Rare
Under 5% of wildlife watchers report a Common Duffer sighting in Singapore on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 548th 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 20%, if each day is a fresh chance.
January and June
In those months about 10% of wildlife watchers report a Common Duffer in Singapore on a given day, against under 5% in February–May and July–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Common Duffer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 cities where we can rate Common Duffer sightings, Singapore ranks 6th at under 5%. The best odds are in Taipei (Taiwan, about 10%), Tuen Mun (China, about 10%) and Hong Kong (China, about 10%).
Same family: Nymphalidae
The closest relatives of the Common Duffer that you can see in Singapore (family Nymphalidae, Brush-footed Butterflies) are Brown Pansy (about 40%), Plain Tiger Butterfly (about 30%) and Tawny Coster (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Duffer is recorded against all the insects logged in Singapore (20 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.
