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...

Some Wasps Developed Bigger Eyes To See Social Cues Better
2014-04-30 03:57:42

Robert Sanders, University of California - Berkeley Social communication drove evolution of larger facets in acute zone of compound eye Some wasps have developed bigger eyes, and thus better vision, to read the social cues written on the faces of their sister wasps, according to a new University of California, Berkeley, study. "The Big Bad Wolf had it right," said lead author Michael Sheehan, a UC Berkeley postdoctoral fellow. "When Little Red Riding Hood said, 'Goodness, what big...

Digitizing Insects In 3-D Using 'Off-the-shelf' Equipment
2014-04-25 03:41:52

PLOS 3-D model insects useful for studying, sharing specimens Scientists have developed a cost-effective, off-the-shelf system to obtain natural-color 3D models of insects, according to results published April 23, 2014, in the open access journal PLOS ONE by Chuong Nguyen from CSIRO in Australia, and colleagues. Scientists studying insects rely on collected specimens that are often shared between scientists through written descriptions, diagrams, and images. These 2D tools are...

Researchers Discover Cave Insects With Sex-reversed Genitalia
2014-04-18 09:04:10

Cell Press Researchers reporting in the Cell Press journal Current Biology on April 17 have discovered little-known cave insects with rather novel sex lives. The Brazilian insects, which represent four distinct but related species in the genus Neotrogla, are the first example of an animal with sex-reversed genitalia. "Although sex-role reversal has been identified in several different animals, Neotrogla is the only example in which the intromittent organ is also reversed," says Kazunori...

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...

Attracting Or Repelling Insects Using Different Scents
2014-04-01 15:48:26

University of Zurich Flowering plants attract pollinating insects with scent from their flowers and bright colors. If they have become infested with herbivores like caterpillars, they attract beneficial insects like parasitic wasps with the help of scent signals from their leaves. The wasps then lay their eggs in the caterpillars and kill the parasites. Floral and foliar scents can, however, mutually reduce their attractiveness. That's why flowering plants face a dilemma: should they use...

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...

Specialization By Insect Species Is The Key
2014-03-14 14:54:57

University of Iowa Most of us already imagine the tropics as a place of diversity—a lush region of the globe teeming with a wide variety of exotic plants and animals. But for researchers Andrew Forbes and Marty Condon, there's even more diversity than meets the eye. In a paper published in the March 14 issue of the journal Science, Forbes and Condon report the discovery of extraordinary diversity and specialization in the tropics. The paper builds upon previous research conducted...

Leaf Insects, Phylliidae
2014-08-05 10:01:39

Phylliidae is a family of insects most commonly known as leaf insects or walking leaves, which can be found in Southeast Asia and South Asia to Australia. Although it is classified as a family, there is no general agreement on its classification, as many suggest that the family is actually a large taxon that should contain separate families of leaf insects. It is thought that this family has changed little over long periods of time, due to fossil evidence found of a forty-seven million year...

Tetragnatha extensa
2013-10-09 13:17:36

Tetragnatha extensa is a species of spider found across the Northern Hemisphere. It has an elongate body, up to .43 inches long, and assumes a straight line posture when it is alarmed. It lives on low vegetation in damp areas and consumes flying insects which it catches in its web. This spider has a stretched out, cream colored body. The males are smaller than the females at around .35 inches body length, compared to .43 inches in the females. The four pairs of legs are long and a dark...
