Lacewing eggs are deposited at the end of a long hair-like stalk which is attached to the leaf. This prevents the larvae from eating one another as they hatch. Adult lacewings are greenish and about 3/4" in length. The wings are transparent with many veins that are visible. Lacewing larvae are elongate and have large mandibles that resemble sickles. They are slow, soft bodied and some species have raised bumps. They are often called aphid lions and feed on aphids and other small insects and eggs.
