1-800-344-WILD. While the striking colouration of the upperwings serves as a visual warning to predators that this species is poisonous (5), the undersurface of the wings is duller orange, and helps to camouflage this species against tree bark and other substrates when at rest (4). Cultivated alfalfa, clover, and sunflower also are important resources in Texas. In this mini-review article, I begin by describing how studies on monarch migration can provide us with generalizable information on how sensory cues can mediate key aspects of animal movement. Photo by markjohnrichards (CC BY-SA 2.0). The two best-known populations are the North American western and eastern migratory populations, which travel vast distances between British Colombia and California, and from Southern Canada, through the eastern United States to central Mexico. Female monarch butterflies lay eggs, usually singly, on a variety of milkweed species, sticking them to the underside of the leaves (2). Commission for Environmental Cooperation, Montreal. Wiley-Blackwell, New York. Adults in the migratory (overwintering) generation may live up to nine months, but do not mate and lay eggs until the following spring. The caterpillar then forms a chrysalis in which metamorphosis take place over a period of 9 to 15 days (6). According to the Center for Biological Diversity the North American population of Danaus plexippus has declined by 80% during the past two decades. Burnie, D. (2001) Animal. Habitat Milkweeds (numerous species) are the sole food plant for Monarch caterpillars. State: Special Concern . Invertebrates - Animals with no backbone. ... As the world warms, suitable habitat will begin to move northward resulting in a longer migration. Habitat and Distribution. Danaus chrysippus, also known as the plain tiger, African queen, or African Monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. Various governmental and non-governmental organisations, such as The Xerces Society, are currently working to achieve these goals. As monarch caterpillar grows they shed (molt) their skin five times and often eat it before eating more milkweed! When most people hear “butterfly,” images of the beloved orange-and-black monarch (Danaus plexippus) spring to mind.But that iconic fluttering insect has a problem: Its overwintering numbers have plummeted since the 1990s—a situation so serious that the U.S. Monarchs fly from sea level up to 2,500 meters. for breeding. Monarchs at overnight roosting site during migration (Jessica Boiser/USFWS CC BY 2.0). The monarch butterfly has yet to be assessed by the IUCN. Monarchy Rising by Jay Burney The Story of the Monarch Butterfly is historical, iconic, and for a while now, sadly typical of the decline of nature, pollinators, and the condition of the natural world. The adult monarch butterfly is brightly coloured, with orange upperwings, interlaced with black veins and surrounded by a wide, black border marked with numerous white spots (2) (4). They migrate to overwintering sites within 2.4 km of the California coast between Mendocino County and Baja, from September to November. In the western population, roosting generally occurs in both native and nonnative deciduous and evergreen trees.

As agricultural practices intensify, species once common in agricultural landscapes are declining in abundance. Migrating generations, which emerge in late summer and fall, live 8 – 9 months. Monarchs have four to five reproductive generations per year. Essential to the conservation of migratory species is understanding the full life-cycle ecology of populations across geographically disparate seasonal ranges (Webster et al., 2012; Small-Lorenz et al., 2013; Flockhart et al., 2015). (2008) North American Monarch Conservation Plan. Expansive range extends through much of North, Central and South America. The eastern population migration commences at the summer breeding grounds, which range as far north as southern Canada. USFWS Customer Service Center Danaus plexippus is found throughout the Americas and Australia, with individuals reported in New Guinea and Western Europe. They grow, shedding their skin to get bigger. The monarch butterfly can be found in a variety of temperate and tropical open habitats. More than 45 transportation and energy companies, as well as dozens of private landowners, have agreed to create or maintain monarch butterfly (Danaus plexippus) habitat along “ rights-of-way ” corridors across the United States. Lists of preferred nectar plants by region specific to monarchs can be found at http://www.xerces.org/monarch-nectar-plants/. ), gayfeathers (Liatris spp. EL Education Announces Second Edition Of Acclaimed 6-8 ELA Curriculum, UNEP World Conservation Monitoring Centre, https://xerces.org/california-monarch-campaign/, http://www3.cec.org/islandora/en/item/2350-north-american-monarch-conservation-plan-en.pdf, www.worldwildlife.org/species/finder/monarchbutterflies/monarchbutterflies.html, https://www.butterfliesandmoths.org/species/Danaus-plexippus. Several subspecies, such as M. p. megalippe (Mexico, southern U.S.) and M. p. menippe(South America) have been described. The monarch butterfly (Danaus plexippus plexippus) is a large butterfly that lives in a variety of habitats throughout North America and various additional locations across the globe. Monarch butterflies (Danaus plexippus) range throughout the world, but this assessment focuses on North American populations.Monarchs have a high dispersal ability across a large geographic range. In addition, vagrant individuals have been reported in western Europe as far north as the British Isles. Their work will help to ensure that this spectacular butterfly is preserved and that its extraordinary migratory journey will be witnessed by future generations (4)(8). The awe-inspiring annual migration of monarch butterflies (Danaus plexippus) is an iconic example of long-distance migratory phenomena in which environmental sensory cues help drive successful migration. Adults in the summer generations live two to five weeks, mating when three to eight days old. Monarchs can be found between southern Canada and norther South America. One of the best-known butterfly species, the beautiful monarch butterfly (Danaus plexippus) is renowned for its spectacular, long-distance annual migrations .The adult monarch butterfly is brightly coloured, with orange upperwings, interlaced with black veins and surrounded by a wide, black border marked with numerous white spots . Adults use a wide variety of flowering plants throughout migration and breeding. After four days, the caterpillar hatches, and eats almost constantly, increasing in mass by almost 2,000 times over a 9 to 14 day period, before undergoing metamorphosis. Here they form some of the largest single species aggregations known, numbering millions of individuals, which blanket the trees on which they roost (2)(6). Two migratory populations of monarchs occur in North America (Urquhart and Urquhart, 1977). In addition, outside the wintering sites monarch butterflies are further affected by the use of pesticides, habitat loss, the loss of milkweed populations, parasites, and climate change (4). In 2008, the Commission for Environmental Cooperation created The North American Monarch Conservation Plan, which details a strategy for conserving and maintaining the Monarch butterfly population through international cooperation between Canada, The United States and Mexico. Like the adult, the fully-grown monarch butterfly caterpillar is also highly distinctive, possessing bold, yellow, black and white bands over the entire five centimetre-long body, with a pair of long black filaments near the head and a pair of shorter filaments towards the rear (6)(7). Sedentary populations that are found in Mexico, Central and South America (including the Caribbean islands) are somewhat different from migratory populations of D. p. plexippus found in North America. The Monarch (Danaus plexippus) adult is a large, showy butterfly with a wingspan of 7-11 cm. (1992) The Butterflies of North America: A Natural History and Field Guide. The plan’s aims include the decrease or elimination of deforestation at the wintering grounds; addressing habitat loss and fragmentation along the migratory route and at the breeding grounds; public education about the threats faced by this species; and increased monitoring during migrations (4).
