Ontogenetic color change in Ischnura kellicotti Williamson females (Zygoptera: Coenagrionidae)

I. kellicotti has been classified as a sp. with dichromatic females. By marking orange females it is demonstrated that they change color ontogenetically into the blue form. Orange and blue females were dissected and all blue forms contained mature eggs, but no orange females held eggs. Blue females averaged 28.3 mg, while orange individuals averaged 20.8 mg. It is concluded that there is no evidence that this sp. has dichromatic females.
