Vine weevil. The adults, all female, do the chewing of the leaves, particularly rhodos, bay, but many other things too, while the grubs are chomping away at their favourites, the roots of primulas, heucheras, saxifrage in pots. The adults are night time feeders, so go out and hand pick them, or shake them out in the daylight. They play dead, so be aware. The scourge of the pot stock.

Thank you very much, I will treat it accordingly. Thanks for prompt response.
