Rammeacris kiangsu Tsai is an important forest pest in China, and causes serious harm to bamboo production. It is univohine, and overwinters in soil as eggs through its distribution area. The observation of embry- onic development was made by using the population collected from Taojiang, Hunan. It was proved that the embry- onic development could be divided into 10 stages. The blastokinesis of R. kiangsu might belong to anatrepsis, and it occurred primarily
