd lurida as nobilis. I think all I've included here are ok (but please do shout if you disagree).
