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.
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 →

Possible
About 20% of wildlife watchers report a Lesser Grass Blue sighting in Guwahati on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 77 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Lesser Grass Blue in Guwahati on a given day, against under 5% in January, March–April, June, September and November, the lowest months. That is one of Guwahati's driest months, with about 20 mm of rain against 370 mm in June.
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.
18th of 47
Of the 47 cities where we can rate Lesser Grass Blue sightings, Guwahati ranks 18th at about 20%. The best odds are in Davao City (Philippines, about 40%), Kota (India, about 40%) and Vadodara (India, about 30%).
Same family: Lycaenidae
The closest relatives of the Lesser Grass Blue that you can see in Guwahati (family Lycaenidae, Gossamer-winged Butterflies) are Red Pierrot (about 50%), Pale Grass Blue (about 30%) and Common Pierrot (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lesser Grass Blue is recorded against all the insects logged in Guwahati (8 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.
