With luck
About 10% of wildlife watchers report a False Dotted Border sighting in Durban on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 80th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April to February
In those months about 10% of wildlife watchers report a False Dotted Border in Durban on a given day, against under 5% in March, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most False Dotted Border sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Durban, in our data
Durban is the only city on Wallace's Line with enough records to rate False Dotted Border sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Belenois
The closest relatives of the False Dotted Border that you can see in Durban (genus Belenois) are African Caper (about 20%) and Pioneer White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the False Dotted Border is recorded against all the insects logged in Durban (29 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.
