Draco sumatranus, the common gliding lizard, is a species of agamid lizard endemic to Southeast Asia. It has elongated ribs and skin flaps on the sides of its body. When opened, these skin flaps allow it to glide between tree trunks.
It is primarily a tree dweller, except that the females come down to the forest floor to lay eggs. The body length is of about 9 cm (3.5 in), with a slightly longer tail. The body is of a dark grey/brown colouration with stripes and patterns to help it camouflage against the tree trunks. The males have a yellow triangular flap of skin under the chin, the gular fold, which is used to communicate with other lizards, mostly for mating. Females have a much smaller and blue flap.
They feed on small insects. Usually ants and termites. They are relatively common in forests and in urban settings such as parks and gardens. They are found in Southeast Asia: Indonesia, Malaysia, Singapore, and Palawan.
It was formerly considered a sub-species of Draco volans. Baker, Nick; Lim, Kelvin. 2008. Wild Animals of Singapore: A Photographic... Wikipedia →

Possible
About 20% of wildlife watchers report a Sumatran Gliding Lizard sighting in Gunung Leuser National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 47 reptiles 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.
November
In that month about 40% of wildlife watchers report a Sumatran Gliding Lizard in Gunung Leuser National Park on a given day, against under 5% in February, June, August–September and December, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Sumatran Gliding Lizard sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Gunung Leuser National Park, in our data
Gunung Leuser National Park is the only park on Wallace's Line with enough records to rate Sumatran Gliding Lizard sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sumatran Gliding Lizard is recorded against all the reptiles logged in Gunung Leuser 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.
