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.

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 →

GBIF citizen-science records
It is estimated from how often the Lesser Grass Blue is recorded against all the insects logged in Daintree National Park (15 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.
