True or false – the only good bug is a dead bug? FALSE! Without bugs (mostly insects), our world would not be the same. There are more than 1.5 million known insect species in the world, with about 97 percent being either good for the garden, or simply benign. Less than three percent of insects do actual damage to plants. Beneficial insects perform vital functions in the environment – pollinating plants, eating harmful bugs, and breaking down dead materials to help begin the process of recycling, among them.
