Leaderless Ants Create Super Efficient Transport Networks

leaderless ants

Argentine ants connect three nests in an empty arena via the shortest possible network.

Ants are able to connect multiple sites in the shortest possible way, and in doing so, create efficient transport networks, according to a University of Sydney study published in the Journal of the Royal Society Interface.  The research also revealed the process by which the ants solve network design problems without the help of a leader.

The Ant Queen’s Chemical Crown Keeps Her Workers Infertile

The ant queen is the only one that reproduces unless she dies or is removed.

The defining feature of social insects is that societies contain queens, which specialise in laying eggs, as well as workers, which are mostly infertile but take care of the offspring and the nest. However, when the queen dies or is re-moved, workers begin laying eggs of their own. Previous observations have suggested that queens possess a specific pheromone which keeps the workers infertile, but the pheromone has never been identified except in the well-studied honeybee.
