[2] Additionally, the big-scaled dwarf gecko displays sexual dimorphism with males being larger than females.

The big-scaled dwarf gecko is commonly seen on the forest floor of the islands, in their preferred microhabitat of leaf litter.

[4] Another notable characteristic of the big-scaled dwarf gecko is their preference for cooler environments due to their miniature size which increases their rate of desiccation.

Their total evaporative water loss grows with temperature and so these lizards’ behaviors and location alters during the day in order to seek out appropriate microhabitats.

[7] These two microhabitats do dictate certain characteristics of the lizard, with those from the coastal region being more visual attuned to higher light levels than those from the forest floor.

As such, the big-scaled dwarf gecko displays sexual dimorphism, meaning male and female counterparts exist with obvious physical differences.

[11] In terms of appearance, the big-scaled dwarf gecko has its notable imbricate dorsal scales, which overlap over each other.

Females, though, have distinct markings that males lack such as the canthal line that starts at their snout and ends at their neck.

[10] The big-scaled dwarf gecko, Sphaerodactylus macrolepis was first discovered in 1859 on St. Croix, a part of the US Virgin Islands.

This separation occurred due to their slightly different scale types and coloration and was not based purely on location.

[4] While predation on the islands that the big-scaled dwarf gecko occupies is not extremely high, they are still hunted by other organisms such as the Anolis pelchullus, more commonly known as the Puerto Rican grass bush anole.

Additionally, it has been documented that the big-scaled dwarf gecko in the Virgin Islands region  are also hunted by birds such as the bridled quail dove (Geotrygon mystacea).

The snake reacts with caudal luring, a type of wriggling movement when approaching prey, in the presence of S. macrolepis.

[16] Due to an overlap of habitats, namely the forest floor, Solenopsis invicta, or the red imported fire ants, can come in contact with the big-scaled dwarf gecko.

It was noted that when the big-scaled dwarf gecko was not near any fire ants, it displayed little to no body twitching and would remain relatively immobile.

In the case that contact was unavoidable, the big-scaled dwarf gecko would use an array of weaponized body movements such as limb and tail flicks.

During the late night and early morning, the big-scaled dwarf geckos can experience its preferred temperature in all microhabitats.

As mentioned in the thermoregulation section, the big-scaled dwarf gecko easily experiences desiccation due to its small size.

As such, S. macrolepis from the two areas show separate levels of motion detection ability at different light ranges.

These ranges do not change between sexes, with both male and female S. macrolepis displaying optimal visual and motion acuity at the same light levels only differing depending on habitat.
