PARAGOMPHUS capitatus – Gomphidae

The male of Paragomphus capitatus, Gomphidae – Oct 15, 2016

My first encounter with this dragonfly, Paragomphus capitatusGomphidae, on Oct 15, 2016, at Karajae River, Parepare – South Sulawesi. I was surprised, because suddenly they flashed in front of me, when I try to tread the river rocks. At the time it was noon, at 11:10 am. I watched them closely, and it turns out they are familiar, and not difficult to approach.

Perched on the river rocks

I observed their attractive color patterns, predominantly yellow, with many black stripes, but rather green-blue face. They seem happy, chasing each other, even with other species (at that time with Trithemis and Orthetrum). They seem to like the flow of water in the river, but not too heavy. Perched on dry twigs, or on the surface of river rocks, they often looked stylish, with upright abdominal lifting, or twisting the head. They looked like a clean and open space, and shy away from bushes and grasses.

Interesting and rare species, endemic in Sulawesi

I approached them and took some pictures. At that moment, I just found the males. But I was very impressed with this meeting. I noted in my exploration book, some things are important, especially when meeting with them (October), the habitat they prefer, other species join them, and abundance in one location – when I just found 8 dragonflies of this species.
