The horsehair worm starts life as an egg laid in a puddle.  The puddle dries out and a grasshopper comes along and eats the egg, which promptly hatches and burrows through the gut of the insect into its body cavity.  Here, the insect grows until it reaches adulthood. At that point it starts producing chemicals which take over the brain of the insect and cause the insect to seek out water, which it jumps into.  The worm then exits the hopper and lives in the puddle, mating and laying more eggs.  The grasshopper, if it doesn't drown, may survive the ordeal.
