星天牛（学名Anoplophora chinensis）是中国、**、韩国、及日本特有的一种天牛，一般都被当地认为是害虫。

成虫体长19－39毫米，宽6－13.5毫米，身体漆黑有光泽；鞘翅上有白色毛斑约20个，呈不规则横列；老熟幼虫体长45－50毫米，淡黄白色扁圆筒形。

年生一代；雌性星天牛一次可以产达200颗卵，而每颗卵都会被分开藏在树皮中。当幼虫孵化时，它会咀嚼入树内，造成一条信道用来结蛹。由产卵至结蛹及成虫为期可以达12-18个月。

危害 星天牛的虫患可以杀死多种不同的硬木树，如柑橘属、山核桃、苹果、木麻黄属、木槿属、无花果、柳树、梨、桑树、木豆、苦楝、杨属、荔枝、金橘、日本柳杉、橡树及榕属。

The citrus long-horned beetle (Anoplophora chinensis) is a long-horned beetle native to Japan, China and Korea, where it is considered a serious pest.

Each female citrus long-horned beetle can make up to 200 eggs after mating, and each egg is separately deposited in tree bark. After the beetle larvae hatches, it chews into the tree, forming a tunnel that is then used as a place for beetle pupation (the process of growing from larvae to adult). From egg-laying to pupation and adult emergence can take twelve to eighteen months.
