Myrmecia pyriformis - Brown Bull Ants
Myrmecia ants are a conspicuous element of the Australian insect fauna, and with the exception of a rare New Caledonian species they are found nowhere else. These large, elegant ants are regarded as having many primitive characteristics, including a relatively simple social structure, little morphological difference between queens and workers , and a basic foraging strategy where ants hunt for food individually using primarily visual cues.
