 note = {application/pdf, In order to clarify the population dynamics of the damselfly, Calopteryx japonica, the mark-release-and recapture method was used for the population inhabiting in a small river in cool temperate zone of Japan, 1989 and 1990. The survey on the distribution of each adult perching was also carried out. The estimated daily number of males was 500 (1989), while that of females was 480 (1989). Then the operational sex ratio in each year was likely unity. The daily estimate number of immigrants in each year was low, and the daily survival rate was high. Therefore, the populations in both years were considered to be a closed population. The perching site of the damselfly depended upon the sunlit area on the shore line of the river. Along the shore line the perching site of males was shown as a clear random distribution, due to the territorial behavior. The survey curriculum provided the basic understanding of concepts on mark-release-and-recapture method for high school students as well as undergraduate students. The damselfly used in this study allowed for the application and extension of the skills and knowledge of field ecology. These results were discussed as a teaching material for the damselfly in view point of the environmental education.},
