Butterfly restrains Darwin
In experiments with butterflies, evolutionary biologists from Leiden University have demonstrated that natural selection is not always the only factor which determines the appearance of an organism. Constraints also appear to play a role at times in determining the progress and outcome of the evolutionary process. This research from Leiden... view more... (2002-10-24)
Radar tracking reveals that butterflies follow decisive flight paths
The charming meanderings of butterflies are not as random as they appear, according to new research. Scientists at Rothamsted Research, a research institute sponsored by the Biotechnology and Biological Sciences Research Council (BBSRC) in Hertfordshire, have found that their seemingly irresolute flutterings are in fact decisive flight paths. The... view more... (2005-04-05)
Climate warming and habitat loss threaten British Butterfly survival
Because butterflies are cold blooded, their growth and development are closely dependent on the weather and climate. When climates change insects can either shift breeding distributions to track it, stay put and adapt, or die out. Since the 1970s, climate warming in Britain has seen almost 20% of butterflies spread their ranges northwards,... view more... (2003-06-05)
Where Have All the Butterflies Gone?
Cold, wet conditions early in the year mean that 2006 is shaping up as the worst year for California's butterflies in almost four decades. view more (2006-05-09)
Expanding forests darken the outlook for butterflies, study shows
Changing environmental conditions in the Canadian Rockies are stifling the mating choices of butterflies in the region, say University of Alberta researchers. view more (2005-07-19)
Sexy or Repulsive? Butterfly Wings Can Be Both To Mates and Predators
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. view more (2009-04-02)
Anti-perfume - the male butterfly's gift to his partner
Pieris butterflies are not like all other butterflies. Both sexes agree about sex. In a dissertation about olfactory communication, Johan Andersson, a scientist at the Royal Institute of Technology in Stockholm (KTH), Sweden, presents exciting new findings about a joint effort that provides an alternative view of the theory of sexual selection.... view more...

Hind wings help butterflies make swift turns to evade predators, study finds
New tires allow race cars to take tight turns at high speeds. Hind wings give moths and butterflies similar advantages: They are not necessary for basic flight but help these creatures take tight turns to evade predators. view more (2009-01-09)
Smell-wars between butterflies and ants
Among humans, making yourself smell more alluring than you really are is a fairly harmless, socially accepted habit that maintains a complete perfume industry. view more (2008-01-04)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
Male-killing bacteria makes female butterflies more promiscuous
A study at UCL (University College London) finds that a high-prevalence of male-killing bacteria active in many species of insect including the butterfly, actually increases female promiscuity and male fatigue. view more (2007-02-06)
Butterflies lose body fat during metamorphosis
A group of scientists from Oregon have discovered that butterflies experience a great loss in body fat during metamorphosis. view more (2006-03-21)
Climate change isolates Rocky Mountain butterflies
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta. view more (2007-08-14)
Researchers find natural section favors parasite fitness over host health
Why do parasites harm their hosts? Classic evolutionary theory predicts that parasites become more virulent because they must transmit themselves between hosts, yet scientists have found little data to support this idea, until now. view more (2008-05-13)
Panama butterfly migrations linked to El Niño, climate change
A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film-but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. view more (2009-10-06)
Butterflies' wings dazzle with science
The brilliant dazzle of butterflies' wings could hold the key to a new type of optical material, called photonic crystals. Over the past 15 years, photonic crystals have attracted the attention of a vast international community, as scientists have begun to realise their potential applications in the field of optoelectronics and telecommunications.... view more...

Researcher discovers hybrid speciation in the Sierra Nevada
University of Nevada, Reno researcher Matthew Forister is among a group of scientists that have documented an unusual type of speciation in the Sierra Nevada, including a hybrid species of butterfly that can trace its lineage as far back as almost a half a million years ago. view more (2007-01-29)
Food for Flight: Monarch Butterfly Migration and Forest Restoration
USDA Forest Service (FS) research in the Ouachita Mountains of Arkansas suggests that decades of fire suppression have reduced the area's food supply for migrating monarch butterflies-and that restoration efforts that include prescribed burning can reverse this trend. view more (2006-11-20)
CU-Boulder Butterfly Payload to Launch Nov. 16 on Space Shuttle
When NASA's space shuttle Atlantis launches for the International Space Station on Nov. 16 it will carry a University of Colorado at Boulder butterfly experiment that will be monitored by thousands of K-12 students across the nation. view more (2009-11-11)
