Pseudagrion australasiae - Submerged Oviposition

I have seen underwater oviposition of Pseudagrion australasiae on a few occasions. The female totally submerges into water for oviposition. At the beginning of the oviposition, the male is attached to the female while the female retreats slowly down into the water. Later on, the male is detached from the female, leaving the female in the water. However, the male guards above the water throughout the whole process of underwater oviposition of the female. The underwater duration for the female may last for more than 10 minutes.

Dragonflies and Damselflies of Tasik Ghazali UKM

Tasik Ghazali in Campus Bangi Universiti Kebangsaan Malaysia (N2°55’19” E101°46’54”) is a good site for dragonfly watching. The small lake is located by the road side. You may click here to see a video of Tasik Ghazali produced by UKM. I did a field survey at the site to record the dragonflies/damselflies at Tasik Ghazali on 9 June 2024. I managed to record 31 species on that day (from 10 am to 7 pm).
