Pseudagrion microcephalum - Submerged Oviposition

I spotted a tandem pair of Pseudagrion microcephalum laying eggs at a pond at late afternoon. While the female was laying eggs above the surface water (on aquatic plant) with the male still attached in tandem to it, a male Brachythemis contaminata came suddenly to grab (preying) the male Pseudagrion microcephalum. So, the Pseudagrion microcephalum male was detached from the female. However, the female was untouched by the sudden act, and remaining at the same spot continuing to perform egg-laying. After a while, the female submerged into water to continue laying eggs (see below photos). At one time, the whole body including the wings was totally under the water.

Larva - Pseudagrion microcephalum

The normal aquatic habitat for Pseudagrion microcephalum is open ponds or open marshes. I have seen frequently the larval emergence of P. microcephalum took place at late afternoon. Below photo shows a larva of P. microcephalum out of water on a waterlily leaf ready for larval emergence. The photo was taken around 5.30 pm at a pond.

Pseudagrion australasiae vs Pseudagrion microcephalum

The blue markings of the male individuals of Pseudagrion australasiae and Pseudagrion microcephalum are quite similar to each other. However, Pseudagrion australasiae is slightly larger than Pseudagrion microcephalum. Apart from that, their anal appendages are different as shown in the diagram below:
