The size of the prey depends on mostly the size of the crocodile. Young hatchlings generally feed on smaller prey, preferring small fish, frogs, insects and small aquatic invertebrates before taking on larger fish, amphibians and small reptiles.
Reptiles and Amphibians. Predatory reptiles and amphibians don't seem to care that a wasp is capable of stinging. They simply see another meal on the long list of insects they're willing to eat. Frogs, lizards, toads, salamanders and sometimes even turtles will make a meal out of a wasp. These predators don't seek out wasps as their main source of food, but rather are opportunistic and will eat one if given the chance.
