With luck
About 10% of wildlife watchers report a Green Flash sighting in Hong Kong on a given day, based on 69 verified sightings from GBIF citizen-science data. It is the 175th most-seen of the 1125 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.
February to October
In those months about 10% of wildlife watchers report a Green Flash in Hong Kong on a given day, against under 5% in November to January, the lowest months.
Among the best
Of the 4 cities where we can rate Green Flash sightings, Hong Kong ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tuen Mun (China, about 10%).
Same family: Lycaenidae
The closest relatives of the Green Flash that you can see in Hong Kong (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Plains Cupid (about 20%) and Abisara echeria (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Flash is recorded against all the insects logged in Hong Kong (69 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.
