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....

Scientists studied the defences used by caterpillars that transform into large white butterflies, called Pieris brassicae. The insects regurgitate semi-digested cabbage leaves to make them smell and taste unpleasant to predators. The team found, however, that frequent use of this defence reduces the caterpillars' growth rate and the number of eggs they produce. It remains unclear why their defences affect them in this way, but the loss of nutrition from frequent regurgitation is thought to...

A new study published Thursday in the journal Science has found that female butterflies that grow up in colder temperatures become more aggressive as adults, actively chasing males for sex and food. "Behavior in these butterflies is changed by the temperatures experienced during development," said study co-author Kathleen Prudic of Yale University, who studied female Squinting Bush Brown Butterflies (Bicyclus anynana). Researchers were curious as to why some females had ornate wing markings...

By Daniel Stolte, University of Arizona A newly identified relationship between a fly and a weedy mustard-type plant promises to answer many long-standing questions surrounding the evolutionary arms race between plant-eating insects and their host plants Scientists trying to get a grip on the arms race between plant-eating insects and the defenses put up by their hosts just got a boost from new research by a University of Arizona entomologist published in the early view edition of Molecular...

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...

Research suggests coping with global warming has a genetic component With global warming and climate change making headlines nearly every day, it could be reassuring to know that some creatures might cope by gradually moving to new areas as their current ones become less hospitable. Nevertheless, natural relocation of species is not something that can be taken for granted, according to Jessica Hellmann, Associate Professor at the University of Notre Dame Department of Biological Science in...

Scientists have discovered a way of mimicking the stunningly bright and beautiful colors found on the wings of tropical butterflies. The findings could have important applications in the security printing industry, helping to make bank notes and credit cards harder to forge. The striking iridescent colors displayed on beetles, butterflies and other insects have long fascinated both physicists and biologists, but mimicking nature's most colorful, eye-catching surfaces has proved elusive. This...

A group of Japanese researchers, who publish their findings today Thursday, 20 May in IOP Publishing's Bioinspiration & Biomimetics, have succeeded in building a fully functional replica model "“ an ornithopter "“ of a swallowtail butterfly, and they have filmed their model butterfly flying. Among the various types of butterflies, swallowtails are unique in that their wing area is very large relative to their body mass. This combined with their overlapping fore wings means...

The Cairns Birdwing (Ornithoptera euphorion), is Australia's largest native butterfly species. Cairns Birdwings are found southwards from Mount Webb and Cooktown to Mackay in Queensland. Favored habitat is primary rainforest, although the species will breed readily in a home garden if the correct larval host plants are grown. Males have a predominately black upper wing with emerald green flashes, however the female lacks the green coloring, having a plain black upper wing with white...

Queen Alexandra's Birdwing (Ornithoptera alexandrae), is the largest butterfly in the world. The species was named by Lord Walter Rothschild in 1907, in honor of Queen Alexandra, wife of King Edward VII of the United Kingdom. The first European to discover the species was Albert Stewart Meek in 1906, a collector employed by Lord Walter Rothschild to collect natural history specimens from Papua New Guinea. Although the first specimen was taken with the aid of a small shotgun, Meek soon...

The Anise Swallowtail (Papilio zelicaon) is a common swallowtail butterfly found in western North America. Both the upper and lower sides of its wings are black, but the upper wing has a broad yellow stripe across it, which gives the butterfly an overall yellow appearance. Striking blue spots adorn the rear edge of the rear wing, and the characteristic tails of the swallowtails. Its wingspan is 7-9 cm and its body is somewhat shorter than the rather similar Western Tiger Swallowtail, with...
