Possible
About 20% of wildlife watchers report an Orange-Tailed Marsh Dart sighting in Johor Bahru on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 27th most-seen of the 53 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.
December
In that month about 40% of wildlife watchers report an Orange-Tailed Marsh Dart in Johor Bahru on a given day, against under 5% in January–May and August–September, the lowest months. That is one of Johor Bahru's wettest months, with about 300 mm of rain against 100 mm in February.
Between 8 and 11 am
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.
10th of 15
Of the 15 cities where we can rate Orange-Tailed Marsh Dart sightings, Johor Bahru ranks 10th at about 20%. The best odds are in Thrissur (India, about 30%), Kolkata (India, about 30%) and Kuching (Malaysia, about 30%).
GBIF citizen-science records
It is estimated from how often the Orange-Tailed Marsh Dart is recorded against all the insects logged in Johor Bahru (7 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.
