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)

In the migratory marathon, parasitized monarchs drop out early
A little-studied outcome of animal migration is whether these long journeys can limit the spread of parasites by weeding out diseased animals. Monarch butterflies in eastern North America fly up to thousands of kilometers from Canada to Central Mexico - one of the longest migrations of any insect... view more (2005-02-08)

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)

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)

Scientists unravel the molecular basis of monarch butterfly migration
Since its discovery, the annual migration of eastern North American monarch butterfly has captivated the human imagination and spirit. That millions of butterflies annually fly up to 2000 miles to reach a cluster of pine groves in central Mexico comprising just 70 square miles is for many an... view more (2008-01-09)

Monarch butterflies help explain why parasites harm hosts
It's a paradox that has confounded evolutionary biologists since Charles Darwin published On the Origin of Species in 1859: Since parasites depend on their hosts for survival, why do they harm them?   view more (2008-05-15)

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... 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... 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... 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)

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... view more (2004-02-23)

Royal Entomological Society Awards For The Best Entomological Publications
The Royal Entomological Society have established a series of awards for the best papers published in their six scientific journals over the preceding two years. The winners are decided by the Editors and Editorial Board of each of three journals each year. This year the journals selected are:... view more (2002-06-20)

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)

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)

WFU study finds that moths mimic sounds to survive
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study.   view more (2007-05-31)

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... view more (2004-11-04)

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)

Have traits, will travel: Some butterflies travel farther, reproduce faster
Researchers have uncovered physiological differences among female Glanville fritillary butterflies that allows some to move away from their birth place and establish new colonies.   view more (2006-10-11)

War between the sexes influences evolution in some species, say scientists
Competition and conflict between males and females start inside the egg in some species, say scientists.   view more (2006-04-07)

Female Butterflies Go for Sparkle - Not Size - When Choosing to Mate
Size doesn't matter, at least not the size of the eyespots on a male butterfly's wings when female butterflies consider potential mates.   view more (2005-06-29)

Butterfly speciation event recreated
In a matter of months, butterflies sporting the yellow and red wing color pattern of a wild species were created through simple laboratory crosses of two other wild species, researchers report in the June 15, 2006 edition of the journal Nature.   view more (2006-06-15)
