African migrant

Catopsilia florella
Catopsilia florella, the African migrant, African emigrant, or common vagrant, is a butterfly of the family Pieridae. It is found in Africa (including Madagascar), Arabia (United Arab Emirates, Saudi Arabia, Oman) and the Canary Islands. Like Catopsilia pomona, this species also has a habit of migration.
Many early authors mentioned the presence of this species in Asia; but those were probably due to confusion arises as Catopsilia pyranthe females exhibit a lot of seasonal variations. Catopsilia florella is not included as a species in India in any recent checklists.
The wingspan is 54–60 mm for males and 56–66 mm for females. Adults are on wing year-round. From South Africa, adults migrate from summer to autumn. They fly in a north-eastern direction.
The larvae feed on Senna occidentalis, Senna septentrionalis, Senna petersiana, Senna italica, Cassia javanica, and Cassia fistula.
