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 ...
Deinopidae, also known as net casting spiders, is a family of cribellate [ 1] spiders first described by Carl Ludwig Koch in 1850. [ 2] It consists of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed ...
The web of a funnel-web spider Tegenaria duellica. Many spiders, but not all, build webs. Other spiders use a wide variety of methods to capture prey. Web: There are several recognised types of spider web. Spiral orb webs, associated primarily with the family Araneidae; Tangle webs or cobwebs, associated with the family Theridiidae; Funnel webs,
186 genera, 3108 species. Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", [ 1] hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs ...
In the Karakamia woodland area, 50 kilometers (31 miles) away from the zoo, the team collected more two-dimensional orb webs from Araneidae and Phonognathidae spider families.
When prey becomes caught in the web, the spider may undulate the web back and forth to further trap the insect. When the prey is secure, the spider kills it by injecting its venom and then wraps the prey in a cocoon of silk for later consumption (typically 1–4 hours later).
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]
Pisaurina mira. ( Walckenaer, 1837) [ 1] Pisaurina mira, also known as the American nursery web spider, due to the web it raises young in, is a species of spider in the family Pisauridae. They are often mistaken for wolf spiders ( Lycosidae) due to their physical resemblance. P. mira is distinguished by its unique eye arrangement of two rows.
