Why is the *Nylanderia fulva* ant commonly called the "yellow crazy ant"?

Answer

Because of their astonishingly erratic and unpredictable movements.

The common name originates directly from the signature lack of linear travel; they dart about in seemingly random, unpredictable directions rather than following established trails.
