Social Chromosomes Determine How Many Queen Ants Are In Fire Ant Colony
2013-01-17 13:19:53

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Nature that they discovered a social chromosome in fire ants that explain why some colonies allow for more than one queen ant. Red fire ants live in two different types of colonies, including some that strictly have a single queen, and others that contain hundreds of queens. Scientists discovered that this difference in social organization is determined by a chromosome that carries one of two...

After metamorphosis European forest cockchafers benefit from the same bacterial symbionts housed during their larval stage. Apart from the common European cockchafer (Melolontha melolontha), the European forest cockchafer (Melolontha hippocastani) is the most common species of the Melolontha genus. These insects can damage huge areas of broadleaf trees and conifers in woodlands and on heaths. Cockchafers house microbes in their guts that help them to digest their woody food, such as...

Insects Found To Have Similar Hearing System To That Of Dolphins
2012-12-14 11:00:01

April Flowers for redOrbit.com - Your Universe Online Scientists have discovered a hearing system component previously thought to be unique to toothed whales — such as dolphins — in insects. The team, comprised of scientists from the School of Biological Sciences at the University of Auckland, with colleagues from Plant & Food Research in New Zealand, and engineers from the University of Strathclyde in Glasgow, Scotland, is challenging ideas about how a large group...

Insect Diversity Studied In The Rainforests Of Panama
2012-12-14 05:46:43

April Flowers for redOrbit.com - Your Universe Online Until now, scientists have had a problem estimating the exact numbers of arthropods — a group that includes insects, arachnids, and crustaceans - on Earth, even though we know they comprise a majority of the multicellular species on the planet. Because of their small size, frequent movements, and inaccessible habitats, quantifying their abundance has been difficult despite the fact that they are the most numerous phylum on the...

Researchers find that gene related to germ cell formation is far older than first thought Harvard scientists have solved the long-standing mystery of how some insects form the germ cells — the cellular precursors to the eggs and sperm necessary for sexual reproduction — and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process. As described in a November 1 paper published in Current Biology, a team of...

Ant Slave Rebellion
2012-09-26 19:13:14

Michael Harper for redOrbit.com — Your Universe Online There´s new evidence today ants that have been captured and made slaves by other ants aren´t simply taking their plights lying down. According to a new study, these slave ants are prone to try and take down their oppressors by sabotaging their families. The first signs of this kind of ant rebellion were noted by Johannes Gutenberg University Mainz (JGU) research professor Dr. Susanne Foitzik in 2009. However, in the...

Collective decision-making proves more efficient than individual selection Scientists at Arizona State University have discovered that ants utilize a strategy to handle "information overload." Temnothorax rugatulus ants, commonly found living in rock crevices in the Southwest, place the burden of making complicated decisions on the backs of the entire colony, rather than on an individual ant. In a study published in the early, online version of scientific journal Current Biology,...

Rasberry Crazy Ants Get Scientific Name Recognition
2012-09-21 09:04:47

Alan McStravick for redOrbit.com - Your Universe Online Ten years is a long time to not have a name. The ℠Rasberry Crazy Ant´, so called for their propensity to swarm in seemingly random, quick moving circles, was first noticed in the South Texas area over a decade ago by Tom Rasberry, a local exterminator who took an immediate interest in this rarely-before-seen invader. Rasberry knew very early on through his attempts to eradicate entire colonies that the infestation would...

Multi-Colored Stick Bug Discovered In Philippines
2012-09-04 14:24:33

Lee Rannals for redOrbit.com — Your Universe Online Scientists have discovered a new stick insect living in the Philippines that spends its days on the ground, rather than in trees. The new wingless species is colored with blues, greens, tans, and some orange around the joints along its back. This six-legged creature, Conlephasma enigma, was discovered by Marco Gottardo, a scientist from University of Siena, Italy and Phillipp Heller from Switzerland. It was found on the third...

April Flowers for redOrbit.com - Your Universe Online One thousand rare and protected ants have been fitted with tiny little backpacks to try and understand the social network of how a colony works. A research team from the University of York is fitting tiny radio receivers to a colony of hairy wood ants in the world's first experiment to find out how they communicate and travel between nests. The nests are located on the National Trust's Longshaw Estate in Derbyshire, UK, which is a...

Entomology
2013-10-01 10:34:23

Entomology, a branch of arthropodology, is the study of insects. In the past, the term insect was used to refer to species from other phyla or groups including arachnids, slugs, and earthworms. This view of entomology is still used in informal settings today. Entomology extends through cross sections of science including paleontology, biochemistry, and nutrition, among many others. There are 1.3 million species of insects throughout the world, so entomology covers a large base of research...

Myrmecology
2013-09-30 16:20:45

Myrmecology, a branch of entomology, is the study of ants that has focused on many factors about ants, including evolution and social systems. William Morton Wheeler first used the term myrmecology, but the study of ants predates the usage of the term, going back to ancient references of ants. Auguste Forel, a Swiss psychologist, conducted the first scientific studies of ants, focusing on the roles of instinct and learning in a society. He published Les fourmis de la Suisse in 1874 after...

Inchman, Myrmecia forficate
2013-07-10 12:28:46

The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks.  It reaches an average body length of up to one inch long, the trait from which it received its common name. The inchman is both a scavenger and a...

Rhithrogena germanica

Rhithrogena germanica, known as the March brown mayfly in in the British Isle, is a species of mayfly that can be found throughout northern and central areas of Europe. Its range includes the River Tweed in England, Hesse in Germany, Denmark, Poland, and France. It was first described by Alfred Edwin Eaton, who studied a male specimen from the River Rhine. Rhithrogena germanica begins its lifecycle in the larval stage, as a water dwelling naiad that is typically found in fast flowing,...

The Argema mittrei, more commonly known as the Comet or Moon Moth, is an endangered species. It is a native of Madagascar and that is the only place where one can observe them in the wild. This large silk moth can be bred in captivity and is one of the world's largest moths. Males have an average wing span of nearly 8 inches and a tail span of almost 6 inches. The lifespan of an adult moth is only 4-5 days and they are capable of reproduction from day 1. Their cocoons are uniquely...
