Question: something is eating the leaves on my snowball bush?
Answer: Viburnum leaf beetle (Pyrrhalta viburni) is the insect causing this "shot hole" feeding on your snowball tree (Viburnum opulus 'Roseum'). ... The insects emerge in May as caterpillars, mainly on the underside of leaves. In early summer, the larvae drop to the ground and emerge as an adult beetle by mid-summer.
