The effect of predation risk on spider's decisions on web-site relocation

TLDR
Spiders that received simulated predator stimuli relocated more often on the day after treatment than did spiders that were not exposed to predator stimuli, indicating that spiders estimated futurepredation risk from their predator-encounter experience and responded to perceived increase in predation risk at current site by abandoning their web site upon web-rebuilding.

Signals for damage control: web decorations in Argiope keyserlingi (Araneae: Araneidae)

TLDR
Adult St. Andrew's Cross spider females subjected to substantial web damage both reduced the size of subsequent webs and increased investment in web decoration size, consistent with an advertising role of web decorations.

Multiple structures interactively influence prey capture efficiency in spider orb webs

Body-colour variation in an orb-web spider and its effect on predation success

TLDR
It is shown that darker spiders have a greater chance of capturing prey than silver spiders and that the bright silver colour does not function to attract prey in C. argenteoalba, indicating that body-colour variation affects predation success among individuals.

Plasticity in extended phenotypes: orb web architectural responses to variations in prey parameters

  • S. Blamires
  • Environmental Science
    Journal of Experimental Biology
  • 2010
TLDR
The nutrient concentrations of cockroaches, and adult and juvenile crickets were analyzed to devise experiments that controlled prey protein concentration while varying prey size, ingested mass, energy concentration and feeding frequency of the orb web spider Argiope keyserlingi, and it was found that A. keyserlingsi alters overall architecture according to feeding frequency.

Evidence of bird dropping masquerading by a spider to avoid predators

TLDR
The orb-web spider Cyclosa ginnaga's decoration and body colouration forms a bird dropping masquerade, which reduces its probability of predation.

Estimating the repeatability of memories of captured prey formed by Frontinella communis spiders (Araneae: Linyphiidae)

TLDR
This work used the behaviour of Frontinella communis spiders after removal of prey from their webs as an assay of the contents of their memories of the prey, finding significant repeatability in the spiders’ searching behaviour, suggesting repeatable in memory content.

Animal Camouflage: The multiple disguises of spiders

TLDR
This chapter aims at a broad exploration of the literature pertinent to the subject of spider camouflage, from web colour and decorations, body colour to movement, and evoke physiological and ecological hypotheses for colour change.

Spider webs: Evolution, diversity and plasticity

TLDR
It is argued that that this underappreciated aspect of spider biology renders them superior models for studies investigating behavioural plasticity at the individual level.

Effects of resource availability on the web structure of female western black widows: is the web structure constrained by physiological trade-offs?

A major challenge of biological research is to understand what generates and maintains consistent behavioral variation among animals. Time and energy trade-offs, where expressing one behavior is

Signalling conflict between prey and predator attraction

TLDR
St. Andrew’s Cross spiders apparently resolve the conflicting nature of a prey‐ and predator‐attracting signal by varying their decorating behaviour according to the risk of predation: spiders spun fewer decorations if their webs were located in dense vegetation where predators had greater access, than if the webs were Located in sparse vegetation.

Signaling by decorating webs: luring prey or deterring predators?

TLDR
Investigation of the effects of spider decoration and coloration on insect interception rates of webs built by Argiope aemula and whether presence of decorations may decrease predation risk of spiders shows that the signals conveyed by decorations can visually lure prey but at the cost of an increasedpredation risk.

Spiders Use Airborne Cues to Respond to Flying Insect Predators by Building Orb‐Web with Fewer Silk Thread and Larger Silk Decorations

TLDR
Evidence is provided that orb-web spiders devote less effort to foraging in response to the presence of their predators, which is considered to reduce their foraging efficiency.

Do stabilimenta in orb webs attract prey or defend spiders

TLDR
It is shown that stabilimentum building is a defensive behavior, supporting the ‘‘web advertisement’’ hypothesis that the high visibility of stabilimenta can prevent birds from flying through webs and suggesting that much of the variation in stabilimentsa may be accounted for by a cost–benefit trade-off made when including stabilimento in webs.

Predator-induced plasticity in web-building behaviour

Prey detection without successful capture affects spider’s orb-web building behaviour

TLDR
The ability of spiders to obtain information from unsuccessful predation experiences was investigated by examining the effects on web building, a significant foraging investment, of prey detection without successful capture in the orb-web spider Cyclosa octotuberculata.

The influence of predator cues on orb-web spider foraging behaviour

TLDR
It is suggested that orb-web spider Argiope keyserlingi may use multiple cues to assess predation pressure and that they respond differently to predators based on past experience.

SIGNAL POLYMORPHISM IN THE WEB-DECORATING SPIDER ARGIOPE ARGENTATA IS CORRELATED WITH REDUCED SURVIVORSHIP AND THE PRESENCE OF STINGLESS BEES, ITS PRIMARY PREY

TLDR
The findings suggest that spider web decorating behavior is affected by conflicting selection pressures: the positive effect of prey attraction versus the negative effect of predator attraction.

SILK MEDIATED DEFENSE BY AN ORB WEB SPIDER AGAINST PREDATORY MUD-DAUBER WASPS

TLDR
It is suggested that stabilimenta may function to delay pursuit of spiders as they drop from webs by physically blocking wasps, camouflaging spiders or distracting attacking wasps.

Spiders that decorate their webs at higher frequency intercept more prey and grow faster

  • Psychology

  • 2005
TLDR
This is the first study to reveal a fitness consequence of decorating behaviour in spiders, and shows a strong positive relationship between the growth rate in terms of weight gain and the frequency of decoration-building, as well as the rate of insect interception.
