In many parts of the country, a monarch caterpillar pops up as rarely as a blue moon - but in Christchurch, Napier, Wellington, and a few other spots, people are inundated with these cute crawlers.
So New Zealand's Monarch Butterfly Trust has set up a Facebook page to match up people with a caterpillar surplus, with those with a shortage.
Jacqui Knight from the Trust joins us to explain why it's a good idea to spread the monarch love, and how people can get involved.
