Zizula hylax, the tiny grass blue, is a species of blue butterfly. Male upperside: dull violet blue, which changes to a brighter tint of violet in certain lights. Forewing: the costa very narrowly, the termen much more broadly dull brown; this edging to the termen in most specimens decreases in width from apex to tornus, and is outwardly followed by an anteciliary darker brown line. Cilia brownish anteriorly, posteriorly brownish at the base with the apical portions white. Hindwing: the ground colour brighter than on the forewing, the costal and terminal margins much more narrowly edged with brown, which edging is merged in the anteciliary dark brown line. Cilia: brown along their basal halves, white apically.
Underside: grey. Forewing: a dusky brown lunular line on the discocellulars; two subcostal spots above the cell, one on either side of the discocellular lunule; a very strongly curved discal series of five spots, of which the posterior three are somewhat lunular in shape and placed obliquely en echelon, the next above these hook shaped, the anterior spot round; both the subcostal spots and the spots of the discal series are black, each narrowly encircled with...

With luck
About 10% of wildlife watchers report a Tiny Grass Blue sighting in Bengaluru on a given day, based on 93 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
May and December–February
In those months about 20% of wildlife watchers report a Tiny Grass Blue in Bengaluru on a given day, against about 10% in March–April and June–November, the lowest months. Those are among Bengaluru's driest months, with about 35 mm of rain a month against 150 mm in September.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Tiny 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.
31st of 45
Of the 45 cities where we can rate Tiny Grass Blue sightings, Bengaluru ranks 31st at about 10%. The best odds are in Salem (India, about 40%), Madurai (India, about 40%) and Vadodara (India, about 40%).
Same family: Lycaenidae
The closest relatives of the Tiny Grass Blue that you can see in Bengaluru (family Lycaenidae, Gossamer-winged Butterflies) are Red Pierrot (about 30%), Plains Cupid (about 30%) and Common Cerulean (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tiny Grass Blue is recorded against all the insects logged in Bengaluru (93 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.
