Insects display different colors for several key purposes. Warning coloration, also known as aposematism, helps dangerous or toxic insects warn predators to stay away – like the bright yellow and black of wasps. Camouflage coloring helps insects blend into their environment to avoid predators.
Some insects use colors for mate attraction, where bright colors help them find breeding partners. Others have evolved mimicry patterns to look like more dangerous species. The coloring comes from:
- Pigments in their exoskeleton
- Structural colors from light refraction
- Specialized scales and hairs
- Bioluminescence in some species
