  abstract = {{A}ggregation behaviour is the tendency for animals to group together, which may have important consequences on individual fitness. {W}e used a combination of experimental and simulation approaches to study how genetic variation and social environment interact to influence aggregation dynamics in {D}rosophila. {T}o do this, we used two different natural lines of {D}rosophila that arise from a polymorphism in the foraging gene (rovers and sitters). {W}e placed groups of flies in a heated arena. {F}lies could freely move towards one of two small, cooler refuge areas. {I}n groups of the same strain, sitters had a greater tendency to aggregate. {T}he observed behavioural variation was based on only two parameters: the probability of entering a refuge and the likelihood of choosing a refuge based on the number of individuals present. {W}e then directly addressed how different strains interact by mixing rovers and sitters within a group. {A}ggregation behaviour of each line was strongly affected by the presence of the other strain, without changing the decision rules used by each. {I}ndividuals obeying local rules shaped complex group dynamics via a constant feedback loop between the individual and the group. {T}his study could help to identify the circumstances under which particular group compositions may improve individual fitness through underlying aggregation mechanisms under specific environmental conditions.},
