Rare
Under 5% of wildlife watchers report an Achaea serva sighting in Singapore on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 372nd most-seen of the 1045 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.
February and July
In those months about 10% of wildlife watchers report an Achaea serva in Singapore on a given day, against under 5% in March–June and August–January, the lowest months.
4th of 6
Of the 6 cities where we can rate Achaea serva sightings, Singapore ranks 4th at under 5%. The best odds are in Chennai (India, about 10%), Kochi (India, about 10%) and Tuen Mun (China, under 5%).
GBIF citizen-science records
It is estimated from how often the Achaea serva is recorded against all the insects logged in Singapore (50 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.
