This beautifully illustrated 1969 Romanian definitive features the striking Pericallia matronula, a colorful tiger moth known for its vivid yellow and brown wings and bright red thorax. Issued by Posta Romana, the stamp is part of a popular fauna-themed series showcasing native species. The clean aqua background highlights the moth’s detailed patterning, making it a standout thematic item for collectors of insects, lepidoptera, and Eastern European issues. A fine example of Romania’s mid-20th-century natural history designs.
