Biology
These moths mainly fly from August till late October, depending on the location. They feed on nectar of various flowers, including ivy and buddleia.[6][7] This species shows a migratory nature. The larvae are initially yellow, later becoming green. They can grow to a length of about 2 cms. They feed on the leaves of the host plants, mainly jasmine (Jasminum officinale), privet (Ligustrum species), Forsythia, Arbutus unedo and european olive (Olea europaea). [7] In Africa the preferred host plants are Sida rhombifolia, Grewia, Helicteres isora, Schima noronhae and Randia scortechinii. [2] The larvae are considered a pest of olive fields, as they attack the leaves and fruits. The final instar of the larvae spins some leaves together and form a silky cocoon to pupate.[5]
