Green June Bug

These metallic green insects are nearly one inch long but start their life cycle as a grub in the soil. Green June beetle larvae are edible (Lion King movie, anyone?) and often found in the ground and on sidewalks and driveways around the home. Adult beetles feed on the foliage and fruit of trees in mid-summer, usually causing damage to the foliage similar to that of Japanese beetles, just not quite on the same scale. They are particularly fond of peaches, plums, and grapes. Grubs feed on decaying organic matter and the underground portions of plants such as sweet potatoes and carrots. Unlike other grubs, these insects do not cause damage to the turf other than the tunneling they do. On a unique note, Green June beetle grubs have been known to feed on Japanese beetle grubs and cutworms, so there is some thought they could have a beneficial impact. Usually, control is not needed for these insects. However, the grubs are susceptible to carbaryl sprinkled on the soil surface (don’t water it as it comes to the surface), unlike other grubs in the soil. The adults can be easily caught or knocked into a bucket of soapy water if they are a nuisance. These insects are attracted to overripe fruit, so pick fruits as they ripen to reduce the chances the adults will visit your orchard.
