Lacewings are slender, bright green flies with delicate veined wings and long antennae. Adult lacewings eat pollen, nectar, and the honeydew of aphids and scales. Some species also feed on pests. Lacewing larvae, commonly called aphid lions, are about 3/8″ long with large heads and yellowish-gray, mottled brown bodies. These hungry larvae readily consume many troublesome garden pests including aphids, thrips, mites, and whiteflies. They eat insect eggs as well as the insects. Lacewing eggs are easy to identify; they are held aloft on a threadlike stalk attached to a leaf. There are 1 to 5 generations per year, and they are found throughout North America.
