Possible
About 30% of wildlife watchers report a Western Golden Dartlet sighting in Kota on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 33 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
November
In that month about 60% of wildlife watchers report a Western Golden Dartlet in Kota on a given day, against under 5% in March and July–August, the lowest months. That is one of Kota's driest months, with about 5 mm of rain against 260 mm in August.
2nd of 16
Of the 16 cities where we can rate Western Golden Dartlet sightings, Kota ranks 2nd at about 30%. The best odds are in Tiruchirappalli (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Western Golden Dartlet is recorded against all the insects logged in Kota (18 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.
