Asian Longhorned Beetle (Adult Male)

The invasive Asian longhorned beetle (ALB) is shiny black with white spots. The antennae are long and have alternating bands of black and white. The antennae are usually 1 to 2 times greater than the length of the body. The upper sections of the legs are whitish to blue. The ALB should not be confused with the cottonwood borer, a native longhorned beetle, which has a more even mix of black and white patterns on its body and has solid black antennae.

Asian Longhorned Beetle Larva

ALB larvae are yellowish-white, wormlike, cylindrical, and fleshy, with a varied texture on the underside.

The preferred trees of this invasive species include nearly all our maple species, as well as horsechestnut, black locust, elms, birches, willows, poplars, and green ash.
