摘 要：In aggressive mimicry,a predator accesses prey by mimicking the appearance and/or behavior of a harmless or beneficial model in order to avoid being correctly identified by its *** crab spider genus Phrynarachne is often cited as a textbook example of masquerading as bird droppings(BDs)in order to avoid ***,Phrynarachne spiders may also aggressively mimic BDs in order to deceive potential *** date,there is no experimental evidence to support aggressive mimicry in masquerading crab spiders;therefore,we performed a field survey,a manipulative field experiment,and visual modeling to test this hypothesis using Phrynarachne *** compared prey-attraction rates among BDs,spiders,and control empty leaves in the *** found that although all prey combined and agromyzid dipterans,in particular,were attracted to BDs at a higher rate than to spiders,other dipterans and hymenopterans were attracted to BDs at a similar rate as to *** spiders and BDs attracted insects at a significantly higher rate than did control *** predicted,prey was attracted to experimentally blackened or whitened spiders significantly less frequently than to unmanipulated ***,visual modeling suggested that spiders and BDs can be detected by dipterans and hymenopterans against background leaves,but they are indistinguishable from each *** together,our results suggest that insects lured by spiders may misidentify them as BDs,and bird-dropping masquerading may serve as aggressive mimicry in addition to predator avoidance in ***.
