20.500.12556/DiRROS-20148 Jumping spider invades an orb web to prey on a resident male While surveying operational sex ratios of the giant golden orb weaver Nephila pilipes (Fabricius, 1793) in Singapore, we documented a stunning case of predatory behavior of a jumping spider Viciria pavesii Thorell, 1877. A female V. pavesii invaded a N. pilipes orb web that was occupied by the resident female and four males, and successfully captured, killed, and removed one of the Nephila males. Whether araneophagy in V. pavesii is opportunistic or a predatory ritual remains to be tested more precisely, but because the observed predatory event triggered an aggressive response by the N. pilipes alpha male, it is plausible that V. pavesii may engage in aggressive mimicry. We place our observation into the context of jumping spider cognition and behavioral tactics that are so far well understood only in a few spartaeine genera, notably Portia Karsch, 1878. Viciria Thorell, 1877, we argue, is another such jumping spider taxon worthy of behavioral scrutiny.
