Uloboridae
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body. Description They are medium to large spiders, with tree claws, which lack venomous glands. They build a spiral web using cribellate silk, which is quite fuzzy. They are usually dull in color, and are able to camouflage well into their surroundings. Usually having a humped opisthosoma, which is notoriously more humped than the carapace. Their rear eyes curving, in some species stronger than others. Hunting The hunting method of these spiders is quite unique among all animals in the kingdom. These spiders do not use an adhesive on their orb webs, but rather the very fine cribellate fibers on each strand of silk tend to ensnare prey. Since newly hatched uloborids lack the cribellum needed to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philoponella Republicana
''Philoponella'' is a genus of uloborid spiders. Like all Uloboridae, these species have no venom. Cooperation Some species (among them ''P. congregabilis'' and ''P. oweni'') construct communal webs, but nevertheless do not capture prey cooperatively. However, a few species, such as ''P. raffrayi'', are known to cooperate in prey capture. A colony of ''P. raffrayi'' is composed of individual orb-webs connected by non-adhesive silk. Its average body length is about 6 mm in females and 3 mm in males. Adult females are orange for at least a week after the final molt, and become black a few weeks later. In these colonies, ''Argyrodes'' and '' Portia'' species can also be found, acting as kleptoparasites and predators, respectively. When relatively large prey is trapped on the periphery of the colony, two females cooperate in about 10% of cases in wrapping it, which increases their chances of success about fourfold. However, only one female then feeds on this prey. Cooperat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hyptiotes Paradoxus
''Hyptiotes paradoxus'', also known as the triangle spider, is a cribellate orbweaver in the family Uloboridae. Description Body Adult males have a body length of 3–4 mm (0.12–0.16 in), females 5–6 mm (0.20–0.24 in). The carapace is Broad. It ranges from ginger to dark brown, and has a dense covering of hairs. The abdomen is orange-brown to reddish-brown, with faint black horizontal bands which extend around the sides. It is raised towards the anterior, giving the spider a hunched look, and it may bear a pair of small tubercules on the anterior side. The male has a darker and more cylindrical abdomen than the female, and it lacks the raised anterior. They have short, stout legs, which are coloured as the carapace. Mature males have extremely large pedipalps, similar in size to the carapace. Eye arrangement They have eight eyes in two rows, with the posterior row distributed across the midline of the carapace, and the anterior row halfway between the posterior row ...

Uloborus Glomosus
''Uloborus glomosus'' is a species of spider in the family Uloboridae. It is one of only a few ''Uloborus'' species found in North America and the only species found in Canada. Like all other species in the Uloboridae, ''Uloborus glomosus'' does not possess venom glands, relying instead on cribellate Cribellum literally means "little sieve", and in biology the term generally applies to anatomical structures in the form of tiny perforated plates. In certain groups of diatoms it refers to microscopically punctured regions of the frustule, or o ..., a fuzzy non sticky silk that they use to trap and then wrap their prey. This species exhibits different disturbance behaviors depending on whether there are eggsacs present. If present the female spider will jerk at the web and if not present, then the female spider will walk to the opposite side of the web.

Hyptiotes
''Hyptiotes'' is a genus of spiders in the family Uloboridae. Feeding ''Hyptiotes'' creates a triangular web and sits at a vertex until it detects vibrations that signify the collision of its prey. At this moment the spider releases a coil of silk which it has held taut in such a manner that the tension of the web causes it to entangle the prey. The spider then wraps its prey in special wrapping silk.David Attenborough, 2005, Life In the Undergrowth, Episode 3, 23 mins 15 secs ff.

Spider
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had ...

Uloborus Plumipes
''Uloborus plumipes'' is a species of Old World cribellate spider in the family Uloboridae. Common names include the feather-legged lace weaver and the garden centre spider, the latter name being due to its frequent occurrence of this spider in garden centres. The species name is derived from the Latin ''pluma'' "feather" and ''pes'' "foot". Females grow up to 6 mm. They lack venom glands, and are therefore non-venomous. A stabilimentum is sometimes present. Pattern and colouration is quite variable. In contrast to '' Uloborus walckenaerius'', it has distinct tufts of hairs on the front legs. They are well-camouflaged as they hang upside down motionlessly in their horizontal webs. Young spiders look like dead insects and are thus hard to find on a web. The empty egg sac can often be seen attached to house plants. It is flattish, papery and brown and about 0.5 cm long, with the shape of a dried holly leaf.
