Greta
Glasswing Butterflies
Greta is a genus of clearwing butterflies in the family Nymphalidae, established by Arthur Francis Hemming in 1934. These butterflies are characterized by their transparent or partially transparent wings, a trait shared with other members of the ithomiine group. The genus occurs in the Neotropical region, with species distributed across Central America, South America, and the Caribbean. Notable species include Greta oto, commonly known as the glasswing butterfly, and Greta morgane, the thick-tipped greta.
Greta morgane
thick-tipped greta
Greta morgane, commonly known as the thick-tipped greta, is a day-active clearwing butterfly in the family Nymphalidae. Adults have reduced wing scaling that creates transparent areas on the wings, a characteristic feature of ithomiine butterflies. The species is widespread and common across its native range in Mexico, Central America, and the Caribbean, with occasional strays recorded in southern Texas. It was first described by Geyer in 1833 under the basionym Hymenitis morgane.
