Orb Weaver Spider

The Life of Animals | Orb Weaver Spider | In general, three claws builder web spiders with webs flat spiral of sticky capture silk. The spider holds the line and then falls other center line, so that a "Y". The third clamp is used to remove the non-sticky web. One feature is that the errors of insect prey in sticky lines is stunned by a quick snack and then wrapped in silk. If the prey is a venomous insect, like a wasp, wrapping may precede biting. Many orb-weaving spiders build a new web each day. In general, the night will consume the spider, the old network rest for approximately one hour, then weaving a web again in the same general location.Some spiders do not build webs at all. Interestingly, both types of balls spiders are highly camouflaged and difficult to locate. The spiny orb-weaving spiders in the genera Gasteracantha Micrathena and look like plant seeds or thorns stuck in their bullet trains. A feature of the orbits of some orb-weavers is stabilimentum, a silk ribbon crossed the center of the web. It is found in a number of genera, but Argiope, which includes the common garden spider of Europe and the yellow garden spiders and tracks of North America, is an excellent example.


The orb web is made of a frame and support beams with a sticky capture spiral superimposed and used spider silk Radspinne exceptional mechanical properties, the impact of flying prey to resist. The orb web of substrate on the web, probably derived from a web uneven ground or brushed sheet web. The change of a Web-ground with an antenna for horizontal and vertical web of bike trails, was authorized to capture prey flight. Fossil evidence shows that the star was already at that time, which allows simultaneous transmission of spider predators with their prey insect.

The ability of orb webs, to absorb the impact of flying led air attack insects spiders orbicularian dominant predators in many ecosystems. Insects and spiders have similar rates of diversification, which suggests that it is jointly issued, and the peak radiation occurred 100 Mya before the origin of angiosperms. More arachnid webs are vertical and spiders often hang upside down. Some are semi-Metepiera social and live in communal webs.


The true tissue Araneidae weaving with a sticky adhesive property and use Deinopoidea fibrils aqueous silk The Deinopoidea sticky and dry (including Uloboridae) have a cribellum - a flat surface, complex rotary disc, from which the tissue is released cribellate. The Araneoidea, or "ecribellate" Spiders do not have these two structures. The two families of orb-weavers are morphologically very different, but there are many similarities between your web form and web-design behavior. The cribellates preserve its traditional character, but was lost in escribellates cribellum.
