We studied the autecology of the gecko Hentidactylus agrius at the Serido Ecological Station (ESEC Serido), a protected area of the Brazilian Caatinga, northeastern Brazil. Monthly, we inspected a sampling area composed of live transects of 200 m from August 2012 to August 2013. We recorded active lizards only during the night, predominantly in areas with rocky outcrops, where lizards used all available microhahitats equitably. Adult females (n = 25) were significantly larger than adult males (n = 18) in body size, but males had relatively longer and wider heads than females. The diet was composed mainly by insect larvae, termites, and spiders, and showed variations between dry and wet times, both qualitatively and quantitatively. We found no intersexual differences in diet, but ontogenetic differences were evident, chiefly in prey size. The body size of lizards was positively associated with maximum prey size, but not with minimum prey size. Rainfall seasonality did not play a determining role in habitat/microhabitat use and lizard abundance but influenced diet composition.
