The mystery of how a butterfly has changed its wing patterns to mimic neighboring species and avoid being eaten by birds has been solved by a team of European scientists. The study was published August 14, 2011 in the journal Nature. The greatest evolutionary thinkers, including Wallace, Bates and Darwin, have all wondered how butterflies that taste bad to birds have evolved the same patterns of warning coloration. Now for the first time, researchers led by the CNRS (Mus©um National...

Mothers have a stronger tendency to mimic their daughters' consumption behavior than vice versa How much do our children influence our consumption behavior? Much more than we thought. A new study by a Temple University Fox School of Business professor finds that teenage girls have a strong influence on the products their mothers buy solely for personal use, as in makeup or clothing, and that mothers have a much stronger tendency to mimic their daughters' consumption behavior than vice versa....

Red may mean STOP or I LOVE YOU! A red splash on a toxic butterfly's wing screams DON'T EAT ME! In nature, one toxic butterfly species may mimic the wing pattern of another toxic species in the area. By using the same signal, they send a stronger message: DON'T EAT US! Now several research teams that include Smithsonian scientists in Panama, have discovered that Heliconius butterflies mimic each other's red wing patterns through changes in the same gene. Not only does this gene lead to the...

Researchers find single gene controls mimicry across different species For 150 years scientists have been trying to explain convergent evolution. One of the best-known examples of this is how poisonous butterflies from different species evolve to mimic each other's color patterns "“ in effect joining forces to warn predators, "Don't eat us," while spreading the cost of this lesson. Now an international team of researchers led by Robert Reed, UC Irvine assistant professor of ecology...

"Money, money, money Must be funny Money, money, money Always sunny In the rich man's world." -ABBA, 1976 We rely on money in our day-to-day life and it is constantly in our minds. After all, money makes the world go round, doesn't it? Now, a new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, tries to better understand the psychological effect of money and how it affects our behavior, feelings and...

New research reveals how biological arms races between cuckoos and host birds can escalate into a competition between the host evolving new, unique egg patterns (or 'signatures') and the parasite new forgeries. Brood parasitic birds such as cuckoos lay eggs that mimic those of their hosts in an effort to trick them into accepting the alien egg and raising the cuckoo chick as one of their own. New research from the University of Cambridge has found that different bird species parasitized by...

Caterpillars that masquerade as twigs to avoid becoming a bird's dinner are actually using clever behavioral strategies to outwit their predators, according to a new study.Researchers at the universities of Exeter, Liverpool, Liverpool Hope and Glasgow have shown that when it comes to the art of camouflage, things are never quite the way they seem.The study, published online today in the journal PNAS, reveals that twig-mimicking caterpillars choose their location to maximize their chances of...

Sex and violence, or at least death, are the key to reproduction for the orchid Satyrium pumilum. Research led by Timothes van der Niet at the University of KwaZulu-Natal shows that the orchid lures flies into its flowers by mimicking the smell of rotting flesh. A new study comparing the scent of the orchids with that of roadkill is to be published in the Annals of Botany http://dx.doi.org10.1093/aob/mcr048 . The orchid S. pumilum is found in sandy, moist conditions near small streams across...

When prowling for a hook up, it's not always the good-looker who gets the girl. In fact, in a certain species of South American fish, brawn and stealth beat out colorful and refined almost every time. In a series of published studies of a South American species of fish (Poecilia parae), which are closely related to guppies, Syracuse University scientists have discovered how the interplay between male mating strategies and predator behavior has helped preserve the population's distinctive...

Stretched tube designed by harvard researchers mimics zebra finch songs For centuries, hunters have imitated their avian prey by whistling through their fingers or by carving wooden bird calls. Now a team of physicists at Harvard University in Cambridge, Massachusetts, has reproduced many of the characteristics of real bird song with a simple physical model made of a rubber tube. "We wanted to know if you [could] build a simple device, which has minimal control but reproduces some non-trivial...

Flower-flies (also known as hover-flies) are a family of flies (Diptera), with the scientific name of "Syrphidae". As their names suggests, they are most often seen around flowers. The adults feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In certain species, the larvae are saprophytes, eating decaying plant and animal matter in the soil or in ponds and streams. In others, the larvae are insectivores and prey on aphids, thrips, and other...

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...
