The size in the Okinawa group was set as 1.00. (a) Male forewings. The number of individuals that were subjected to measurement is as follows: Okinawa (n = 97), Atami (n = 25), Musashino (n = 19), Kashiwa (n = 25), Koriyama (n = 84), and Motomiya (n = 71). (b) Female forewings. The number of individuals that were subjected to measurement is as follows: Okinawa (n = 99), Atami (n = 23), Musashino (n = 27), Kashiwa (n = 21), Koriyama (n = 63), and Motomiya (n = 87).
