Rhinocypha humeralis Selys, 1873 Photo taken in Sabah (Malaysia) on 2007-08-10
The genus group of Rhinocypha are rear damselflies. All but 1 of the 8 species Rhinocypha in Borneo Island are endemic found only locally. So is their ‘face’ unique from other species of damselfly. (The one not endemic to Borneo is this species Rhinocypha humeralis )
This male Rhinocypha humeralis has a long extended frons (front of the face) that make it look like a cute puppy dog.
Rhinocypha humeralis Selys, 1873 Photo taken in Sabah (Malaysia) on 2006-11-05
Picture 1: A pair of Rhinocypha humeralis copulating in a forest reserve in Sabah, Malaysia.
Rhinocypha humeralis share their territories with few other damselflies species. In this photograph are a pair of copulating Rhinocypha humeralis (right below) and a pair of Pseudagrion pilidorsum (left above).
We can easily see both male and female Rhinocypha humeralis as they like to perch on bright sunny spots on tips of fern plants. But suddenly out of sight when they copulate because they descent to shadow dark corner below the vegetation.
This pair of Rhinocypha humeralis in the photo is only two feet above slow running stream water.
