Selected images for citrus longhorned beetle (Anoplophora chinensis )
Citrus longhorned beetle is native to Asia and occurs primarily in China, Korea, and Japan. It has been found in, and eradicated from, Georgia, Wisconsin, and Washington. It was most likely introduced on wood packing material or in live plant material. It is known to attack and kill more than 100 species of plants and includes several species in the Citrus genus as well as peach, cherry, pecan, maple, oak, ash, elm, and walnut. Larvae are white, opaque, legless grubs typical of longhorned beetles. When mature, they are 1 3/4 to 2 1/3 inches long and about 1/3 of an inch wide with an amber colored head and black mouthparts. Adults emerge from April to August. Adults are 1 – 1 1/2 inches long and shiny black with white markings. Antennae are at least as long as the body and have alternating black and white bands. The ventral surface is pubescent. The color of the pubescence varies from white to blue depending on location. An important identifying characteristic of Citrus longhorned beetle is the presence of two pairs of polished white bumps at the base of the elytra. These are visible with a 10x hand lens and are not present on the Asian longhorn beetle, Anoplophora glabripennis. Damage includes distinct round or slightly oval shaped adult exit holes on the bark surface, T-shaped oviposition holes, sawdust-like frass or wood pulp around small holes, and larval tunnels in the wood under loose or thin bark.
