After about thirty seconds of the display, the male will attempt copulation. This "grazing iridescence" is brought about through diffraction of light (after back-reflection) by the wings' extremely steeply-set, multilayered rib-like scales (rather than the ridge-lamellae of most other iridescent butterflies, such as Morpho species).  The sexual dichromatism functions in mate recognition by the use of photoreceptors. They are found across tropical Asia, mainland and archipelagic Southeast Asia, and Australasia.

It is found in northern India, Nepal, Burma, China, Thailand, Laos, Vietnam, Taiwan, Cambodia, peninsular Malaysia and Indonesia.

Following insemination, it is common for the male Ornithoptera to produce a mating plug, which will seal the ostium bursae and prevent remating by the female, as new sperm is unable to enter the opening. After mating, females immediately begin to seek appropriate host plants; climbing vines of the genera Aristolochia and Pararistolochia (both in the family Aristolochiaceae) are sought exclusively.

Gyanandromorphism is a very rare condition in which an organism simultaneously expresses both male and female phenotypes. After consideration, the male may choose to hover twenty to thirty centimeters above the female, displaying the bright yellow marking on its hindwings. The plug does not impede oviposition and may stay in place for the duration of the female's life.
