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 is in the October issue of ACS' Biomacromolecules, a monthly...

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...

A Chinese team of scientists has identified the protein composition of venom from the Scorpiops jendeki scorpion. Wuhan University researchers said their findings -- from the first venom analysis of the arachnid -- uncovered nine novel poison molecules never before seen in a scorpion species. The scientists led by Yibao Ma of the university's Laboratory of Virology studied the sting of S. jendeki, a member of the family Euscorpiidae, which covers Europe, Asia, Africa and North America. Our...

Transcriptomic tests have uncovered the protein composition of venom from the Scorpiops jendeki scorpion. Researchers writing in the open access journal BMC Genomics have carried out the first ever venom analysis in this arachnid, and discovered nine novel poison molecules, never before seen in any scorpion species. Yibao Ma worked with a team of researchers from Wuhan University, China, to study the sting of S. jendeki, a member of the family Euscorpiidae, which covers Europe, Asia, Africa,...

Scientists have strengthened spider silk three times more than its natural durability - which is already tougher and lighter than steel - by infusing the silk with small bits of metal, Reuters reported. This procedure may prove beneficial for developing extremely durable textiles as well as high-tech medical materials like artificial bones and tendons. Researcher Seung-Mo Lee of the Max Planck Institute of Microstructure Physics in Halle, Germany suggested the infused spider silk "could make...

A parade celebrating the 150th anniversary of a Japanese port's opening included a pair of 40-foot-tall mechanical spiders. The spiders, operated by French performance art group La Machine, walked Sunday by raising and lowering each of their eight mammoth legs in turn and sprayed water from their mechanical mouths, the Kyodo news agency reported Monday. The parade, which celebrated the 150th anniversary of Yokohama port, was attended by an estimated 500,000 people, organizers said.

A researcher at the University of Kansas has discovered a link between ancient spiders and their modern relatives. Scientists have often debated about the origin of the silk spiders use to spin webs, said Paul Selden, director of the Paleontological Institute at the Biodiversity Institute and professor of invertebrate paleontology at Kansas University. Selden discovered that what researchers had previously considered to have been web-spinning appendages located on the fossilized remains of...

MU entomologist warns of the venomous brown recluse spider's bite As the cold weather creeps in, so do brown recluse spiders. True to their name, the brown recluse is a shy, reclusive spider looking for a warm home. Drawn to clutter, closets and complex storage environments, the spiders actually want to stay away from humans. But, if care is not taken, people could find themselves sharing their home with one of 'the big three,' according to a University of Missouri entomologist. The brown...

Cellar Spider, Pholcus phalangioides
2014-04-07 13:05:31

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...

Tailed Daddy Longlegs Spider, Crossopriza lyoni

Crossopriza lyoni is a widespread species of cellar spiders that prefer to live in or around human structures. They are commonly known as Tailed Cellar Spiders, Tailed Daddy Longlegs Spiders, and occasionally Box Spiders. They all possess exceptionally long and fragile legs that can reach up to 2.4 inches long and a body length of that ranges from .098 to .28 inches. Their abdomens are distinctly square shaped when they are viewed from the side and their carapace is more or less circular...

The coloration varies from light brown to yellow-brown to a darker reddish brown color, with no markings on its abdomen. Their chelicerae...

Arachnology
2012-10-15 15:14:24

Arachnology is the scientific study of spiders and related specimens: including scorpions, pseudo-scorpions and harvestmen. These animals are collectively known as arachnids. Ticks and mites, on the other hand, although are in the arachnid family, do not typically fall under archeology studies; these small creatures are usually studied under Acarology. Arachnology derives from the Greek words arachne (meaning spider), and logia (meaning sayings). People who study spiders and other...
