The bronze grass skink, bronze mabuya or speckled forest skink (Eutropis macularia), is a species of skink found in South and Southeast Asia. It is a common, but shy, ground-dwelling species that is active both day and night.
The bronze grass skink has a cylindrical body, dorsal scales with 5–8 keels, and smooth ventral scales. A pair of dorso-lateral bands start from above the eye and extend to the base of the tail. As with other Eutropis species, the scales are keeled. The snout is short, obtusely keeled and acuminate, and the lower eyelid is scaly. The nostril is located behind the vertical suture between the rostral scale and the first labial scale. The ear-opening is oval, about the same size as a lateral scale, or a little smaller. The dorsal, nuchal, and lateral scales have five to seven sharp keels, and there are 26 to 30 scales, approximately equal in size, round the middle of the body. The adpressed limbs meet or overlap. The digits are short and the lamellae between them smooth. The tail is 1.25 to 1.75 times the length of the head and body. Brown or olive-brown above, sides darker and usually with white black-edged spots; back uniform, or black-spotted... Wikipedia →

Possible
About 20% of wildlife watchers report a Bronze Grass Skink sighting in Kaeng Krachan National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 56 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.
September
In that month about 40% of wildlife watchers report a Bronze Grass Skink in Kaeng Krachan National Park on a given day, against about 10% in January–March, May and July, the lowest months. That is one of Kaeng Krachan National Park's wettest months, with about 260 mm of rain against 30 mm in December.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Bronze Grass Skink 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 Bronze Grass Skink sightings, Kaeng Krachan National Park ranks 2nd at about 20%. The best odds are in Cat Tien National Park (Vietnam, about 40%).
GBIF citizen-science records
It is estimated from how often the Bronze Grass Skink is recorded against all the reptiles logged in Kaeng Krachan National Park (29 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.
