Idea leuconoe
One of Japan's largest butterflies, white with black veins and spots, famous for its golden chrysalis. Completes its life cycle indoors as long as the host plant Parsonsia alboflavescens is available, so it is widely reared in insectariums and schools.
Idea leuconoe ranges from Southeast Asia to Taiwan and, in Japan, the Ryukyu Islands south of Kikaijima and Yoron; it is the prefectural butterfly of Okinawa. With a forewing of about 7cm and a wingspan reaching 13cm, its slow, gliding flight on white wings marked with black veins and spots has earned it the nickname 'lady of the south'. Larvae feed on Parsonsia alboflavescens and Tylophora (Apocynaceae), storing alkaloids that make larvae, pupae and adults toxic; the black-and-white pattern is aposematic. The 4-5cm chrysalis gleams gold through structural colour. At Tama Zoological Park, rearing at about 26C gives a larval period of about 20 days and a pupal period of 15-20 days, with the gold brightest for the first 10 days. Adults live 2-3 months, up to six months under good conditions, and breed year-round. Because the life cycle completes in a small space, insectariums and zoos across Japan maintain colonies, and larvae and golden pupae are traded for education and display. Securing the host plant is the prerequisite for keeping.

Larvae eat Parsonsia alboflavescens and Tylophora leaves; adults take nectar
Insectariums rear at about 26C. As a subtropical species it needs heating in winter; pupae kept cooler emerge later.
Eggs are laid on the underside of the host plant; egg about 5 days, larva about 20 days, pupa 15-20 days. Adults mate and lay readily in a screened cage.
Adults are gentle and are kept in groups in greenhouses. Larvae consume a lot of foliage, so limit numbers per host plant.
Adults live 2-3 months, up to six months. Egg to adult takes about 40 days, allowing continuous year-round rearing.
Larvae, pupae and adults are toxic from host-plant alkaloids. Colonies collapse if the host plant runs out, so secure plants before rearing.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Tree Nymph Butterfly is 26℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Tree Nymph Butterfly is Adults 2-3 months (up to six months in good conditions); egg to adult about 40 days. With proper care and nutrition, they can live a long and healthy life.
Tree Nymph Butterfly typically reaches Wingspan 12-14cm (forewing about 7cm); final-instar larva about 7cm as an adult. Size may vary depending on care conditions and individual genetics.
Tree Nymph Butterfly feeds on: Larvae eat Parsonsia alboflavescens and Tylophora leaves; adults take nectar. Aim for a balanced diet with appropriate feeding frequency.
