- Identification Key:
- Abdomen palest blue, with the black dorsal markings very restricted. Abdominal segments 4 to 6 with black apical rings confluent with a subapical spot shaped like an arrow-head; segment 7 with a dorsal stripe on its basal three-fourths.
- Distinguishing Feature:
- The species frequents grassy marsh-lands, in which it breeds. Very conspicuous on the wing in spite of its small size, owing to its pearly blue colouring. Closely allied to A. lacteola, from which it differs principally by abdominal segments 4 to 10 also bearing black markings, these segments being immaculate in the former.

- Description:
- Agriocnemis pieris, one of the smallest damselflies of Bangladesh, is a closely similar species of Agriocnemis lecteola and often overlooked.
- Male Description:
- The males are white and pale blue in color. Length of the abdomen and hind wings are 16-18 mm and 11-12 mm respectively. The head is green and black capped, legs are white with black spine. The prothorax is black, anterior of the prothorax is green. Thorax is dorsally black, laterally pale blue with green antehumeral stripe. Abdominal segments and anal appendages are white. Segments 1 and 2 contain similar black scratches dorsally, segments 3-6 contain black dot and segment 7 with distinct black scratch, by which the species can be distinguished easily from Agriocnemis lecteola.
- Female Description:
- The females are often seen associated with males, green and black stripped slander damselfly. Very much confusing with A. lecteola female.
