📖 1. Overview
The Asian swallowtail is a large butterfly named in Korean for the black and yellow markings lined up like stripes on a tiger's back, living throughout the Korean Peninsula as well as the Russian Far East, Japan, eastern China, and Taiwan.
🦴 2. Anatomy & Morphology
With a wingspan of 80–120 mm, it has yellow markings on black wings and indigo and red spots along the outer margin of the hindwing. Distinct yellowish-white stripes in the forewing discal cell distinguish it from the Old World swallowtail.
🔍 3. Ecology & Behavior
It occurs 2–3 times in 1 year—appearing from late March to May, June to July, and August to October—and overwinters as a pupa. After mating, females lay eggs singly on the undersides of leaves or stems of Rutaceae plants such as trifoliate orange, citrus, prickly ash, and Amur cork tree.
🇰🇷 4. Connection to Korea
The National List of Species of Korea records that it is widely distributed nationwide and inhabits the entire Korean Peninsula.
