Abstract: | Summary Raiding behavior of the Japanese slave-making antPolyergus samurai was investigated in the field. Raiding trips occurred from early June to early September. A raiding column of several hundreds workers would rush into a target nest and rob mainly worker pupae of the host species,Formica (Serviformica) japonica. Most trips occurred on sunny days. Air temperature, soil temperature, relative humidity, and radiation energy at the ground surface were significantly different between days with and without raiding trips. Nuptial flights occurred on hot, sunny days, and mostPolyergus colonies released alates simultaneously. Behaviors of newly mated queens are also provided and are compared with otherPolyergus species. |
