“…Finally, there is a prominent interaction between prey availability and tolerance of conspecifics: spiders show greater tolerance of their neighbours at high levels of prey abundance (e.g. Riechert, 1981; Gillespie, 1987) and some spiders increase their tendency to hunt in groups and to increase group size when hunting larger prey items compared to smaller ones (Fernandez Campón, 2007).…”

Foraging theory was first developed to predict the behaviour of widely-foraging animals that actively search for prey. Although the behaviour of sit-and-wait predators often follows predictions derived from foraging theory, the similarity between these two distinct groups of predators is not always obvious. In this review, we compare foraging activities of trap-building predators (mainly pit-building antlions and web-building spiders), a specific group of sit-and-wait predators that construct traps as a foraging device, with those of widely-foraging predators. We refer to modifications of the trap characteristics as analogous to changes in foraging intensity. Our review illustrates that the responses of trap-building and widely-foraging predators to different internal and external factors, such as hunger level, conspecific density and predation threat are quite similar, calling for additional studies of foraging theory using trap-building predators. In each chapter of this review, we summarize the response of trap-building predators to a different factor, while contrasting it with the equivalent response characterizing widely-foraging predators. We provide here evidence that the behaviour of trap-building predators is not stereotypic or fixed as was once commonly accepted, rather it can vary greatly, depending on the individual's internal state and its interactions with external environmental factors.

“…The foraging behavior of the social spider can be described as the cooperative movement of the spiders towards the food source position. The spiders receive and analyze the vibrations propagated on the web to determine the potential direction of a food source [12]. We utilize this natural behavior to perform optimization over the search space in SSA.…”

A c c e p t e d M a n u s c r i p tWe propose a new nature-inspired social-spider-based swarm intelligence algorithm. We introduce a new social animal foraging model into meta-heuristic design. We introduce the design of information loss to handle pre-mature convergence. We perform a series of benchmark simulations to demonstrate the performance. We investigate the impact of control parameters on optimization results. AbstractThe growing complexity of real-world problems has motivated computer scientists to search for efficient problem-solving methods. Metaheuristics based on evolutionary computation and swarm intelligence are outstanding examples of nature-inspired solution techniques. Inspired by the social spiders, we propose a novel Social Spider Algorithm to solve global optimization problems. This algorithm is mainly based on the foraging strategy of social spiders, utilizing the vibrations on the spider web to determine the positions of preys. Different from the previously proposed swarm intelligence algorithms, we introduce a new social animal foraging strategy model to solve optimization problems. In addition, we perform preliminary parameter sensitivity analysis for our proposed algorithm, developing guidelines for choosing the parameter values. The Social Spider Algorithm is evaluated by a series of widely-used benchmark functions, and our proposed algorithm has superior performance compared with other state-of-the-art metaheuristics.

“…Higher levels of sociality under lower prey conditions is opposite to what has been reported for other social species (Avile ´s 1997; Uetz & Hieber 1997). In addition, despite differences in prey levels between habitats, fitness-related traits (number of eggs per sac) are similar in the two habitat types (Ferna ´ndez Campo ´n 2005). Differences in group capture and feeding of prey could result from genotypic adaptation to local environment, phenotypic plasticity or genetic differences in the level of plasticity between populations.…”

“…Populations of the orb-weaving spider Parawixia bistriata occupying habitats with high versus low prey availability differ in elements of their foraging behaviour (Ferna ´ndez Campo ´n 2007). Individuals from wet habitats with high prey levels have a lower tendency to engage in group prey capture, while spiders from dry habitats with lower prey availability have a higher tendency to engage in collective prey capture.…”
