Like silkworm moths, butterflies and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, University of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery. "Silk from caddisfly larvae "“ known to western fly fishermen as 'rock rollers' "“ may be useful some day as a medical bioadhesive for sticking to wet tissues," says Russell Stewart, an associate...

Just because cricket moms abandon their eggs before they hatch doesn't mean they don't pass wisdom along to their babies. New research in the American Naturalist shows that crickets can warn their unborn babies about potential predator threats. Researchers Jonathan Storm of the University of South Carolina Upstate in Spartanburg and Steven Lima of Indiana State University placed pregnant crickets into enclosures containing a wolf spider. The spiders' fangs were covered with wax so the spiders...

Scorpion venom is notoriously poisonous "” but it might be used as an alternative to dangerous and addictive painkillers like morphine, a Tel Aviv University researcher claims. Prof. Michael Gurevitz of Tel Aviv University's Department of Plant Sciences is investigating new ways for developing a novel painkiller based on natural compounds found in the venom of scorpions. These compounds have gone through millions of years of evolution and some show high efficacy and specificity for...

A spider may be the reason fog-catching nets, which provide precious water in rain-starved parts of the world, may be ready for a high-tech upgrade. Chinese scientists reported their research in the journal Nature on why spider's silk is not only famous for strength but also terrific for collecting water from the air, sparing the creature the hunt for a drink. The secret lies in the silk's tail-shaped protein fibers that change structure in response to water. The tiny section of thread...

The new species is the largest of its type in the Middle East, but its habitat is endangered A new and previously unknown species of spider has been discovered in the dune of the Sands of Samar in the southern Arava region by a team of scientists from the Department of Biology in the University of Haifa-Oranim. Unfortunately, however, its habitat is endangered. "The discovery of this new spider illustrates our obligation to preserve the dune," says Dr. Shanas, who headed the team of...

With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. The findings are an advance toward a new generation of biobased adhesives and glues "” "green" glues that replace existing petroleum-based products for a range of uses. A report on the study was published in ACS' Biomacromolecules, a monthly journal....

Scientists have confirmed that spider webs discovered in Britain are the oldest on record, dating back 140 million years to the Cretaceous period. The webs, which were enclosed in amber, were discovered on a beach in East Sussex by fossil hunter Jamie Hiscocks and his brother Jonathan. Professor Martin Brasier, a paleobiologist at the Oxford University, said the fossils were the earliest spider webs ever to be entered into the fossil record. "This amber is very rare. It comes from the very...

A Central American species of spider, known as Bagheera kiplingi (B. kiplingi), represents the first known instance to science of an arachnid that dines primarily on plants. About 40,000 unique spiders have been described to date, with most considered strict predators that either trap their prey in intricate webs or hunt them down directly. The newly-discovered vegetarian spider primarily consumes something called Beltian bodies, specialized leaf-tip structures produced by acacia shrubs....

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...

Funnel Weavers, Agelenidae
2014-06-19 13:16:37

Agelenidae is a family that holds about 1,200 recognized species of funnel weaver spiders that occur throughout the world. These spiders build funnel shaped webs that trap prey in their complicated patterns, but they should not be confused with other families of spiders that build funnel webs like funnel-web spiders or funnel-web tarantulas. Funnel weavers can reach an average body length between .1 inches in the smallest species and .7 inches, although the largest species can reach total...

The Cellar Spider (Pholcus phalangioides), known also as the Skull Spider because of its cephalothorax resembling a human skull, is a spider belonging to the family Pholcidae. The females have a body length of about 9 millimeters; the males are slightly smaller. The legs are about 5 to 6 times the length of the body. Its habit of living on the ceilings of room, garages, caves, or cellars gives rise to one of its common names. They are thought to be beneficial in some parts of the world...
