Abstract
We studied the spatial distribution patterns of various types of domatia on Cinnamomum camphora Linn. leaves and the seasonal occurrence of eriophyid mites inhabiting the domatia. At the time of foliation in the spring, the domatia on the leaves at the proximal part of shoots had a wide-entrance, while that on the leaves at the other parts had a narrow-entrance. With the advance of foliation, the peak density of eriophyid mites shifted from previous-year leaves to current-year leaves, and from proximal to distal parts of the current-year shoot. Eriophyid mites increased in number at the domatia with a wide-entrance early in the season, and later they seemed to migrate to the domatia with a narrow-entrance.
