Neuroptera

[1] Neuroptera is grouped together with the Megaloptera (alderflies, fishflies, and dobsonflies) and Raphidioptera (snakeflies) in the unranked taxon Neuropterida (once known as Planipennia).

Many chrysopids, hemerobiids and coniopterygids eat aphids and other pest insects, and some have been used for biological control (either from commercial distributors, but also abundant and widespread in nature).

[6][7] Larvae in various families cover themselves in debris (including other insects, living and dead[8]) as camouflage, taken to an extreme in the ant lions, which bury themselves completely out of sight and ambush prey from "pits" in the soil.

As in other holometabolic orders, the pupal stage is enclosed in some form of cocoon composed of silk and soil or other debris.

Neuropterans first appeared near the end of the Permian period, as shown by fossils of the Permithonidae from the Tunguska basin in Siberia and a similar fauna from Australia.

[10] The genus Burmaleon is described from two fossils of Cenomanian age Burmese amber, implying crown group radiation in the Early Cretaceous or earlier.

A phylogenomic analysis published in 2023 confirmed the topology of the neuropterid orders and found the relationships between the families of Neuropterida as shown in the following phylogenetic tree.

[22] The use of Neuroptera in biological control of insect pests has been investigated, showing that it is difficult to establish and maintain populations in fields of crops.

[25] The New Guinea Highland people claim to be able to maintain a muscular build and great stamina despite their low protein intake as a result of eating insects including Neuroptera.
