Are Greater Wax moth larvae (Galleria mellonella) nutritionally apt for Xenopus Laevis?

The alleged reason was that crickets legs/bodies are too hard for xenopus. I don't buy that, xenopus are effective predators and scavengers and will eat anything that falls in the water. I am sure they eat water beetles in the wild which have tougher bodies than a cricket.
