Using a unique interconnected experimental system, the authors investigate the effect of sex ratio on dispersal in a butterfly. Controlling individual and population characteristics with this approach allows specific determination of the effect of varying sex ratio on the dispersal response, which is a breakthrough in knowledge of the dispersal process that would have been extremely difficult to achieve in nature.
