モンシロチョウ
This species has white form "alba" which can be very common in some populations, while rare in others. It can be confused with other white forms of "Colias" particularly that of "Colias eurytheme". It can often be distinguished by the border pattern of both wings, though some individuals are impossible to separate without the presence of other "normal" specimens. Though they differ in flight style, the white forms of "Colias" may be confused with other pierids such as "Pieris rapae" and "Pontia protodice".
