Rare
Under 5% of wildlife watchers report a Two Lines sighting in Johannesburg on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 180th most-seen of the 213 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.
March–April, October and December
In those months about 10% of wildlife watchers report a Two Lines in Johannesburg on a given day, against under 5% in January–February, May–September and November, the lowest months. Those are among Johannesburg's wettest months, with about 75 mm of rain a month against almost none in July.
Only Johannesburg, in our data
Johannesburg is the only city on Wallace's Line with enough records to rate Two Lines sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Two Lines is recorded against all the insects logged in Johannesburg (5 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.
