Spatial learning affects thread tension control in orb-web spiders.

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 spider that uses its legs to contract radial threads of its web to increase thre...

Prey interception drives web invasion and spider size determines successful web takeover in nocturnal orb-web spiders

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 web-building spiders have evolved web invasion behaviour. In general, no consistent patterns of web invasion have emerged and the factors dete...

Quantitative analysis of orb web patterns in four species of spiders.

The orb webs of the four species Araneus pima (species nova), Araneus diadematus (Clerck), Argiope aurantia (Lucas), and Neoscona domiciliorum (Hentz) built under controlled laboratory conditions were compared and evaluated quantitatively at two different points in the life cycle in regard to size, regularity, shape, and fine structure. Orb webs of two species from one genus can be distinguishe...

The stability of hygroscopic compounds in orb-web spider viscous thread

Each of the droplets that form an orb-weaving spider’s viscous capture thread are composed of a viscoelastic glycoprotein glue core that is surrounded by an aqueous layer and supported by a pair of protein axial fibers. Low molecular weight organic and inorganic compounds within the aqueous layer confer droplet hygroscopicity, thereby maintaining the glycoprotein’s adhesion and extensibility an...

Herbivory in Spiders: The Importance of Pollen for Orb-Weavers

Orb-weaving spiders (Araneidae) are commonly regarded as generalist insect predators but resources provided by plants such as pollen may be an important dietary supplementation. Their webs snare insect prey, but can also trap aerial plankton like pollen and fungal spores. When recycling their orb webs, the spiders may therefore also feed on adhering pollen grains or fungal spores via extraoral ...
