Foraging by predatory ants: A review
Insect Science, Volume 32, Issue 4, Page 1096-1118, August 2025.This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

In most species, a single queen heads the colony; in others, several queens share the task of reproduction. These different social organisations are often associated with distinct queen morphologies and life‐history strategies and occur in different ...

Social Organization Is Associated With Relaxed Selection on Worker Genes in Highly Polygyne Ants
Ecology and Evolution, Volume 15, Issue 7, July 2025.ABSTRACT Ants display a diversity of social structures reflected by differences in caste, nest, and colony organization. Previous research has shown that highly eusocial insects (Hymenoptera) exhibit genome‐wide signatures of relaxed selection due to their smaller effective population sizes.
