Rare
Under 5% of wildlife watchers report a Green Flash sighting in Taipei on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 314th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to October
In those months about 10% of wildlife watchers report a Green Flash in Taipei on a given day, against under 5% in November to May, the lowest months.
3rd of 4
Of the 4 cities where we can rate Green Flash sightings, Taipei ranks 3rd at under 5%. The best odds are in Tuen Mun (China, about 10%) and Hong Kong (China, about 10%).
Same family: Lycaenidae
The closest relatives of the Green Flash that you can see in Taipei (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Metallic Cerulean (about 20%) and Dark Cerulean (about 10%), 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 Taipei (30 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.
