About the Gaudy Commodore
Precis octavia, the gaudy commodore, is a species of butterfly in the family Nymphalidae. It is native to Africa. Precis octavia was first described by Pieter Cramer in 1777. The nominate subspecies (Precis octavia octavia) flies from West Africa, through Cameroon, Gabon, Republic of Central Africa, Republic of the Congo, Democratic Republic of the Congo, north to Sudan, Ethiopia, Somalia, and Zimbabwe. It has a wet season form—orange with a pinkish flush and black markings on the upperside—and a dry season form—shining blue with a vivid red band on the hindwing. In his authoritative 2-vol. book "Butterflies of West Africa", Torben B. Larsen states "I believe this species has the most spectacular seasonal dimorphism of any butterfly, and the two morphs were [first] described as distinct species."
The southern subspecies (Precis octavia sesamus) also has two seasonal forms: a summer form (natalensis) which is red with black markings, and a winter form (sesamus) which is blue with a line of red markings on the wings. The winter form is slightly larger than the summer form. In both forms the males and females are alike, however the females are slightly larger.
