摘要：

Observations on the ecology of Xenosaurus grandis near Cuautlapan, Veracruz revealed chat this rarely studied lizard is locally abundant in crevices of boulders in perennial tropical forest. Individuals are solitary and highly aggressive when placed together. A diurnally active thermal conformer, body temperatures (average = 22.7 degrees C) correlate with both substrate and air temperatures and basking was not observed. Upper thermal limits (CTM) averaged 37.4 degrees C. Food consisted primarily of insects by volume (Lepidoptera larvae and Orthoptera predominated), but occasional lizard prey are taken.
