Larva - Ceriagrion cerinorubellum

Ceriagrion cerinorubellum shares a same aquatic habitat with C. chaoi in Bangi Forest Reserve. The larvae of cerinorubellum and chaoi are extremely active but both can be differentiated easily by the shape of the gills. Below is the larva of C. cerinorubellum. It is still surviving in the aqaurium.... I'm breeding it........

Larva - Potamarcha congener

I caught some larvae of Potamarcha congener from a standing muddy shallow water exposed to sun near forest edge. I only know about its identity after one of the larvae emerged a few days ago.

Libellulidae - Aethriamanta brevipennis

Aethriamanta brevipennis is one of the most striking red colour dragonfly species. It is a medium size dragonfly normally found at exposed ponds and lakes. It is not a common dragonfly species. So far I have only encountered it at the pond adjacent to Bangi Forest Reserve.

Libellulidae - Zyxomma obtusum

I was late in my office last night. I was about to leave my office building, and I spotted this guy (Zyxomma obtusum) flying around the light in the building. It was the second time I bumped into Zyxomma obtusum. Compared to Z. petiolatum, Z. obtusum is less common in Peninsular Malaysia. Both the Zyxomma species are crepuscular species.

Larval Emergence - Ceriagrion chaoi

I managed to record the larval emergence of Ceriagrion chaoi...... this larva was bred in a small acquarium, and I placed some rock onto the water. The larva climbed up the rock at noon and slowly emerged.......
