Fire ant-attacking fly spreading rapidly in Texas
Parasitic flies introduced to control red imported fire ants have spread over four million acres in central and southeast Texas since the flies' introduction in 1999. view more (2006-09-27)
Temporary infidelity may contribute to the stability of ancient relationships
Fungus-farming ants have cultivated the same fungal crops for 50 million years. Each young ant queen carries a bit of fungus garden with her when she flies away to mate and establish a new nest. view more (2009-06-02)
Monocolonialism holds clues for understanding the little fire ant
The presence of Wasmannia auropunctata in New Caledonia was first recorded in 1972. This small ant, with workers measuring only 1 or 2 mm, originates from tropical America. It was introduced by human activity, accidentally brought in, probably on plant material imported for use in forestry. The ant has colonized almost every ecological type of... view more...

The high cost of living with ants
A new sexually transmitted disease has been found in British ladybirds, ecologists have discovered, and it is their close association with wood ants that is to blame. Speaking at the British Ecological Society's Winter Meeting, being held at the University of York on 18-20 December 2002, Dr John Sloggett of the University of Bayreuth in Germany... view more...

Ants show us how to make super-highways
Certain army ants in the rainforests of Central and South America conduct spectacular predatory raids containing up to 200,000 foraging ants. view more (2007-05-29)
Parasite causes zombie ants to die in an ideal spot
A study in the September issue of The American Naturalist describes new details about a fungal parasite that coerces ants into dying in just the right spot-one that is ideal for the fungus to grow and reproduce. view more (2009-08-12)
Worker ants of the world, unite! You have nothing to lose but your fertility
The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, Charles Darwin had an idea and now he's been proven right. view more (2008-11-20)
Worker ants store fat to share with colony members during times of need
In a fascinating new study from the September/October 2006 issue of Physiological and Biochemical Zoology, Daniel A. Hahn (University of Florida) explores the ability of ants to store excess fat and pass it to colony members through lipid-rich oral secretions or unfertilized eggs. view more (2006-07-27)
Ants vs. worms: Computer security mimics nature
In the never-ending battle to protect computer networks from intruders, security experts are deploying a new defense modeled after one of nature's hardiest creatures - the ant. view more (2009-09-28)
When ants attack: Researchers recreate chemicals that trigger aggression in Argentine ants
Experiments led by researchers at the University of California, Berkeley, have demonstrated that normally friendly ants can turn against each other by exploiting the chemical cues they use to distinguish colony-mates from rivals. view more (2009-10-28)
Flexible genes allow ants to change destiny
The discovery of a flexible genetic coding in leaf-cutting ants sheds new light on how one of nature's ultimate self-organising species breeds optimum numbers of each worker type to ensure the smooth running of the colony. view more (2007-05-25)
Key to the success of invasive ants discovered
An international team of researchers, with the participation of Universitat Autònoma de Barcelona and CREAF, has achieved to resolve fundamental questions related to the behaviour of ants. view more (2009-01-22)
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)
Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. view more (2006-12-05)
First 'mainly vegetarian' spider described
The 40,000 or so spiders that have been described are generally known as strict predators, trapping their prey in elaborate webs or hunting them down directly. view more (2009-10-13)
Ants and avalanches: Insects on coffee plants follow widespread natural tendency
Ever since a forward-thinking trio of physicists identified the phenomenon known as self-organized criticality---a mechanism by which complexity arises in nature---scientists have been applying its concepts to everything from economics to avalanches. view more (2008-01-24)
Study suggests past climate changes may have promoted the formation of new species in the Amazon
The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America. view more (2008-07-23)
Ants more rational than humans
In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our - multimodal, egg-headed, tool-using, bipedal, opposing-thumbed - selves. view more (2009-07-27)
Orphan army ants join nearby colonies
Colonies of army ants, whose long columns and marauding habits are the stuff of natural-history legend, are usually antagonistic to each other, attacking soldiers from rival colonies in border disputes that keep the colonies separate. view more (2009-11-05)
Fire ants are emerging nuisance for Virginians
Red imported fire ants (RIFAs), which have caused trouble in Florida and Texas for decades, are now advancing in Virginia. view more (2007-05-24)
