Those that help us are referred to as beneficial insects or just beneficials . Parasites are usually the immature stage of wasps and flies. The adult wasp or fly lays an egg in or on the egg or immature stage of the pest. The developing parasite usually feeds inside the pest and slowly destroys it. Predators are usually larger than parasites.
Predators actively seek and capture their prey.
They either eat the whole prey or suck out its body contents. A single predator will kill and eat many prey during its life. Common predators include adult and immature forms of lady bugs, immature lacewings, immature syrphid or hover flies, adult and immature assassin bugs, adult and immature damsel bugs, and some kinds of stink bugs. In addition, praying mantids, spiders and predatory mites are also predators. Attracting beneficials to your garden involves 3 main steps.
