Possible
About 20% of wildlife watchers report a Pale Grass Blue sighting in Nikko National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 86 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August and October–November
In those months about 30% of wildlife watchers report a Pale Grass Blue in Nikko National Park on a given day, against under 5% in February–July, September and December, the lowest months.
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.
Among the best
Of the 3 parks where we can rate Pale Grass Blue sightings, Nikko National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Manas National Park (India, about 20%).
Same family: Lycaenidae
The closest relatives of the Pale Grass Blue that you can see in Nikko National Park (family Lycaenidae, Gossamer-winged Butterflies) are Pea Blue (about 20%) and Silver-Studded Blue (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 Nikko National Park (5 verified sightings from 2019 to 2026), 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.
