蝴蝶通常表现出适应性表型可塑性，在早期阶段的环境线索被用来产生一个表型，最大限度地提高成人所经历的环境中的适应性。许多热带satyrine蝴蝶（蛱蝶科：satyrine）是季节性的多型和生产不同的湿季和旱季形式的成年人提供紧密的环境表型匹配的季节性环境。在旱季表现的旱季型可以在实验室中通过在低温下或在劣质食物上生长幼虫来诱导。由于这两个因素也往往会降低幼虫的生长速度，幼虫的生长速度可能是一个内部的线索，翻译成表型的表达的环境线索。如果是这种情况，我们预测生长较慢的幼虫更有可能发展出旱季表型。为了验证这一假设，我们测量了幼虫的生长速度和成人的表型（眼斑大小和翅膀形状）的个人共同的晚上棕色蝴蝶（Melanitis leda），饲养在不同的温度和各种寄主植物物种。我们发现，在治疗中，幼虫生长速度较低（低温，特定的宿主植物）更有可能发展旱季表型（小眼斑，镰刀形翅尖），但在治疗中，幼虫的生长速度主要与翅形，而不是眼斑大小。这些关系往往是男性比女性更强的男性表现出更广泛的眼点大小和翅膀形状。总体而言，只有可塑性的翅膀形状似乎是（部分）介导的幼虫生长，并在性别特异性的方式。
Butterflies often show adaptive phenotypic plasticity where environmental cues during early stages are used to produce a phenotype that maximizes fitness in the environment experienced by adults. Many tropical satyrine butterflies (Nymphalidae: Satyrinae) are seasonally polyphenic and produce distinct wet- and dry-season form adults providing tight environment-phenotype matching in seasonal environments. Dry-season forms, which are expressed in the dry season, can be induced in the laboratory by growing larvae at low temperatures or on poor food quality. Since both these factors also tend to reduce larval growth rate, larval growth rate may be an internal cue that translates the environmental cues into the expression of phenotypes. If this is the case, we predict that slower-growing larvae would be more likely to develop a dry-season phenotype. To test this hypothesis, we measured both larval growth rate and adult phenotype (eyespot size and wing shape) of individuals of the common evening brown butterfly (Melanitis leda), reared at various temperatures and on various host-plant species. We found that among treatments, larvae with lower growth rates (low temperature, particular host plants) were more likely to develop dry-season phenotypes (small eyespots, falcate wing tips), but within treatments, larval growth rate was mainly linked to wing shape, not eyespot size. These relationships tended to be stronger for males than females as males showed a wider range of eyespot sizes and wing shapes. Overall, only plasticity in wing shape appears to be (partly) mediated by larval growth, and in a sex-specific manner.
