To protect against herbivores, the wild tobacco plant deposits trichomes, sweet treats irresistible to but also potentially fatal for leaf-eating caterpillars. Shortly after ingesting the trichomes, the insect releases a particular odor that attracts ground-foraging predators. “What Plants Talk About” premieres Wednesday, April 3 at 8/7c on PBS (check local listings). (Video limited to US & Territories).
