The pre‐calling behavior of female adults of the common cutworm, Spodoptera litura (Lepidoptera: Noctuidae) collected in southern Japan and southeastern Asian countries was investigated. Most females started calling on days 1–4 after adult emergence. In three populations obtained in Saga prefecture in Kyushu mainland, Japan, two different patterns of pre‐calling period (PCP) were observed: one was the above‐mentioned pattern shown by most individuals, and the other was a pattern in which females sexually matured within several hours after emergence. Diel periodicity was shown in the time of calling activity, and its pattern varied among the populations. Pre‐calling period was stable over successive generations in the laboratory.
