What are 'witchedy grubs'?

Witchetty grubs are the larvae of several species of moths, particularly those in the family Cossidae, and are a traditional food source for Indigenous Australians. These grubs are typically found in the roots of certain trees, especially the witchetty bush, and are known for their high protein content and nutty flavor. They can be eaten raw or cooked, often roasted over a fire. Witchetty grubs are considered a valuable part of the bush tucker diet.
