Issued by Mozambique, this striking 15 Escudos postage stamp features Amphicallia thelwalli, a vividly patterned African butterfly admired for its bold orange and black wing markings. Part of Mozambique’s classic wildlife and entomology thematic issues, the design reflects mid-20th-century natural history illustration with strong visual contrast and fine detail. The scientific name is clearly inscribed, adding educational and taxonomic appeal for thematic collectors. This stamp is highly desirable for butterfly, insect, African fauna, and zoological collections, and fits well into broader biodiversity or colonial-era Mozambique assemblages.
