Survey on Odonata - Kajang 2

There is a nice pond at Kajang 2, Selangor. The pond is located next to Kajang 2 Villas. It looks like the pond is well managed by the MKH Developer. The pond is open to public. A walk path is available around the pond for public to have a nice walk. The pond also attracts fishing hobbyists to do their fishing activity there. I did an Odonata survey at the pond on 4 January 2025. A total of 14 species of Odonata were recorded - 3 are damselflies and 11 are dragonflies.

Orthetrum glaucum vs Orthetrum luzonicum

It is quite a challenge for laymen to tell apart Orthetrum glaucum from Orthetrum luzonicum because both (matured males) are light blue in colour. Actually, we are still able to distinguish them if we look at them carefully. Orthetrum glaucum is slightly larger than Orthetrum luzonicum. The hindwing base of Orthetrum glaucum has dark patch, but this is absent in Orthetrum luzonicum. Apart from that, the abdomen of Orthetrum luzonicum is slightly slender if compared to Orthetrum glaucum.

Archibasis rebeccae

I saw this Archibasis rebeccae female performed an act to grab a small spider resting on its net. The Archibasis rebeccae approached the spider net skillfully so that it was not stuck herself on the net of the spider. Hovering at the same level as the spider (the spider net was at the vertical position), she suddenly pushed forward her legs to grab the spider and then retreated herself away from the vertical spider net so that she did not crush into the spider net.

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.
