Corduliidae - Idionyx yolanda Selys, 1871
Idionyx yolanda is one of the most common cordulid species in Peninsular Malaysia. Curdulids are characterized by its green eyes and metallic green body. Cordulids are forest species, therefore it is hardly seen them around. I have encountered I. yolanda in a few accasions, but all the encounters are female individuals. So, I have not yet caught a male I. yolanda.
