← Insects are scared to death of fish

The nature of the "stress" might be bettter understood by a combination of determining whether it is the sight or smell of the predator that affects the insect's life. My bet is that it is the smell, because that could be toxic. I doubt that it is mere sight, because insects probably don't have enough neurons to get worried about things. Repeating the experiment with the fish hidden from view, but not from smell, would help. Of course, even if it is only smell that matters, any direct toxicity effect has to be determined, because the smell alone might be enough to "worry" the insect, if it is capable of getting worried.
