What do monarchs need when hibernating in the montains of Mexico?

When hibernating in the mountains of Mexico, Monarch Butterflies need a suitable microclimate that provides protection from harsh weather conditions, such as cold temperatures and strong winds. They seek out specific types of trees, primarily oyamel firs, which offer shelter and maintain a stable temperature. Additionally, they require a high humidity level to prevent dehydration during their hibernation period. These conditions help ensure their survival until they emerge in the spring to continue their migration.
