where do japanese beetles live in the united states
Japanese beetle As the name suggests, the Japanese beetle is native to Japan. The first written evidence of the insect appearing within the United States was in 1916 in a nursery near Riverton, New Jersey.[3] The beetle larvae are thought to have entered the United States in a shipment of iris bulbs prior to 1912, when inspections of commodities entering the country began. As of 2015, only nine western US states were considered free of Japanese beetles.[4] Beetles have been detected in airports on the west coast of the United States since the 1940s, but it was not until 2016 that populations were found in suburban and agricultural areas outside of Portland, Oregon.[5]
