SummaryBecause of the large amount of webbing they provide, social spider colonies often host other satellite spider species referred to as kleptoparasites or food stealers. Such kleptoparasites may take advantage of increased prey capture rates associated with large spider aggregations. This study investigated the relationship between a cooperatively social spider species, Anelosimus eximius (Araneae: Theridiidae), which lives in the undergrowth of tropical rainforests in Peru, and its… 

Effect of Kleptoparasitic Ants on the Foraging Behavior of a Social Spider (Stegodyphus sarasinorum Karsch, 1891).

The experiments suggested that the web building behavior of S. sarasinorum was influenced by the exposure to ants, however, exposure to ant caused no significant effect in the prey capture, handling time of prey and prey ingestion behaviors of the spider.

State-dependent prey type preferences of a kleptoparasitic spider Argyrodes flavescens (Araneae: Theridiidae)

This is the first study to show that Argyrodes spiders alter their foraging tactics depending on hunger level, prey type, or the presence of the host, and may maximize their energy gain and minimize predation risk in different circumstances.

Effects of host colony size and hygiene behaviours on social spider kleptoparasite loads along an elevation gradient

This study opens up social spiders as a novel system in which to study how host characteristics inter act with environmental factors to affect parasite loads and suggests a role for colony‐level metabolism in determining ecological patterns in parasitism.

A New Independently Derived Social Spider with Explosive Colony Proliferation and a Female Size Dimorphism 1

A redescription and phylogenetic analysis corroborate the placement of this species in Theridion, indicating that sociality has evolved independently in at least three theridiid genera.

Opportunistic Egg Feeding in the Kleptoparasitic Spider Argyrodes gibbosus

In Sicily, Argyrodes gibbosus parasitizes webs of the spider Cyrtophora citricola, a facultative colonial species, and the exploitation of this new resource could ensure rapid development for the kleptoparasite which was characterized by the presence of larger females and a higher mating rate.

ARGYRODES: PHYLOGENY, SOCIALITY AND INTERSPECIFIC INTERACTIONS—A REPORT ON THE ARGYRODES SYMPOSIUM, BADPLAAS 2001

It is concluded that Argyrodes forms a monophyletic group within the Theridiidae, and that there are clear monophyletsic clades within the genus (already identified as species groups) that appear to share behavioral characteristics.

The Communal Lifestyle of Web-Building Spiders in Tropical Forests

Most web-building spiders build their webs solitary, and they usually prevent other individuals from invading their webs. However, some web-builders make their webs communally, and these are found

FORAGING VERSATILITY AND THE INFLUENC E OF HOST AVAILABILITY IN ARGYRODES TRIGONU M (ARANEAE, THERIDIIDAE)

Overall, A. trigonum behaved predominantly a a host predator; however, kleptoparasitism is more likely in host webs that last longer .

BROOD PARASITISM AMONG SPIDERS: INTERACTIONS BETWEEN SALTICIDS AND DIGUETIA MOJAVEA

The results suggest that these salticids are obligate brood parasites of D. mojavea and provide one of the first experimental examples of host–parasite coupling among arthropods.

Collective Defense of Aphis nerii and Uroleucon hypochoeridis (Homoptera, Aphididae) against Natural Enemies

Obs observations of natural aphid colonies revealed that a collective twitching and kicking response (CTKR) was frequently evoked during oviposition attempts of the parasitoid wasp Aphidius colemani and during attacks of aphidophagous larvae, suggesting that visual signals in combination with twitching-related substrate vibrations may play an important role in synchronising defense among members of a colony.

Kleptobiosis in Spiders

It is assumed that foraging strategies, as different as they may be, all have in common that costs are cut while calory intake is optimized and structural support becomes the limiting resource for web spiders.

Predation by Argyrodes (Theridiidae) on Solitary and Communal Spiders

Observations of spider predation by two species of Argyrodes, A. fictilium and A. trigonum, support the view that predation on other spiders is more important than kleptoparasitism for some temperate ArgyROdes.

The effect of kleptoparasitism on prey consumption and web relocation in a Peruvian population of the spider Nephila clavipes

There was a complete correlation between the number of Argyrodes individuals in a spider's web and the percentage of those spiders that relocated their web, which indicated that N. clavipes that moved their webs shortly after observation had consumed significantly fewer prey items than those that maintained their web site.

Prey Capture and Feeding in the Social Spider Anelosimus eximius

Wild colonies of the social spider Anelosimus eximius (Araneae, Theridiidae) appear often to be food-limited and not all females come to reproduction, and a first analysis of the participation in prey capture and ingestion is attempted.

The existence of a less—than—optimal behavior within the egret's foraging repertoire suggests that, under circumstances other than those studied, it might contribute to foraging optimization.

Arms races between and within species

The arms race concept is suggested to help to resolve three long-standing questions in evolutionary theory: one lineage may drive the other to extinction, one may reach an optimum, thereby preventing the other from doing so, and both sides may reach a mutual local optimum.
