Grasshopper vs. Parasitic Worm

The parasitic worm wins this fight with a grasshopper, but what's interesting is how the worm wins. Apparently, it brainwashes the grasshopper into a suicide death dive. No joke. From Cynical-C.

A parasitic worm that makes the grasshopper it invades jump into water and commit suicide does so by chemically influencing its brain, a study of the insects’ proteins reveal.

The parasitic Nematomorph hairworm (Spinochordodes tellinii) develops inside land-dwelling grasshoppers and crickets until the time comes for the worm to transform into an aquatic adult. Somehow mature hairworms brainwash their hosts into behaving in way they never usually would – causing them to seek out and plunge into water.
