Sudden appearance and population outbreak of Eunica monima (Lepidoptera: Nymphalidae) on Desecheo Island, Puerto Rico

We documented the appearance and elevated abundance of the uncommon dingy purplewing butterfly, Eunica monima (Stoll) (Lepidoptera: Nymphalidae), and pronounced herbivory on its host plant Bursera simaruba (L.) Sarg. (Burseraceae) shortly after island-wide rat (Rattus rattus [L.]; Muridae) removal f...
