Summary We examined the relationship between queen number and worker size in colonies of the fire antSolenopsis invicta. Worker size in monogyne colonies was significantly greater than in polygyne colonies; furthermore, polygyne colonies snowed a strong negative linear relationship between queen number and worker size. Higher queen pheromone level and/or decreased food availability accompanying an increase in queen number likely play important roles in producing the observed patterns.
