Dragonflies and damselflies (Odonata) are a group of aesthetic aquatic insects. Over 420 species of Odonata have been recorded for Malaysia (Peninsular Malaysia, Sabah and Sarawak). They are waiting for me to explore.

Survey of Odonata at Tropicana Heights, Kajang
Tropicana Heights, Kajang has a retention pond. The pond is well managed by the Tropicana Developer, and it is to public. A walk path is available around the pond for public to have a nice walk. I did an Odonata survey at the pond on 6 February 2025. A total of 20 species of Odonata were recorded - 4 are damselflies and 16 are dragonflies. Brachythemis contaminata and Crocothemis servilia were found in abundant there. I was delighted to see Indothemis limbata (only a few individuals) there.
