With luck
About 10% of wildlife watchers report a Common Duffer sighting in Taipei on a given day, based on 205 verified sightings from GBIF citizen-science data. It is the 50th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
June–August and October–November
In those months about 20% of wildlife watchers report a Common Duffer in Taipei on a given day, against about 10% in September and December–May, 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.
Yes
Of the 6 cities where we can rate Common Duffer sightings, Taipei has the highest daily chance: about 10%. Next come 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 Taipei (family Nymphalidae, Brush-footed Butterflies) are Common Mapwing (about 20%), Common Palmfly (about 20%) and Great Eggfly (about 20%), 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 Taipei (205 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.
