They are capable of limiting and equilibrating pest populations (Nyffeler, 1999; Sunderland and Samu, 2000), because of their abundance and high predatory potential (Tahir and Butt, 2009), prey specialization, polyphagy, top-down effect, numerical and functional responses, and wasteful killing (Maloney et al.
