Agriocnemis pygmaea[3] (pygmy wisp)[4] is a species of damselfly in the family Coenagrionidae.[5] It is also known as wandering midget, pygmy dartlet or wandering wisp. It is well distributed across Asia and parts of Australia.[1][6]
It is a small damselfly with black capped green eyes, black thorax with apple green stripes on lateral sides. Segments 1 to 7 of its abdomen is black on dorsum and pale green on ventral half. The remaining segments are orange-red. Very old males may get pruinosed on the dorsum of the head and the thorax with snowy white, making all the markings beneath being quite obscured. Female is more robust and exhibits several color morphs. The green color of the male is replaced by red in the females in the red forms. In androchrome forms, the female has same green colors as in the male.[7] Female colour variation is depended on ontogenic colour change associated with sexual development too.[8]
It breeds in marshes and ponds.[7][9][10][11][12]
The species name pygmaea is from the Greek word for pygmy. In 1842, Jules Pierre Rambur, writing in Latin, started his description of this damselfly: Minimum obscure viridi aenum - very small dark green copper.[2][13]
