Conteúdo: 	The Chrysopidae family comprises natural enemies of agricultural and forest pests. This work evaluated the prey consumption and development of one species, Chrysoperla externa (Neuroptera: Chrysopidae), fed with Spodoptera frugiperda (Lepidoptera: Noctuidae) or Anagasta kuehniella (Lepidoptera: Pyralidae) in laboratory conditions. Chrysoperla externa was reared with: newly laid or one-day-old S. frugiperda eggs; newly hatched, one- or two-day-old S. frugiperda larvae; or one-day-old A. kuehniella eggs. The number of prey offered varied with the development stage of C. externa. Larvae of C. externa and prey were transferred every 24 hours to fresh vials. Duration of the larval stage of C. externa was similar when fed with newly laid or one-day-old S. frugiperda eggs, newly hatched S. frugiperda larvae or A. kuehniella eggs. Larval survival of C. externa was 90.0 ± 2.5% when fed with A. kuehniella eggs and 73.3 ± 18.32% with newly hatched S. frugiperda larvae. Chrysoperla externa consumed high numbers of eggs of A. kuehniella and high weights of one-day-old eggs or newly hatched larvae of S. frugiperda or eggs of A. kuehniella. Chrysoperla externa could not be successfully reared in the laboratory on one- or two-day-old S. frugiperda larvae, but could on eggs of both preys and newly hatched S. frugiperda larvae.
