The Hemerobiiformia are a suborder of insects in the order Neuroptera. The phylogeny of the Neuroptera was explored in 2014 using mitochondrial DNA sequences. The results indicate that the traditional Hemerobiiformia are paraphyletic, meaning that not all the members of the clade are considered to belong to it, in particular since it would include all the Myrmeleontiformia, with which the Hemerobiiformia were traditionally contrasted. The Osmyloidea, usually included in Hemerobiiformia, actually seem to represent a more ancient lineage basal to Hemerobiiformia as well as Myrmeleontiformia. The broken-up group is shown in the cladogram:

Dilaridae is a family of insects in the order Neuroptera, known as "pleasing lacewings". They were formerly placed in the superfamily Hemerobioidea. But it seems that the Dilaridae are a rather basal member of the Mantispoidea, which includes among others the mantidflies (Mantispidae), whose peculiar apomorphies belie that their relationship to the pleasing lacewings is apparently not at all distant.

Drepanacra is a genus of lacewings belonging to the family Hemerobiidae.

Drepanacra binocula, known as the Australian variable lacewing, is a species of brown lacewing in the family Hemerobiidae, found across Australia and New Zealand, including Lord Howe Island, Norfolk Island and the Kermadec Islands.

Hemerobiidae is a family of Neuropteran insects commonly known as brown lacewings, comprising about 500 species in 28 genera. Most are yellow to dark brown, but some species are green. They are small; most have forewings 4–10 mm long. These insects differ from the somewhat similar Chrysopidae not only by the usual coloring but also by the wing venation: hemerobiids differ from chrysopids in having numerous long veins and forked costal cross veins. Some genera are widespread, but most are restricted to a single biogeographical realm. Some species have reduced wings to the degree that they are flightless. Imagines (adults) of subfamily Drepanepteryginae mimic dead leaves. Hemerobiid larvae are usually less hairy than chrysopid larvae.

Hemerobiinae is a subfamily of brown lacewings in the family Hemerobiidae. There are about 5 genera and at least 60 described species in Hemerobiinae.

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
