Jumping Spider Shake Down

Studio 360

The courtship displays of male jumping spiders in the family Salticidae combine a number of flashy signals to woo females. Displaying males might shake their mouthparts, bob their abdomens, wave their legs, dance from side to side, and flash bright colors. In addition to their crazy dance moves, males will simultaneously generate vibrational signals that can be detected by the female. Vibrations are produced by rubbing different body parts together (like the head and abdomen) or by tapping the ground with a leg, mouthpart, or abdomen. Watch closely, and you can see how some of their movements correspond to the vibrations they’re making while dancing.

To see these spiders in action, watch the Science Friday video “Shake Your Silk-Maker: The Dance of the Peacock Spider

Spider Song and Dance Challenge

Using a selection of dances and vibrational signals—recorded by graduate student Madeline B. Girard, who’s researching peacock spiders—we’ve created a challenge: try to match each spider’s courtship display with the vibration signals that it produced while dancing. Post your guesses in the comments box below, and have fun!
