City of bugs
In 2019, students from three Dunedin primary schools teamed up with University Otago scientist Dr Cynthia Winkworth to complete two goals: to discover which invertebrates were living in Dunedin’s city and park environments and to find a peripatus (ngāokeoke or velvet worm).

Peripatus are really unusual invertebrates. They’ve been around for 500 million years but are only found in Dunedin and two other cities in the entire world!
The students surveyed two ecosystems: their school and a bushy park. They used three different survey methods at each site. Students learned how scientists work very carefully as they systematically collect data and ensure that it is accurate and can be compared.
Peripatus/ngāokeoke
New Zealand peripatus (Peripatoides novaezealandiae), commonly called velvet worms, are unusual in that they are little changed from 500 million years ago and have their own phylum: Onychophora. They can be found throughout New Zealand, mostly in cool, shady and damp areas, and only come out at night to prey on other invertebrates, which they catch with jets of sticky fluid.
For more information on peripatus, see this Predator Free NZ article Peripatus is a sharp-shooting ‘living fossil’.
Back in the classroom, they had to learn how to interpret and use the data – looking for patterns, including similarities and differences.
The final task was learning how to be an effective science communicator. They created flyers and found other ways of sharing their findings with the community.

Activity ideas
Moths – learn how to collect moths and how to rear them to observe their life cycle. Watch a video on rearing moths and write a ‘how to’ guide in Rearing insects.
Label a wētā and cicada using the online interactives or download a paper alternative.
Read about the work that these students undertook on redesigning houses for wētā and then try the associated activity Building homes for tree wētā.
In Insect mihi, students write a formal introduction for an insect species including its relationship to other animals and the land.
Make a wanted poster to help enhance your students’ observation and scientific drawing skills.
