蟹蛛（学名：Acrabisus onustus）是一种以花朵为猎物的蜘蛛，它们会伪装成花朵的颜色，这种策略被认为是欺骗鸟类捕食者和昆虫猎物的。但是，尽管这种模仿对人类观察者来说是显而易见的，但从未在不同的视觉系统中进行过研究。在这里，我们表明，当女性蟹蜘蛛模仿不同的花卉品种，他们同时神秘的颜色视觉系统的鸟类捕食者和hyperteran猎物。
Crab-spiders (Thomisus onustus) positioned for hunting on flowers disguise themselves by assuming the same colour as the flower, a strategy that is assumed to fool both bird predators and insect prey. But although this mimicry is obvious to the human observer, it has never been examined with respect to different visual systems. Here we show that when female crab-spiders mimic different flower species, they are simultaneously cryptic in the colour-vision systems of both bird predators and hymenopteran prey.
