Gekko horsfieldii, also known commonly as Horsfield's flying gecko, Horsfield's gliding gecko, and Horsfield's parachute gecko, is a species of lizard in the family Gekkonidae. The species is endemic to Asia. The specific name, horsfieldii, is in honor of American naturalist Thomas Horsfield.
G. horsfieldii is found in Brunei, Indonesia, Malaysia, Myanmar, Sarawak, Singapore, Sumatra, and Thailand. The preferred natural habitat of G. horsfieldii is forest, at altitudes from sea level to 300 m (980 ft). G. horsfieldii may attain a snout-to-vent length (SVL) of 8 cm (3.1 in).
G. horsfieldii preys upon small insects. G. horsfieldii is oviparous. The adult female lays a clutch of two eggs. Each egg measures 13.7 by 11.9 mm (0.54 by 0.47 in). Gray JE (1827).

With luck
About 10% of wildlife watchers report a Horsfield's Flying Gecko sighting in Sepilok on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 34 reptiles 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.
November to February
In those months about 20% of wildlife watchers report a Horsfield's Flying Gecko in Sepilok on a given day, against under 5% in March–April, June–August and October, the lowest months.

Across all the parks we cover, that three-hour window holds the most Horsfield's Flying Gecko sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Horsfield's Flying Gecko sightings, Sepilok ranks 2nd at about 10%. The best odds are in Danum Valley Conservation Area (Malaysia, about 20%).

GBIF citizen-science records
It is estimated from how often the Horsfield's Flying Gecko is recorded against all the reptiles logged in Sepilok (6 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.
