Beneficial Garden Insects

Did you know that there are beneficial garden insects that will help you with your gardening? I do not like bugs but my husband is always telling me not to kill them outside unless I know what I am doing.

So what bugs are good for the garden? How do they help? What do they look like?

First, and probably the most recognizable is the Ladybug. As children, we are taught the nursery rhyme "Ladybug, Ladybug, fly away home." The familiar red-orange bugs with black spots seem to be everywhere. Adult ladybugs and their offspring, called larvae, eat the leaf-destroying bugs known as aphids.

Ladybugs are good for your garden. They are beneficial insects.

Ground beetles are known for being shiny and are either brown or bluish black. They eat snails and slugs so you want them in your garden. They also partake of root maggots, cutworms, and the larvae of the Colorado potato beetle.

Rove beetles enjoy killing mites and snails. We get a lot of snails in our backyard.

Wasps like to eat the eggs of plant-harming insects. Most of us can recognize wasps and know to move out of their way so we don't get stung. We have so many wasps in our backyard during the spring and summer that I am sometimes fearful to go out there. I always want to spray them, but my husband will not let me as they are so good for our plants.

Spiders are creepy beneficial garden insects. They eat other insects, many of which like to destroy your plants so you need them in your garden. If you happen to see poisonous spiders, they are not beneficial insects so get rid of them before they bite you.

Houseflies are not good for your garden but a fly who looks almost like them is good for the garden, the Tachinid fly.

I hate houseflies. I am almost convinced that they wait right outside our backdoor and fly in as soon as it opens. Houseflies are not good for your garden but a fly who looks almost like them is good for the garden, the Tachinid fly. They love to kill squash bugs, sowbugs, cabbage loopers, tent caterpillars, gypsy moths, cutworms, armyworms, and Japanese beetles.

Spined soldier bugs are your friends because they feed on gypsy moth caterpillars and the larvae of plant-harming beetles like the Mexican bean beetle.

Pirate bugs or flower bugs, also known as Anthocoridae, eat small insects and their eggs by making a hole in their prey, putting their saliva into them and then drinking everything inside the prey. Nasty! But they do save your garden plants from spider mites, thrips, and corn earworms.

Other good predatory bugs include the ambush bug and the big-eyed bug. They also eat caterpillars and insect larvae that will destroy your plant leaves.

Ambush bugs will eat caterpillars and insect larvae that will destroy your plant leaves.

Hover flies, also known as syrphid flies or flower flies are also good for your garden. They actually pollinate both raspberries and strawberries. We grow lots of strawberries each year so we are happy to have hover flies in our garden. They look like small bees with black and yellow stripes so you may think they are bees. Their larvae eat aphids so you want to welcome them into your garden. Aphids will destroy your plant leaves.

Lacewings are also beneficial garden insects. They are green with delicate-looking wings with holes in them, resembling lace. Their larvae look scary and ugly.  They are brown with small bits of yellow on them and they have legs. When you see them, do not destroy them because the larvae eat thrips, aphids, moth eggs, caterpillars, mites, and scales.
