Possible
About 20% of wildlife watchers report a Yellow Featherlegs sighting in Doi Inthanon National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 47th most-seen of the 153 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.
June
In that month about 30% of wildlife watchers report a Yellow Featherlegs in Doi Inthanon National Park on a given day, against under 5% in April and August–October, the lowest months. That is one of Doi Inthanon National Park's wettest months, with about 270 mm of rain against 20 mm in February.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Yellow Featherlegs sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 6
Of the 6 parks where we can rate Yellow Featherlegs sightings, Doi Inthanon National Park ranks 4th at about 20%. The best odds are in Khao Sok National Park (Thailand, about 30%), Khao Yai National Park (Thailand, about 20%) and Kaeng Krachan National Park (Thailand, about 20%).
Same family: Platycnemididae
The closest relatives of the Yellow Featherlegs that you can see in Doi Inthanon National Park (family Platycnemididae, White-legged damselflies) are Coeliccia loogali (about 20%), Coeliccia chromothorax (about 20%) and Calicnemia erythromelas (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow Featherlegs is recorded against all the insects logged in Doi Inthanon National Park (17 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.
