The life history of a leaf-miner, Nepticula castanopsiella, infesting the evergreen leaves of Castanopsis cuspidata, was studied with a view toward its host-parasite relationships and the relationships to its environment. The life history of this species was characterized by diapause in summer and feeding in winter. This mode of life may be established by the following factors in the adaptive process. The eggs show temperature dependent diapause in summer when the temperature is relatively high especially for leaf-miners and when the natural enemies are active. The larvae begin to feed on food leaves after autumn when the leaves have become rich in nutrients. The leaf-miner favors the thermal conditions of its microhabitat by keeping the mine temperature higher than that of the outside during the cold season. The winter feeding of larvae was supposed to decrease the mortality of the leaf-miners by parsites. These things were supported by population dynamics, characteristic adaptations for temperature and bioeconomic properties.
