The moths of Quail Island (Otamahua): A faunal comparison of an island under restoration with other sites on Banks Peninsula

Abstract

The Lepidoptera (moths and butterflies) of Quail Island located in Lyttelton Harbour, Banks Ecological Region, Canterbury, New Zealand were surveyed between 2007 and 2009. Four other Banks Peninsula sites were also sampled. In total, 146 species of Lepidoptera were found on Quail Island, which is currently undergoing ecological restoration. This is relatively rich for a small island with limited habitat diversity, but not as rich as nearby Banks Peninsula sites. None of the known Banks Peninsula endemic moths were recorded on the island. Recommendations are made for additional plantings to encourage the establishment of greater numbers of moth species and particular moth species are suggested for reintroduction to the island.
