With luck
About 10% of wildlife watchers report a Eurema regularis sighting in Durban on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 163rd 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 30%, if each day is a fresh chance.
April–August and October
In those months about 10% of wildlife watchers report a Eurema regularis in Durban on a given day, against under 5% in September and November–March, the lowest months. Those are among Durban's driest months, with about 65 mm of rain a month against 210 mm in January.
Among the best
Of the 2 cities where we can rate Eurema regularis sightings, Durban ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Lusaka (Zambia, about 10%).
Same genus: Eurema
The closest relatives of the Eurema regularis that you can see in Durban (genus Eurema, Grass Yellows) are Malagasy Grass Yellow (about 10%) and Broad-Bordered Grass Yellow (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurema regularis is recorded against all the insects logged in Durban (13 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.
