• The early phase of colony formation of a formicine ant Formica (Serviformica) japonica MOTSHULSKY was experimentally investigated. The artificially inseminated queens laid eggs normally and reared them. Oviposition of the first brood continued for four to five days. The egg-laying ceased before the first egg hatched, which suggested that queens stopped egg-laying by a self-regulating mechanism. The second batch of eggs was layed when the previous brood reached the prepupal or pupal stage. This synchronization gradually disappeared as the number of workers increased in the nest. The egg-laying behaviour of queens after the workers emerged depended on the number of assistant workers present. Those receiving help from about 10 workers became rather egg-laying machines for colony growth. Self-regulating egg deposition by queens and its dependence on the number of workers suggest that colonizing success and successful colony growth often depend on efficient allocation of available resources.
