Hemerobius is a genus of lacewings in the family Hemerobiidae. It is found throughout Europe and North America. Like most lacewings, both the larvae and adults are predatory, primarily eating acarines, scale insects, psyllids, aphids, thrips, and the eggs of lepidopterans and whiteflies.Names brought to synonymyHemerobius elegans Stephens, 1836 Hemerobius elegans Guérin-Méneville, 1844
