Xanthocnemis zealandica
Xanthocnemis zealandica, commonly known as common redcoat damselfly, red damselfly, or red coat damselfly, is the most common native New Zealand damselfly. Adult damselflies are often seen flying around vegetation close to streams. X. zealandica has a 2–3 year life cycle; the shorter one was observed near sea level while the longer one was characteristic to a mid-elevation site ( above sea level). Some individuals at the lowland site may even complete their life cycle in one year. X. zealandica larvae are widespread across New Zealand, occurring in rocky and weedy streams and ponds. It is predominantly a low-altitude species but can reach  above sea level. The larvae of the red damselfly are identified by their pointed tail gills and long hairs by the tip. References
