The List of Useful Insects

Overall, most people aren't big fans of bugs and all their creepy, crawly legs and squirmy, squishy bodies, but while there are many insects worthy of our fear and loathing, there are plenty of useful insects that we should be celebrating. In fact, many beneficial garden insects actually improve soil, pollinate plants or kill off nasty insects that harm plants.

The List of Useful Insects

Some useful insects include honey bees, ladybugs, praying mantises, green lacewings, dragonflies and earthworms.

Helpful Honey Bees

Bees are perfect examples of insects that people fear and try to kill even though they are actually incredibly helpful. While nobody likes being stung by bees, we all enjoy the many plants they pollinate.

If you looked up a most helpful farm insects list, honey bees would almost certainly be on the top. In fact, bees are considered to be the most important pollinator on the planet, spurring Albert Einstein to speculate that "if the bee disappeared off the surface of the globe then man would only have four years of life left. No more bees, no more pollination, no more plants, no more animals, no more man."

It's said that bees contribute more than $20 billion to the value of crop production in the United States, pollinating plants such as apples, cranberries, blueberries, cherries, melons, almonds and broccoli. Of course, they also provide honey in addition to helping to pollinate our plants.

Lovely Little Ladybugs

One of the most famous of all helpful insects is the lovely ladybug, also known as ladybirds or lady beetles. In fact, these little guys are so revered that even those who are terrified of most insects still find spotted ladybugs to be charming. It's no wonder that aside from their cute looks, they are also great for gardens, and they eat pesky aphids, whiteflies and other insects that destroy plants. In fact, a ladybug can eat up to 5,000 aphids in its lifetime.

Proud Praying Mantises

It's easy to be intimidated by praying mantises given that they look creepy and that you probably know that the females are known to eat the heads off of their mates. That being said, they're actually great garden insects, as they are skilled predators that can instantly snag and kill garden pests such as grubs, aphids, grasshoppers, crickets, flies and more.

Great Green Lacewings

Green lacewings may not be as famous as ladybugs, but they are also great hunters of pests such as aphids, thrips, mealybugs, small caterpillars, mites and whiteflies as well, eating them both as larvae and adults. The mother lacewings lay eggs among the larvae of whitefly and aphid colonies, and the lacewing starts eating these pests from birth. They are aggressive predators, but if you want to help them, it's important to keep ants away from your garden since ants eat the eggs of lacewings.

Beautifully Daring Dragonflies

Dragonflies are like ladybugs in that many insect haters still appreciate their beauty. They are also easy to love because they prey on pesky flying insects including mosquitoes, flies, moths, whiteflies and fruit flies. They also eat the larvae of these creatures, stopping them before they can cause damage.

Squirmy Old Earthworms

Yes, earthworms aren't much to look at, but they are incredibly beneficial, improving the soil wherever they go. Their excrement enriches soil and controls its pH. As if that's not enough, their tunnels aerate the dirt, allowing water to reach the roots of plants more easily. The more earthworms there are in soil, the better its quality.
