Viburnum beetle was named as the number one pest by the RHS in 2010, stealing the crown from slugs and snails. It's native to the UK, but is becoming more widespread. Most of the leaf damage is caused by the stripey, beige-coloured larvae, though later in the year adult beetles emerge, worsening the problem.
Symptoms
Holes in the leaves of viburnums caused by the larvae and adults of viburnum beetle. Plants can be completely stripped of foliage and can emit a foul smell, which is thought to be caused by the excrement of the larvae.
