Ecology and description

Yambaru flatwig is a small damselfly with a body length of about 4 cm. It was previously considered a part of the Okinawa flatwig (Rhipidolestes okinawanus) population. However, the population in northern Okinawa has now been recognized as a new species, Yambaru flatwig, whereas the Okinawa flatwig is found south of Henangawa river. The species name is dedicated to the odonatologist Shozo Ishida.

The distribution of Yambaru flatwig is very limited, found only in the upper reaches of streams. Although adults appear in summer, due to their small size, they are not easily observed.
