In 3 days ~50% in a week ~80%
Pseudozizeeria maha, the pale grass blue, is a small butterfly found in South Asia that belongs to the lycaenids or blues family. The species was first described by Vincenz Kollar in 1844. The subspecies of Pseudozizeeria maha are-
Pseudozizeeria maha saishutonis (Matsumura, 1927) – Korea Pseudozizeeria maha argia (Ménétriès, 1857) – Japan Male. Upperside silvery light blue with a satiny sheen in certain lights. Forewing: the apical half of the costa narrowly and the terminal margin for varying widths fuscous black, bounded outwardly on the latter by an obscure anteciliary black line. Hindwing: the costa broadly, the termen somewhat more narrowly fuscous black as in the forewing, with the width of this dark edging similarly variable; in addition there is a very diffuse and ill-defined subterminal series of spots darker than the fuscous margin.

Possible
About 20% of wildlife watchers report a Pale Grass Blue sighting in Kathmandu on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 71 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.
July and December
In those months about 40% of wildlife watchers report a Pale Grass Blue in Kathmandu on a given day, against under 5% in January–February and May, the lowest months. Those are among Kathmandu's wettest months, with about 140 mm of rain a month against almost none in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pale 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.
27th of 61
Of the 61 cities where we can rate Pale Grass Blue sightings, Kathmandu ranks 27th at about 20%. The best odds are in Gwangju (South Korea, about 60%), Jamshedpur (India, about 50%) and Kanpur (India, about 40%).
Same family: Lycaenidae
The closest relatives of the Pale Grass Blue that you can see in Kathmandu (family Lycaenidae, Gossamer-winged Butterflies) are Metallic Cerulean (about 20%), Pea Blue (about 20%) and Plains Cupid (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pale Grass Blue is recorded against all the insects logged in Kathmandu (19 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.
