Pseudagrion rubriceps - Oviposition

I witnessed the underwater oviposition of Pseudagrion rubriceps (see below).  Before the underwater session, the female (attached to the male) was seen laying eggs above water. She retreated slowly into the water along the water plant stem while ovipositing all the way down under the water. The male was attached to the female during the whole process of underwater oviposition. The duration of the underwater session was 32 minutes.

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.
