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 Hangzhou on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 172 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.
August
In that month about 40% of wildlife watchers report a Pale Grass Blue in Hangzhou on a given day, against under 5% in December to March, the lowest months. That is one of Hangzhou's wettest months, with about 180 mm of rain against 65 mm in December.
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.
41st of 61
Of the 61 cities where we can rate Pale Grass Blue sightings, Hangzhou ranks 41st 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 Hangzhou (family Lycaenidae, Gossamer-winged Butterflies) are Pea Blue (about 10%), Plains Cupid (about 10%) and Short-Tailed Blue (about 10%), 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 Hangzhou (45 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.
