Where do monarchs best cacoon?

Monarchs best cocoon in sheltered locations that provide protection from predators and harsh weather. They typically choose the undersides of leaves, branches, or fences, where they can securely attach their chrysalis using a silk thread. These locations are often in areas with ample sunlight and close to milkweed, their primary food source for larvae. The safety and environmental conditions of the site are crucial for the successful metamorphosis into adult butterflies.
