When approaching prey, a stalking predator should consider trade-offs between the probabilities of early detection (by the prey, before the strike), spontaneous departure (of prey, before the strike), prey escape (following the strike) and interference (by rivals or predators). In this study we tested the response of a jumping spider, Plexippus paykullito a background with two different camouflaging properties, and two different prey types (maggots versus adult house flies). Spiders jumped… 
The influence of camouflage and prey type on predatory decisions of jumping spider
To test whether jumping spiders flexibly adapt their predatory behavior to camouflaging properties of the background and prey type, the behavior of Yllenus arenarius (Araneae, Salticide), a cryptically colored jumping spider hunting leafhoppers and caterpillars on two types of background was analyzed.
Predatory response to changes in camouflage in a sexually dimorphic jumping spider
Differences in approaching speed between males before and after final molt suggest a combined effect of background color and ontogenetic change of body coloration on the predatory decisions of these male spiders.
Hunting Prey With Different Escape Potentials—Alternative Predatory Tactics In A Dune Dwelling Salticid
Alternative prey-catching tactics of a dune-dwelling salticid Yllenus arenarius Menge 1868 indicate that Y. arenarius can not only distinguish between different types of prey, but can also employ specific tactics to catch them.
Exploitation of environmental noise by an araneophagic assassin bug
It was found that assassin bugs were more likely to catch the spider in the presence of wind and localized vibrations in the web, and this supports the hypothesis that noise-related timing of behaviour reflects decisions made as part of a predatory strategy, rather than responses to physical disturbance.
Alternative predatory tactics in a juvenile jumping spider
Various differences were found in the mode of catching the prey, which indicate that the juvenile Yllenus arenarius Menge 1868 possess a conditional hunting strategy.

Salticids are distinct for the develop of unique predatory strategies like Kleptoparasitism .Present paper deales with the interspecific kleptoparasitism , success rate and prey preference of jumping
Jumping spiders (Salticidae) are well known for their complex visual hunting behavior, but this is the first comparative study investigating their ability to catch prey in the absence of visual cues
Development of prey-specific predatory behavior in a jumping spider (Araneae: Salticidae)
Checking the influence of age and experience on pre-programmed predatory behavior and predatory success of Yllenus arenarius Menge 1868 found age-dependent changes occurred in four aspects of predation: direction of approach, mode of approach and distance of attack.
What determines the attack distance of a stalking predator
An optimization model of a stalking hunt based on a predator’s multi-stage decision-making incorporates the essential feature of stalking predation: as the predator attacks at a shorter distance and when it attacks before the prey notices it, its hunting success is enhanced.
Distance of approach to prey is adjusted to the prey ’ s ability to escape in Yllenus arenarius Menge ( Araneae , Salticidae )
The aim of the study was to investigate, whether Yllenus arenarius, a dune dwelling salticid, can adjust its jumping distance when hunting prey of high or low escapability risk. It was found that the


Predatory behavior of jumping spiders.
Salticids, the largest family of spiders, have unique eyes, acute vision, and elaborate vision-mediated predatory behavior, which is more pronounced than in any other spider group. Diverse predatory
A qualitative analysis of hunting behaviour in jumping spiders (Araneae: Salticidae).
The distance separating the spider from its prey is shown to be a determining factor in the establishment of a particular response pattern, and the effects of hunger and some other response control variables on hunting behaviour are considered.
Predatory behavior of the zebra spider, Salticus scenicus (Araneae: Salticidae)
The zebra spider (Salticus scenicus) orients towards prey detected by its lateral eyes whenever the angle subtended by such prey exceeds 5.5°, and the probable optimality of this behavioral tactic is discussed.
Use of prey‐specific predatory behaviour by North American jumping spiders (Araneae, Salticidae) of the genus Phidippus
Each species is shown to be a versatile predator which uses a different prey-specific prey-capture behaviour depending on whether prey is a fly or a caterpillar: spiders approached the two types of prey differently and leapt on them from different distances.
Conditional strategies and interpopulation variation in the behaviour of jumping spiders
Abstract Conditional strategies and interpopulation variation in the mating and predatory behaviour of salticid spiders are reviewed. A functional approach is adopted, and defended, in which
Predatory versatility and intraspecific interactions of spartaeine jumping spiders (Araneae: Salticidae): Brettus adonis, B. cingulatus, Cyrba algerina, and Phaeacius sp. indet.
Although they did not spin prey-capture webs, each of the four species moulted in a silken structure which crudely resembled a web, each was a highly eucryptic, sedentary ambushing specialist that sat on tree trunks and lunged downward on passing insects.
