A Single Gene Controls Wing Mimicry In Butterflies
2014-03-05 14:04:36

University of Chicago A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists from the University of Chicago, March 5 in Nature. Surprisingly, the gene described, doublesex, is already well-known for its critical role in sexual differentiation in insects. "Conventional wisdom says that it should be multiple genes working together to control the whole wing pattern of a butterfly," said Marcus Kronforst,...

Butterfly Wings Serve As Inspiration For Materials That Could Change Color By Design
2013-07-18 05:55:35

April Flowers for redOrbit.com - Your Universe Online Butterflies have beautiful wings full of colorful patterns that do remarkable things with light. A new study from a Hong Kong Baptist University team of physicists has uncovered how subtle differences in tiny crystals of butterfly wings create stunningly varied patterns of color, even among closely related species. If the team can figure out how to replicate the wings' light-manipulating properties, the discovery could lead to new...

Wing Bling: Flashier Is Better For Female Butterflies
2012-06-11 14:21:23

If female butterflies are programmed to identify males of their species by the patterns of spots on their wings, how can new wing patterns evolve in males? The answer is that while females are predisposed to prefer a specific pattern, they learn to like flashier ones more, according to a new Yale University study. The study published online the week of June 11 in the Proceedings of the National Academy of Sciences gives a partial explanation of an evolutionary mystery. Biologists...

According to a new study published in the Journal of Economic Entomology (http://bit.ly/AlYBUM) by University of Florida researchers, a key amino acid essential for human nutrition is also an effective insecticide against caterpillars that threaten the citrus industry. The Lime Swallowtail, or Citrus Swallowtail, is a well-known agricultural pest from southern Asia discovered in the Caribbean in 2006, and researchers say its potential impact on the U.S. citrus industry is cause for serious...

Appalachian Tiger Swallowtail Butterfly Is A Hybrid
2011-09-09 09:59:31

  Flitting among the cool slopes of the Appalachian Mountains is a tiger swallowtail butterfly species that evolved when two other species of swallowtails hybridized long ago, a rarity in the animal world, biologists from The University of Texas at Austin and Harvard University have found. They discovered that the Appalachian tiger swallowtail, Papilio appalachiensis, evolved from mixing between the Eastern tiger swallowtail, P. glaucus, and the Canadian tiger swallowtail, P....

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...

If it were up to Jessica Hellmann, insects such as butterflies and beetles would wield just as much conservation clout as traditional conservation icons, such as polar bears, tigers and dolphins.Why?"Animals such as polar bears, tigers and dolphins are tremendously important, but mostly because they help define how we think about our relationship with the natural world," says Hellmann. "But when it comes to the functioning of ecosystems, insects are where it's at."Why are insects so...

The Western Tiger Swallowtail (Papilio rutulus), is a common Swallowtail Butterfly of western North America, and is frequently seen in urban parks and gardens as well as in rural woodlands and riparian areas. The normal range of the Western Tiger Swallowtail covers much of western North America, from British Columbia to North Dakota in the north to Baja California and New Mexico in the south. Individuals occasionally turn up east of this range. It is a large, brightly colored and active...

The Eastern Tiger Swallowtail (Papilio glaucus), is species of swallowtail butterfly. It is found in the Eastern United States, as far north as southern Vermont, and as far west as extreme Eastern Colorado. It flies from spring through fall, and most of the year in the southern portions of its range, where it may produce two or three broods a year. Adult males are yellow, with four black "tiger stripes" on each fore wing. The trailing edges of the fore and hind wings are black which is...

The Black Swallowtail (Papilio polyxenes), is a butterfly found throughout much of North America. It has a wingspan of 3.25 to 4.25 inches. The upper surface of the wings is mostly black. On the inner edge of hind wing is a black spot centered in larger orange spot. A male of this species has a yellow band near the edge of the wings. The female has a row of yellow spots. The hind wing of the female has an iridescent blue band. In the Southwest USA, yellow forms predominate in the subspecies....

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...

The Common Blue (Polyommatus icarus) is a small butterfly in the family Lycaenidae common throughout Europe. It is often found in meadows or open, hilly areas. Its wingspan is 3 to 3.5 cm. The wings or the male are iridescent blue with a white fringe. The female is usually brown with orange spots on the outer edges of the wing. In some areas the females have a blue coloration to the wings. The undersides of both sexes have a pattern of white, black and orange spots. The caterpillar is...
