Common Name: Japanese Beetle
Order: Coleoptera Family: Scarabaeidae Pest Status: Japanese beetles are serious pests of turfgrass when they are grubs and also serious pests of many plants (trees, shrubs, flowers, fruits, and agronomic crops) when they become adults. Appearance: The Japanese beetle is about 1/2-inch long with shiny copper-colored wing covers and a shiny green top of the thorax and head. The abdomen has a row of white hair tufts of hair on each side. Life Cycle: The larvae overwinter in cells beneath the soil surface. In the spring, the larvae move upward to complete feeding and to pupate. Adults emerge from the ground in mid-summer and the females deposit their eggs in the soil. The eggs hatch about two weeks after deposition, normally between July and August. Where to Collect: The adults are general herbivores and can be found on all types of plants. |
