Video: Jumping spider seduction

September 13, 2016

Every day, right under our noses, tiny jumping spiders engage in elaborate acts of synchronized seduction. These courtship rituals are one area of focus in Associate Professor Damian Elias’s lab. Male jumping spiders dance to win the acceptance—and avoid the jaws—of picky potential mates. And to enhance their dance, the males provide their own multi-instrumental accompaniment—personal vibratory songs that they create through lightning-fast movements of their legs and abdomens.


Elias, an evolutionary biologist, has made it his life’s work to understand the breadth and complexity of these spider serenades, which, until recently, were impossible to perceive by human senses. Armed with spider decoys, high-speed cameras, and laser listening devices that allow him to act, see, and hear like a spider, Elias and his colleagues are discovering what combination of ability, grace, and swagger allows jumping spiders to discern which individuals offer the best potential in a mate. And they’re finding that these dances may in fact play a critical role in the evolution and differentiation of new jumping spider species.
