SummarySmall colonies consisting of a caged queen and young adult workers, ranging in number from 200 to 2800, were given 400 eggs to rear. Positive correlations were found between the numbers of workers and the adult life-span and dry weight of worker progeny they reared. Dry weight and life-span were also positively correlated. It is suggested that a nutritional factor is involved. Syrup, pollen and water were provided in a flight cage.
