在自然界中,生活着各种各样的动物,同时也生活着它们的天敌。在适应环境的长期演变中,不少动物的形态色泽和花纹与栖息藏身处的物体,十分相似,能有效地活动、觅食和逃避敌害。动物的这种“隐身”法,叫做拟态。自然界物体中很多昆虫有与植物相似的拟态。有一种松天蛾幼虫,背上从头到尾的淡绿色和深绿条纹,粗看就象松树的松针。巴西的刺虫停在有刺的树木上,活象树上长出的一枚尖刺。头上长角的角蝉,如果栖息在一棵有刺的灌木上,酷肖一枝假刺。在印度,有一种甲虫外形与色泽,跟苔藓 In nature, various animals live and their natural enemies live. In adapting to the long-term evolution of the environment, many animals’ morphologies, colors and patterns are similar to the objects inhabiting their hiding places and can effectively move, feed and escape predators. This “stealth” method of animals is called mimetic. Many insects in nature have similar mimicry of plants. There is a larvae of the pine hawk moth, with pale green and dark green stripes from head to tail on the back and thick pine needles. Brazilian thornbugs stop on barbed trees and look like a spike that grows on a tree. A horned horned owl on its head, if it inhabits a thorny shrub, the cool squish has a fake thorn.
