Abstract. Caching or storing surplus prey may reduce the risk of starvation during periods of food deprivation. While this behaviour occurs in a variety of birds and mammals, it is infrequent among invertebrates. However, golden orb-web spiders, Nephila edulis, incorporate a prey cache in their relatively permanent web, which they feed on during periods of food shortage. Heavier spiders significantly reduced weight loss if they were able to access a cache, but lost weight if the cache was… 

Frequency, composition and variation in external food stores constructed by orb-web spiders: Nephila edulis and Nephila plumipes (Araneae : Araneoidea)

Field experiments indicated that the presence or absence of external stores in the web of N. plumipes had no influence on mortality, weight gain, or the presence of Argyrodes kleptoparasites, suggesting that the storage band in N. edulis has other, non-food-storing functions.

Nephila clavipes spiders (Araneae: Nephilidae) keep track of captured prey counts: testing for a sense of numerosity in an orb-weaver

Nephila clavipes golden orb-web spiders accumulate prey larders on their webs andSearching increased with prey quantity (larder size) and did so more steeply with higher prey counts than with single prey of larger sizes, suggesting that the spiders seem to track prey quantity in two ways, but to attend more to prey numerosity.

Web-building spiders attract prey by storing decaying matter

The Y-maze olfactometer data reveal an entirely novel foraging strategy, in which a sit-and-wait predator attracts insect prey by utilising the odours of decaying organic material.

Memory of prey larders in golden orb-web spiders, Nephila clavipes (Araneae: Nephilidae)

It is suggested that N. clavipes form memories of the size of the larders they have accumulated, and that they use those memories to regulate recovery efforts when the lARDers are pilfered.

Kleptoparasites influence foraging behaviour of the spider Stegodyphus lineatus (Araneae, Eresidae)

Results suggest that Stegodyphus lineatus adapt its web-building behaviour in response to the risk of kleptoparasitism, and there was a tendency for spiders that were exposed to ants to build larger webs.

Food storage and carrion feeding in the fiddler crab Uca lactea

Food hoarding is an adaptive strategy that enhances survival and reproductive success in food-scarce environments. It has been assumed that food hoarders, especially vertebrates, have the ability to

Food storage and carrion feeding in the fiddler crab Uca lactea

Empirical evidence is provided that food storage in aquatic invertebrates is dependent on the availability of food and semilunar intertidal rhythms, and that females may increase their reproductive effort by storing food.

Convergence between a mosquito-eating predator's natural diet and its prey-choice behaviour

These findings illustrate the importance of going beyond simply specifying preferred prey categories when characterizing predators as ‘specialized’ and a need to make clear conceptual distinctions between a predator's natural diet, the prey categories that are relevant to the predator, and the predator's prey-choicebehaviour.

Argiope bruennichi shows a drinking-like behaviour in web hub decorations (Araneae, Araneidae)

The data suggest that hub decorations of A. bruennichi might have an adaptive significance by helping to maintain a balance of water metabolism, adding yet another element to the spirited debate about the functional significance of web decorations.

Multiple structures interactively influence prey capture efficiency in spider orb webs



Alternative foraging modes of orb web weaving spiders

This work shows that orb weaving spiders forage differently and that different patterns of web use have resulted in at least two very different, but equally effective, means of prey capture, and predicts that for small spiders prey are abundant and small spiders tolerate high rates of web breakdown.

Feeding experience affects web relocation and investment in web threads in an orb-web spider, Cyclosa argenteoalba

It is suggested that spiders minimize their investment in web threads until they are certain that the web site is prey rich, and use previous experience of prey capture at a web site to decide whether to relocate their web.


No difference in survivorship was observed between fed spiders and those left to natural prey capture, and spiders receiving supplemental prey relocated their webs less frequently than those spiders that wer e unsupplemented.

Web damage and feeding experience influence web site tenacity in the orb-web spider Argiope keyserlingi Karsch

For orb-web spiders, the decision to remain at a particular site or to relocate elsewhere will ultimately depend on the quality of the site. In the past, the quality of the site has been measured in

Spider effects on prey: tests for superfluous killing in five web-builders

Though an assemblage of predatory species is not a necessary condition of equilibrium point control, the presence of numerous spider species exhibiting varied foraging strategies, phenologies, and sizes significantly augments the limiting influences spiders might have on prey populations over what a single spider species would have.

Food Storability and the Foraging Behavior of Fox Squirrels (Sciurus niger)

Future value of food affects the foraging behavior of squirrels through the balancing of present and future needs, and some properties of caching in the context of a food's future value are explored.

Feeding patterns, habits and food storage in Pilumnus vespertilio (Brachyura: Xanthidae)

Female crabs had higher daily and monthly stomach fullness indices compared with the male crabs and the utilization of stored food material was remarkably higher in females than in males, especially during the reproductive period.

Attack behavior of diguetid spiders and the origin of prey wrapping in spiders

A webliving spider is more likely to “encounter” a new, partially subdued prey while handling another than is a webless spider.

The ecology and behavior of Nephila maculata : a supplement

Analysis of data on the web-site constancy of Nephila maculata shows that this spider may, as an adult, spend considerable periods at one site, possibly as an antipredator device, and observations show that birds may learn to avoid contact with large araneid webs.

The material cost and stickiness of capture threads and the evolution of orb‐weaving spiders

Differences in the thread economy and the total stickiness of webs constructed by spiders of different weights suggest that adhesive orb-weavers should grow more rapidly and be capable of attaining a larger size than cribellate orb- weavers.
