The Asian long-horned beetle (Anoplophora glabripennis), sometimes called Starry Sky (Sky Oxen in China) beetle, is native to China and other areas of eastern Asia, where it causes widespread mortality of poplar, willow, elm, and maple trees.

Asian long-horned beetles are big, showy insects: shiny and coal black with white spots. Adults are about 1 inch (2.5 cm) long. On their head is a pair of very long antennae that are alternately ringed in black and white. The antennae are longer than the insect's body.

An invasive species in the United States, the larvae of this beetle have a voracious appetite for wood. It is especially damaging to maple trees: Norway, sugar, silver, and red maple are among its preferred foods. The species also feeds on horse-chestnut, poplar, willow, and elm. Females of this species chew into the bark and lay eggs. When the eggs hatch, the immature beetles, which look like big white worms, chew their way farther into the tree. When they mature, the full-grown beetles chew their way out of the tree. The beetle life cycle leaves trees riddled with holes, oozing sap. The USDA believes this beetle can probably survive and reproduce in most sections of the country where suitable host trees exist. The beetle has also invaded Britain, Austria and Germany.
