适应性辐射和收敛的过程，通常被认为是宏观进化的一个特征，可以在南美洲Heliconius属范围内的蝴蝶的模仿颜色图案中看到。这可以通过根据成虫、蛹和幼虫的形态将该属划分为亚群来证明：物种之间的模仿仅仅是由密切的系统关系引起的理论因此被驳斥，因为同一形态组的成员可以表现出广泛不同的模仿模式，相反，相互模仿可能属于几个不同的形态组。各种形式的平行和趋同进化被认为可以解释目前的拟态模式，这个过程甚至在完全的物种形成之前就已经开始了。一个新的亚属（聂鲁达）被创建包含三个非典型成员的属。
The process of adaptive radiation and convergence, usually regarded as a feature of macro-evolution, can be seen in the mimetic colour patterns of the butterflies within the confines of the South American genus Heliconius. This can be shown by dividing the genus into subgroups on the basis of adult, pupal and larval morphology: the theory that the mimicry between species results solely from close systematic relationships is thereby refuted, as members of the same morphological group can display widely divergent mimetic patterns, and conversely mutual mimics may belong to several different morphological groups. Various forms of parallel and convergent evolution are thought to account for the present pattern of mimicry, the process is known to start even before full speciation has taken place. A new subgenus (Neruda) is created to contain three atypical members of the genus.
