While they are not listed as endangered or threatened by the IUCN Red List, their populations can fluctuate due to factors like:
* Habitat loss: Deforestation and urbanization reduce their breeding and feeding grounds.
* Pesticide use: Insecticides can harm both caterpillars and adult butterflies.
* Climate change: Changing weather patterns can disrupt their life cycle and food sources.
Despite not being threatened, it's important to protect and conserve their habitats to ensure their continued presence in our ecosystems.
