Abstract

Stomach analyses of 86 Sceloporus undulatus tristichus from central Arizona indicate Isoptera are major food items, both numerically and volumetrically in late July and August. Predation on the southwestern pine tip moth, Rhyacionia neomexicana, is apparently insignificant. Four families of insects and ten families of spiders are reported as prey of Sceloporus for the first time.
