Zizina otis occurs in south Asia. It was reported from the Hawaiian island of Oahu in 2008. While Zizina otis labradus is found in the North Island of New Zealand and the northern part of the South Island, Zizina otis oxleyi is found only in the southern part of the South Island.
Pale violet blue, with a silvery sheen in certain lights, forewing: a broad brown edging along the termen, which covers in some specimens quite the outer fourth of the wing, while in others is much narrower. It is always broadest at the apex and is bounded by an anteciliary darker line, beyond which the cilia are brownish at base and white outwardly.
Hindwing: anterior or costal third to half and apex brown; a slender black anteciliary line, beyond which the cilia are as in the forewing. Brownish grey. Forewing: a short, transverse, dusky lunule on the discocellulars... Wikipedia →

With luck
About 10% of wildlife watchers report a Southern Blue sighting in Fiordland National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 201 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Southern Blue in Fiordland National Park on a given day, against under 5% in April to December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Southern Blue sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Fiordland National Park, in our data
Fiordland National Park is the only park on Wallace's Line with enough records to rate Southern Blue sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Southern Blue that you can see in Fiordland National Park (order Lepidoptera, Butterflies and Moths) are New Zealand Red Admiral (about 20%), Lacebark Looper (about 20%) and Forest Semilooper (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Blue is recorded against all the insects logged in Fiordland National Park (10 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
