Morphology of the immature stages and biological cycle of Ungla binaria (Neuroptera: Chrysopidae)

Abstract

Five species of Ungla Navás have been described for the Neotropical region, two of which are cited in Argentina, Ungla argentina (Navás) y Ungla binaria (Navás). In the present study, the external morphology of the immature stages of Ungla binaria is described and illustrated, providing details of the larval chaetotaxy. Data on the life cycle are given and two keys are included, one for the identification of larval stages of U. binaria and the other for larvae of the third stage of the two species found in Argentina.
