In the Kaname River system, habitat differentiation between two odonate species, Davidius fujiama and D. nanus , can be observed. In adults, D. fujiama lives in forested areas along the upper stream, and D. nanus lives in open areas along the lower stream. The adults mate and oviposit along the watercourses of their respective habitats. The difference of oviposition may result in naiad habitat differentiation, which is, however, not so distinct and their respective habitats overlap in the boundary area. The naiad habitat extends downstream from the oviposition area in each species. The naiads may be transported by strong water flow sometimes caused by storms.
