The first was Prodasineura humeralis. It is quite common in Peninsular Malaysia but in
After about 10 minute’s copulation, the pair flew down to the stream and the female started ovipositing.
After a while, the male released his grasp and the female descended underwater.
The video clearly shows the female searching for ovipositing spots with her abdomen. She surfaced and flew off easily due to the fact that her forewings remained dry thanks to it being shielded by the closed hindwings.
Whilst the female was submerged, the male waited nearby on a leaf. The instant she surfaced, he grasped her again in eagerness for another round of mating.
This is the first time I witnessed such behaviour and am suitably thrilled. According to literature, underwater oviposition occurs only in endophytic odonates in particular the damselflies but this ovipositing mode is not a compulsory with regards to any particular species. Some advantages of underwater oviposition include exemption from interferences from males and protecting the eggs from desiccation.
Studying odonates has honed my patience and observational attributes. I eagerly anticipate the next exciting observation in the field.
