Early relatives of spiders that lived around 300 million years ago are revealed in new three-dimensional models, in research published today in the journal Biology Letters.Scientists at Imperial College London have created detailed 3D computer models of two fossilized specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The study reveals some of the physical traits that helped them to hunt for prey and evade predators.The...

After 10 years of biochemical and molecular analysis of the Tyrrhenoleuctra plecoptera that live in the Western Mediterranean, Spanish and Italian scientists have now demonstrated that one of the insect populations of this group is a distinct and, therefore, new species.The researchers, including a team from the University of Granada (UGR), used biochemical and molecular techniques for a decade to detail the taxonomical and phylogenetic relationships of the insects of the Tyrrhenoleuctra...

Animals can simplify the brain control of their limb movements by moving a joint with just one muscle that operates against a spring made of the almost perfect elastic substance called resilin. This principle is analyzed and illustrated by striking photographs and high-speed video footage, published in the open access journal BMC Biology, of the movements of the mouthparts of crabs and crayfish. Malcolm Burrows from the University of Cambridge, UK investigated the presence of resilin, an...

A Malaysian insect, at 22 inches the longest insect in the world, is among the top 10 species found in 2008, Arizona State University says. The college's International Institute for Species Exploration said the large insect was picked by an international committee of scientists to make the annual list, along with the world's smallest snake, The Arizona Republic said Saturday. The snake, found in Barbados, is only the size of a quarter, but it is not the smallest species to make the...

A recent study has shown that earwig mothers are able to detect odors from the unhealthiest "nymphs" of their brood and accordingly adjust their behavior to ensure that the fittest young receive more attention than their siblings. Though frequent amongst many higher classes of animals, this study was the first of its kind to demonstrate such behavior in insects. For earwig parents, it seems that the name of the game is favoritism.  When the mother detects chemical signals released from...

 Tiny mites living on the surface of Madagascar hissing cockroaches help decrease the  presence of a variety of molds on the cockroaches' bodies, potentially reducing allergic responses among humans who handle the popular insects, according to new research.Scientists cultured and identified fungi on the cockroaches' body surfaces with and without mites and discovered that the presence of these mites reduced the molds by at least 50 percent.Many of these same researchers reported a...

Hurdia victoria was originally described in 1912 as a crustacean-like animal. Now, researchers from Uppsala University and colleagues reveal it to be just one part of a complex and remarkable new animal that has an important story to tell about the origin of the largest group of living animals, the arthropods. The findings are being published in this week's issue of Science. The fossil fragments puzzled together come from the famous 505 million year old Burgess Shale, a UNESCO World Heritage...

A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390 million-year-old fossil by researchers at Yale and the University of Bonn, Germany. The specimen, named Schinderhannes bartelsi, was found fossilized in slate from a quarry near Bundenbach in Germany, a site that yields spectacularly durable pyrite-preserved fossils "” findings collectively known as the Hunsrck Slate. The Hunsrck Slate has previously...

Atlas of Scanning Electron Microscope Images of the Book Lung Published by the American Museum of Natural History Modern microscopy technology has allowed two scorpion biologists, Carsten Kamenz of the Humboldt University in Berlin and Lorenzo Prendini of the American Museum of Natural History, to study and document what is nearly invisible. Looking at tiny morphological features like the sculpting of the hair-like outgrowths on lamellae"”structures that fold like the leaves of a book...

300 million-year-old discovery in an unlikely setting -- a suburban strip mall While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass. During a recent exploration as part of his senior project, Richard J. Knecht, a Tufts geology major, and Jake Benner, a paleontologist and...

Image Caption: House Centipede, Scutigera coleoptrata. Credit: Bruce Marlin/Wikipedia  (CC BY 3.0) Scutigera coleoptrata is one of many species of house centipedes. This species is native to the Mediterranean, but it is capable of moving to other region of the world including most of Europe, South America, North America, and Asia. It is thought to have first ventured from its native range into Mexico and Guatemala, and its range has now stretched into Argentina in the south and Canada in...

The Jerusalem cricket (Stenopelmatus) is a genus of large, flightless insects native to western United States, along the Pacific Coast, and south into Mexico. Because of its large, human-like head, it is commonly called the nino de la tierra (Spanish for "child of the earth"), or wó see ts'inii (Navajo for "skull insect"). It is also often called the potato bug, or alternatively the old bald-headed man. Despite their name, Jerusalem crickets are not true crickets. Also, Potato bugs are...
