Lacewing is an insect with thin and delicate wings. The two main kinds are green lacewings and brown lacewings.
Some green lacewings have golden eyes, and some give off strong odors.
Brown lacewings have brown eyes and wings. It captures and feeds on aphids, scales, and other insects, and even on the eggs of other lacewings. Some larvae, called aphid lions, are used by farmers to kill agricultural pests. The full-grown larva spins a silk cocoon. Lacewings belong to the order Neuroptera.
