Ischnura

Ischnura is a genus of damselflies known as forktails (or sometimes bluetails) in the family Coenagrionidae. Forktails are distributed worldwide, including various oceanic islands. The males have a forked projection at the tip of the abdomen which gives the group their common name.

Characteristics
Forktails are small or very small damselflies. The compound eyes of mature individuals have a dark upper region and contrasting lower part. The thorax is often green and may have lateral stripes and the abdomen in males is black with a blue tip. Females of some species are polymorphic, some being orangish and darkening with age, while others resemble the male.
