Scientific Name: Pseudothemis jorina
Common Name: Banded Skimmer
Banded Skimmer is an uncommon species of dragonfly in Singapore. I have seen this species at many locations such as large open water bodies at lower pierce reservoir; large ponds at the Singapore Botanic Garden; at the forest fringes of Bukit Timah Nature Reserve; Chestnut forest, and Ulu Sembawang Park Connector etc.
The male is basically black with white marking on the 1-3 segments of the abdomen. The female is yellowish with dark markings. Males are often found flying rapidly at open ponds and reservoirs, sometimes chasing rival males. By noon and after, it becomes less active and can be seen perching on twig in the forest. Sometimes, several males can be seen flying in swarm at the fringes of the forest.
Female is rarer, less active and most often encountered inside closed forest.
