A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies
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 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?
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.

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.
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.
Scientists have discovered a way of mimicking the stunningly bright and beautiful colors found on the wings of tropical butterflies.
A group of Japanese researchers have succeeded in building a fully functional replica model â€“ an ornithopter â€“ of a swallowtail butterfly, and they have filmed their model butterfly flying.
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.
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...
