Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA ARTHROPODA INSECTA ODONATA COENAGRIONIDAE

Scientific Name: Xanthocnemis zealandica
Species Authority: (McLachlan, 1873)
Common Name(s):
English Common Redcoat Damselfly
Synonym(s):
Telebasis zealandica McLachlan, 1873
Taxonomic Notes: Massive habitat modification throughout New Zealand (particularly the North Island) since c.1820 has created new selection pressures on this genus, that has affected distribution, morphology and genetics, possibly leading to positive hybridisation. This species has suspiciously variable morphology, and its taxonomy needs to be studied in greater detail (R. Rowe pers. comm. 2011). Despite the recent recognition of several species, it is probable that several more or less isolated taxonomic groups remain 'undiscovered' in this species (Rowe 1987).

Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species operates in a wide variety of habitats predominantly at lower altitudes, including streams, backwater, ponds, lake margins, pools on the side of braided rivers. It is very common in soft bottom sites, and is reasonably pollution and salinity tolerant. Terrestrial habitats consist generally of grasslands surrounding breeding habitats (Rowe 1987). Populations are normally localized around breeding sites. Adults regularly occur more than 500 m from breeding habitat but do not disperse widely (Rowe 1987). Larval lifespan is 1-3 years, dependant on temperature (Deacon 1978). Age to maturity is usually ten days and then breeding occurs every 3-4 days. Adults live to about 30 days (R. Rowe pers. comm. 2011).
Systems: Terrestrial; Freshwater
