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)

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... view more (2008-03-05)

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)

New study uncovers secrets behind butterfly wing patterns
The genes that make a fruit fly's eyes red also produce red wing patterns in the Heliconius butterfly found in South and Central America, finds a new study by a UC Irvine entomologist.   view more (2007-10-26)

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)

Children show goal-oriented behavior by age 3
Hang on, parents. After the terrible twos come the goal-oriented threes. Kids seem to grow into the ability to act in pursuit of goals outside of what they can immediately sense sometime around that age.   view more (2008-02-20)

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)

Leptin found to control appetite and limb development in frogs
Leptin, the hormone secreted by fat cells that plays an important role in food intake, has been described for the first time in a cold-blooded vertebrate, the South African clawed frog Xenopus.   view more (2006-06-13)

Hormone's role in insects could give insight for cancer treatment, malnutrition
Starvation typically has dire consequences for an organism's growth. In the tobacco hawkmoth, tissues starved during the last stage of larval development stop growing because they lack the proper nutrients.   view more (2006-06-02)

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)

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)

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)

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)

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)

Jekyll-Hyde neutron star discovered by researchers
Like something out of a Robert Louis Stevenson novel, researchers at NASA and McGill University discovered an otherwise normal pulsar which violently transformed itself temporarily into a magnetar, a stellar metamorphosis never observed before.   view more (2008-02-22)

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)

New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat.   view more (2006-04-26)

Finding out how the patterns of Nature develop
Researchers in the UK are developing new computer modelling techniques to show how intricate patterns in living organisms, such as those seen on the wing of a butterfly, might develop as the organism grows. The research could shed important new light on the fundamental biology of how patterns form... view more (2001-08-30)

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)

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... view more (2004-03-18)

Coating copies microscopic biological surfaces
Someday, your car might have the metallic finish of some insects or the deep black of a butterfly's wing, and the reflectors might be patterned on the nanostructure of a fly's eyes.   view more (2008-09-18)

Cheering News for Depressed Mussels
One of Britain's rarest animals could soon be enjoying a revival in the country's waterways, thanks to researchers at the University of Cambridge. Depressed River Mussel populations have suffered a 30 per cent drop in the last 100 years through pollution and modern dredging techniques, and the... view more (2001-06-19)

Press Invitation to the British Ecological Society`s Winter Meeting, University of York, 18-20 December 2002
You are invited to attend the UK's premier ecological event, the British Ecological Society's Winter Meeting, being held at the University of York on 18-20 December 2002. Thousands of ecologists from all four corners of the globe will be attending the meeting, which features more than 350... view more (2002-11-08)

Good housekeeping: why do shelter-dwelling caterpillars fling their frass?
Caterpillars of the silver-spotted skipper butterfly ballistically eject their individual fecal pellets (frass) as far as 40 body lengths away from their resting places in leaf shelters. Why do these and many other shelter-dwelling caterpillars go to such great lengths to distance themselves from... view more (2003-04-08)

Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama.   view more (2008-07-09)
