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.

With luck
About 10% of wildlife watchers report a Pale Grass Blue sighting in Beijing on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to November
In those months about 10% of wildlife watchers report a Pale Grass Blue in Beijing on a given day, against under 5% in December to May, the lowest months. Those are among Beijing's wettest months, with about 75 mm of rain a month against almost none in January.
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.
61st of 61
Of the 61 cities where we can rate Pale Grass Blue sightings, Beijing ranks 61st at about 10%. 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 Beijing (family Lycaenidae, Gossamer-winged Butterflies) are Short-Tailed Blue (about 10%), Tongeia filicaudis (about 10%) and Common Flash (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 Beijing (42 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.
