Possible
About 20% of wildlife watchers report a Metallic Cerulean sighting in Sinharaja Forest Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 117 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.
March and November
In those months about 30% of wildlife watchers report a Metallic Cerulean in Sinharaja Forest Reserve on a given day, against under 5% in February, April–July and September–October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Metallic Cerulean sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Metallic Cerulean sightings, Sinharaja Forest Reserve has the highest daily chance: about 20%. Next come Doi Inthanon National Park (Thailand, about 10%) and Taroko National Park (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Metallic Cerulean is recorded against all the insects logged in Sinharaja Forest Reserve (9 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.
