The mulga apple is an Australian bush tucker food, often eaten by the Indigenous Australians of Central Australia.
The mulga apple is in fact a combination of plant and animal; the insect gall grows inside the wood of the mulga tree (Acacia aneura).
[1] Mulga apple is known as Merne ataltyakwerle in the Arrernte language of Central Australia.
Mulga trees grow in flat country and at the foot of hills.
Aboriginal Australians eat them raw or cook them in hot earth.
