Ladybugs are some of the most useful insects in your garden. As they develop, ladybugs begin their lifecycle from eggs. These eggs then hatch into larvae. The larvae stage of the lady gub is the most useful to a gardener. This is because these semi-developed insects feed on the most destructive pests, aphids. In fact, a single ladybug larva can feed on 4oaphids in one hour.

Green Lacewings

These insects are useful to plants in two ways:

  • Adult green lacewings feed on nectar and pollen, and in the process, they transfer pollen. They also help in the critical process of cross-pollination.
  • These insects also lay their eggs on these plants, hatching them into useful larvae. Their larvae resemble a slug/an alligator, and they feed on soft-bodied pests such as aphids and caterpillars.

Praying Mantises

The praying mantis is a fierce predator. It preys on grasshoppers and any other insects it comes across in your garden. Also, keep in mind that the mantis will also kill useful insects such as butterflies, bees, and other praying mantises as it feeds on harmful insects.


Spiders are small bugs that do not fall under the classification of insects because of their body structure. Spiders are indeed arachnids, and they help in controlling pests in your garden. They are most useful because they trap live insects, killing them. Unfortunately, due to their poisonous bites, you may not encourage them in your garden.

As a result, they help in pollination, more so where cross-pollination is essential. Additionally, hoverfly larvae are vicious predators feeding harmful pests such as aphids, thrips, beetles, and caterpillars. A hoverfly larva kills insects by sucking the juice from their bodies.

Parasitic Wasps

These are small types of wasps whose activity may be invisible. Despite their size, these insects are very useful in your garden. Let us look at the different types of parasitic wasps and their work.

Braconid wasps; are a group of parasitic wasps that lays eggs on the backs of caterpillars and tomato hornworms. Their eggs form white cocoons on the back of the affected insects. Once the larvae hatch, they feed on the host killing it. The larvae also develop into more wasps that continue taking care of these harmful parasites.

Trichogramma wasps; are also other forms of parasitic wasps which work similarly to braconids above. However, they lay eggs on other insects such as grasshoppers, caterpillars, Mexican bean beetles, and squash bugs. Indeed, this type of insect is known to take care of over 200 garden pests.

Big Eyed Bug

This is another useful bug that kills harmful insects in your gardens, such as aphids and caterpillars. It attacks and kills these insects when they least expect and sucking their bodies dry. They are also attracted to cosmos, fennel, mint, marigolds, and goldenrod.

Adult butterflies are quite useful to your garden as they help in facilitating pollination. A butterfly develops through stages whereby an adult lays eggs that develop into a caterpillar, pupa, a chrysalis, and then a butterfly. The host plant of the insect acts as shelter and food to the developing young one to maturity. Butterflies generally feed on nectar and plant and fruit sap.


These are some of the most useful organisms to your gardens. They are not insects but a different class of organisms that live in the soil. Earthworms help fertilize the soils in the following ways:
