If you have a chance to play in nature, if you are
sprayed by a beetle, if the color of a butterfly wing comes off on your fingers, if you watch a caterpillar spin it's cocoon - you come away with a sense of mystery and uncertainty.

beetles that were unable to release chemicals: The scientists got the
beetles to prerelease their
spray by tugging on their legs so that once they were swallowed, they would be chemically defenseless against the toads.
