The witchetty grub (also spelled witchety grub) is a term used in Australia for the large, white, wood-eating larvae of several moths. Particularly it applies to the larva of the cossid moth Endoxyla leucomochla, which feeds on the roots of the Witchetty bush (named for the grubs) that is found in central Australia. The grub is the most important insect food of the desert and was a staple in the diets of Aboriginal women and children.
The different larvae are said to taste similar, probably because they have similar wood-eating habits. Edible either raw or lightly cooked in hot ashes, they are sought out as a high-protein food by Indigenous Australians. The raw witchetty grub tastes like almonds and when cooked the skin becomes crisp like roast chicken while the inside becomes light yellow, like a fried egg.
