Abstract Predation on earthworms is common in some generalist predator species, as for example several ground beetle species (Coleoptera: Carabidae) that frequently feed on earthworms. In spiders (Araneae), however, such behavior is far less well documented. A survey of reports on spiders feeding on earthworms yielded a total of 44 naturally occurring predation events. Spiders from 14 families were observed feeding on earthworms in nature, and species from two additional families consumed… Expand
Spiders (Arachnida: Araneae) feeding on snakes (Reptilia: Squamata)
Abstract. In this paper, 319 incidents of snake predation by spiders are reported based on a comprehensive global literature and social media survey. Snake-catching spiders have been documented fromExpand
Beyond polyphagy and opportunism: natural prey of hunting spiders in the canopy of apple trees
It is concluded that arboreal hunting spiders forage selectively and consume a large number of apple pests; however, spiders’ beneficial effects are greatly reduced by their high levels of intraguild predation and by a propensity to switch from pests to alternative prey. Expand
Spiders as frog-eaters: a global perspective
The finding that such a high diversity of spider taxa is utilizingsuch a high variety of frog taxa as prey is novel is novel and the utilization of frogs as supplementary food increases the spiders' food supply, and this is presumed to enhance their chance of survival. Expand
Black widow spiders, Latrodectus spp. (Araneae: Theridiidae), and other spiders feeding on mammals
The success of widow spiders in subduing small mammals can be explained by their ability to spin strong webs made up of tough silk, and producing a very potent toxin specifically targeting the vertebrate nervous system. Expand
Different groups of ground‐dwelling spiders share similar trophic niches in temperate forests
The results suggest that feeding frequency of spiders is affected by predator body size and by selection of certain prey type, suggesting that including small species and juveniles provides a more comprehensive picture of food web organization. Expand
Predation of Phidippus sp [Araneae: Salticidae] on Nilaparvata lugens [Hemiptera: Delphacidae] at different densities
Phidippus sp. (Araneae: Salticidae) is often found in rice field and has potency as the natural enemy of Nilaparvata lugens (Hemiptera: Delphacidae). The study aimed to know the predation ofExpand
Record breaking achievements by spiders and the scientists who study them
A list of 99 record breaking achievements by spiders, compiled in a world-record style format, to provide an entryway for teachers and students—as well as scientists themselves—into the biology of spiders (the “Spider World Records”). Expand


Predation on amphibians by spiders (Arachnida, Araneae) in the Neotropical region
Herein, we report observations about spider predation on anurans (adults and juveniles) in Central Amazonia and a literature review of spiders preying on amphibians in the Neotropical zoogeographicExpand
There seems to be a consistent trend of greater diet breadth of the hunters compared to the web-weavers in agroecosystems, and diet breadth computed with the Inverted Simpson Index was, on average, significantly higher in the hunting spiders than the web spiders. Expand
Plant-eating by spiders
Abstract Spiders, a group of predominantly insectivorous predators, occasionally use plant food to supplement their insect prey. In the current review, we tracked down 95 reported incidents ofExpand
A vertebrate-eating jumping spider (Araneae: Salticidae) from Florida, USA
Vertebrate predation by salticid spiders has not been previously documented in the scientific literature and female as well as male P. regius were engaged in feeding on this type of vertebrates. Expand
Diet Composition and Significance of Earthworms as Food of Harvestmen (Arachnida: Opiliones)
Feeding trials conducted with female harvestmen revealed that these arachnids were not capable of subduing live earthworms, suggesting that consumption of these in the field might be limited to scavenging. Expand
A house spider was observed, filmed and photographed while feeding on an earthworm, an extensive search in the literature revealed that several arachnologists had noted spiders feeding on earthworms, altogether in 11 different families. Expand
Fish Predation by Semi-Aquatic Spiders: A Global Pattern
It is provided that fish predation by semi-aquatic spiders is geographically widespread, occurring on all continents except Antarctica, and that fish prey might be an occasional prey item of substantial nutritional importance. Expand
Diet and foraging behaviour of huntsman spiders in the Namib dunes (Araneae: Heteropodidae)
Diet and foraging behaviour of three species of burrowing huntsman spiders from the Namib dunes were investigated over a three-year period, finding that Namib huntsmen are sit-and-wait predators within narrow territories waiting for the fortuitous arrival of prey and are thus unlikely to limit prey populations.

This work critically evaluates contemporary evolutionary hypotheses that might be used to explain the evolution of specialised foraging in predators, and proposes a unifying concept within which four types of trophic categories are defined using ecological (diet breadth) and evolutionary contexts.

Bat Predation by Spiders
Evidence suggests that spider predation on flying vertebrates is more widespread than previously assumed. Expand
