Diplacodes trivialis (blue percher)
Family libellulidae
Being the tiniest drangonfly, similar to acisoma panorpoides panorpoides (Asian pintail), the Diplacodes trivialis (blue percher) is a regular tenant of Niaosong Wetland Park. The male dragonfly has a grayish blue chest and blue compound eyes; while the female is yellow. Unlike the other dragonflies, the blue percher only swells in the third abdominal segment.
