Leaf Chewing Links Insect Diversity In Tropical Forests
2014-05-05 03:53:42

By A'ndrea Elyse Messer, Penn State Observations of insects and their feeding marks on leaves in modern forests confirm indications from fossil leaf deposits that the diversity of chewing damage relates directly to diversity of the insect population that created it, according to an international team of researchers. "The direct link between richness of leaf-chewing insects and their feeding damage across host plants in two tropical forests validates the underlying assumptions of many...

Insect Shield blankets offer invisible, odorless protection from a variety of insects that can carry Lyme disease, West Nile virus, malaria and other insect-borne diseases. Greensboro, NC & Seattle, WA (PRWEB) April 15, 2014 Spring is here which means the bugs are on their way... It is time to get ready for the annual battle against Spring/Summer insects. According to the CDC, Lyme disease has become an epidemic - and not just in the Northeast. More than 300,000 cases of Lyme are...

Fruit Flies Use Not Just Eyes, But Antennae To Control Air Speed
2014-04-11 14:20:00

Brett Smith for redOrbit.com - Your Universe Online Geneticists may know the fruit fly genus Drosophila as go-to organisms for their research, but a new study focused instead on how these insects go into a sort of “cruise control” while in flight. Using bursts of air and sophisticated software, the new study revealed that fruit flies use a combination of vision and their wind-sensitive antennae to maintain a constant flight speed relative to the ground. The new study, published in...

Parasitic Butterfly Larvae May Use Acoustic Signals To Infiltrate Ant Colonies
2014-04-10 15:57:05

PLOS Parasitic butterfly larvae may mimic ants' acoustic signals to aid in the infiltration of their host colonies, according to results published April 9, 2014, in the open access journal PLOS ONE by Marco Sala from University of Turin, Italy, and colleagues. Ants aggressively defend their colonies and nests, so successfully that these locations make a perfect shelter for another similar species to live in. However, ants have evolved a complex set of signals that allow colony members...

3D Movie From Inside Live Flying Insects
2014-03-31 09:11:47

[ Watch The Video: Three-Dimensional Visualization of the Insect Thorax ] University of Oxford The flight muscles moving inside flies have been filmed for the first time using a new 3D X-ray scanning technique. 3D movies of the muscles were created by a team from Oxford University, Imperial College London, and the Paul Scherrer Institute (PSI), using the PSI's Swiss Light Source, a powerful X-ray source. The movies offer a glimpse into the inner workings of one of nature's most...

Earliest Stick Insect Fossils Discovered
2014-03-20 08:06:36

PLOS Wing shape and coloration pattern suggest plant-mimicking stick insects from the Early Cretaceous An ancient stick insect species may have mimicked plant leaves for defense, according to a paper published in the open-access journal PLOS ONE on March 19, 2014 by Maomin Wang, from Capital Normal University, China and colleagues. Many insects have developed defense mechanisms, including the ability to mimic the surrounding environment. Stick and leaf insects mimic plants from...

Fire Ants Being Displaced By Venom-Neutralizing Crazy Ants
2014-02-14 07:08:22

[ Watch the Video: Crazy Ants Attack Fire Ants ] April Flowers for redOrbit.com - Your Universe Online In areas across the southeastern United States, invasive "crazy ants" are rapidly displacing fire ants by secreting a compound that neutralizes the fire ant's venom, according to a new study from The University of Texas at Austin. The crazy ant is the first known example of an insect with the ability to detoxify another insect's venom. The latest in a wave of ant invasions from the...

Genetically Modified Bt Crops Do Not Affect Non-Targeted Insects And Nematode Worms
2014-02-03 09:16:55

Brett Smith for redOrbit.com - Your Universe Online Some crops have been genetically modified to produce toxins from the bacterium Bacillus thuringiensis (Bt) that protect them from insect pests. These modified crops have raised concerns that they may have unintended consequences for other organisms. Two new studies have found that these crops have little or no effect on non-targeted insects and nematode worms. In one of the studies, published in the February 2014 issue of...

World's First Butterfly Bacteria Sequenced
2014-01-30 14:24:03

University of Colorado at Boulder For the first time ever, a team led by the University of Colorado Boulder has sequenced the internal bacterial makeup of the three major life stages of a butterfly species, a project that showed some surprising events occur during metamorphosis. The team, led by CU-Boulder doctoral student Tobin Hammer, used powerful DNA sequencing methods to characterize bacterial communities inhabiting caterpillars, pupae and adults of Heliconius erato, commonly known...

How Gene Expression Differs Between Castes In Ants
2014-01-30 11:53:06

Johannes Gutenberg University Mainz Novel or highly modified genes play a major role in the development of the different castes within ant colonies. Evolutionary biologists at Johannes Gutenberg University Mainz (JGU) came to this conclusion in a recent gene expression study. Dr. Barbara Feldmeyer and her colleagues at the JGU Institute of Zoology studied the question how the different female castes arise. An ant colony generally consists of a queen and the workers. Moreover, workers can...

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...
