Good Garden Bugs: They're biological pest control at its finest.
In this case, these really are the 10 Most Wanted in your backyard.
What's that you say? No such thing as a good insect? The only good insect is a dead one?
Nah. These good guys eat the bad bugs.
So if you kill off the good guys,
you're going to have twice as many bad guys on your hands (and your
plants). This is all natural pest control at its best.
Here are the 10 good bugs you'll want to find and keep at home in your backyard, along with a brief description of why each is a beneficial addition to your plants:
Earthworms till the soil by tunneling through it as part of their everyday routine. These tunnels allow air and moisture to pass easily through the soil, creating a healthy environment for plants to grow.
These creatures don't stop there: After digestion, earthworms produce excrement about the size of a pin head that improves the properties of the soil, such as porosity and moisture retention, and helps in the fight against pests and diseases.
I call them "poopers".
Pillbugs actually aren't really bugs at all: they're land-based crustaceans.
These creatures are the best kind of scavengers, as they feed on dead or decaying matter. They return nutrients to the soil when they defecate.
They are also beneficial because they circulate the soil without eating plants.
Dung beetles are small, dark-colored beetles that are usually shiny, brown or black and sometimes have a metalic-blue or purple luster.
They benefit your garden by feeding on and disposig of fungi, decaying organic matter, dung and other organic materials. (Hence the name.) They're extremely important in the natural cycle of the breakdown of organic matter in the soil.
Bumble bees are friendlier than honeybees and only sting if they've been really molested or roughly handled. They don't swarm, like honeybees, nor attack like wasps.
They're important pollinators of plants and vegetables because they have longer tongues so they can pollinate plants with deep flowers.
In the world of biological pest control weapons, praying mantises are howitzer cannons. They're among the few nocturnal hunters able to catch and eat moths. You want this good guy hanging out around your plants.
Although moths themselves aren't garden pests, their larvae can decimate an entire plant in a matter of days.
Did I mention they come with a delightful added benefit built in? They love to eat roaches.
Eat bad pests.
Lacewing larvae preys on aphids, leafhoppers, mites, psyllids, thrips, whiteflies and the eggs of insects.
The larvae's huge appetites make them a very important player in the pest control arena if your backyard plants include flowers, fruits, or vegetables.
You can attract these beneficial bugs with wildflower plants and pollen-producing flowers.
Ladybugs control pests that pester your plants. Definitely a good bug to have.
They are capable of consuming up to 60 aphids per day, but will also eat a variety of other insects and larvae including scales, mealy bugs, leaf hoppers, mites, and various types of soft-bodied insects.
They may be white, yellow, pink, orange, red or black, and usually have spots.
Eat aphids and other pests.
Braconid wasps are parasitoids: parasites which usually kill their hosts.
And, they like to feed on things we don't like on our plants: hornworms, caterpillars, aphids, squash bugs and stink bugs.
The Braconidae family of bugs consider these to be gourmet delicacies.
Butterflies are pretty to look at. But this good guy is much more than a pretty face to your plants.
When an adult butterfly lands on a flower to suck some delicious nectar through its proboscis, it accidentally gathers pollen on its body as it rubs against the anther. The butterfly rubs some of the pollen on the next flower it moves to and collects some more. Through this process, the butterfly is able to pollinate numerous flowers as it moves along. Pollination allows plants to reproduce by producing seeds.
Wasps are beneficial predators. They hunt insects such as white flies and aphids. They kill caterpillars; a nest of fall webworms can provide ample meat.
For many, wasps are seen as a threat and even a nuisance, but they perform vital roles in the eco-system. As a natural form of pest control, they are a gardener's friend, taking crop-eating insects to feed to their young.
They also pollinate flowers and other plants.
