Bugs eating my camellia

Tall trees

Can anyone tell me what’s eating the leaf edge on my camellias, I’m in South Wales.

Caterpillars or weevelis?

That mostly looks like vine weevil damage. 
A healthy shrub like a Camellia will shrug that off. It's the grubs that do most of the damage to some plants underground, by eating the roots. Things like Heucheras are susceptible. 
In most cases, it's aesthetics when it's the adult damage. Camellias aren't likely to be bothered other than that. If you have weevils in the garden, you'll get a bit of damage on other shrubs too
