Scientists used to describe insects as not having a central brain, making it difficult to imagine how insects could be conscious. But recent research suggests that subjective experience could be more widespread in the animal kingdom than we realize.
MELBOURNE – Last summer, a cabbage white butterfly laid its eggs on an arugula I was growing. Before long, the plant was swarming with green caterpillars, well disguised against the green leaves. I had other arugula plants, some distance away, that would give me plenty of leaves for our salads, and I didn’t want to use an insecticide, so I just left the caterpillars alone. Soon, every leaf was eaten down to the stalk. With nothing left to eat, the caterpillars, not ready to begin the next stage of their life cycle, all starved to death.
