Bugs We Like

Creating a thriving garden is about more than just planting flowers and shrubs. It's also about fostering a healthy ecosystem. One of the best ways to do this is by attracting beneficial insects. These tiny allies can help keep pest populations in check, ensuring your garden remains vibrant and healthy.

Why Beneficial Insects Matter

A diverse garden supports various beneficial insects, including lacewings, ladybugs, and dustywings. These insects are nature's pest controllers. By providing layers of trees, shrubs, annuals, and perennials, you create a welcoming environment for these valuable predators. A diverse landscape encourages biodiversity, which is essential for a balanced ecosystem.

The Most Useful Beneficial Insects

Among the most effective beneficial insects are lacewings (both green and brown), ladybugs, and dustywings. Each plays a unique role in maintaining the health of your garden.

Green Lacewings

Green lacewing adults are familiar to many gardeners. Their delicate, mint-green wings blend seamlessly into the foliage. Although they are primarily nocturnal and often arboreal, they can be attracted in numbers to porch lights. The smaller brown lacewings are harder to spot and are not yet available for purchase in gardens. Many species of brown lacewings specialize in certain plants, making them unique predators. Ladybugs are also crucial, as they help control populations of insects that feed on plants. They are particularly known for their insatiable appetite for aphids. Dustywings, though often mistaken for whiteflies, are tiny predators that can also benefit your garden.

Green Lacewings: Nature's Pest Control

You might spot green lacewings and snakeflies visiting blossoms during the day. Depending on their species, lacewings prey on various arthropods, including aphids, scale insects, whiteflies, mealybugs, spider mites, and even small caterpillars. Some species can detect leafminer larvae and pierce leaves to reach their prey.

Brown Lacewings: The Unsung Heroes

Although smaller and less colorful, brown lacewings are easily recognized by attentive gardeners. They lay their eggs singly on leaves or bark, often in tree habitats. Their larvae resemble those of green lacewings but have less prominent mandibles. Both adults and larvae of brown lacewings are important predators of homopterans like scale insects, aphids, and whitefly nymphs. They have long lifespans, high reproductive rates, and voracious appetites.

Ladybugs: Your Garden's Best Friends

Ladybugs can be a gardener's salvation. They can consume up to 5,000 aphids in their lifetime! Besides aphids, they also help eliminate other soft-bodied insects like mites, mealybugs, and leafhoppers, as well as insect eggs and even ants. Interestingly, ladybugs are beetles, not true bugs, and not all of them are female.

If you plan to buy ladybugs for your garden, here are some tips for a successful release. Keep them refrigerated until you're ready to release them. They may be dehydrated when you purchase them, so mist them with water before putting them in the refrigerator. Avoid releasing them during the day, as they will fly away immediately. Instead, release them at dusk or early morning. Before releasing, spray a fine mist of water on the plants with aphids and place the ladybugs at the base of those plants.

Dustywings: The Tiny Predators

Dustywings can often be found in ornamental purple-leaved plums, although they are frequently mistaken for the disruptive whiteflies. However, dustywings can be distinguished by their wing position at rest; whiteflies hold their wings much flatter. This tiny tree-dwelling predator has a taste for spider mites, scale insects, and arthropod eggs. More common than previously thought, dustywings are primarily found in warmer parts of the Pacific Northwest. Despite their usefulness, they are not commercially available.

The Threat of Aphids

Aphids can wreak havoc on your favorite plants, including hibiscus and roses. These pests can quickly multiply and damage your garden. That's where beneficial insects come into play. By attracting lacewings and ladybugs, you can naturally control aphid populations and protect your beloved plants.

Creating a Welcoming Environment for Beneficial Insects

To attract these helpful insects, consider the following tips:

1. Plant a Variety of Flowers: Choose plants that bloom at different times throughout the growing season. This ensures a continuous food source for beneficial insects.

   
   

2. Provide Shelter: Incorporate layers of trees and shrubs to create habitats for these insects. They need places to hide and lay their eggs.

   
   

3. Avoid Pesticides: Chemical pesticides can harm beneficial insects. Opt for organic gardening methods to protect your garden's allies.

   
   

4. Create Water Sources: A shallow dish of water or a small pond can provide hydration for beneficial insects.

   
   

5. Encourage Biodiversity: A diverse garden attracts a wider range of beneficial insects. Plant native species to support local ecosystems.

   
   

Conclusion

In conclusion, beneficial insects like lacewings, ladybugs, and dustywings play a crucial role in maintaining a healthy garden. By creating a welcoming environment, you can attract these helpful allies and keep pest populations in check. Remember, a diverse garden is a thriving garden. So, let's work together to cultivate a beautiful and balanced landscape!
