Filodes costivitralis, the window pearl, is a moth of the family Crambidae. It is found in Réunion, Madagascar, Mauritius, and central, southern and eastern Africa.[1] [2] The larvae feed on Hibiscus species and Thunbergia species, including Thunbergia grandiflora.
Occasionally the adults drink tear liquid from cattle, and can be a vector of animal diseases.[3]
