Ants are highly successful dominating invertebrate ecosystems in many part of the world. Key to their success is their sociality. This allows them to work collectively to perform extraordinary behaviours and build extraordinary structures. A little-known aspect of ant nesting behaviour is polydomy. In a polydomous colony a single ant colony inhabits inhabits several spatially separated, but socially connected nests. This stratergy is common in ants, espcially in many ecologically dominant and invasive species. I studied this behaviour in the red wood ant Formica lugubris. Using a variety of methods we have attempted to understand how this system is organised, specifically focusing on how resources are redistributed through this complex system. The methods we use include: network analysis, individual marking, Radio-Frequency IDentification (RFID) tagging, fat analysis and trail/nest observations.
