Colorful 'Eyespots' On The Wings Of Butterflies Add Detail To The Story Of Evolution

Oregon State University A new study of the colorful "eyespots" on the wings of some butterfly species is helping to address fundamental questions about evolution that are conceptually similar to the quandary Aristotle wrestled with about 330 B.C. – "which came first, the chicken or the egg?" After consideration, Aristotle decided that both the egg and the chicken had always existed. That was not the right answer. The new Oregon State University research is providing a little more...

Small prey fish can grow a bigger ‘eye’ on their rear fins as a way of distracting predators and dramatically boosting their chances of survival, new scientific research has found. Researchers from Australia’s ARC Centre of Excellence for Coral Reef Studies (CoECRS) have made a world-first discovery that, when constantly threatened with being eaten, small damsel fish not only grow a larger false ‘eye spot’ near their tail – but also reduce the size of their real eyes. The...

Male peacock tail plumage and courtship antics likely influence their success at attracting and mating with females, according to recent Queen's University research. Roz Dakin and Robert Montgomerie have found that natural variation in the number of eyespots on a peacock's tail does not impact a male's mating success. However, peacocks whose tails are clipped to considerably reduce the number of eyespots are less successful at mating. Female rejection of males with substantially fewer...

Yale University biologists say they've determined butterflies seem able to both attract mates and ward off predators by using different sides of their wings. You want to be noticeable and desirable for mates, but other onlookers, including predators, are paying attention to those signals as well, said Jeffrey Oliver, a Yale postdoctoral researcher. Oliver was interested in whether the eyespots on the upper side of butterflies' wings serve a different purpose than the ones on the underside....

Butterflies seem able to both attract mates and ward off predators using different sides of their wings, according to new research by Yale University biologists. Trying to find the balance between these two crucial behaviors is one of nature's oldest dilemmas, according to Jeffrey Oliver, a postdoctoral associate in Yale's Department of Ecology and Evolutionary Biology and lead author on the study, which appears online today in the journal Proceedings of the Royal Society B: Biological...

Circular markings on creatures such as butterflies are effective against predators because they are conspicuous features, not because they mimic the eyes of the predators' own enemies, according to research published today in the journal, Behavioral Ecology[1]. Zoologists based at the University of Cambridge challenge the 150-year-old theory about why these markings are effective against predators. Many animals possess protective markings to avoid predation, including patterns to reduce the...

The Painted Lady (Vanessa cardui) is a well-known colorful butterfly, known in North America as the Cosmopolite. It is one of the most widespread of all butterflies, found on every continent except Australia which has a close relative, the Australian Painted Lady (Vanessa kershawi, sometimes considered a subspecies). Other closely related species are the American Painted Lady (Vanessa virginiensis), and the West Coast Lady (Vanessa anabella). The Painted Lady occurs in any temperate...
