Ischnura is a genus of damselflies known as forktails or bluetails in the family Coenagrionidae.[2] The genus is distributed worldwide, including various oceanic islands. The males have a forked projection and blue segments at the tip of the abdomen which give the group their common names.[3]

Characteristics

[edit]

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.[3]

Etymology

[edit]

The genus name Ischnura is derived from the Greek ἰσχνός (ischnos, "thin" or "slender") and οὐρά (oura, "tail"), referring to the slender abdomen of species in the genus.[1][4]

Species

[edit]
Ischnura ramburii feeding on Ischnura posita

The genus Ischnura includes the following species:[5][6]
