With luck
About 10% of wildlife watchers report a Dancing Dropwing sighting in Bengaluru on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 243rd most-seen of the 477 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.
April–May, August–September and November
In those months about 10% of wildlife watchers report a Dancing Dropwing in Bengaluru on a given day, against under 5% in June–July, October and December–March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dancing Dropwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate Dancing Dropwing sightings, Bengaluru ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Kolkata (India, about 10%), Salem (India, about 10%) and Chennai (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Dancing Dropwing is recorded against all the insects logged in Bengaluru (15 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.
