Rare
Under 5% of wildlife watchers report an Orange Hairstreak sighting in Tokyo on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 342nd most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report an Orange Hairstreak in Tokyo on a given day, against under 5% in July to April, the lowest months.
3rd of 3
Of the 3 cities where we can rate Orange Hairstreak sightings, Tokyo ranks 3rd at under 5%. The best odds are in Seoul (South Korea, about 10%) and Osaka (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange Hairstreak is recorded against all the insects logged in Tokyo (32 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.
