We investigated if there is an inherent size advantage among competing queens by staging paired duels in artificial fighting arenas. We raised queens of either highor low-reproductive quality and paired queens to maximize the weight difference between them. We found that heavier queens were significantly more likely to survive than lighter queens. Given that heavier queens do not seem to have an advantage in vivo, these results suggest that there may be opposing levels of selection acting on queen duels at the individual and colony levels.}, number={2}, journal={ETHOLOGY ECOLOGY & EVOLUTION}, author={Tarpy, D.
