Analysis of the behavior of foundresses of a Japanese paper wasp, Polistes chinensis antennalis Pérez, was made to clarify the patterns of decision making. It was found that: (1) Foundresses postponed the next activity off the nest after being attacked by a foundress from another colony. (2) After a spiral flight, the frequency of subsequent spiral flights and patrol flights around the nest increased. (3) Following successful flesh collection, the frequency of flesh collection increased. (4) Following successful flesh collection, the time spent for a single trip of flesh collection increased. It was concluded that P. chinensis antennalis foundresses solve their dilemma between the need of nest defence and resource gathering by decision making based on intraspecific attacks and the intake of the most difficult resource to obtain.
