Sphaerodactylus glaucus is a species of gecko known by the common name collared dwarf gecko or least gecko. (geco-enano collarejo in Spanish). It is native to Mexico and parts of Central America, its range extending from Oaxaca and Veracruz in Mexico through Guatemala to Honduras.
This gecko has a cream-colored band bordered by two black bands around the neck. There is a similar band bordered by black spots at the base of the tail and another at the middle of the tail. It can be distinguished from S. continentalis by its dorsal scales, which are smooth rather than keeled. It is diurnal.
This species has been observed in several kinds of tropical forest, subtropical moist forest, and mangrove ecotones from sea level to 1000 meters in elevation. It is sometimes found near human habitation hiding under debris and in thatching.
This gecko is common in its range and faces no immediate major threats. It is sometimes prey and competition for the common house gecko (Hemidactylus frenatus) in human habitations, but not in wild habitat. Wikipedia →

With luck
About 10% of wildlife watchers report a Least Gecko sighting in Sian Ka'an Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 23 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Least Gecko in Sian Ka'an Biosphere Reserve on a given day, against under 5% in December to July, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Least Gecko sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Least Gecko sightings, Sian Ka'an Biosphere Reserve ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Calakmul Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Least Gecko is recorded against all the reptiles logged in Sian Ka'an Biosphere Reserve (5 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.
