When it comes to avoiding pushy suitors, female dragonflies have a trick up their wings—playing dead! This clever behavior, called thanatosis (or death-feigning), is their way of saying, "Not interested!" without having to say anything.

Caught in the Act

In a study published in Ecology, researchers observed female dragonflies putting on quite the performance. When a male dragonfly got too close for comfort, the female would suddenly drop out of the sky, hit the ground, and lie completely still, faking death until the would-be Romeo gave up and flew away.

A Survival Tactic

This behavior is most common in species where males are especially persistent in their mating attempts. By pulling the "I'm dead!" stunt, females save themselves the hassle, energy, and possible injury from unwanted advances.

Why It Works

Not only does this tactic help the ladies conserve their energy, but it also protects them from interference when they’ve already mated and are carrying fertilized eggs.
