Abstract

The endemic Megaleptoperla diminuta (Plecoptera : Gripopterygidae) was numerous on introduced watercress, Nasturtium microphyllum in Waikoropupu Springs, New Zealand. Adult females laid eyed ova. There appear to be about 15 nymphal instars and a non-seasonal, one year life cycle. Ovoviviparity and viviparity in Australian and New Zealand Plecoptera and Trichoptera may be associated with seasonal aquatic vegetation and fluctuating water levels.
