Beans that can summon other predators in self defense







Lima beans (Fabaceae: Phaseolus lunatus L) has a very interesting way in which it responds to various predatory attacks. The mechanisms are fascinating. For instance when the beans are under attack from spider mites, they release chemicals to attract natural predators of the mites as well as warn nearby plants. Amazingly, if the plants are damaged by an agricultural tool or, say, a wayward cow, they emit different stress signals that are ignored by their neighbors.

An extensive study done on this particular species can be found by clicking the links below.

Some say he’s half man half fish, others say he’s more of a seventy/thirty split. Either way he’s a fishy bastard.
