With luck
About 10% of wildlife watchers report an Ornate Hydriris Moth sighting in Nairobi on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 28th most-seen of the 123 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February
In that month about 30% of wildlife watchers report an Ornate Hydriris Moth in Nairobi on a given day, against under 5% in March–April and October–January, the lowest months. That is one of Nairobi's driest months, with about 30 mm of rain against 150 mm in April.

GBIF citizen-science records
It is estimated from how often the Ornate Hydriris Moth is recorded against all the insects logged in Nairobi (14 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.
