The Aboriginal art symbol for a witchetty grub is a simplified illustration of the larva, usually emphasizing the sections of its body and head.
Witchetty grubs are often depicted in Aboriginal paintings that document the sites where they can be found. This kind of traditional knowledge is important for survival in the bush.
Witchetty grubs are large white moth larvae that may grow up to 20 centimetres in length. They are rich in protein (38%) and fat (40%) and one of the most popular items on the bush tucker menu.
When eaten raw they have a nutty almond flavour and when cooked they taste like scrambled eggs with a crispy skin. The head is never eaten.
Witchetty grubs feed on the roots of the witchetty bush, a large shrub from the Acacia family. They are called 'witjuri' by some Aboriginal groups who harvest them with digging sticks.
