Animal Behavior: Socially Distanced Wasps Learn About Rivals

Area of Science:

• Animal behavior
• Neuroethology
• Social cognition

Background:

• Understanding social dynamics is crucial for survival and reproduction.
• Cognitive complexity of social learning is debated, especially in insects.
• Third-party social learning, observing interactions between others, is key.

Purpose of the Study:

• To investigate if paper wasps (Polistes spp.) can learn about the fighting abilities of conspecifics through observation.
• To determine the extent of social network understanding in insects.

Main Methods:

• Observational learning paradigm with paper wasps.
• Controlled exposure to staged fighting interactions between unfamiliar wasps.
• Subsequent assessment of individual wasp behavior towards previously observed individuals.

Main Results:

• Paper wasps demonstrated avoidance of individuals previously observed losing fights.
• Wasps approached individuals previously observed winning fights more readily.
• This indicates information about fighting outcomes was acquired and utilized.

Conclusions:

• Paper wasps exhibit third-party social learning capabilities.
• Insects possess a more sophisticated understanding of social networks than previously assumed.
• This challenges notions of cognitive limitations in small brains regarding social information processing.
