Zizina otis, the lesser grass blue, is a species of blue (Lycaenidae) butterfly found in south and southeast Asia. The species was first described by Johan Christian Fabricius in 1787. The lesser grass blue is often misidentified as Zizina labradus, the common grass blue.
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.

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 Lesser Grass Blue sighting in Grampians National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 148 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Lesser Grass Blue in Grampians National Park on a given day, against under 5% in February and June–October, the lowest months. That is one of Grampians National Park's driest months, with about 35 mm of rain against 85 mm in October.
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.
10th of 18
Of the 18 parks where we can rate Lesser Grass Blue sightings, Grampians National Park ranks 10th at about 10%. The best odds are in Kosciuszko National Park (Australia, about 30%), Udawalawe National Park (Sri Lanka, about 30%) and Lamington National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Lesser Grass Blue is recorded against all the insects logged in Grampians National Park (12 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.
