Quick Answer
Male peacock spiders use vivid colors and dance-like displays to attract females. The display helps females assess species identity and mate quality.
The Full Story
Peacock spiders are tiny Australian jumping spiders famous for elaborate courtship. Males raise colorful abdominal flaps and perform precise leg waves and body vibrations to impress females. The bright patterns and movements help signal that the male is the correct species and possibly a strong mate. Because these spiders are tiny, visual display is surprisingly important in courtship. Their dances are among the most colorful examples of sexual selection in arachnids.
