Commercial butterfly breeding or captive butterfly breeding is the practice of breeding butterflies and moths in controlled environments to supply the stock to research facilities, universities, zoos, insectariums, elementary and secondary schools, butterfly exhibits, conservation organizations, nature centers, individuals, and other commercial facilities. Some butterfly and moth breeders limit their market to wholesale customers while other breeders supply smaller volumes of stock as a retail activity. Some small scale and larger scale breeders limit their businesses to the provision of butterflies or moths for schools. Others provide butterflies to be used and released in commemorative events. [1] The release usually occurs in the natural range of the butterfly.

History

5000 BC to 1976

Sericulture in Hoi An, Vietnam

Commercial breeding of Lepidoptera has a long history. The Bombyx mori (Latin: "silkworm of the mulberry tree"), the practice of breeding silkworms for the production of raw silk, also known as Sericulture, has been underway for at least 5,000 years in China. [2] [3] It is dependent on humans for its reproduction and does not occur naturally in the wild. The silkworm was domesticated from the wild silkmoth Bombyx mandarina, which ranges from northern India to northern China, Korea, Japan, and the far eastern regions of Russia. The domesticated silkworm derives from Chinese rather than Japanese or Korean stock. [4] [5] Silkworms were unlikely to have been domestically bred before the Neolithic age; before then, the tools required to facilitate the manufacturing of larger quantities of silk thread had not been developed. The domesticated B. mori and the wild B. mandarina can still breed and sometimes produce hybrids. [6] :342

1977–present

Serious commercial breeding activity began in 1977. At this time, the tomato industry on Guernsey had become bankrupt and unused greenhouses remained. [7] An entrepreneur purchased a vacant greenhouse and filled it with tropical plants – creating a tropical jungle environment. Butterflies from Asia were acquired and set free within the enclosure. The newly constructed enclosure contained a waterfall and a small stream. The structure was then opened to the public. [ citation needed ] In 1977, there was no access to commercial butterfly breeders in tropical regions, so the stock was obtained from amateur lepidopterists who periodically provided a few dozen butterflies to the exhibit. The Guernsey butterfly exhibit was a commercial success. Butterfly exhibits quickly gained a positive reputation with investors. They were seen as novel commercial activities generating a return in a short time. [ citation needed ]

The butterfly exhibit industry continued to expand in 1980 and until 1988 in the United Kingdom. New exhibits were started every year. Some were separate exhibits, while others were part of wealthy estates. Other commercial exhibits were added onto already existing businesses, such as garden supply centers. [ citation needed ]

The new butterfly exhibits had varying results. Some exhibits were not as labor-intensive and were started hastily in order to maximize short-term profit. One owner pinned his dead butterflies onto flowers to cut costs. [ citation needed ] Other exhibitors sought to improve their exhibits to increase the public's enjoyment. These developed exhibits began to set long-term profit goals. Commercial butterfly breeding and exhibitions have developed rapidly over the past 20 years, putting unprofitable exhibitors out of business.

European butterfly exhibits are now supplied by regulated butterfly brokers. In 1980 one full-time professional distributor supplied live butterfly stock - Entomological Livestock Supplies. Other suppliers have formed since then. Brokers import butterfly pupae from around the world. Leading producers of butterfly pupae are the United States, El Salvador, Suriname, Ecuador, Malaysia, Kenya, Philippines, Thailand, and Costa Rica. [8]

Butterfly exhibits and commercial/captive breeding have flourished in Canada and the United States. North America's largest butterfly exhibit is The Niagara Parks Butterfly Conservatory. It opened in 1996 and is a $15 million facility. The conservatory can accommodate up to 300 visitors per hour. The glass dome that contains the conservatory is 1,022 square meters (11,000 sq ft) in size with 180 meters (590 ft) of paths inside the greenhouse.

Breeding Practices and Procedure

Some breeders are able to generate substantial income. Large operations require large, paid, and trained staff.

Training and Certification

Commercial and captive breeders often begin their operations after raising butterflies as a hobby and then expanding this into a business. Many butterfly breeders consider themselves to be hobbyists and limit their breeding to providing butterflies to their friends, families, and schools at no cost. [1]

Commercial and hobbyist breeders are often members of the International Butterfly Breeders Association (IBBA) and the Association for Butterflies (AFB). [9]

A breeder typically begins their operation by obtaining breeding stock from a reputable supplier of healthy stock screened for the disease. Most breeders in southern states are able to overwinter their stock enabling them to provide butterflies to customers year-round if the ambient temperatures are supportive of flight and the survival of the butterfly. Many breeders in northern latitudes that experience cold winters or repeated frosts shut down for the winter months.

Breeders are trained in infection control, health monitoring, disease prevention, laboratory techniques, and biological pest control. [10] [11]

Methods

Captive breeders employ cost-effective and sustainable methods of plant propagation needed to provide larval food for their stock. Greenhouses, hydroponics, drip irrigation, and organic-based methods control disease costs and create high plant yields. Pesticides are not used in the breeding of stock. [ citation needed ]

Captive breeders reduce the exposure of laboratory-bred stock to naturally occurring predators, parasites, and diseases that affect wild stock by rearing butterflies in enclosed environments.

The butterfly and moth larvae are typically raised in containers in various densities dependent upon the predetermined protocols. Some butterfly larvae are best raised in lower densities and others at higher densities. Breeding operations can include other environmental controls such as humidity and temperature. [ citation needed ]

Larger breeding operations require hiring employees who are then trained to grow larval food maintain the grounds, sustain controlled environments, make shipments, advise receiving organizations on the proper care of butterfly stock.

Host plants

Breeders grow host plants for the larvae that they are raising. Many of them have greenhouses enclosed to protect the food plants from being contaminated by parasites, predators, and adverse environmental conditions. The plants raised in these greenhouses grow faster and stronger due to the methods employed by the breeders.

Different species of butterflies need different host plants. Some larvae are limited to one type of host plant while other larvae are referred to as generalists and are able to use a variety of host plants.

Proper care for the host plants is important to ensure a large and healthy stock. Microsporidium, a fungal parasite that originates from host plants, can kill 100% of larvae hatched from infected eggs.[ citation needed ] This disease is transferred from larvae to adults. Infected larvae initially show no visible symptoms. This infection is detected with a microscope.

National Regulation (US)

The United States Department of Agriculture (USDA) regulates the interstate shipment of captive/commercially bred butterflies. The USDA allows shipments to areas and regions within the natural range of the butterfly. Some states have their own regulations to govern the shipping and release of commercially bred stock. Canada also regulates the shipment of butterflies. The United States Department of Agriculture does not regulate butterfly releases and breeding done within the boundaries of a state. [ citation needed ]

Butterflies, moths, and almost all other species of animals and plants are not allowed to be removed from federal land and are not considered a source of butterflies for release. Fines are applied to those who collect from federal lands. [ citation needed ]

Only six species of butterflies can be shipped across state lines in the United States. Butterfly houses, conservatories, and exhibits can receive butterflies and moths from outside of the United States. These shipments are regulated and do not allow the release of butterflies from these controlled environments. The shipments are also regulated by the United States Department of Agriculture. The same operations do receive shipments of native butterflies from breeders within the United States who have the proper permits.[ citation needed ]

Commercial Activity

Market-driven competition determines the price of butterflies supplied to customers and wholesalers. [1] Some commercial breeders limit their shipments to wholesale customers like butterfly houses, conservatories, and exhibits. Other breeders shipped directly to customers who use the butterflies in various venues. [1]

Breeders ship stock in all ages of the life cycle of the butterfly to elementary and secondary schools throughout the United States, subject to the shipping regulations of the USDA. [1]

Event organizers sometimes purchase butterflies from breeders to be released during events such as funerals, hospice activities, bar mitzvahs, 9/11 memorial events, and weddings.

Captive-bred stock is purchased by researchers. [12]

Captive butterfly breeding has been used to replenish extirpated populations of butterflies. An example of this was the commercial breeding of the Schaus' Swallowtail, also known as Papilio aristodemus. This species of butterfly is native to the Florida Keys and in 2012, there were only four left in the wild. [13] Their population has been successfully restored since then by captive butterfly breeders at the University of Florida. The breeding program produced more than a thousand larvae within two years. [13]

International Economic Impact

Butterfly farming has been successful in increasing economic opportunities for local people in Ecuador and Costa Rica. Butterfly farming also promotes conservation activities and education. [3] [14]

Commercial butterfly breeding in developing countries is a practical and sustainable field. It is environmentally non-destructive, uses available raw materials, economically and environmentally sustainable. Commercial butterfly breeding can be considered ethical because it does not harm or degrade the people involved in it or the environment that sustains it.

In contrast to the clearcutting of natural habitats, a butterfly farming operation is dependent upon native plant species. A butterfly farmer keeps areas of land intact with naturally occurring vegetation. Commercial butterfly farmers plant native plants on the property, providing food sources for the caterpillars.

Commercial butterfly breeders generate employment and support the rural economy. It inhibits rural to urban movement patterns. [ citation needed ]

Some national governments in these countries have established protections for the maintenance of butterfly ranching. In Papua New Guinea, the Insect Farming and Trading Agency oversees and regulates sustainable butterfly ranching. [15] [16] Commercially bred monarchs migrate to overwintering sites in Mexico, expanding the knowledge of migratory behavior. [17]

Potential Risks

Some are concerned with the possible negative effects of captive breeding. [18]

Reduction of biodiversity

Commercial and captive breeding releases of painted lady and monarch butterflies have been criticized for their potential of reducing biodiversity in wild populations. The homogeneity of the genome of the monarch has been determined and is 'unprecedented' across its worldwide range. [19]

This is why a recent major goal of captive breeding programs is the preservation of maximum genetic variability within a species. Sampling butterflies from several genetic lineages can help promote biodiversity within captive bred groups. [20]

Disease and parasite transmission

Butterfly releases have been criticized for having the potential of spreading disease and promoting the proliferation of more virulent strains of parasites.

Parasitic strains of Ophryocystis elektroscirrha have been found to be the most virulent in the western population of the monarch butterfly. When monarchs in the eastern population were inoculated with the parasite found in the western population, the eastern monarchs were more resistant to the parasite than western monarchs. When monarchs from the western population were inoculated with the parasite found on eastern monarchs, no significant differences were observed.[ citation needed ] The degree of variation can be attributed to different variations in the host and parasitic conditions. [21]

Overutilization

Butterfly releases have been criticized because the monarch butterfly population is being overutilized.[ citation needed ]

Breeders often use wild monarch butterflies to initiate their seasonal breeding. The released butterflies add to the population of wild monarchs.[ citation needed ]

Petition to have the monarch butterfly designated as threatened under the Endangered Species Act

Adoption of the designation to have the monarch butterfly as threatened would prohibit the release of commercially bred monarchs, subject to substantial fines and penalties. [22]

Lepidoptera is an order of insects that includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing ten percent of the total described species of living organisms, and placed in 126 families and 46 superfamilies. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most species-rich orders, along with the Hymenoptera, Diptera, and Coleoptera.

Moths make up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and diurnal species.

<i>Bombyx mori</i> Moth mainly used in the production of silk

The domestic silk moth is an insect from the moth family Bombycidae. It is the closest relative of Bombyx mandarina, the wild silk moth. The silkworm is the larva of a silk moth. The silkworm is of particular economic value, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other species of mulberry, and even leaves of other plants like the osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths are not as commercially viable in the production of silk.

The fancy rat is the domesticated form of Rattus norvegicus, the brown rat, and the most common species of rat kept as a pet. The name fancy rat derives from the use of the adjective fancy for a hobby, also seen in "animal fancy", a hobby involving the appreciation, promotion, or breeding of pet or domestic animals. The offspring of wild-caught specimens, having become docile after having been bred for many generations, fall under the fancy type.

<span class="mw-page-title-main">Selective breeding</span> Breeding for desired characteristics

Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals.

Husbandry has a long history, starting with the Neolithic Revolution when animals were first domesticated, from around 13,000 BC onwards, predating farming of the first crops. By the time of early civilisations such as ancient Egypt, cattle, sheep, goats, and pigs were being raised on farms.

<span class="mw-page-title-main">Monarch butterfly</span> Milkweed butterfly in the family Nymphalidae

The monarch butterfly or simply monarch is a milkweed butterfly in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 cm (3.5–4.0 in). A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing.

Purebreds are "cultivated varieties" of an animal species achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be "pedigreed". Purebreds breed true-to-type which means the progeny of like-to-like purebred parents will carry the same phenotype, or observable characteristics of the parents. A group of purebreds is called a pure-breeding line or strain.

Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, overhunting or fishing, pollution, predation, disease, and parasitism.

<i>Bombyx</i> Genus of moths

Bombyx is the genus of true silk moths or mulberry silk moths of the family Bombycidae, also known as silkworms, which are the larvae or caterpillars of silk moths. The genus was erected as a subgenus by Carl Linnaeus in his 10th edition of Systema Naturae (1758).

<i>Samia cynthia</i> Species of moth

Samia cynthia, the ailanthus silkmoth, is a saturniid moth, used to produce silk fabric but not as domesticated as the silkworm, Bombyx mori. The moth has very large wings of 113–125 mm (4.4–4.9 in), with a quarter-moon shaped spot on both the upper and lower wings, whitish and yellow stripes and brown background. There are eyespots on the outer forewings. The species was first described by Dru Drury in 1773.

The Japanese quail, also known as the coturnix quail, is a species of Old World quail found in East Asia. First considered a subspecies of the common quail, it is now considered as a separate species. The Japanese quail has played an active role in the lives of humanity since the 12th century, and continues to play major roles in industry and scientific research. Where it is found, the species is abundant across most of its range. Currently, there are a few true breeding mutations of the Japanese quail. The varieties currently found in the United States include Pharaoh, Italian, Manchurian, Tibetan, Rosetta, along with the following mutations: sex-linked brown, fee, roux, silver, andalusian, blue/blau, white winged pied, progressive pied, albino, calico, sparkly, as well as non-color mutations such as celadon.

Bombyx mandarina, the wild silk moth, is an insect from the moth family Bombycidae. It is the closest relative of Bombyx mori, the domesticated silk moth. The silkworm is the larva or caterpillar of a silk moth. Unlike the domesticated relative which is unable to fly or indeed persist outside human care, the wild silk moth is a fairly ordinary lepidopteran. Its main difference from the domesticated taxon is the more slender body with well-developed wings in males, and the dull greyish-brown colour.

<span class="mw-page-title-main">Conservation biology of parasites</span>

A large proportion of living species on Earth live a parasitic way of life. Parasites have traditionally been seen as targets of eradication efforts, and they have often been overlooked in conservation efforts. In the case of parasites living in the wild – and thus harmless to humans and domesticated animals – this view is changing. The conservation biology of parasites is an emerging and interdisciplinary field that recognizes the integral role parasites play in ecosystems. Parasites are intricately woven into the fabric of ecological communities, with diverse species occupying a range of ecological niches and displaying complex relationships with their hosts.

<i>Antheraea pernyi</i> Species of moth

Antheraea pernyi, the Chinese (oak) tussar moth, Chinese tasar moth or temperate tussar moth, is a large moth in the family Saturniidae. The species was first described by Félix Édouard Guérin-Méneville in 1855. Antheraea roylei is an extremely close relative, and the present species might actually have evolved from ancestral A. roylei by chromosome rearrangement.

<i>Antheraea paphia</i> Species of moth

Antheraea paphia, known as the South India small tussore, the tasar silkworm and vanya silkworm is a species of moth of the family Saturniidae found in India and Sri Lanka. The bulk of the literature on this species uses a junior synonym, Antheraea mylitta, rather than the correct name, A. paphia. It is one of a number of tasar silkworms, species that produce Tussar silk, a kind of wild silk that is made from the products of saturniid silkworms instead of the domesticated silkworm.
