Pseudagrion pruinosum

I witnessed partial submerging oviposition of Pseudagrion pruinosum. I believe in rare occasion it will do a total submerging oviposition.

P/S:
I searched the internet for information on the egg laying of Pseudagrion pruinosum. So, it has been recorded that Pseudagrion pruinosum does total underwater oviposition with the male individual also down into the water. Click here for the paper about the egg laying of Pseudagrion pruinosum

Oviposition of Vestalis amoena

I observed the mating of a pair Vestalis amoena by the shore of a stream (Sg Durian). Right after the mating, the female was laying eggs on the leaf substrate in the stream. The male was perching at another leaf to guard the female.
