Phyllorhynchus have been proposed to eat a wide variety of food items. The leading hypothesis is that the tails of the gecko Coleonyx variegatus are an important food source. We dissected museum specimens of P. decurtatus and P. browni. The diet of P. decurtatus consisted primarily of squamate eggs; few individuals of that species contained the tails of C. variegatus. The diet of P. browni consisted entirely of squamate eggs. We compared the monthly diet patterns between the sexes, as well as between the species.
