With luck
About 10% of wildlife watchers report a Red-Clover Blue sighting in Nairobi on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 123 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.
July
In that month about 20% of wildlife watchers report a Red-Clover Blue in Nairobi on a given day, against under 5% in January–March, June and August–November, the lowest months. That is one of Nairobi's driest months, with about 25 mm of rain against 150 mm in April.
Only Nairobi, in our data
Nairobi is the only city on Wallace's Line with enough records to rate Red-Clover Blue sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Red-Clover Blue is recorded against all the insects logged in Nairobi (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.
