The overwintering stage in New Zealand starts in April or May. This is when swarms of Monarch butterflies form regularly to overwinter at places around the country.
I’m Maria Romero. This passion for Monarch butterflies started back in 2010, just before the devastating earthquake in Christchurch. I remember discovering my first swan plants at a Playcentre I went to with my children. There was a science table with eggs and caterpillars on the plant.
