I was able to show students from schools all over the South Island recently at a THE $100 Landcare Research workshop at Orokonui Sanctuary, part of the MothNet programme, which aims to monitor ecosystem health in our forests using data from the light trapping of moths. It is an ambitious but realistic programme that was kicked off at MOTH Orokonui in late October by By Brian Patrick – along with a compelling story leader Dr Barbara Anderson. n 1992, as the Department of and justification.

We 5 have good knowledge of both their connections with the native flora and Learning about different landscapes and our special ecosystems nationwide.” Lepidoptera (butterflies and moths) is the third largest group of insects MOTHS in NZ with over 2000 known species. 92% of NZ’s moths are endemic, i.e. found nowhere else in the world. Their largely nocturnal behaviour means moths are often overlooked. Their short life-cycle and good mobility mean their distributions often show clear geographic relationships with measurable environmental factors. Despite the many unique and intriguing moth species in NZ there is only a small number of professional lepidopterists. Accordingly, we know relatively little about the distribution of moths, moth ecology or the potential impacts of artificial light on them. Each species has specific food and environmental requirements which it needs to survive. Important environmental factors for moths are food-plants, nectar sources, temperature, humidity, and wind speed.
