Do beetles eat native cherries ?

Yes, some species of beetles are known to feed on native cherries. For example, the Japanese beetle (Popillia japonica) is a common pest of cherry trees and feeds on the fruit, leaves, and flowers. Another beetle that can damage cherries is the cherry fruit fly (Rhagoletis cerasi), which lays its eggs inside the fruit and causes it to rot. However, there are also many beneficial beetles that can help control pests in cherry orchards, such as ladybugs and ground beetles.
