Is this vine weevil on my new deciduous azalea

at your picture I'm 99.9% sure (and sorry to say) its adult Vine Weevil damage. Holly is also susceptible to attack from Vine Weevil, and Primula's even more so. The larvae will be feeding on the roots.

A good application of Nematodes (follow this link ) will help reduce further attacks as they parasitize the soil dwelling larvae, but also good hygiene around the affected plants by means of clearing away dead leaf litter etc and cultivation of the surrounding soil. You can also collect and dispose of adults from the plants if you wish which is usually best done during dark hours with a torch.

Many thanks for your query, and good luck.

Kindest Regards
