An Opposite Pattern to the Conventional Thermal Hypothesis: Temperature-Dependent Variation in Coloration of Adults of Saccharosydne procerus (Homoptera: Delphacidae)
Melanism is a common polymorphism in many insect species that also influences immune function.

In this study, the links among environmental temperature, melanism, and PO activity of Saccharosydne ...

Different color morphs may have distinct life history traits, e.g., development time, growth rate, and body weight.
