Conteúdo:	Can larval lacewings Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) be reared on pollen? The aim of this study was to verify the viability of exclusive use of elephant grass pollen, Pennisetum purpureum (Schum), to feed larvae of the lacewing Chrysoperla externa (Hagen, 1861). The insects were kept at 24ºC and the duration and survival rate of each instar and the larval and pupal phases were recorded. The diet provided complete development of the larvae. The average duration of the first and second instars was the same (6.9 days), while the third instar lasted an average of 10.0 days and the pupal phase 13.2 days. The average survival of the larvae was above 80% for the first, second and third instars, and 70.0% and 33.3% for the larval and pupal phase, respectively. These results indicate that the exclusive use of elephant grass pollen can provide complete development of the immature stages of this predator
