This study was conducted to investigate the life history of Compsidia populnea which was major species of the stem-borers on Populus alba x glandulosa. Peak emergence of the adult of Compsidia populnea L. was around 10th-12th of May in Chunchon vicinities, having one generation a year in Korea. There was a preovipositional period of 10.7 days and a ovipositional period of 14.3 days. Mean adult longevity was 11 days for male and 13.8 days for female. Individual eggs were long oval with 11 days and 13.8 days for female. Individual eggs were long oval with somewhat narrowed tip at one side and soft, 2.6mm in length, 0.8mm in diameter, and were laid singly under the U-shaped scars which were made by females before oviposition
