The caterpillar of the Manduca Moth (Manduca sexta) feeds on leaves of the tobacco plant. The toxic nicotine stored in the leaf hairs accumulates in the body of the caterpillar without harming it. This makes it inedible for most enemies. If the attack with Manduca caterpillars gets to a certain point, the plant sends out chemical messengers attracting a species of bugs that kill and feed on the caterpillars.
