Insects display various colors for several key purposes. Warning coloration helps dangerous or toxic insects ward off predators – like the bright yellow and black of wasps. Camouflage coloring helps insects blend with their environment to avoid detection.
Colors also play important roles in:
- Mating displays to attract partners
- Temperature regulation (darker colors absorb more heat)
- UV protection from sun exposure
Insect colors come from two main sources: pigments that absorb and reflect specific light wavelengths, and structural colors created by microscopic surface features that scatter light, like the iridescent wings of butterflies.
