One of the best ways to control pests in your garden is to encourage their natural enemies. Planting pollen and nectar plants, and providing protection for these beneficial insects, is a basic tenet of organic gardening, and a way to further increase the ecological diversity of your yard. I have listed the most common beneficial insects along with tips on attracting them to your yard.
Top 10 Good Insects in Your Garden
The familiar round, orange spotted ladybug is just one of more than 400 species of lady beetles found in North America. Most ladybug adults and larvae feed on aphids and other soft-bodied insects. Adults are attracted to flower nectar and pollen, which they must eat before they can reproduce.
Pale green or brown lacewing adults have distinctive large, veined wings and feed mainly on flower nectar. Lacewing larvae, however, are voracious predators that feed on aphids, thrips, scales, moth eggs, small caterpillars and mites.
Hover Flies aka Flower Flies or Syrphid Flies
Adults look like small bees with striped abdomens; the grayish or greenish slug- like larvae have pointed heads. Flower flies are attracted to flowers to feed on nectar and pollen. The larvae feed on aphids in tight places where other good bugs can’t go, and are especially helpful in early spring, before other beneficial insects are active. Flower flies also pollinate strawberries and raspberries, producing larger fruits and higher yields.
Including minute pirate bugs, ambush bugs and assassin bugs (soldier bugs, big-eyed bugs). These bugs prey on many insects, including tomato hornworms, thrips, spider mites, many insects’ eggs, leafhopper nymphs, corn earworms and other small caterpillars. Pirate bugs are attracted by willows, buckwheat, corn and nectar and pollen from many flowers. Predatory bugs are attracted to bunch grasses, shrubs and other permanent plantings that provide them shelter. A unique lure is available to attract emerging soldier bugs to gardens.
Large, long-legged, shiny blue-black or brown beetles that hide under rocks and logs during the day, and are fast-moving when disturbed. They feed on slugs, snails, cutworms, root maggots, and Colorado potato beetle larvae. Attract them by providing perennial ground covers, stones, or logs. Rove beetles resemble earwigs without pincers, and feed on many insect pests and like similar conditions to ground beetles.
Hunting and Parasitic Wasps
There are hundreds of species of wasps, including many that are so tiny you can barely see them. These mini-wasps often attack the eggs of pests, and are one of the most important insect groups that provide control of garden pests. They can be attracted by growing by pollen and nectar plants.
All spiders feed on insects and are very important in preventing pest outbreaks. The spiders normally found in gardens do not move indoors, nor are they poisonous. Permanent perennial plantings and straw mulches will provide shelter and dramatically increase spider populations in vegetable gardens.
Although they look similar to house flies, tachinid flies are very important enemies of cutworms, armyworms, tent caterpillars, cabbage loopers, gypsy moths, sawflies, Japanese beetles, squash bugs, and sowbugs. Grow pollen and nectar plants to attract them.
There are more than 80 species of dragonflies. They can be identified by their long narrow body, their large compound eyes and the four transparent wings.
There is variation in color. Sizes range from one to two inches.
The larvae are found in water. They eat mosquitoes, aphids and other pest bugs. Dragonflies have decreased considerably in abundance as the wetland areas where they live have dramatically decreased.
Want dragonflies? Don’t fill in that marshy area. Better yet, enlarge it, or dig your own pond.
Honeybees are important pollinators of many plants. Adults measure 2/3 inch long and are fuzzy, with gold-and-black striped bodies and transparent wings. Honey bees can often be identified by the balls of yellow pollen they carry on the backs of their legs.
Grow flowering plants. Encourage wild honey bees.
Because the spread of mites has seriously reduced honey bee populations, the wild honey bees that are left are even more important. Fun fact Pollinators are estimated to be worth $8 billion to our economy!
Many other insects are pollinators as well.
