With luck
About 10% of wildlife watchers report a Common Ciliate Blue sighting in Khao Yai National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 115th most-seen of the 221 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May–June and August–September
In those months about 20% of wildlife watchers report a Common Ciliate Blue in Khao Yai National Park on a given day, against under 5% in April, July, October and December–January, the lowest months. Those are among Khao Yai National Park's wettest months, with about 240 mm of rain a month against 15 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Ciliate Blue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Common Ciliate Blue sightings, Khao Yai National Park ranks 4th at about 10%. The best odds are in Cuc Phuong National Park (Vietnam, about 30%), Taman Negara National Park (Malaysia, about 20%) and Kaeng Krachan National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Ciliate Blue is recorded against all the insects logged in Khao Yai National Park (11 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.
