The infestation of the clearwing moth, Synanthedon haitangvora Yang, has become heavier in the organic and ecological apple orchards in Beijing. The morphology of the adults （including male genitalia）, larvae, pupae, and its life history were investigated. It occurs one generation per year and overwinters as the larvae in co- coon under the bark. The adults emerge from the end of May to the end of July. The diagnostic characters of the closely related species, application of sexual pheromone and other control methods were also discussed.
