...However, some studies suggest that grouping actually contributes to the individual foraging success by the ‘ricochet effect’ (Uetz, 1989; Lubin et al., 2001): the capture of prey items after they were slowed and weakened by several webs in succession....

...Shadow competition occurs when one sit-and-wait predator can catch the moving prey before it encounters other predators (Linton et al., 1991), and this has also been documented in spiders (Lubin et al., 2001)....

...Exploitation also increases with density in its special form of ‘‘shadow competition’’ (one TB predator catches the moving prey before it encounters other predators; e.g. Wilson, 1974; Lubin et al., 2001; Rao, 2009)....

...In high density groups, only peripheral individuals 11 can forage successfully, but in low density groups, some prey items reach the group 12 centre (Lubin et al. 2001)....

...Simulation of predation risk and foraging gains 17 Previous authors have modeled how predation risk and foraging gains change as a 18 function of the distance from the centre of a group (Linton et al. 1991; Bumann et al. 19 1997; Lubin et al. 2001)....
