Graphium cyrnus in Glass Cloche 12 cm, Indonesia

Rarity and Value

Graphium cyrnus is a swallowtail butterfly of the family Papilionidae native to the tropical rainforests of Indonesia. This species is distinguished by its striking pattern of vivid yellow-green markings set against dark brown to black wings, providing effective visual signaling within the forest canopy. The wings are covered with microscopic scales containing pigments that produce their characteristic coloration, while an intricate venation network ensures both structural strength and flexibility during flight. Like other members of the genus Graphium, it is an exceptionally agile flyer capable of rapid directional changes. Large compound eyes provide excellent visual perception, and clubbed antennae contain sensory receptors that detect airborne chemical signals involved in navigation, host plant recognition, and reproduction.

Discovery and Acquisition

Graphium cyrnus inhabits humid lowland and foothill rainforests, where adults are commonly observed flying along forest paths, streams, and sunlit clearings. The species undergoes complete metamorphosis, progressing through egg, larval, pupal, and adult stages. Females lay eggs individually on selected host plants of the family Annonaceae, which provide the nutrients required for larval development. Adults feed primarily on flower nectar and frequently obtain essential minerals from damp soil and riverbanks, an important behavior supporting reproductive success. Specimens preserved for scientific and educational collections are obtained through carefully regulated and ethically managed collecting practices that maintain the integrity of their diagnostic biological characteristics.
