Hemerobiids, commonly known as brown lacewings, are important predators of aphids and other insects. The potential of hemerobiids in applied biological control has not been studied in depth except in few species. They can be recognised by the following combination of characters:

    

Most of the common hemerobiids are brown or greyish and can be easily recognised, but some such as Notiobiella spp. are pale green and very similar in appearance to chrysopids and easily mistaken for chrysopids. Very few species have been utilised in applied biological control. Micromus igorotus Banks has been found to be a very effective predator of the sugarcane woolly aphid, Ceratovacuna lanigera Zehntner, in southern India.
