蜘蛛躲藏在花丛,它藉拟态躲避鸟类猎食,等待猎物到来。帝王斑蝶(Danaus plexippus,左)与总督蝴蝶(Limenitis archippus,右)在视觉上相似,而帝王斑蝶对鸟类捕食者来说有毒且气味难闻,但总督蝴蝶则否,鸟类捕食者会同时避免接触它们,这是一个拟态的例子。由 Henry Walter Bates 制作的图片展示了袖粉蝶属物种(顶行,第三行)和各种绡蝶族物种(蛱蝶科,第二行,底行)之间的贝氏拟态。伪装现象发生于Ctenomorphodes chronus这种竹节虫物种之中,使该物种个体在视觉上与桉属物种的枝条相似。
贝氏拟态(Batesian mimicry,以英国博物学家亨利·沃尔特·贝兹(Henry Walter Bates)命名),于1861年在林奈学会发表论文,说明亚马逊河的粉蝶会模仿毒蝶属,保护自己免于被捕食,一个物种拟态模仿另一个成功的物种,显得有毒或者是无食用价值。但该拟态并不会攻击掠食者。例如,一种鹿子蛾会拟态成为黄胡蜂,但它并不能螫。但掠食者还是会把它当成黄胡蜂回避。例如尺蠖形态及行为与树枝或茎相仿,藉以躲避猎食。
