AI Article Synopsis

  • Insects use colors for various purposes like mating signals, avoiding predators, and regulating body temperature.
  • Climate change may alter melanin-based colors in insects, affecting their physiological functions and interactions with other species.
  • This review aims to summarize existing knowledge on how climate-induced color changes impact insect biology, focusing on environmental influences, adaptive mechanisms, and their consequences for interactions with both the same and different species.

Article Abstract

The colours of insects function in intraspecific communication such as sexual signalling, interspecific communication such as protection from predators, and in physiological processes, such as thermoregulation. The expression of melanin-based colours is temperature-dependent and thus likely to be impacted by a changing climate. However, it is unclear how climate change drives changes in body and wing colour may impact insect physiology and their interactions with conspecifics (e.g. mates) or heterospecific (e.g. predators or prey). The aim of this review is to synthesise the current knowledge of the consequences of climate-driven colour change on insects. Here, we discuss the environmental factors that affect insect colours, and then we outline the adaptive mechanisms in terms of phenotypic plasticity and microevolutionary response. Throughout we discuss the impact of climate-related colour change on insect physiology, and interactions with con-and-heterospecifics.
