Possible
About 30% of wildlife watchers report a Redtail Marquis sighting in Cat Tien National Park on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 125 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Redtail Marquis in Cat Tien National Park on a given day, against under 5% in January and September–October, the lowest months. That is one of Cat Tien National Park's driest months, with about 30 mm of rain against 490 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Redtail Marquis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Redtail Marquis sightings, Cat Tien National Park has the highest daily chance: about 30%. Next come Kaeng Krachan National Park (Thailand, about 20%).
GBIF citizen-science records
It is estimated from how often the Redtail Marquis is recorded against all the insects logged in Cat Tien National Park (37 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.
