Japanese Beetles are a significant pest of roses, causing damage to leaves and flowers. They can be identified by metallic green body and copper colour wings. They are oval in shape and have white tufts of hair along the sides and bottom of their bodies. The larvae are creamy white, with a brown head and can be found in soil.
Adults emerge from the soil in the summer and feed on the leaves, flowers and stems of roses and other plants. They lay eggs in the soil, which hatch into larvae. The larvae feed on plant roots before pupating in the soil and emerging as adults the following year.
Japanese Beetles are foliage feeders and cause significant damage to the leaves of rose plants.
Scientific Name: Popillia japonica
