Swarming bacteria are self-propelled cells that move on surfaces in large groups that resemble flocks. However, in bacteria, isolated individuals cannot move, which differentiates them from other active systems. Here, the authors show that local reduction in water temporarily traps solitary cells, which also affects the arrangement of the flagella.
