Abstract: In order to understand energy storage of Dryomys nitedula before winter, and provide information for artificial feeding, behavior and activity pattern of D. nitedula pups were observed indoors by infrared motion sensor cameras． Specifically, from June to September, cameras which can collect the activity data of the animal for 24 hours continuously were fixed on the tops of cages．Results showed that,the pups of D. nitedula spend about 70% of a day in the nest, where they huddle together with rare activities, Most play-behavior occurred outside the nest - for example, climbing on the cages．The time spent on feeding activity was no more than 2% of the whole day．The major activity time of the pups happened between 21:00 pm to 07:00 am, and reached its peak at 21:00 pm to 03:00 am．Three weeks after birth, the pups starts to play outside the nest; after 30 days they start to eat food;and after 5 weeks play and mating behaviors of emerged．Along with increased day-length, the activity peak was changed from 23:00 pm to 21:00 pm, the total activity time also increased gradually, but the activity time then gradually shortened after 9 weeks of age, and the time of feeding behavior on food and water were consistent with other activities．The body weight at 10 weeks age was almost 70% of that of the adults．The results revealed that D. nitedula is a nocurnal animal during the summer and autumn．Light is one of the important factors that can influence the outside activities of D. nitedula．The amount of food and water consumed by the D. nitedula pups at 6 weeks of age was more than of the adults, which indicates that supplemental food and water should be added at this period．
