Queenless wasp colonies in the Caribbean suddenly face violent power struggles. But surprisingly, some wasps quietly keep the colony running during the chaos.

Tropical paper wasps (Polistes canadensis) build their colonies around a single dominant queen. However, if she disappears, several other females can reproduce themselves. This means multiple wasps may compete to take her place. Researchers removed queens from established colonies and observed what happened next.

The results were immediate. Female wasps began aggressively competing for dominance, and the colony's normal social structure quickly unraveled. Instead of an orderly transfer of leadership, the colonies entered a period of intense conflict involving many individuals.

Despite the chaos, the colonies did not collapse. Researchers discovered that some wasps took on a crucial role during the unrest. These 'compensators' focused on essential tasks like collecting food and caring for developing young. They helped offset the damage caused by the conflict.

The study found no clear biological differences between the wasps involved in aggressive competition and those acting as compensators. This suggests that these behaviors may reflect strategic choices instead of fixed social roles.

Why It Matters

This research shows that even during chaos, some individuals can work together to keep society running. This is important for students in India to understand because it highlights the importance of cooperation and teamwork in overcoming challenges.

Key Facts

• Queenless wasp colonies in the Caribbean face violent power struggles when a queen disappears.
• Some wasps quietly step in to keep the colony running during the chaos, known as 'compensators'.
• The study found no clear biological differences between aggressive and compensatory wasps, suggesting strategic choices over fixed social roles.
• Tropical paper wasps (Polistes canadensis) are a type of social insect that builds colonies around a single dominant queen.
• The study was published in the journal Animal Behaviour in 2026.
