What to know about Chaos after queen loss reveals the wasps that keep colonies running

Researchers from UCL studied tropical paper wasps to understand how colonies survive the chaotic power struggles that follow the loss of a queen. The study found that 'compensator' wasps maintain colony stability by increasing their work on essential tasks while others compete for dominance.

Chaos after queen loss reveals the wasps that keep colonies running Sadie Harley Scientific Editor Robert Egan Associate Editor When the loss of a queen wasp triggers a power struggle and social turmoil, colonies can survive the upheaval thanks to helpful…

Why it matters

The findings, published in the journal Animal Behaviour, show that even in colonies where leadership succession is violent and chaotic, there are individual wasps that compensate for the upheaval by working harder on essential tasks.

Common ground

The study focuses on cooperative societies of tropical paper wasps (Polistes canadensis), found in the Caribbean, where many individuals live together but reproduction is controlled by a single dominant female.

Claim 1: “The study focuses on cooperative societies of tropical paper wasps (Polistes canadensis), found in the Caribbean, where many individuals live together but reproduction is controlled by a single dominant female.”

VERIFIED

Wikipedia confirms Polistes canadensis is a species of red paper wasp in the Neotropical realm, and specific reports on the study confirm the focus on Caribbean populations where a single dominant female controls reproduction.

Claim 3: “Most previous studies of cooperative colonies have focused on temperate species such as those found in Europe or North America that have highly ordered dominance hierarchies and predictable succession rules.”

SINGLE SOURCE

While the general context of the study implies a contrast with previous research, the provided evidence (Wikipedia entries for continents) does not specifically confirm the claim about the focus of previous cooperative colony studies on temperate species.
