A spider web, spiderweb, spider's web, or cobweb (from the archaic word coppe, meaning 'spider') [1] is a structure created by a spider out of proteinaceous spider silk extruded from its spinnerets, generally meant to catch its prey. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber ...
Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting and ...
The spider's web occupies a unique biological niche: "They build their web with the orb suspended directly above a river or the water body of a lake, a habitat that no other spider can use". [4] This position allows the spiders to catch prey flying over the water, with webs observed containing up to 32 mayflies at a time. [2]
The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before a final spiral of sticky capture silk.
The spider web of T. versicolor, like any other orb weaver spider, is used to catch prey. It can be seen as an extension of the spider's senses. It can be seen as an extension of the spider's senses. The orb web is efficiently made with a minimum amount of silk (0.1–0.5 mg of silk) in a short amount of time (30–60 minutes).
