The adult is very similar to the green lacewing but brown and about half the size.
The larvae of this lacewing are longer and thinner than the green lacewing larvae and do not camouflage themselves. They are a cream colour with light brown stripes, or may be brown with cream-coloured spots along their sides. They have a small head and the body tapers into a long tail. They have large jaws, making them look like ferocious, miniature crocodiles.
Adult size: 6-10 mm
