    Brown Lacewings

    Hemerobiidae is a family of Neuropteran insects comprising approximately 500 species in 28 genera, commonly known as brown lacewings. Adults are typically yellow to dark brown in coloration, with some species exhibiting green hues. They are small insects, with most species having forewings 4–10 mm in length, though some reach up to 18 mm. Both larvae and adults are predatory, feeding primarily on aphids and other soft-bodied insects. The family is distinguished from the similar Chrysopidae (green lacewings) by wing venation patterns, specifically the presence of numerous long veins with two or more radial sectors and forked costal cross veins. Some species have been employed as biological control agents, including Micromus tasmaniae which is commercially bred for pest management.

  • Hemerobiiformia

    Lacewings and Allies

    Hemerobiiformia is a suborder of Neuroptera comprising lacewings, mantidflies, and related families. Traditional classifications grouped these insects separately from antlions and owlflies (Myrmeleontiformia), but 2014 phylogenetic studies using mitochondrial DNA revealed Hemerobiiformia to be paraphyletic, with some lineages more closely related to Myrmeleontiformia than to other Hemerobiiformia. The Osmyloidea, previously placed here, appears to represent a basal lineage outside both groups. The suborder includes families such as Hemerobiidae (brown lacewings), Chrysopidae (green lacewings), and Mantispidae (mantidflies).
