Dragonflies of TAIWAN

The postal authority of Republic of China (Taiwan) issued beautiful dragonfly stamps and souvenir sheets in three series. Series I was issued on October 11, 2000 depicting dragonflies found at forest stream; series II was issued on July 25, 2003 depicting dragonflies found at pond; and series III was issued on August 16, 2006 depicting dragonflies found at paddy field. Different aquatic habitats have different dragonfly species. Altogether 12 species of dragonflies are shown on the stamps and souvenir sheets. Taiwan has more than 120 dragonfly species. These dragonfly stamps are unique because different behaviours of the dragonflies are displayed on the stamps - perching (resting), hovering (hanging on the air), egg laying, courting (the female is guarded by male particularly during egg laying) and mating.
