N2 - Nuptial feeding can evolve as sensory traps where the male exploits the female's foraging motivation in a sexual context. The nuptial prey gift of the nursery-web spider Pisaura mirabilis is wrapped in white silk, and it has been suggested that males initially exploit the maternal care instinct by producing a nuptial gift that resembles the female's eggsac. In mating experiments we examined whether males exploit the female's foraging motivation or the female's maternal care instinct. We carried out a gift-switching experiment, where males presented an eggsac, a wrapped fly or an unwrapped fly as nuptial gifts. Females fed on eggsacs as well as on prey gifts. Mating success was similar for males with both wrapped and unwrapped gifts, indicating that wrapping per se does not increase male mating success.
