DISTRIBUTION:

The Samia cynthia walkeri moth (wingspan: 110-120mm) flies in the People's Republic of China and on the Korean Peninsula, and wherever it has been successfully introduced.

See Samia cynthia file, as this subspecies has been equated with nominate Samia cynthia by Peigler and Naumann.

FLIGHT TIMES AND PREFERRED FOOD PLANTS:

This species probably broods continuously. Larval hosts are Cinnamomum camphora, Euscaphis japonica, Glochidion hongkongense, Lindera megaphylla, Ricinus communis, Sapium discolor and Sapium sebiferum.

ECLOSION, SCENTING AND MATING:

Moths eclose in the late morning or early afternoon and mate very readily even in the smallest of enclosures.

The female begins scenting after dark by projecting a scent gland from the posterior tip of her abdomen. Males fly into the breeze and hone in on the pheromone plume via their highly developed and sensitive antennae.

EGGS, LARVAE, COCOONS AND PUPAE:

See Samia cynthia.
