Male Dragonflies Are Gullible 

Biologist Rassim Khelifa has discovered some fascinating behavior exhibited by female dragonflys:

[H]e happened to notice one dragonfly chasing another—suddenly, the one being chased simply stopped flying and crashed to the ground, belly up. The pursuer, he notes, paused for a moment, then moved on. As Khelifa approached the dragonfly on the ground he noted it was female and then was surprised when she suddenly awoke, turned over and flew away.

Crashing to the ground, mid-flight, is some impressive acting.
