More Plant Security Countermeasures
I've talked about plant security systems, both here and in Beyond Fear. Specifically, I've talked about tobacco plants that call air strikes against insects that eat them, by releasing a scent that attracts predators to those insects. Here's another defense: the plants also tag caterpillars for predators by feeding them a sweet snack (full episode here) that makes them give off a strong scent.
