Insects display various colors for several important biological reasons. The main purposes include:
- Warning coloration (aposematism) – Bright colors like red, yellow, and orange warn predators of toxicity
- Camouflage – Earth tones and green colors help insects blend with their environment
- Mate attraction – Vibrant colors can help attract potential mates during breeding season
- Temperature regulation – Darker colors absorb more heat, helping insects warm up
These colors come from two main sources: pigments that absorb and reflect different wavelengths of light, and structural colors created by microscopic structures that reflect and scatter light, like the iridescent wings of butterflies.
