September River
Sympetrum kunckeli (Selys, 1884), a small yellow reddish dragonfly with red autumn maple, began to occupy the grasses along the river bank. Without thinking about it, the small yellow dragonfly is one of the smallest dragonflies. It has become quite common in recent years due to the improvement of water environment.
