Yellow Swallowtail Butterfly on Yellow Flowers — Postcard

A yellow swallowtail spreads its wings wide across a cluster of small yellow blooms, showing off every black vein and the delicate tails on its hindwings. Part of the “Summer Stories” postcrossing series, photographed in warm, watercolor-toned light.

• Size: 10×15 cm
• Density: 350 g/m²

Good for the postcrossing friend who stops to watch every butterfly they pass.
