Rosama sp. Is a Lepidoptera, Solenidae family, species to be determined. Lime rust moth is a large leaf insect pests. In recent years, Liaoning Province, Faku County, Ding house, Shuangtaizi, red May Township and other places is particularly prevalent, the damage is very rampant. According to the incomplete statistics in 1981, only 200 mu of Lespedezae leaves were eaten in Daquanyan Village, Dingjiafang Township, resulting in the withered branches and shoots of the affected branches and broom-like after they grew again. Seriously affect the quality and production of the bar. In order to understand the biological characteristics of this pest and its occurrence in the Faku area, its life history and living habits were preliminarily observed in 1982. The results are now organized as follows. First, the morphological characteristics 1. Adult: body length 12-17mm, wingspan 30-35mm.
