What would you do if you were one of 1,500 brothers and sisters born at the same time? If you were a baby spider, the answer would be simple: spin a silk "balloon" and ride the wind away! Please allow me to drop some knowledge on you in honor of Ride the Wind Day.
"Ballooning" or "kiting" is a method of air borne dispersal used by spiders to move between locations. After emerging from the egg sac, spiderlings will engage in this behavior to reduce competition and increase genetic diversity. After all, sharing the same space with hundreds of your closest relatives could lead to problems more serious than just a little sibling rivalry! Ballooning isn't limited to spider babies, but spiders weighing more than 1 milligram are likely to have trouble defying gravity. Spiders also face the risk of death while flying, so adults are less likely to engage in this behavior.
