The gurgling sound of the rocky river breaks the silence of the Sidomulyo jungle. The Blang Kolam waterfall flowing through the Rayap River can be heard faintly from a distance. The Rayap River, filled with rocks, is home to various Sumatran Odonata species.
I noticed colorful damselflies flying low here and there on the surface of the Rayap River. Rhinocypha fenestrata, commonly called the pink-blue jewel, is one of the many damselflies that inhabit the Rayap River environment.
R. fenestrata is a medium-sized damselfly with characteristics of a blue and pink patterned thorax, a black tail, and brown-black patterned wings with pink stripes. This is truly the most beautiful damselfly I have ever seen!
