Lacewings are commonly found in grass, weeds, and on the foliage of trees and shrubs.
Lacewings are flying insects with lacy, netted wings that extend in an oval beyond their
slim bodies. Adults of this predaceous insect are commonly referred to as green lacewings and
they measure about 1 inch long. The larvae are often referred to as aphid lions. Most adults
are greenish in color and have golden-colored eyes. The eggs are unusual in that each egg is
laid on the end of a tiny stalk. Lacewing larvae feed chiefly on aphids and also on mites,
mealybugs, whiteflies, leafhoppers, and thrips, among others. The winged adults do not feed
on insects; they feed only on nectar, pollen, and honeydew from flowers.
Lacewings and their larvae cause no damage to plants. No preventive measures are
needed, and you can attract them to your garden by planting nectar sources.
