Lacewing eggs Eggs of some lacewings are laid on threadlike stalks to prevent cannibalism among newly hatched larvae. They are usually laid in clusters and easily found on leaf surfaces. Some species lay single eggs without stalks. Lacewing larva Lacewing larvae pierce the skin of their prey with two large sickle shaped jaws. They use them to inject saliva and suck out liquified host body contents.
Aphids are the preferred food for lacewings.
They will eat several hundred during their development. Most ladybeetle eggs are in small clusters and can be found on the undersides of leaves. They are usually orange and stand upright from the leaf surface. Convergent ladybeetle larva Larvae of many lady beetles are alligator shaped, black and orange, and have chewing mouthparts. Aphids are the preferred food but they will consume other insects.
