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.

Possible
About 20% of wildlife watchers report a Lesser Grass Blue sighting in Melbourne on a given day, based on 751 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 875 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January to March
In those months about 30% of wildlife watchers report a Lesser Grass Blue in Melbourne on a given day, against under 5% in June to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lesser Grass Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
20th of 47
Of the 47 cities where we can rate Lesser Grass Blue sightings, Melbourne ranks 20th at about 20%. The best odds are in Davao City (Philippines, about 40%), Kota (India, about 40%) and Vadodara (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Lesser Grass Blue is recorded against all the insects logged in Melbourne (751 verified sightings), 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.
