In late August 2014, the Xerces Society, Center for Food Safety, Center for Biological Diversity and Dr. Lincoln Brower submitted a petition to the Secretary of the Interior requesting the Monarch butterfly be listed as “threatened” under the Endangered Species Act. Micro RNAs regulate gene expression, and each miRNA can regulate several proteins. Butterfly monarch of the genus danaid, which belongs to the family of nymphalids. Pages 33-44. SW 155. Science 161: 1349-1350. Invertebrate predators such as ants, spiders, and wasps attack monarch larvae on milkweed plants. Nature 350: 497-498. Courtship behavior of monarchs has been described in detail and consists of a mating ritual, where male grasps the female in the air and brings her down to the ground, where mating occurs. It allowed scientists to determine the migration path of monarchs. Resistance to mating by female monarch butterflies. Figure 15. Being distasteful due to ingestion by larvae and sequestration by adults of cardenolides that are toxic to birds, monarch serves as a model for several mimetic species and is frequently confused with the viceroy (Limenitis archippus (Cramer, 1776)) and queen (Danaus gilippus (Cramer, 1775)) butterflies. The Wanderer or Monarch Butterfly is well-known in North America for its massive and wide-ranging migrations. 1999a. Link to video of caterpillar creating chrysalis. The vicinity of overwintering sites in the Mexican Transvolcanic Range contains high level of magnetic anomalies, which probably helps monarchs to find them. Photograph by Andrei Sourakov, Florida Museum of Natural History. The last Pleistocene glaciations in North America instigated migration to Mexico in the east and to Californian coast and deserts in the west. Birds such as black-beaked orioles and black-headed grosbeaks attack monarchs at their overwintering sites. Recent analysis of genomes of migratory and non-migratory monarchs shows that monarchs originated in North America from a migratory ancestor. Adult monarch butterflies, Danaus plexippus Linnaeus, migrating at their Mexican overwintering site in Sierra Madre, Michoacán, Mexico. 2008). Adult monarchs, Danaus plexippus Linnaeus, from Gainesville, Florida. Figure 26. 1999b. Experiments conducted with captive blue jays showed that monarchs indeed are toxic (Brower et al. The pupa (chrysalis) is formed by the larva hanging on a substrate, such as underside of leaves and twigs, usually away from the host plant. 3. White swamp milkweed, Asclepias perennis Walter (Apocynaceae), a host of the monarch butterfly, Danaus plexippus Linnaeus. The margins, or outer edges, of the wings are also dotted with white spots. However, though mortality due to ingestion of corn pollen does occur, it has been shown that its effect on Monarch population might not be as dramatic as was initially thought (Auman-Bauer 2001). The monarch has similar coloration to, and is frequently mistaken for, the viceroy butterfly. Monarchs are not endangered as a species due to many sedentary populations in the south of its range. The scientific name of the monarch butterfly is Danaus plexippus. Figure 24. CD-ROM. Although it has six legs like all in the insect family, only the middle legs are put to use. You can read more about it here. Brower LP. London: British Museum (Natural History). The western population overwinters along the California coast and breeds in areas west of the Rockies. Butterflies 1: Butterflies of the Southeast. The second version of the name gave the butterfly Samuel Skudder in 1874, relying on its large view and capture of vast territories for living. However, the deforestation around their overwintering sites in Mexico puts the northeastern population of monarch and the remarkable phenomenon of migration in danger. Reppert SM. Mating attempts frequently fail due to resisting by females (e.g., Frey, 1997). Figure 28.

Brower LP. The female monarch butterfly lays each of her eggs individually on the leaf of a milkweed plant, attaching it with a bit of glue she secretes. The large and brilliantly-colored monarch butterfly is among the most easily recognizable of the butterfly species that call North America home. Apparently, there are costs and benefits to the ingestion of glycosides, since it was shown that monarch females prefer plants with intermediate cardenolide level, rejecting higher and lower level-containing plants (Oyeyele and Zalucki, 2008). The monarch is the only species of this group, that contains 300 species world-wide, to occur in Canada. Tagged adult monarch, Danaus plexippus Linnaeus, Gainesville, Florida, released during the Butterfly Festival, October 2007.

FAQs on the Monarch Butterfly Endangered Species Act Petition. There are three species of Monarch Butterflies. Figure 17. The name evokes the species' ability to hibernate and metamorphize. At the overwintering sites in Mexico, the monarchs spend over four months in a reproductive diapause. Brower LP. Neuron 46: 457-467. The monarch butterfly is an insect (Class: Insecta), belonging to the subgroup of insects that includes the butterflies, moths and skippers (Order: Lepidoptera; from the Greek, "Lepis" = scale, "pteron" = wing). Photograph by Andrei Sourakov, Florida Museum of Natural History. By some estimates, the population of this increasingly elusive pollinator has plunged to a mere 1% of its historic levels. Scientific name: Danaus plexippus. In monarchs, one of the cryptochromes functions as a likely circadian photoreceptor, while another appears to function as the major transcriptional repressor of the clockwork transcriptional feedback loop. Scientific Name: Danaus plexippus. The monarchs, Danaus plexippus Linnaeus, are among the best known of the world's butterflies, due to their remarkable ability to migrate, wide distribution, and charismatic appearance. Credit for this name goes to Carolus Linnaeus, who invented our modern system for scientific names. These two bird account for over 60% of the total monarch mortality. Photograph by Andrei Sourakov, Florida Museum of Natural History. 2003. Danaus refers to a genus of butterflies and plexippus refers to the specific Monarch Butterfly species.

Quantitative changes in forest quality in a principal overwintering area of the monarch butterfly in Mexico, 1971-1999. They may be involved in initiating/mediating the migratory state in monarch butterflies. A few years ago, the controversy over the influence of Bt corn on Monarch mortality arose. Danaus plexippus population growth rate and (c) environmental stochasticity (i.e., squared deviations of annual growth rates from average growth rate). Cold Spring Harbor Symposia on Quantitative Biology 72: 113-118. While the Xerces Society engages in monarch conservation efforts across North America, partnering with leaders in the U.S., Mexico, and Canada - a significant amount of our work focuses on monarch populations in western states, where overwintering populations have declined by 97% since the 1980s. The monarch butterfly is a member of the milkweed butterfly group. Monarchs are great model organisms for researching many general questions about animals in general. Soon thereafter, Xerces launched the Monarch Project as a medium of partnership with Mexican and Californian conservation groups, agencies, and individuals on behalf of monarchs and their habitat. 1999c. Que Pasa (Toronto) 3: 9-11. (Information for this species page was gathered in part by Ray Zerjav for Biology 220W in Spring 2011 at Penn State New Kensington) The monarch butterfly ( Danaus plexippus) is quite possibly the most widely recognized and widely admired insect in the United States. Several entomopathogenic organisms can infect monarchs, including a nuclear polyhedrosis virus and Pseudomonas bacteria, protozoan parasites such as Ophryocystis elektroscirrha, and a microsporidian Nosema species (McLaughlin and Myers 2007).

One of the features of insects, intolerance of the cold season, and the food consumed does not grow during the winter in the native regions of existence. The ability to navigate to the overwintering sites is genetic and is linked to time-compensated sun compass orientation. Figure 2. Milkweed Butterflies, their Cladistics and Biology.
