Smithsonian researchers report that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. As part of ongoing research to understand how miniaturization affects brain size and behavior, researchers measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities....

Blueprint of spider mite may yield better pesticides A University of Utah biologist and an international research team decoded the genetic blueprint of the two-spotted spider mite, raising hope for new ways to attack the major pest, which resists pesticides and destroys crops and ornamental plants worldwide. The voracious mites, which technically are not insects, can eat more than 1,100 plant species — a rare trait. The mites' newly revealed and sequenced genome contains a variety...

Researchers have shown for the first time how Golden orb web spiders (Nephila antipodiana) add a chemical to their web silk to repel invading ants. The finding adds a chemical defense to the impressive properties of spider silk, already known to be very strong, elastic and adhesive, and may provide new opportunities for pesticide design. The study was led by researchers from the National University of Singapore (NUS) and the University of Melbourne, and is published in the journal...

Deceitful Spider Pays For Sex And Plays Dead
2011-11-14 05:26:11

Male nursery web spiders (Pisaura mirabilis) prepare silk-wrapped gifts to give to potential mates. Most gifts contain insects, but some gifts are inedible plant seeds or empty exoskeletons left after the prey has already been eaten (presumably by the male himself!). Males will also 'play dead' if a female moves away and then attempt to re-establish mating. New research published in BioMed Central's open access journal BMC Evolutionary Biology examines the reproductive success of deceitful...

"The strength of spider dragline silk exceeds that of any material produced in laboratories, by far. All attempts to manufacture threads of similar strength have failed thus far," explains Professor Horst Kessler, Carl von Linde Professor at the Institute for Advanced Study at the TU Muenchen (TUM-IAS). In collaboration with the workgroup of Prof. Thomas Scheibel, who was a researcher at the TU Muenchen until 2007 and who now holds a chair of the Institute of Biomaterials at the Universitaet...

(Ivanhoe Newswire) -- Young house spiders weave webs with perfect angles and regular patterns, but as they reach old age their webs deteriorate, showing gaping holes and erratic weaving. By using spiders as a simple model this research may provide insight into how age affects behavior in other organisms, including humans. The reason web building skills are lost as spiders grow older may be due to degeneration of the central nervous system. PhD researcher, Mylne Anotaux, from Nancy University...

It has 8 hairy legs, spins webs, hunts prey and lives its entire life under the surface of the water. No, it is not the something from a bad horror film, the Argyroneta aquatica, or Diving Bell Spider is the subject of a fascinating study published in the Journal of Experimental Biology. "It is an iconic animal; I had read about the spider as a small boy in popular literature about ponds," says Roger Seymour from the University of Adelaide. Each spider constructs a net of silk in vegetation...

A spectacular golden textile, conceived and created by Simon Peers and Nicholas Godley in Madagascar from silk thread collected from over one million Golden Orb spiders (Nephila madagascariensis), will go on exhibit at the Art Institute of Chicago, the country's second largest art museum. On special loan to the museum from Mssrs. Peers and Godley as part of the inaugural celebration of the museum's new galleries devoted to African art and Indian art of the Americas, the Spider Silk textile...

Skeleton Tarantula, Ephebopus murinus
2014-08-29 11:32:08

The Skeleton Tarantula (Ephebopus murinus) is a species of spider belonging to the Theraphosidae family, a sub-family of Aviculariinae. This New World species is native to several South American countries. Its common name comes from the skeleton-like markings on its legs. The generic name, Ephebopus comes from the Greek meaning “youthful” plus “foot”, and the specific name, murinus is from the Latin meaning “mouse-colored”. The adult E. murinus normally grows to a leg span of...

Cobweb Spider, Theridiidae
2014-06-23 08:44:11

Theridiidae is a family that contains over 2,200 species of cobweb spiders, also known as tangle-web spiders or comb-footed spiders, which can be found throughout the world. This species received its common names from its tendency to build three dimensional, sticky webs and from the comb of serrated bristles on the fourth leg. It is thought that this family is the only to hold a high diversity of web types, including gumfooted webs, which are highly similar to those produced by spiders in the...

Wolf Spider, Lycosidae
2014-06-23 08:30:31

Lycosidae is a family that holds about 2,300 species of wolf spiders that can be found in a variety of habitats including woodlands, gardens, and moist coastal areas. Many species do require specific microhabitats, like montane herb-fields, but most species are nomads and do not reside in one area for long periods of time. Some species within this family build burrows that can have trap doors or open entrances, while others in arid regions build nests with plugged entrance ways, to protect...

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...

Sparassidae is a family that holds over one thousand species of huntsman spiders, also known as giant crab spiders and wood spiders, or as rain spiders or lizard-eating spiders in some areas of its range. These species are native to Australia but were also introduced to temperate areas throughout the world including China, Japan, and some areas of the United States, including Florida and Hawaii. They inhabit warmer areas and can often be seen entering human habitations and other shelters...
