Tramea loewii (Odonata: Libellulidae), a dragonfly newly arrived in New Zealand

Abstract

Two adult females of the large, migratory dragonfly Tramea loewii were observed at Lake Rotokawau, Northland in 2005 and 2007. Larvae found at nearby Lake Waipara in 2007 indicate the species had bred in New Zealand. Given appropriate climatic conditions, this species may be expected to expand its range within the northern reaches of the country. Queensland and New Caledonia are likely sources for the New Zealand population. Morphological characters are provided to enable identification of adults and larvae in the field.
