Male vs. Female butterflies: How to tell them apart by size, colour, behaviour, and more

Butterflies exhibit striking differences between males and females, a phenomenon called sexual dimorphism. These variations, impacting size, colour, behaviour, and lifespan, are driven by evolutionary pressures for reproduction and survival. Males often display brighter colours for courtship, while females are typically larger and more camouflaged for egg-laying, highlighting nature’s remarkable adaptability.
