Pyrrhalta viburni is a species of leaf beetle native to Europe and Asia, commonly known as the viburnum leaf beetle. It was first detected in the United States in Maine in 1994.[1] The UK-based Royal Horticultural Society stated that its members reported Pyrrhalta viburni as the "number one pest species" in 2010.[2][3] Female beetles burrow into viburnum twigs and create 'spaces' in pith tissue. Then they lay eggs in clusters of covering them with frass. Eggs overwinter in these cavities where they are protected from water loss and being consumed.[4]

The spined soldier bug, Podisus maculiventris is used and developed as a biological control agent against the beetle.[1]
