Passage Summary: It is strange that an endangered dragonfly does better in areas where its natural predator, the red devil crayfish, lives.

Reasoning: Red devil crayfish prey on the larvae of the endangered Hine's emerald dragonfly, yet dragonfly populations are healthier in areas where these crayfish are present.

Analysis: To resolve this paradox, we need to find a way for the predator to actually benefit the prey's population overall. Perhaps the crayfish eat something else that is even more dangerous to the dragonflies, or maybe they provide a benefit to the habitat that outweighs the predation. Look for an answer that introduces a third variable explaining why the presence of the 'enemy' is actually a net positive for the dragonfly's survival.
