Agriocnemis femina

Species Name: Agriocnemis femina
Family: Coenagrionidae

Look in the grass beside drains and ponds in open areas near your house or in the paddy fields and you will almost surely find this species of damselfly. You have to look closely as they are really small and because their colour changes with age and the sexes are different in colour, they are a bit confusing and difficult to identify properly. Furthermore many small damselflies look very similar so it’s really hard for us non-experts to confirm the species.

Young males are green and black in colour with the tip of the abdomen (“tail”) orange, but as they grow older they become darker and the thorax becomes covered with a white growth called pruinescence and the orange at tip of its abdomen fades. So with naked eye they look little white bodied insects with dark “tails”.

Immature females on the other hand are bright red which turn olive greenish with dark brown markings.

I used to think they were four different species!
