Abstract: A butterfly rearing kit including an enclosure in which metamorphosis of a butterfly larva or butterfly chrysalis into a butterfly can be carried out. Basically, the kit includes first and second transparent plastic domes having open bases that can be releasably fastened together to form an enclosure. The enclosure may be supported by a third dome secured to the enclosure with the open base extending downwardly or on a rod extending out through said second dome. In one embodiment, a cup is provided for a butterfly larva with a cap to which the larva attaches the hanging chrysalis. The cap can be removed from the cup and placed over an opening in the top of the enclosure, so that final metamorphosis to a butterfly occurs in the enclosure. The kit preferably includes a moss like material along the bottom of the enclosure and butterfly larva food where the process starts with a larva.
