How long do monarch butterflies live NZ?
The butterfly has a lifespan of 60–70 days during the summer, but this extends to 6–7 months if the butterfly pupates in autumn. Monarch butterflies in New Zealand do not follow the same migration pattern as their northern relatives. They have adapted their migration behaviour to suit local conditions.
Why do butterflies die when you touch them?
A butterfly’s wings are covered in scales, which are shed over time as part of the insect’s life cycle, Reetz said. For some butterflies, the scales can come off if you touch the wings, which can cause some damage but won’t kill the butterfly. Touching monarchs’ wings does not cause them to lose scales.

Painted lady: 12 months

How long does a monarch butterfly stay in its pupa?
Pupa (Chrysalis; 10-14 days) During the pupal stage the transformation from larva to adult is completed. Pupae are much less mobile than larvae or adults, but they often exhibit sudden movements if they are disturbed. Like other butterflies, Monarch pupae are well-camouflaged, since they have no other means of defense against predators.
