When researchers at UCL removed the queen from tropical paper wasp colonies in Panama, the insects didn't descend into quiet despair—they exploded. Female wasps hurled themselves into violent power struggles, aggressive competition erupted across the nests, and the colony's careful social order shattered in an instant. But here's what the scientists didn't expect: the colony survived. Not because order was quickly restored, but because some wasps made an unexpected choice. While others fought brutally for dominance, a quiet group of females stepped back from the conflict altogether and kept doing the unglamorous work that keeps a colony alive—feeding the larvae, collecting food, maintaining the nest. These "compensators," as researchers named them, saved the colony by staying put while chaos raged around them.
The study, led by Dr. Owen Corbett at UCL's Centre for Biodiversity & Environment Research and published in Animal Behaviour, challenges what we thought we knew about how insect societies hold together. Most previous research has focused on temperate species in Europe and North America, insects with rigid hierarchies and predictable leadership transitions. Polistes canadensis—the tropical paper wasp examined here—operates in a far messier system. With no genetic caste system determining roles, multiple females in the colony can potentially reproduce. When the queen vanishes, several wasps see an opportunity to claim her position, triggering exactly the kind of destructive conflict you'd expect from a free-for-all. And yet these colonies didn't collapse.
What made the difference was behavioral flexibility. The researchers found no clear biological differences between the wasps who fought for dominance and those who became compensators. This suggests the two groups weren't born for different roles—instead, they made strategic choices. Some wasps calculated that fighting offered their best shot at future reproduction. Others apparently recognized that ensuring the brood's survival, which often included their own siblings, was the wiser investment. While dominance battles raged, the compensators continued their essential work in the background, keeping the colony functional long enough for a new queen to emerge.
Senior author Professor Seirian Sumner points out that this finding reshapes our understanding of cooperation itself. "While some individuals fought over dominance, others completely avoided the conflict and quietly stepped up to keep the colony running. Cooperation didn't disappear; it was redistributed," Corbett observed. In other words, crisis didn't destroy society—it transformed it. The same insects who might have invested energy in nest-building or foraging redirected it toward maintaining critical functions during upheaval.
The research drew on behavioral data originally collected during fieldwork in Panama in the early 2000s, giving scientists a rare window into how these colonies actually respond to queenlessness in nature. The findings expand our sense of how animal societies can weather leadership crises, suggesting that stability doesn't always require orderly succession or rigid rules. Sometimes it requires something stranger and more human: individuals making quiet sacrifices to keep the essentials running while others fight over the future. In times of turmoil, Sumner notes, society depends on those doing essential work in the background. "In many ways," she says, "we may be more like wasps than we realize."
