Definition of neuropteran in US English:



  • A predatory flying insect of the order Neuroptera, such as a lacewing or alderfly.

    • ‘The life cycle of neuropterans includes four very distinct stages: egg, larva, pupa, and adult.’
    • ‘Because of this, some neuropterans have been successfully used in the biological control of crop pests.’
    • ‘Zygopterans and tabanids were absent, and coleopterans, neuropterans, trichopterans, hemipterans (true bugs), and anisopterans were rare.’
    • ‘The first neuropterans are believed to have appeared during the Permian, almost 300 million years ago.’
    • ‘Shelob could well belong to a neotenic neuropteran species in which cocoon-spinning ability has been directed towards prey capture.’


  • Relating to or denoting neuropterans.

    • ‘These have been neglected in studies on neuropteran anatomy, and many aspects of their biology are likewise obscure.’
    • ‘There are two different kinds of neuropteran eye, with and without distal rhabdomeres, which can be expected on anatomical grounds to function differently.’
