It included several stages, the duration of which was assessed by direct observation on experimental nests set up by fission of natural, queenless, colonies. The results show that two phases of adult activity alternated while cohorts of brood developed synchronously. During the statary phase, virgin workers laid diploid eggs simultaneously but no foraging activity was observed until the following phase which began after the callow workers of the previous brood cohort emerged and the eggs hatched. During this foraging phase, workers explored intensively for food while larvae matured synchronously. Biometrical measures allowed to determine that three larval instars occurred in this species. While larvae started pupation, workers stopped to forage and the next statary phase took place, during which a new cohort of eggs was laid and pupae matured. This repeated phasic reproductive cycle where adult activity and development of the brood are synchronised reminds that of true army ants (subfamily Ecitoninae which brings new arguments in favor of a filiation between both groups.1 aRavary, F1 aJaisson, P  uhttps://antkey.myspecies.info/en/content/reproductive-cycle-thelytokous-colonies-icerapachys-biroi-iforel-formicidae-cerapachyinae01295nas a2200181   4500008004100000245007900041210006900120260001000189300001400199490000700213520070200220100001400922700001600936700001600952700001600968700001500984856011400999       2007                        eng d00aIndividual experience alone can generate lasting division of labor in ants0 aIndividual experience alone can generate lasting division of lab  cAug 7  a1308-13120 v173 aSEE: Comment in: Curr. Biol. 2007 Sep 4; 17(17):R766-8.*[We show that ant workers engaged in distinct functions in accordance with their previous experience.  When individuals were experimentally led to discover prey at each of their foraging attempts, they showed a high propensity for food exploration.  Conversely, foraging activity progressively decreased for individuals who always failed in the same situation.  One month later, workers that previously found prey kept on exploring for food, whereas those who always failed, specialized in brood care.  Thus, it appears that individual experience can strongly channel the behavioral ontogeny of ants to generate a lasting division of labor.]1 aRavary, F1 aLecoutey, E1 aKaminski, G1 aChâline, N1 aJaisson, P  uhttps://antkey.myspecies.info/en/content/individual-experience-alone-can-generate-lasting-division-labor-ants
