The vision of the Moths and Butterflies of NZ Trust is to ensure that Aotearoa/New Zealand’s ecosystems support thriving moth and butterfly populations. In the past there has been little research done into the butterflies and moths of New Zealand and we are changing that.

From the inception of the trust until 2020 we were tagging monarch butterflies, and in some parts of NZ transects were being walked. With people walking transects, the data collected will show the numbers and locations of our endemic and introduced Lepidoptera species. Over future years we will be able to see any shift in population and if the various species are increasing or on the decline. But since embarking on this project, we soon learned that New Zealanders have to be able to identify our butterflies and diurnal (day-flying) moths first!

Butterfly transects were devised in 1973 by the Centre of Ecology and Hydrology in the UK. According to the CEH, the information gained from transect monitoring is invaluable, especially if the same transect is walked for many years. Regional and national indices are generated, and early warnings generated of species’ decline, at a time when conservation action can be most effective and before species are lost from whole sites and areas.
