Likely
About 40% of wildlife watchers report a Rough Mabuya sighting in Sepilok on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 34 reptiles we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.

In that month about 60% of wildlife watchers report a Rough Mabuya in Sepilok on a given day, against about 30% in May and November–December, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Rough Mabuya sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.

Of the 6 parks where we can rate Rough Mabuya sightings, Sepilok has the highest daily chance: about 40%. Next come Tanjung Puting National Park (Indonesia, about 30%) and Danum Valley Conservation Area (Malaysia, about 30%).
Same genus: Eutropis
The closest relatives of the Rough Mabuya that you can see in Sepilok (genus Eutropis, Asian Mabuyas) are Lewis's mabuya (about 20%) and Many-lined Sun-skink (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Rough Mabuya is recorded against all the reptiles logged in Sepilok (80 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.
