生活在非洲干湿季节环境中的双环蝶属蝴蝶表现出明显的季节性多表型。本文描述了在季节交替的进化反应背景下表型可塑性的例子，其中一个季节有利于生长和繁殖，而另一个季节是应激环境，限制了幼虫的生长和成虫的生存。季节性形式反映了不同的成虫表型，包括形态（翅膀模式）和生活史特征。这些性状的遗传和生理耦合涉及到一个共同的激素系统的调解。最后，我表明这些蝴蝶翅膀上的眼斑图案也为研究波动不对称的机制及其与环境压力的相互作用提供了潜力。
Butterflies of the genus Bicyclus inhabiting wet-dry seasonal environments in Africa express striking seasonal polyphenism. This paper describes this example of phenotypic plasticity in the context of an evolutionary response to alternative seasons, one of which is favourable for growth and reproduction while the other is a stress environment, limiting in terms of larval growth and adult survival. The seasonal forms reflect alternative adult phenotypes which involve both morphological (wing pattern) and life history traits. The genetic and physiological coupling of these traits involves mediation by a common hormonal system. Finally, I show that the eyespot patterns on the wings of these butterflies also offer potential for studying the mechanisms of fluctuating asymmetry and its interactions with environmental stress.
