Platycnemis acutipennis, known as the orange featherleg or the orange white-legged damselfly, is a species of damselfly in the family Platycnemididae.

[1][2][3] Platycnemis acutipennis is the only European damselfly which combines an orange-red abdomen and blue eyes.

[4] The male has moderately wide hind tibias (wider in both P. pennipes and P. latipes; and the males of both those species have blue abdomens).

Platycnemis acutipennis lives in fresh water, either still or up to moderately fast-flowing.

[5] Platycnemis acutipennis is common and widely distributed across the southwest of Europe including Portugal, Spain, and France; it is endemic to that area.
