There have been no comprehensive studies of this lizard's biology and very little is therefore known about its life history and behaviour (3).
The Saint Croix ground lizard is known to be a ‘heliothermic temperature regulator', meaning that it is active during the warmest, middle portion of the day. During the night and on cooler, cloudy days the lizard tends to stay within its burrow under rocks or underground. An opportunistic hunter, this lizard actively prowls, roots and digs for virtually any prey items it can find, including amphipods (small, shrimp-like crustaceans), moths, ants, small hermit crabs, and the eggs and hatchlings of anoles (4).
