A few possibilities here

Several suggestions here. Anyone able to comment on what sort of features I should be considering?

Jizz...

I was asked the other day what made me think a particular beetle was what I thought it was - I couldn't come up with a satisfactory answer! It usually comes to down to the jizz of the beetle.

Crepidodera are a distinct genus in the British fauna - the thickened hind femora, metallic sheen and parallel body all suggest this genus (which is in the Tribe Alticini as stho002 suggests)

It looks like C aurea, although I really don't like doing these from a photo :-) - foodplant (Populus) fits though.

Thanks

Jizz is often the answer when you get used to a group. I find my self having problems now when people ask me why a particular moth is what I say it is when the most honest answer is "because it looks like one".

Thanks for the extra information here.

Multiple answers?

Note that all of the above answers are consistent except for Chrysolina (which the beetle certainly is not!) The answers are just given at different levels of classification, i.e. Crepidomera belongs to Alticini

Thanks

Currently Chrysolina is the likely ID based on agreements. Beyond me to express a view one way or the other.
