Green Lacewing
Beneficial insect · Predator
Green lacewings are delicate insects that are especially valuable in vegetable gardens, orchards, and flower borders. Their larvae are active predators of several common garden pests. Adults are often seen near lights at night or resting on foliage.
How to identify it
Adults are light green with long antennae, golden or coppery eyes, and large clear wings with a net-like pattern. Eggs are laid singly on the tips of fine stalks attached to leaves or stems. Larvae are narrow, tan to brown, and have curved jaws used to grab prey.
How it helps your garden
Lacewing larvae feed on aphids, thrips, whiteflies, small caterpillars, mealybugs, and insect eggs. They are sometimes called aphid lions because of how aggressively they hunt soft-bodied prey. Adults of many species feed on nectar, pollen, and honeydew.
How to attract it
Plant small-flowered herbs and wildflowers that offer nectar and pollen over a long period. Keep some ground cover and undisturbed spots where lacewings can shelter during the day. Provide a shallow water source or maintain light moisture in part of the garden. A varied garden with flowering plants and moderate prey levels helps lacewings stay and reproduce.
Tips
Eggs on little stalks are a good sign and should be left alone. Because adults and larvae look very different, learn both stages before removing unfamiliar insects. Night lighting can attract adults, so you may notice them on walls or screens near the garden.
