Experts report a partial recovery in the annual winter migration of Monarch butterflies to Mexico, following a devastating 75 percent fall last year. The conservation group World Wildlife Fund Mexico says the butterflies from the U.S. and Canada are covering an area of forests that is double that of last year, when their numbers dropped to a historic low. "Fluctuations in insect populations are normal in nature," the study's sponsors said in a statement, quoted by the Associated Press....

It's a common assumption that animal migration, like human travel across the globe, can transport pathogens long distances, in some cases increasing disease risks to humans. West Nile Virus, for example, spread rapidly along the East coast of the U.S., most likely due to the movements of migratory birds. But in a paper just published in the journal Science, researchers in the University of Georgia Odum School of Ecology report that in some cases, animal migrations could actually help reduce...

Monarch butterflies appear to use medicinal plants to treat their offspring for disease, research by biologists at Emory University shows. Their findings were published online Oct. 6 in the journal Ecology Letters. "We have shown that some species of milkweed, the larva's food plants, can reduce parasite infection in the monarchs," says Jaap de Roode, the evolutionary biologist who led the study. "And we have also found that infected female butterflies prefer to lay their eggs on plants that...

Conservation groups said on Monday that monarch butterflies are facing a new threat from severe storms that have devastated some sanctuary forests in Mexico. The Nature Conservancy said during a news conference that storm damage in Mexico's 32,124-acre monarch reserve has presented another blow to the butterflies, which arrived in Mexico in record low numbers last season after a 2,000-mile journey from Canada. Omar Vidal, head of World Wildlife Fund Mexico said that 289 acres were damaged...

Monarch butterflies "” renowned for their lengthy annual migration to and from Mexico "” complete an even more spectacular journey home than previously thought. New research from the University of Guelph reveals that some North American monarchs born in the Midwest and Great Lakes fly directly east over the Appalachians and settle along the eastern seaboard. Previously, scientists believed that the majority of monarchs migrated north directly from the Gulf coast. The study appears...

Forget top-to-bottom only. New Cornell University evolutionary biology research shows how plants at the bottom of the food chain have evolved mechanisms that influence ecosystem dynamics as well. (Science, March 26, 2010.) "The ecology and interactions of most organisms is dictated by their evolutionary history," said Anurag Agrawal, associate professor of ecology and evolutionary biology (EEB), the study's senior author. In food webs, predators help suppress populations of prey by eating...

Traveling long distances spurs the evolution of larger and pointier wings A University of Georgia study has found that monarch butterflies that migrate long distances have evolved significantly larger and more elongated wings than their stationary cousins, differences that are consistent with traits known to enhance flight ability in other migratory species. As part of a National Science Foundation and UGA-funded study, researchers in the Warnell School of Forestry and Natural Resources and...

UMass Medical School neurobiologists use transgenic fruit flies and monarch butterfly transgenes to help define magnetoreception mechanism Building on prior investigation into the biological mechanisms through which monarch butterflies are able to migrate up to 2,000 miles from eastern North America to a particular forest in Mexico each year, neurobiologists at the University of Massachusetts Medical School (UMMS) have linked two related photoreceptor proteins found in butterflies to animal...

The Monarch butterfly (Danaus plexippus) is a well-known North American butterfly with easily identifiable orange and black wings. The females have darker veins on their wings, and the males have a spot in the center of each hindwing from which pheromones are released. Monarchs are especially noted for their lengthy annual migration. They make massive southward migrations from August through October. A northward migration takes place in the spring. During these migrations the females...

A butterfly is a flying insect of the order Lepidoptera belonging to one of the superfamilies Hesperioidea (the skippers) and Papilionoidea (all other butterflies). Many butterflies have remarkable colors and patterns on their wings. People who study or collect butterflies (or the closely related moths) are called lepidopterists. Butterfly watching is growing in popularity as a hobby. The four stages in the lifecycle of a butterfly Unlike many insects, butterflies do not experience a...
