Rare
Under 5% of wildlife watchers report a Common Duffer sighting in Guangzhou on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 252nd most-seen of the 482 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.
June–July and September
In those months about 10% of wildlife watchers report a Common Duffer in Guangzhou on a given day, against under 5% in August and October–May, the lowest months. Those are among Guangzhou's wettest months, with about 230 mm of rain a month against 30 mm in December.
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.
5th of 6
Of the 6 cities where we can rate Common Duffer sightings, Guangzhou ranks 5th 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 Guangzhou (family Nymphalidae, Brush-footed Butterflies) are Lemon Pansy (about 20%), Chocolate Pansy (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 Guangzhou (11 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.
