Coexistence Of Plant And Insect Species

A predator--a stink bug (Pentatomidae)--feeds on a monarch caterpillar (Danaus plexippus) while on a milkweed plant (Asclepias syriaca). Although plants face an endless onslaught of attack by herbivores, they are not alone. By feeding on herbivores, predatory insects also protect plants. Scientists are studying these organisms as part of their research on the community and evolutionary ecology of interactions between the milkweed plant and the insect herbivores that prey upon it.
