These are called ‘Mopane worms’ although they are actually caterpillars. They are quite nutritious as they are rich in protein. I tried one at the Lesedi Village north of Johannesburg…it was crunchy, salty and tasted like a mouthful of seaweed. Other than that it didn’t have much flavour. I doubt they could replace popcorn or chips in terms of eating enjoyment but at least they’re good for you!
