Almost all of the butterflies in New Zealand are native and most are endemic. Compared to big, colourful species from other countries, our native butterflies are small and secretive.
Our elusive native butterflies
Did you know that New Zealand has only a few butterfly species? Scientists think that they are relatively recent arrivals, either blown in from Australia or flying in via New Caledonia. In spite of the small number, there’s a lot we don’t know about our butterflies. The alpine habitats, camouflage and sluggish life cycles of our native butterflies make them tricky insects to find and study in the wild. Even our well known butterflies have experts scratching their heads about their habits.
Citizen science opportunities
Some of the people helping to fill the gaps in our butterfly knowledge are citizen scientist groups like the Moths and Butterflies New Zealand Trust Pūrerehua Aotearoa (MBNZT), led by Jacqui Knight. Volunteers gather information on monarch populations and host plant availability, and are working to prevent the extinction of the endeminc forest ringlet. From 2005–2021, MBNZT conducted a tagging programme to establish whether there were migration patterns within the monarch population. Tagging data has shown that the majority of monarchs overwinter in the area around where they eclose. The MBNZT welcomes school involvement. Students become citizen scientists by following established protocols – such as setting up transects and observing monarchs in the school garden as part of the international Monarch Larva Monitoring Project.
Ahi Pepe MothNet is a Participatory Science Platform initiative that investigates the distribution and ecology in New Zealand. It also has established protocols to ensure school students collect robust data about our native and introduced moth species.
Butterflies and alternative conceptions
Students hold a few alternative conceptions regarding butterflies and moths. The articles Differences between butterflies and moths and New Zealand moths address some of these issues. A second area, life cycles and metamorphosis, are compared and contrasted in the interactive Monarch butterfly life cycle and the activity White butterfly life cycle. A third area, toxicity, is covered in Butterfly defence mechanisms.
A butterfly story in a primary classroom shares the account of a year 4 class as they took action to become butterfly warriors to protect butterflies in their school environment. Ideas from this experience formed the basis of two unit plans – one for lower primary and another for upper primary. A PLD webinar highlights the science skills and capabilites covered in this citizen science endeavour.
