With luck
About 10% of wildlife watchers report an Orange-Tailed Marsh Dart sighting in Thiruvananthapuram on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 95th most-seen of the 112 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
March and April
In those months about 30% of wildlife watchers report an Orange-Tailed Marsh Dart in Thiruvananthapuram on a given day, against under 5% in May–August and November–February, the lowest months.

Across all the parks we cover, that three-hour window holds the most Orange-Tailed Marsh Dart sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Orange-Tailed Marsh Dart is recorded against all the insects logged in Thiruvananthapuram (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.
