A classic circular form spider's web Infographic illustrating the process of constructing an orb web. 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.
Caerostris sexcuspidata, also known as the common bark spider, is a species of spider that occurs in Southern Africa, and on islands off the east coast of Africa, such as Madagascar, the Comores and Aldabra Island. [1] It is a mainly nocturnal orb-web spider, the female constructing a large orb web stretching between trees or shrubs.
The Araneoidea, or the "ecribellate" spiders, do not have these two structures. The two groups of orb-weaving spiders are morphologically very distinct, yet much similarity exists between their web forms and web construction behaviors. The cribellates retained the ancestral character, yet the cribellum was lost in the escribellates.
The Woman with the Spider's Web (or The Woman with the Spider's Web between Bare Trunks, German: Die Frau mit dem Spinnennetz zwischen kahlen Bäumen) is a small c. 1803 print by the German Romantic painter Caspar David Friedrich, made into a woodcut the same year by his brother Christian Friedrich, a carpenter and furniture maker.
Within the spider’s social group, all spiders in the group take part in web construction, maintenance, and prey capture. [3] Nests are large web structures composed of a compact combination of silk and nearby branch or desert brush. These nests are built in spiny bush twigs or trees close to the ground at a height of 0.5 to 1.5 meters high. [10]
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. 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).

Peter Forsskal discovered Cyrtophora citricola in the Arabian Peninsula during his Yemen expedition, sometime between 1761 and 1763. [3] He first saw the spiders in citrus trees and described their horizontal webs as nets. The spider's common name, "tropical tent-web", derives from these observations. [4]
