We quantified the food habits of the endangered blunt-nosed leopard lizard (Gambelia sila), an endemic species of the San Joaquin Valley, California. Based on analyses of stomach contents and prey remains in scats, we determined that this species is an opportunistic predator that eats large numbers of orthopterans, coleopterans, and hymenopterans, with dipterans, hemipterans, and lizards taken in lesser numbers. These data are similar to the qualitative or unpublished data of previous studies, and also are similar to the food habits of the congeneric Gambelia wislizenii.
