The witchetty grub (also spelled witchety grub or witjuti grub) is a term used in Australia for the large, white, wood-eating of several . In particular, it applies to the larvae of the Cossidae Endoxyla leucomochla, which feeds on the roots of the Acacia kempeana (after which the grubs are named) that is widespread throughout the Northern Territory and also typically found in parts of Western Australia and South Australia, although it is also found elsewhere throughout Australia.
The term can also apply to larvae of other cossid moths, ghost moths (Hepialidae), and longhorn beetles (Cerambycidae). The term is used mainly when the larvae are being considered as food. The grub is the most important Entomophagy of the desert and has historically been a staple in the diets of Aboriginal Australians.
These grubs live in trees. They can also be found in black wattle trees, and are considered to be the reason why wattles die within 10 to 15 years. The roots of the Acacia kempeana shrub are another source of the grubs.
When held, as a defence mechanism, the grubs will secrete a brown liquid.
Witchetty grubs have also been imitated in confectionary and were a common Australian lolly.
