We look at the huge collection of insects housed at Landcare Research in Auckland. This fascinating resource contains over 6 million specimens, both native and introduced. It acts as an enormous library for scientists, allowing them to study the range of insects that are found in New Zealand – and the collection keeps growing, with the discovery of around 100 new insect species in this country every year. It is the job of the scientists at Landcare to find out how special these insects are.
We meet some of the more fascinating insects that live in New Zealand. Did you know that there are mummies in the New Zealand bush and that Māori used to burn them to make the ink for moko? The mummies are mummified caterpillars, dried and preserved by one of our native fungi species.
Check out our delicate scale insects. With no legs and no wings, they live in the bark of trees. The only part you will ever see is the small anal tube poking out of the bark and dripping with sweet honeydew.
We also meet Fred the Thread – the world’s thinnest caterpillar. A native of the Waikato peat bogs, scientists had to go on quite a detective hunt to figure out what sort of species Fred actually is. This context also looks at conservation. We explore why New Zealand came to have such unique ecosystems, dominated by birds. With so many interesting and wonderful native and introduced species, we need to understand the parts they play in our ecosystems and, in particular, how some of the introduced species can cause harm to our native flora and fauna. The work that scientists do in finding, classifying and recording native and introduced species is a critical part of this.
We also look at some of the more difficult concepts in conservation – should we conserve something that causes disease, like some of our native fungi do?
This context covers topics in biology and geology and the cultural importance of our native fauna. We learn about classification – how do scientists name species? We focus on some of the species that can only be found in New Zealand and find out how scientists work to conserve them. We also look back in time to the formation of New Zealand and how ancient species such as the tuatara come to be here.
