Abstract. -- Diet composition of the Mexican spadefoot toad has been poorly studied, especially in the southern part of this species' geographic range. This study reports the diet composition of a population inhabiting a sand dune system in southwestern Coahuila, Mexico.

Numerically, ants comprized the greater percentage of the stomach contents (49.7%) followed by homopterans (16.7%) and hemipterans (12.8%).
