Prey interception drives web invasion and spider size determines successful web takeover in nocturnal orb-web spiders [PDF]
A striking feature of web-building spiders is the use of silk to make webs, mainly for prey capture. However, building a web is energetically expensive and increases the risk of predation. To reduce such costs and still have access to abundant prey, some

Effect of spider’s weight on signal transmittance in vertical orb webs [PDF]
Spider orb web is a sophisticated structure that needs to fulfil multiple roles, such as trapping prey and transmitting web-borne signals. When building their web, heavier spiders tend to increase the pretension on the web, which seems counterintuitive ...

Observations on web-invasion by the jumping spider Thyene imperialis in Israel (Araneae: Salticidae) [PDF]
Observations on Thyene imperialis (Rossi, 1846) in Israel, Negev desert, invading a web of Cyclosa deserticola Levy, 1998 are reported. The female leapt into the orb-web to catch Cyclosa spiders.

Spider orientation and hub position in orb webs [PDF]
Orb-web building spiders (Araneae: Araneoidea, Uloboridae) can be considered as territorial central place foragers. In territorial central place foragers, the optimal foraging arena is circular, with the forager sitting in its centre.

Cyclosa Menge, 1866 (Araneidae) Orb‐Weavers Build Stabilimenta That Resemble Larger Spiders [PDF]
Orb‐weaving spiders are known to create stabilimenta—silk situated at particular locations of the web. While anecdotal reports and popular media have long suggested that some spiders arrange debris in their webs to resemble a larger spider, this behavior

Geometric regularity in webs of non‐orb‐weaving spiders
Geometric regularity of spider webs has been intensively studied in orb‐weaving spiders, although it is not exclusive of orb weavers. Here, we document the geometrically regular, repetitive elements in the webs of the non‐orb‐weaving groups Leptonetidae ...

Behavioural analysis of web building anomalies in the orb-weaving spider Zygiella x-notata (Araneae, Araneidae) [PDF]
Among animal constructions, spider’s orb webs represent regular geometrical architecture models. Their construction is the result of successive, simple and reproducible behavioural patterns, often considered as stereotyped.

Spatial learning affects thread tension control in orb-web spiders. [PDF]
Although it is well known that spatial learning can be important in the biology of predators that actively move around in search for food, comparatively little is known about ways in which spatial learning might function in the strategies of sit-and-wait predators. In this study, Cyclosa octotuberculata , an orb-web

Imperfections in perfect architecture: The orb web of spiders [PDF]
Among animal constructions, the orb webs of spiders are perfect geometrical architectural models. Webs are constructed by means of a succession of behaviours, which are often considered as instinctive and stereotyped.

Junctional microstructure of the non-sticky spiral scaffold in the golden orb web spider, Trichonephila clavata [PDF]
The non-sticky spiral silk, which typically serves as a temporary structural component in most orb-weaving spiders, functions as a permanent scaffold in the golden orb-web spider (Trichonephila clavata).
