Rare
Under 5% of wildlife watchers report a Black-Based Hummingbird Hawkmoth sighting in Taipei on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 396th 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 20%, if each day is a fresh chance.
March and October
In those months about 10% of wildlife watchers report a Black-Based Hummingbird Hawkmoth in Taipei on a given day, against under 5% in April–September and November–February, the lowest months.
2nd of 3
Of the 3 cities where we can rate Black-Based Hummingbird Hawkmoth sightings, Taipei ranks 2nd at under 5%. The best odds are in Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-Based Hummingbird Hawkmoth is recorded against all the insects logged in Taipei (18 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.
