Queenless ants C015 / 5724
Queenless ants. Streblognathus peetersi ants fighting for dominance in their nest. S. peetersi originates from South Africa. They are a species of ant that does not have a queen in the colony. All the worker ants are morphologically similar and are able to reproduce sexually. However, out of 100 ants in the colony only one, the Alpha, is allowed to reproduce. The Alpha is chosen through a hierarchical system of dominance asserted through fighting. Here, other workers are attempting to control the fighting by restraining a rival (right) that is trying to fight the Alpha

EDITORS COMMENTS
This print captures the intense struggle for dominance among Queenless ants (Streblognathus peetersi) in their South African nest. Unlike most ant colonies, this species does not have a queen. Instead, all worker ants possess the ability to reproduce sexually, resulting in a unique social structure. Out of the 100 ants within the colony, only one is designated as the Alpha and granted reproductive privileges. The selection process for this coveted position relies on a hierarchical system of dominance established through fierce fighting. In this image, we witness an enthralling moment as rival workers attempt to control and restrain another ant who dares challenge the reigning Alpha. The determination and strength displayed by these insects are truly remarkable. The absence of a queen allows each worker ant to develop similar morphological characteristics while still possessing sexual reproduction capabilities. This biological adaptation ensures that only the fittest individuals pass on their genes, maintaining genetic diversity within the colony. Nature's intricate mechanisms never cease to amaze us, and this photograph serves as a testament to both its complexity and beauty. Through studying animal behavior like that of these Queenless ants, scientists gain valuable insights into evolutionary processes and social dynamics within insect societies.
