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)
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)
New structure discovered in butterfly ears
A clever structure in the ear of a tropical butterfly that potentially makes it able to distinguish between high and low pitch sounds has been discovered by scientists from the University of Bristol. view more (2009-10-22)
Environmental effects on genetic adaptation and population dynamics
It seems intuitive that genes are affected by selection as a result of environment. In fact there is little evidence thus far that such genetic effects impact year-to-year population dynamics. view more (2006-04-25)
Highlights from Opto and Laser Europe, July 2000
Consultants and suppliers question train signal claims Claims made by the UK's rail operator Railtrack that its signal lights conform to the International Commission on Illumination's (CIE) recommendations have been questioned by its signal suppliers and external technical consultants. The allegations follow a story in last month's issue (OLE June... view more... (2000-06-23)
Moths cloaked in color
Travelers to the neotropics-the tropical lands of the Americas-might be forgiven for thinking that all of the colorful insects flittering over sunny puddles or among dense forest understory are butterflies. view more (2009-08-31)
Zoologists challenge longstanding theory that 'eyespots' mimic the eyes of predators' enemies
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. view more (2008-02-22)
Can moths or butterflies remember what they learned as caterpillars?
Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or memories formed at the larval or caterpillar stage... view more...

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 awesome and mysterious occurrence. view more (2008-01-09)
Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. view more (2005-12-06)
A question of height
Intelligent countryside management could improve the survival chances of animal and plant species threatened by climate change. view more (2009-07-06)
Researchers witness natural selection at work in dramatic comeback of male butterflies
An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back - genetically speaking - against a highly invasive, male-killing bacteria. view more (2007-07-13)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
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: Agricultural and Forest Entomology - The following... view more...

Global warming forces fish northwards
Fears that global warming is threatening British fish stocks were confirmed this week with the publication of a new study in the international journal Science. view more (2005-05-10)
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 species. view more (2005-02-08)
Why are there so many more species of insects? Because insects have been here longer
J. B. S. Haldane once famously quipped that "God is inordinately fond of beetles." Results of a study by Mark A. McPeek of Dartmouth College and Jonathan M. Brown of Grinnell College suggest that this fondness was expressed not by making so many, but rather by allowing them to persist for so long. view more (2007-04-04)
