The below Singapore latest definitive stamp (45c) has micro-printing. The words "Ornate Coraltail" are printed on the wing of the damselfly.
The damselfly species depicted on the 45c-stamp is Ceriagrion cerinorubellum. Below is a photo showing Ceriagrion cerinorubellum in the same action as that of the 45c-stamp - having sexy fun.... hehehehehe
