June beetle (ten-lined June beetle)

Sandy soils, woodland edges, gardens, orchards, and areas near lights; common in western North America.

Adults feed mainly on foliage of trees and shrubs, sometimes causing minor defoliation. Larvae (“white grubs”) eat roots underground.

Adults emerge in summer, fly noisily at dusk or night, and are attracted to lights. Females lay eggs in soil; larvae develop underground for several years before pupating.

They are harmless to people and do not bite or sting. Larvae can damage lawns, nursery plants, and crop roots, while adults serve as prey for birds, mammals, and other predators.
