This $0.05 stamp from Portuguese Guinea (modern-day Guinea-Bissau) features a vivid depiction of the longhorn beetle Analeptes trifasciata. Issued by Correios de Guiné Portuguesa and printed by Courvoisier S.A., it highlights the colony’s natural biodiversity through finely detailed insect artwork. The bold yellow background and contrasting red-black bands of the beetle exemplify the distinctive natural history design style common to mid-20th century Portuguese colonial issues. A classic collectible for entomology and colonial Africa themes.
