New study: Peaceful wasps keep colonies alive during violent queen takeovers

A new study reveals that wasp colonies experiencing violent queen replacements rely on a small number of calm, stabilising individuals to maintain essential functions. These peacekeeping wasps compensate for the chaos by contributing to vital colony tasks. The findings shed light on social behaviour and resilience in insect communities.

A newly published study has found that in wasp colonies where the queen is replaced through violent conflict, a select few calm and cooperative individuals play a crucial role in keeping the colony alive and functioning.

When a wasp colony undergoes a turbulent leadership change — with rival wasps fighting to claim dominance — the resulting chaos can threaten the survival of the entire group. However, researchers discovered that certain wasps remain unaffected by the turmoil and instead continue to carry out essential tasks such as feeding larvae and maintaining the nest.

These stabilising individuals act as a kind of biological buffer, compensating for the disruption caused by the power struggle. Without their steady contributions, the colony's core functions could collapse during the critical transition period.

The findings offer new insights into the social dynamics and resilience mechanisms of insect colonies. Scientists believe understanding how animal societies cope with internal conflict and leadership transitions could have broader implications for the study of collective behaviour in nature.
