The pugnacious ants live in arid environments just on the edge of human settlements and fight with every ant they meet.
They are big ants with robust heads on their majors. In contrast Anoplolepis gracilipes is slender and agile, but has a similar personality.
Very successful ants tend to be smaller, hardy, able to exploit human food bounties, and fast a reproduction.
So, it was the dainty and slender pugnacious ant that would travel the world with plants and soil causing chaos. 3/
