A belated response to Zoe Hunter's article ‘All in a flutter over rare sighting' in The Weekend Sun May 2 edition about the blue moon butterfly.

I, too, was privileged in having blue moons visit me.

I spotted one on my lawn on May 6 and about 15 on my lantana lavender swirl the next day. My husband and a visitor witnessed them too.

Also, an Ongare Point friend saw more than one in his garden about the same time - and so did another of my friends at a Tuapiro Rd address.

She said several landed on fallen fruit under one of her trees.

I would say the ‘blue moon' name doesn't come from the butterfly's rarity but more likely stems from the blue encircling the white on the wings.
