Social insects - ants in particular - are usually thought of as selfless entities willing to sacrifice everything for their comrades. However, new research suggests that ant queens are also prepared to compromise the welfare of the entire colony in order to retain the throne. A team from the University of Copenhagen, led by postdoc Luke Holman of the Center for Social Evolution, describes in Proceedings of the Royal Society B, published on February 24, 2010, that ant queens are much more...

A study published today in Science, by researchers at Rothamsted Research (an institute of the BBSRC), the Met Office, the Natural Resources Institute, and the Universities of Exeter, Greenwich and York, sheds new light on the flight behaviors that enable insects to undertake long-distance migrations, and highlights the remarkable abilities of these insect migrants. Many insects avoid cold British winters by migrating south in autumn to over-wintering sites around the Mediterranean. Migrant...

Insects, a popular delicacy in many parts of the world, are getting a culinary makeover in one Central American city, where scientists are "Ëœgrowing' insects that will be tailored for human consumption. The idea for a common sustainable diet in many African cultures caught the eye of entomologist Manuel Zumbado, who began researching insects as an alternative food source. With the rainforest in mind, Costa Rica has a countless supply of insect species, which may include thousands...

Going about their day-to-day business, bees have no need to be able to recognize human faces. Yet in 2005, when Adrian Dyer from Monash University trained the fascinating insects to associate pictures of human faces with tasty sugar snacks, they seemed to be able to do just that. But Martin Giurfa from the Universit© de Toulouse, France, suspected that that the bees weren't learning to recognize people. 'Because the insects were rewarded with a drop of sugar when they chose human...

UMass Medical School neurobiologists use transgenic fruit flies and monarch butterfly transgenes to help define magnetoreception mechanism Building on prior investigation into the biological mechanisms through which monarch butterflies are able to migrate up to 2,000 miles from eastern North America to a particular forest in Mexico each year, neurobiologists at the University of Massachusetts Medical School (UMMS) have linked two related photoreceptor proteins found in butterflies to animal...

Scientists have shown for the first time that insects, like mammals, use vision rather than touch to find footholds. They made the discovery thanks to high-speed video cameras "“ technology the BBC uses to capture its stunning wildlife footage "“ which they used to film desert locusts stepping along the rungs of a miniature ladder. The study sheds new light on insects' ability to perform complex tasks, such as visually-guided limb control, usually associated with mammals....

Discovery offers opportunity to develop new environmentally safe ways to control pests A team of University of Minnesota researchers have discovered how PTTH, a hormone produced by the brain, controls the metamorphosis of juvenile insects into adults. The finding, published in the Dec. 4 issue of Science, will help scientists understand how insect body size is programmed in response to developmental and environmental cues and offers the opportunity to develop a new generation of more...

For the first time, scientists at The University of Western Ontario have shown that insects exposed to repeated periods of cold will trade reproduction for immediate survival. The study, conducted by Biology PhD candidate Katie Marshall and supervisor Brent Sinclair, has been published online Nov. 25 by the prestigious journal, Proceedings of the Royal Society B. Results showed flies exposed to multiple bouts of cold survived better, but produced fewer offspring.  Past research had...

Since 1996, crop plants genetically modified to produce bacterial proteins that are toxic to certain insects, yet safe for people, have been planted on more than 200 million hectares worldwide. The popularity of these Bt crops, named after the bacterium Bacillus thuringiensis, comes from their ability to kill some major pests, allowing farmers to save money and lessen environmental impacts by reducing insecticide sprays. However, since insects can evolve resistance to toxins, strategies must...

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

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, 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...
