The diverse color pattern of insects are products of natural/sexual selection and affect their survival and reproductive success. Therefore understanding the function of the color patterns is critical to understand their life-history traits such as defensive/territorial behavior or mating strategies. However how we (humans) see and perceive their colors does not reflect the true nature of the insect colors because the insect colors have evolved to work best for the appropriate receiver. For example, defensive coloration have evolved to deceive predators’ eyes, and sexual traits of males have evolved to attract the eyes of the conspecific females. The visual system (therefore the perception of color, too) substantially differ between species and it is important to consider the appropriate receiver’s point of view (visual system) to properly understand the functional aspect of insect color pattern. Here I introduce the concepts of visual modelling of animals’ point of view to study insect coloration and present a case study research on camouflage of moths.
