Japanese Beetle

Adults are commonly found in gardens, agricultural fields, nurseries, parks, and on golf courses. Larvae live in turf and soil.

Adults are polyphagous and feed on the foliage, flowers, and fruits of over 300 species of plants, including roses, grapes, and many ornamental trees and shrubs. Larvae feed on the roots of grasses and other plants.

As adults, Japanese Beetles are active during the day, feeding on a wide variety of plants. They are attracted to each other by pheromones, leading to large aggregations. Larvae (grubs) live underground and feed on plant roots.

Risks: Japanese Beetles are a significant invasive agricultural and horticultural pest in many parts of the world, causing extensive damage to crops and ornamental plants. Benefits: Though a pest, like all insects, they play a role in the ecosystem; however, their negative impact as an invasive species often outweighs any benefits.
