The larva that feeds on Plectranthus barbatus flowers is either the caterpillar of Hypolimnas anthedon or Junonia orithya, but most likely the caterpillar of Junonia orithya.
Thanks for your update about metamorphosis. Pardasena virgulana Mabille, 1880 is the species documented in the video. It is a species of moth in the Nolidae family.
And it's a request, from next time please try to post exact date and location information along with your documentation. It really helps to sort out species.
Yes, I agree with Sayak, it is Pardasena virgulana. It is a polyphagous species. https://africanmoths.com/pages/z%20MADAGASCAR/NOLIDAE/m%20pardasena%20virgulana.html
Is it strange to be detected in Saudi Arabia as the insect was observed only in Africa in Kenya, La Reunion, Madagascar, Malawi, Mauritius, Mozambique, Nigeria, Sierra Leone, South Africa, Tanzania, Uganda, Zambia and Zimbabwe?
Pardasena virgulana has been primarily documented in various African countries. However, its presence has also been recorded in Saudi Arabia. Therefore, detecting Pardasena virgulana in Saudi Arabia is consistent with its known distribution and not particularly unusual.
