Help: why is my Shrub dying?

I have a tall shrub which has been slowly dying. Any new leaves are quickly eaten and then turn brown.
Any help to understand why?

 

It's Viburnum beetle larvae

Look under the new leaves and you should see this (very tiny), there is also black larvae as well


Best way to is to spary them now and try and break the life cycle

Your shrub will come back, you also may notice a smell about when damp
