About Ischnura posita
Ischnura posita, the fragile forktail, was first recorded in Hawaiʻi in a Punahou lily pond in 1936.
Natural history and identification
Ischnura posita, the fragile forktail, was first recorded in Hawaiʻi in a Punahou lily pond in 1936. It subsequently became widespread in Hawaiian wetlands and stream habitats, including Kauaʻi. It is an introduced damselfly, distinct from the endemic Megalagrion radiation. The historical first record provides an introduction timeline, while the separate flying adult and aquatic immature stages matter when interpreting whether a site supports breeding.
