Platystictidae - Drepanosticta quadrata

Platystictidae - Drepanosticta quadrata (Selys, 1860)

Family Platystictidae contains mainly forest species, and most of them are found to be endemic. Among the few species of Platystictidae recorded in the Peninsular Malaysia, Drepanosticta fontinalis is the most common one. Orr (2005) stated that D. quadrata is known only from Singapore Island.

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.
