Swarm Intelligence (SI) is a collective behavior that emerges from interaction between
individuals in a group. Typical SI includes fish schooling, ant foraging, bird migration, and so …

Workers of the Argentine ant, Iridomyrmex humilis, start to explore a chemically unmarked
territory randomly. As the exploratory front advances, other explorers are recruited and a trail …

How do ant colonies get anything done, when no one is in charge? An ant colony operates
without a central control or hierarchy, and no ant directs another. Instead, ants decide what …

Both human and insect societies depend on complex and highly coordinated infrastructure
systems, such as communication networks, supply chains and transportation networks. Like …

Schools of fish, flocks of birds, and swarms of insects are examples of three-dimensional
aggregation. Covering both invertebrate and vertebrate species, the authors investigate this …

The trail-laying behaviour of foragers of the ant Lasius niger was observed in the laboratory
on a 20 cm bridge between the nest and the food source. We measured both the frequency …

For robot swarms to operate outside of the laboratory in complex real-world environments,
they require the kind of error tolerance, flexibility, and scalability seen in living systems …

We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using
a novel imaging and analysis technique we estimated pheromone concentrations at all …

One of the most striking features of an ant colony's behaviour is its capacity for the spatial
organisation of foraging activity. The use of trail pheromone to guide fellow workers in the …

The relative contribution of visual and chemical components in the orientation of Lasius
niger and Iridomyrmex humilis (Argentine ant) workers during mass recruitment to newly …
