There are both harmful and beneficial insects in every garden. Nothing in nature is superfluous or accidental. Did you know that there are thousands of insects in a yard, but only about a tenth of them are pests? Most are either harmless, useful and even necessary. Beneficial insects fall into three main categories:
Pollinators – they are absolutely necessary. For example, without bees we could not exist! Butterflies, flies and moths are also in this category. They work to pollinate the flowers in the garden.
Predators – they are pretty much useful, as they eat harmful insects. Predators are: ladybugs, mantises and green lace larvae.
Parasitizers – parasites grow from other insects. They lay their eggs in others’ bodies, and their larvae feed on host insects. Such are the parasitic wasps.
