The seasonal changes of carbohydrate contents in overwintering larvae of Enosima leucotaeniella were investigated to understand the relationship between carbohydrate contens and diapause. More than eight kinds of sugars and polyols were detected in the haemolymph and body by gas-liquid chromatography. Trehalose was a dominant substance and trace levels of other sugars and polyols appeared during hibernation. From September to January, trehalose content increased with decreasing glycogen in spite of diapause termination in late November, but total carbohydrate (trehalose plus glycogen) content stayed at an approximately constant level. In February, however, both trehalose and glycogen contents decreased.
