With luck
About 10% of wildlife watchers report a Green's Gem sighting in Sinharaja Forest Reserve on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 65th 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.
February and September
In those months about 30% of wildlife watchers report a Green's Gem in Sinharaja Forest Reserve on a given day, against under 5% in April–July and October–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Green's Gem sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Green's Gem sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Green's Gem is recorded against all the insects logged in Sinharaja Forest Reserve (7 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.
