Orthetrum pruinosum, the crimson-tailed marsh hawk, is a species of dragonfly in the family Libellulidae. It is a widespread species occurring from west India to Japan and south to Java and the Sunda Islands. A molecular phylogenetics study of Orthetrum dragonflies revealed that Orthetrum pruinosum is a cryptic species.
Young males have red abdomen as in Orthetrum chrysis. Females of both species look similar. It breeds in ponds, lakes and sluggish streams. List of odonates of Sri Lanka List of odonates of India List of odonata of Kerala Wikipedia →

Possible
About 20% of wildlife watchers report a Crimson-Tailed Marsh Hawk sighting in Kanha National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 50th most-seen of the 106 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Crimson-Tailed Marsh Hawk in Kanha National Park on a given day, against under 5% in February–March, May–June and September–November, the lowest months. That is one of Kanha National Park's driest months, with about 15 mm of rain against 430 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Crimson-Tailed Marsh Hawk sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 12
Of the 12 parks where we can rate Crimson-Tailed Marsh Hawk sightings, Kanha National Park ranks 8th at about 20%. The best odds are in Mudumalai National Park (India, about 30%), Periyar National Park (India, about 30%) and Cuc Phuong National Park (Vietnam, about 30%).
GBIF citizen-science records
It is estimated from how often the Crimson-Tailed Marsh Hawk is recorded against all the insects logged in Kanha National Park (8 verified sightings from 2019 to 2026), 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.
