Lacewings are delicate insects recognized by their transparent wings covered with a network of fine veins. Green lacewings are among the most familiar species found in gardens. Adults are often pale green, while their larvae have elongated bodies and strong jaws adapted for catching small insects.

Lacewing larvae are particularly valuable natural predators. They commonly feed on aphids, insect eggs, mites, mealybugs, scale insects, and other soft-bodied pests. Because of their feeding habits, lacewings can help reduce pest populations and are frequently considered useful insects for biological pest management.

A common problem is misidentification of lacewing larvae. Their unusual body shape and active movements can make them look like pests to inexperienced gardeners. If an unfamiliar insect is found near aphid colonies, examine it carefully before removing it, as it may be helping control the infestation.

Encourage lacewings by maintaining flowering plants that provide nectar and pollen for adults. Avoid unnecessary insecticide use, particularly broad-spectrum products that can kill beneficial predators. A garden containing diverse plants and a moderate natural insect population provides food and habitat for lacewings.
